Overdosing on Niacin: Side Effects, Toxicity, Symptoms, Poisoning

I promised to write one column about the side effects of vitamin B1 (thiamine), vitamin B3 (niacin, niacinamide), vitamin C, and vitamin D (cholecalciferol). Deficiency in these four vitamins causes beri beri, pellagra, scurvy, and rickets respectively. I started with vitamin D because it causes the most problems. Vitamin B3 (niacin, niacinamide) is second because it is the most troublesome.

The situation with niacin is what it is. The Food and Nutrition Board has set the RDA for niacin at 20 mg/day and the upper safe limit (UL) at 35 mg/day. This is far and away the closest for the four most important nutrients. At the same time, niacin is the only vitamin embraced by mainstream medicine. It is used to treat high cholesterol. Heart doctors prescribe 2000 mg/day niacin for this purpose – more than 50 times the UL. Are we supposed to believe that some people can take 2000 mg/day with no problems and others have to both make sure that they get 20 mg/day (the RDA) without exceeding the UL of 35 mg/day? Oddly enough, the answer to this question is yes.

Niacin is famous for causing flushing. Rapid absorption of as little as 35 mg of niacin (think 35 mg of niacin with a hot coffee on an empty stomach first thing in the morning) can cause flushing. The duration and severity of flushing is proportional to the dose. A severe flush can be fearfully painful – an unforgettable experience. A mild flush could possibly be described as a pleasant experience by an unusual person – a feeling of warmth accompanied by tingling. Here is a fairly comprehensive list of other side effects listed by authorities:

Itchy feeling spots on the skin (skin looks perfectly normal upon inspection)
Dry feeling spots on the skin (skin looks perfectly normal upon inspection)
Fainting
Rapid heartbeat
Low blood pressure
Nausea
Diarrhea
Vomiting
Ulcers
Liver malfunction
Nervousness
Panic
Anxiety
Headache
Tooth pain
Gum pain
Decreased Thyroid function
Blurred vision
Lazy eye

I read this information and was well aware of the side effects before I started taking niacin. The information was useful, but lacking in many important details. So, once again, from here on the story is based on my personal experience. It will take time to tell how relevant my experiences have been.

I’ve been taking niacin and reacting to niacin side effects for 12 years. Here are side effects I believe were caused by niacin that I experienced and aren’t on the list above:

Euphoria
Talkativeness
Excitability
Sleeplessness
Restless legs


Early on, I was taking over 1000 mg/day of niacin and feeling great. Then one day, for no obvious reason, after months supplementing near 1000 mg/day, nausea started in the morning right after I took my daily supplement. The nausea intensified throughout the morning until it became disabling. I ended up home and in bed. There, the nausea further intensified until it became agonizing. Finally, over the course of an hour or two, I vomited several times. The vomiting ended with a bright yellow fluid that I suspect is bile. When my wife was niacin poisoned, she also vomited this yellow fluid. I believe it is characteristic of the vomiting caused by niacin. One day I was taking regular doses of niacin and feeling fine, and the next day I was deathly ill. Once the vomiting was over, my recovery was astonishingly rapid. I was back to work feeling well the next day. I told my boss I had a 24-hour stomach bug. Despite great care, this happened to me two more times while taking regular doses of 500 to 1000 mg/day of niacin.

In recent years, I’ve been taking 100 to 1000 mg/day of niacin for several days in a row in short, intermittent bursts separated by weeks and months with mostly none interspersed with several days in the 60 to 125 mg/day range. When I do take it, I like to take the 60-120 mg/day dose of straight release niacin first thing in the morning with a cup of hot coffee on an empty stomach. That way I get the strongest possible reaction. I typically get a very mild flush that, to me, feels good. Less frequently I experience nothing or a severe flush. Rarely, I have experienced a 5 to 15 minute bout of intense nausea along with a severe flush.

In recent years, niacin reliably accelerates my heart rate and makes me less inhibited. I have trouble falling asleep. These effects last for about 24 hours.

On average, as the years have passed, I have been taking less and less niacin and experience a wider range of side effects at a wider range of severities. My testimony directly contradicts the common claim that niacin side effects dissipate with time. It’s not just me. I persuaded friends and family members to start taking niacin at 250 to 500 mg/day doses. Today, many of them have quit taking niacin supplements because of side effects. At the same time, I know several are taking 1000 mg/day niacin to control cholesterol and reporting no problems with side effects.

In summary, the list of niacin side effects is long. The list is so long that I recommend that anyone taking niacin stop taking it for 3 to 7 days at least once/year just to see if niacin is causing any trouble. Stopping for such a short time is not known to do any harm, and symptoms assumed to be a result of aging may actually be niacin side effects. I’ve taken 500 mg/day for several days with no side effects and have taken a single 60 mg dose that’s ruined most of a day. So, in my experience not only have I found that niacin tolerance varies widely from person to person, I’ve found that niacin tolerance in individuals varies widely. As a result, I’ve found niacin to be the hardest to use of the four vitamins associated with deficiency diseases.

I have been taking 2000 mg niacin for about 5 years. I have told several doctors and they do not object to this dose. However I always take Vitamin C with niacin. I usually take two doses a day: 1000 mg Niacin and 2000 mg of Vitamin C. All of my liver tests have been normal. I usually take the first dose just before going to sleep along with a glass of water. I awake in the middle of night and take the other dose along with another glass of water.

When I first took the niacin and Vitamin C, I had the classic flushing symptoms. But after a few days, it has mostly disappeared. I use to have severe hay fevers complete with allergy shots and prescription drugs. Since taking the niacin my allergy symptoms are greatly reduced and I do not take shots or prescription drugs. I still have allergy symptoms but they are greatly reduced.

If my stomach is upset at night, I do not take the niacin and Vitamin C. But this only happens a few days out of the year.

I decided to take niacin after reading about Dr Hoffer use for various diseases. Here is the link:

Dear Anonymous,

Thanks for posting a comment. I'm glad that your doctors do not object to your dose of 2000 mg/day of niacin. They should not. It is the prescribed dose for controlling cholesterol.

I'm glad that you can take 2000 mg/day without side effects, and that this treatment has helped you to control your allergies.

Finally, I'm glad that you take vitamin C and niacin together.

Thanks also for the link to Dr. Hoffer's writings at Dr. Saul's website. I have studied most everything they have written, and am always on the lookout for what comes next. You can see from the doctoryourself.com website that Dr. Saul has just published two new books. I'm looking forward to reading them.

I had a heart attack in 1993 and a triple bypass op in 1994, using the same incision route as my 1987 quad bypass surgery. At times prior, my cholesterol had been measured as high as 458 and triglycerides at 900+.
I have been taking 1 gram of niacin fast release 3 times a day since 1994. I also take 2 x 1 gram of C each day, along with some more benign supplements.
The only identifiable side effect has been a momentary flushing shortly after taking the niacin. The flushing period is only a short time and missing completely if I am working or exercising.
I am seeing a cardiologist twice a year for blood tests and take prescription Zocor. My HDLs typically are 75 and LDLs around 30. So I assume I am lucky - minimal side effects and great results. The only problem is finding the fast release niacin. The stores I have checked recently have only non-flush niacin, which has a significantly higher hepatic complication side effect. I may be forced into the slow release kind because I can't find the good stuff.

I came to this blog because I've just started taking Niacin (started at 100mg/ twice a day and have increased to 200mg/twice a day) and I too have noticed such a severe decrease in my allergies that I've stopped taking my over the counter allergy medication.

Based on the cost of niacin to otc allergy medication I'll happily deal with the 30 min flush I get from the niacin (which incedently men is supposed to help stimulate hair growth).

Thank you for your information. I just took my first dose of 100 mg about 45 minutes ago and the intense itching is starting to subside. I was about to jump into the cold shower to get rid of the feeling but took the dog out for a walk instead to get my mind off of it. I am to take this dose 3 times a day for 4 days and then increase every 4 days up to 500 mg 3 times a day. My mother could not tolerate niacin and I am hoping to "stick it out" as my liver enzymes were elevated with statins and cholesterol and triglycerides are way up. Your information encourages me to think that I can get through the side effects with a little patients and I will try the aspirin. Has anyone tried to use Benadryl for the itching?

Virginiac,

Thanks for stopping by with your comments. I believe most people can maintain good health without suffering any vitamin side effects. Niacin alone is not the best way to solve your problems with cholesterol and triglycerides. You should also be getting optimal doses of vitamin D (lots of sunshine), 2000 mg vitamin C per day in the morning and evening (4000 total), and 100 mg/day of thiamine in the morning and evening (200 mg/day). Since niacin is bothering you, why not use the lower dose I recommend and add in the other three?

 
At 8:19 PM, Blogger virginiac1963 said...

I am going to try that (vitamins C,D and thiamine)because I have now had two episodes of intense (and I mean intense) head-to-toe beet red niacin flush on 100 mg three times a day. Tomorrow I am supposed to increase to 200 mg three times a day. It is so intense that I don't know if I can take it much longer.

 
At 8:10 PM, Blogger Steve said...

Virginiac,

Thanks so much for returning to share your experiences. I am very sorry that the medical profession is not more flexible. I don't know why they insist on such high doses despite side effects and then switch to 100% statins and quit niacin altogether if the high dose doesn't work out.

If the four vitamin combination doesn't get your lipid levels into the range of normal, I recommend adding a statin to the vitamins. Adding a statin drug to the vitamins will lead to further improvements if the vitamins alone are unable to get the job done. Keep on coming back to update the blog on your progress.

Thanks again,

Steve

Thanks Steve for your encouragement. As it turns out, I happen to work in the medical field and I know how rigid they can be with the protocols. I wound up asking the doctor to take me off of Niacin as I could no longer handle the side effects and am now taking gemfibrozil and fish oil supplementation. I know that there are some people who have been able to lower there lipids dramatically with niacin supplementation, unfortunately I am not one of them. Good luck to all of you out there. Stay healthy!

Dear Virginiac,

Thanks for stopping back. It is highly likely that the troubles you are having maintaining blood levels of important lipids within the normal range is due to a deficiency of vitamin C, vitamin D, niacin, and/or thiamine. I strongly recommend that you get all four of these vitamins. The doses I recommend for starters are at the upper limits set by the food and nutrition board. 95% of the population manages these doses without side effects. These are: 100 mg of thiamine twice per day, 2000 mg of vitamin C twice per day, 250 mg time release niacin two or three tablets per week (the time release is very important. Do not take straight release). Vitamin D should be gotten primarily from the sun. Full body exposure for just a few minutes between 11 am and 3 pm most days the sun is out works wonders.

I am relatively new to niacin for cholesterol control; I have tried Zocor (became really incontinent, bloated...) then tried Lipitor 20 mgs a day tolerated it for 2 months(got some headaches and headaches on one side of the face a nd head later found out were migraines and lastly nose drains it was like I had a mucus hose attached to the inside of my nose)Now I tried Niacin 500 mg 2 times a day for the last 3 months, stopped this morning after a couple of days very uncomfortable; this morning at 4 am got out of bed with very hard chest pains and back, arms, worst the left and some breathing problems...
I am hoping is the Niacin.

How very interesting that I have ran across this blog. I was searching for information on Niacin and what effects it has on kidneys and ....well, Here I am!

My Dr. initially started me on 500mg of the -Flush Free Niacin- due to my triglycerides are high. I have taken that dosage for 3 months and returned to have my blood rechecked. My labs came back the same everything was normal except--- now my triglycerides went up higher.

It seems like I get a pain in my lower back on the right side now that my dosage of Niacin has been moved to 1000mg (I take it at night, prior to bed, per my Dr.orders) Have you ever noticed something similiar?

Thanks for the info. I started taking niacin (100mg), for chronic treatment resistant-depression. It is the only thing that seems to help(all other anti-d's have failed or been too intolerable), and I can't quite believe it works though my partner assures me I am dramatically different. I had played around with food/etc thinking I had got the combination right (taking it on a full stomach at lunchtime, with a glass of cold water and avoiding anything hot, and especially chilli, or red wine then stupidly I had it before I had a bath and ended up staggering to the bathroom, vomiting (the same yellow bile you mention) getting diarrorhea and passing out,whilst having incredible sweats. It was worse than my many episodes sick with stomach bugs in Thailand; so I stopped it.
Yesterday I started again, and my mood and energy improved dramatically, and if it is placebo, it's doing one hell of a job. Thanks for the info, because it sounds at this dosage I shouldn't be too concerned.

Thanks.

Dear Anonymous,

Thanks so much for stopping by and sharing your experiences using niacin as an anti-depressant. Depression is a major problem and is difficult to treat. The nervous system depends upon vitamin C, vitamin D, niacin, and thiamine. You may want to consider adding vitamin D, vitamin C, and thiamine to the niacin you are already taking. Especially important is a form of vitamin B1 called TTFD. It's hard to find but well worth the effort.

I was especially moved by your side effect story - vomiting caused by rapid absorption of just 100 mg of niacin. This is a remarkably low dose. I totally believe it since a 100 mg dose on a cup of hot coffee and empty stomach recently had me lying on the floor moaning from the intense nausea. Happily I recovered in about 30 minutes and did not vomit.

I had to laugh out loud when I read about you taking your morning dose with coffee on an empty stomach for the 'full effect'. I also do the same thing (I take 500mg of instant release niacin a day, at one time). I get a furious flush, a bit of sting and often the itch. The itch I can do without, but I live for the 'flush', the instant mood and energy boost and the occasional euphoria. I also have depression and bipolar (I think the niacin can trigger slight hypomania, which is fine by me because hypomania=I can take on the world). My triglycerides dropped 70 whole points after a couple months, my total cholesterol dropped from 250-260 range, fasting, down to 215. My LDL didn't improve an awful lot and is still high, but my HDL raised so that my HDL/LDL ratio is finally normal.

I was wondering: Is it abnormal to develop skin abnormalities from taking niacin? I have three red bumps on my left hand, about the same circumference as a cocktail drinking straw opeing. They are almost perfectly round and started out feeling like a pimple that never quite comes to a head. Now they are painless (had them from 7-10 days now), flattening and slightly shiny on top.

From what I've read about niacin, it increases blood flow to the capillaries of the skin, which is what causes the flush. Perhaps this causes the skin, an excretory organ, to flush out impurities from the body? Who knows... just a thought I'd put out there.

Thanks for sharing your experiences and many warm, glowy, happy flushes to you! xD

Christine,

Fantastic comments!

I hope your red bumps are gone. They are not a reported niacin side effect. If they are a side effect, they will come and go in response to niacin dosage. Please let me know if withdrawing niacin causes bumps to disappear and restarting niacin causes them to reappear.

Since you liked this column, I hope you'll read my other columns and add sunshine (vitamin D), vitamin C, and thiamine to your daily routine.

Thanks again,

Steve

I have been on niacin therapy for over 2 years increasing the dosage to 2,000 mg 5 months ago. I have experienced the red bumps which I come to see are a dense thickening of the skin that are itchy. I tolerate rash on my legs, forearms and hands that at times is very uncomfortable. My HDL has been in the range of 49 - 53, my overal cholesterol began at about 293 and last reading 5 months ago was 233. I asked my physician if I could increase the doage to 2,000 mg to see if that would lower the LDL which is still over 200. Triglicerides are around 150. My skin is very dry and I use a lot of vaseline and moisturizers to control the itching which has been moderately successful. I will have my blood checked in a few weeks to see if things have improved. In addition to niacin I also grind flax seeds (6 Tablespoons)and make a pudding of it with 1/4 cup chopped walnuts, 2 teaspoons cinnamon and 1 healthy Tablespoon of honey, I also take 50 to 100 mg of CoQ10 and fish oil daily , eat no animal proteins or dairy, I occassionally choose to eat refined sugar but it is not a treat I allow myself with any regularlity as it suppresses the immune system, I make every effort to eat unprocessed food, whole foods are the best, I stay away from fried foods, only once in a while will I splurge on scallops that are deep fried or french fries. All of these efforts have been consistently used and I am still experiencing high LDL levels that my physician advises are dangerously high. If my blood work does not show improvement at the 2000 mg of niacin a day I plan to discontinue its use and try plant sterols maintaining all the other protocols I have mentioned.

Calabash Gal,

Also a fantastic comment.

I admire your willingness to tolerate niacin side effects.

Regardless of how you choose to proceed, you can also consider working to optimize vitamin D, vitamin C, vitamin A, and thiamine intake. I've written extensively about vitamin D, vitamin C, and thiamine. I haven't written much about vitamin A yet - I'm working on it.

Good luck and please keep in touch to let us know how you're doing.

Wow, I'm so happy to have found this blog! Hahahahaha! I market and sell an energy drink called Xs, which I knew had a little bit of niacin in it but didn't think too much of it until today! One of my co-workers said, "Jenny, isn't that your fifth Xs today?!! You had four yesterday!" and the other knew about the niacin and the funny red, itchy reaction my brother had to it MONTHS ago after drinking two. I had been having crazy itching!!! On my arms, thighs, and legs and also those bumps!!! "Like pimples" it is so irritating and I was so worried it was something else but I couldn't figure out what!! I feel like such a dork now, but this blog and people's responses have been helpful!

I tried 1000 mg of niacin last night for the 1st time. Had very bad flushing which felt like bad sunburn. Had to ice my skin with an icepack to tolerate the sensation.
But, I also had swelling under my eyes, big bags, like an allergic reaction.
Today, I feel like I had been hit by a train. Very low energy and something just doesn't feel right.
The whole episode lasted a couple of hours (though the swelling under the eys lasted much longer) and then even though the other syptoms subsided, I just feel exhausted and "beat up".
Has anyone else had these sort of reactions besides the flushing?
Can this mean that I am pehraps allergic to niacin?
Should I even attempt to take another dose today?
Frankly I am scared to try it.

 
At 8:54 PM, Blogger Steve said...

Dear Anonymous,

Other people have had similar reactions to niacin.

1000 mg is a large dose. I recommend 250 mg of time release niacin and I stress that it is critical to get the time release tablets.

I hope that you took ordinary niacin (not time release). Plain niacin at 1000 mg causes bad flushing in almost everyone.

So - provided your initial experience was with 1000 mg of niacin, I recommend that you go out and get 250 mg time release niacin tablets and try one a day.

Alfred,

Thanks for your comment. I'm glad you've been able to tolerate 1000 to 2000 IU of niacin for over eight years.

Forgive me for making assumptions, but I assume that you have significant health problems to motivate you to take so much niacin. Please consider adding sunshine, thiamine, vitamin C, and vitamin A to your supplement program. Just type cforyourself thiamine (or vitamin C, or vitamin D) to find other blog items I've written.

I have been directed to take 1000mg on a daily basis of Niacin for cholesterol maintenance . To avoid the flushing and hot flash I have been taking an adult Aspirin about 1 hour before the Niacin usually around bedtime. This seems to work fairly good for me.

I hope the author of this blog will read the paper I wrote on "Allergies and Schizoophrenia: Immune System Starvation?" published December 1981 in Dr. Abram Hoffer's magazine, Orthomolecular Psychiatry, now called Orthonolecular Medicine. The article is available online.

There appeared to be a negative correlation between allergies and some mental disturbances.

The subject of this study found allergies decreasing or eliminated with high dosage niaciin use. The study was terninated because of questions of heart function. However, the subject later resumed niacin use and was finally competely free of allergies, including asthma, hayfever and eczema. Type I atopic allergies.

Niacin dosage as needed went as high as 9 grams a day, but uaually much less.

Suspected but not proven: (1) Niacin elevates prostaglandins, especially prostaglandin E, a potent broncodilator. Other PGs may cause the elevated liver enzymes, and possibly aspirin, which suppresses some PGs, might alleviate this effect.

(2) IgE is the only immunoglobulin which does not require Complement for its function. Therefore if Complement is depleted, the body may try to use IgE to cope with allergens. Thus, what we call "hay fever." (It would be one of the higher numbered conplement compoonents.)

The trick to using niacin is to start low and slow. Don't raise the dose until you no longer get a flush at that level, Then go up just a little, maybe from 50 to 100 mgs, etc. The niacin is clearing out cholesterol, that's what causes the flush.

I have been taking 500mg-1000mg of time release niacin for the last three months to try and raise my HDL levels which have been under 40 the last two times I have had blood work. A few times I have had some nasty "flushing" episodes but I have gotten used to it now. I usually take a 500mg in the morning and one before going to sleep. I am glad I found this blog as I will try supplementing with vitamin C.

After discovering Dr. Hoffer online. I took my first ever dose of Niacin 500mg by the company Major, ( which are not time release). I thought I'd start with 500mg Niacin and twice that in Vitamin C at 1000mg. I experienced a very mild flushing, almost undetectable. I did enjoy the flushing experience . I may increase to 1000mg Niacin/2000mg Vitamin C. Maybe break up doses twice a day. Morning and evening? I believe the reason for flushing may be how toxic a person may be. My daily diet consists of organic raw (not cooked) greens such as kale, celery, bell peppers, broc., etc. brown rice, take probiotics, no junk food. no dairy, no gluten/wheat, no sugar, little to no coffee, and absolutely no processed foods. Nutrition has a lot to with well being period. I am a years into this lifestyle and will say I have not had a cold or flu in five years plus look many years younger, plus energy. I have suffered from occasional anxiety, etc. from my intense work load which is how I discovered niacin online articles. After a single dose I felt 100% mental calmness and rested easily. I am excited to report the news as the evenings I usually dwell on my days events, etc. Thanks.

I've been taking 1000mg of Slo-Niacin (time release) every day for a year for cholesterol. This week on my doctor's suggestion I upped the dosage to 1500mg. Not sure if this is related, but starting last night I've had severe vomiting. I've always been concerned about liver toxicity and have my liver enzymes checked annually. They've been normal so far (most recent test was 2 weeks ago). I think I am going to stop the niacin for a few days and once I am feeling ok, go back to the two 500mg pills/day regimen (instead of 3).

I've read many of the posts and I'm glad to have stumbled upon this blog. I have just 'reached' the 1000mg per day level by taking 500mg 2x pr day. I have been experimenting with niacin at various levels for the past 6 months after reading about it's ability to raise HDL levels. I started 5 or 6 years ago on lipitor (statin) and that brought my total chol. Down frm 230's to 170's. The HDL was down in lower 40's to upper 30' however and I would like very low cholesterol because I read that is when any arterial deposits start to get cleared out and reabsorbed. My last blood work just a few weeks ago had total HDL of 157, LDL 70 or 80 or somewhere around there and HDL 42. So that was with smaller very sporadic doses. I was not taking any for a few weeks before the test. I will try to maintain 1000 and maybe more for next 6 months and see what next blood work shows. One thing though, I read that vitamin C counters the cholesterol lowering/HDL raising effect of niacin??

I have taken 500mg niacin on and off for the last six months together wih 40mg simvisatain.
Three months back I started a sever left sided chest pain. When I stopped the statin the pain abated so I blamed the statin.
However, today when I took niacin, after a months break, the pain returned within 5 mins of taking the niacin !!
A hot water bottle helped to reduce the pain. BUT tomorrow I'll halve the niacin dosage, and report yhe result.

Hey mate, nice blog.
Im currently taking 500MG Niacin with Flush everyday. Everything is fine, just finished 1 month taking niacin.

My only concern is the liver problem as it can cause quite some damage. But people like you have taken it for god knows along time but had the 'normal' side effects.

Im just worried about the side effect after reading this. I am currently 18 years old. I take Niacin as it boost my energy everyday and the flush feels great!

Any advice if I should be worried about the liver problem?

Mr. Philo,

Niacin side effects, even liver damage, respond quickly when niacin supplementation is stopped. A full recovery is the expected outcome. So - you can go ahead and use the niacin without any fear of serious harm.

The problem is that niacin side effects can sneak up on you after months or even years of supplementation without side effects. I recommend a niacin fast (5 days without supplements) at least once per year. If niacin is the cause of any discomfort, the discomfort will fade during the fast and then return immediately when niacin is reintroduced.

Niacin is fantastically powerful. I'm really glad you are using it and doctoring yourself.

Don't hesitate to return and ask questions.

Steve

Steve,

With all due respect, are you a doctor, M.D. or N.D., or do you have any degree in nutritional counseling?

I ask this because some of your advice is just beyond the pale, and frankly, incredibly naive. You imply that only vitamins affect the nervous system...

"The nervous system depends upon vitamin C, vitamin D, niacin, and thiamine."

...leaving out b2, b5, b6, folate (not folic acid) and b12, among just some of the other co-factors.

In fact this entire posts reflects the fact that no one should be taking such astronomically high doses of niacin or niacinamide.

These aren't "side effects", they're EFFECTS.

Dear Anonymous,

I'm mortified that I have written posts that are being interpreted to mean that I believe that only vitamins affect the nervous system. I'm going to go through my posts and work to edit them to be more clear - starting with the sentence you quoted. For sure the other vitamins are awesome.

Indeed, this post on side effects highlights the downsides of extra niacin/niacinamide. Over the last couple of months, my tolerance for niacin has risen again and I'm back on a steady diet of 100 to 300 mg/day. I wouldn't be surprised if I'm stung by bad effects again. In the meantime, I'm happy with what I perceive to be good effects.

Regarding my credentials, what difference does it make? Would you think more highly of my blogs if I told you I was a Harvard M.D. with Ph.D's in both medicine and nutrition? I doubt it. I don't want readers to judge me, or what I have to say. I want them to get into the sunshine to try getting extra vitamin D, and I want them to take vitamin C, niacin, and vitamin B1 and get back to me with data.

Thanks for your comment,

Steve

Took 50g (half a tablet) niacin this morning on empty stomach with coffee with half a tablet of thiamin and half capsule of 5htp (a seratonin precursor available over the counter).
20 mins later - intense flushing while driving the car - looked like a giant tomato. Felt sweaty and shaky so stopped and went into a local pharmacy and bought some anti-histamine syrup (thought it was an allergy). Pharmacist was so concerned that she called an ambulance. Highly embarrassing - rash settled down while paramedic was examining me - he found raised pulse and slightly low blood pressure (must have been why I was light headed). I had no idea that Niacin could cause this reaction which was very unpleasant - the burning and fast heart rate was awful. I have taken lower doses of niacin before with no problems, so will start with quarter tablet (25mg) of niacin on its own with food and work up gradually, before I add any other supplements. I guess I have a low tolerance to it. I'm taking this to help with anxiety. This morning's experience didn't help with that!!

Hello!
I have been taking 250mg of Niacin in time release capsules for two days. I didn't know about the flushing reaction, I simply read it was a good alternative for depression/anxiety. The first day I didnt get any symptoms, but the second day I experienced what I think was a flush, but at least 3 hours after I took the Niacin. At first I thought it was some sort of allergic reaction to a strawberry shake I had, but it would be unlikely since I have never had any food allergies.
Now I don't know how to proceed. Should I reduce the dose, buy Niacin in non time released form, what should I do?
Also, what role does vitamin C play when you take it together with the Niacin?

I would like to weigh in. I started taking around 1000 mg of Niacin a day around a week ago. I'm now sitting the hospital with liver failure! I hope that you all, at the minimum, start taking it slow, and in a controlled environment.

Also, don't go for time-release capsules.

I started taking 100mg of niacin about a month ago and had a bad flush after taking it on an empty stomach. Learned to take it with meals and a baby aspirin and gradually worked up to 2000-3000 mg a day with no flushing. Then I started feeling queazy and soon was vomiting violently. I thought it was a stomach virus until the same thing happened then following week followed by a dramatic drop in blood pressure and severe , crushing chest pains. Spent the night in the emergency room. I haven't read much about others experiencing severe chest pains. Don't think I will continue the niacin!

Hi All
This is the 1st blog that I have seen that had comments from people that had adverse reactions to Niacin. By adverse reactions, I mean liver failure and vomiting. That is scary. But then I see that the liver failure resulted from the time release product, which Drs always say is toxic.
I have been taking Niacin on and off for years, mostly off, just to clean myself out. Lately I have started taking it again because I have diabetes and started getting tingling in my foot. The Niacin stops it(250mgs). I have just recently upped the dose to 500mgs and I just ordered a btl of 1000mgs. I try to take it just before I go to the gym, where I do a little weight training for about a 1/2 hr and about 20 min of carido and then hit the steam rm for about 20 min and then the sauna for about 20 min. If I am lucky I get the flush when I am in the steam rm. I actually like the flush and I don't mind the itchiness. When I am exercising or especially if I am in the steam or sauna I hardly notice it. I have found that if I eat before the Niacin that it almost stops the flush. I just read that eating an apple before taking the Niacin will stop or really limit the flush. Well that's my contribution I hope it helps someone.

I began taking Niatain about two months ago 500mg and experienced mild flushing with no other side effects. Unfortunately my cholesterol went up which surprised me but that included the HDL too. I then was told to start taking 1000mg which I did at night and the side effects remained the same. However, recently I cannot seem to fall asleep or if I do, I only sleep for a few hours and then cannot fall asleep again. I am exhausted and I can only attribute it to the Niatain. I was wondering if I am experiencing the sleeplessness because I am taking one niacin pill during day and one at night. Would it be better to take both at night? I can handle the flushing, but honestly, cannot take this insomnia. Thoughts???

I started out with low dose of niacin each week and worked my way up to 500mg. Taking the adult asprin as directed by my Dr before my dinner and taking the niacin after my meal. I do not seem to have much flushing. He seems to think the regular niacin works better than the flush free type. I am expiercing pain on the left side of my back near my kidney area and muscle's tightening. Will keep an eye on things...

I mistakenly took 2, 500 mg time release niacin. I have been taking niacin for a good 2 years now and once before i got the flushing, throwing up, diarhea, low energy but i was taking that daily. This time, I took it closer in range. (it was a mistake because I had already gotten my vitamins out and didnt realize i had 2 until afterward when checking my vitamin bottle.) i just want to make sure that it will not certainly kill me or do any damage? If I have to, I will forcefully throw them up. The flushing is absolutely unbareable... Hopefully someome can het back sooner than later

Hello All,

I just want to start out saying that I was 290 lbs 3 mouths ago and now I am 260 ounds. I have not eaten differently or anything like that. The only thing I have done was I started talking naicin. I heard about the whole flushing thing and wanted to try it so started out with the no flush 500 mgs and took 8 of them. Felt great afterwards and took them for a month. then I wanted to try the other naicin that causes the flushing just straight naicin no time relaese or anything like that. I have lsot 30 pounds my skin has dramatically improved all over my body I hardly get a pimple. I take about 2 g a day and some days I cleanse my body and take 4 g a day some days I skip a day. My mind state is clearer then ever. I have read naicin is so strong it has help people with mental disorders and it has helped me with depression I am so much happier now. I also started taking Vitamin C with my niacin between 1500 - 2000mgs a day because I read that it helps store the niacin and everyone knows vitamin C is great for the immune system so it's a win win.

I also have an enlarged liver and the days I don't take them is because I get a slight pain in their but I think it's helping it because once the pain goes away it doesn't come back for days whereas I was feeling a little pain there everyday before the naicin. I mean it's cleasing ur body so it should in a sense help ur liver and kidneys.

AVOID THE FLUSH!!!!

It is not difficult to avoid the niacin flush and get up to a useful dose of this very valuable vitamin.

Get 100mg tablets, get a vitamin cutter. Quarter them. Start with 25 mg - 3x - always with meals. If little or no flush, gradually increase. Gradual is the key. Increase by 25mg increments and if excessive flush encountered, back off your dose by 25mg for a meal or two. Then begin increasing again. This will take time to get to 250 or 500 (or more) mg but its worth the effort.

You will likely find, as I did, that if you reduce the dose by 25% or so you can easily take niacin between meals as well with little or no flush.

The first time I took Niacin it was a 750mg dose, lol I had read up on it but had real difficulty believing a vitamin could have such dramatic effect physically, as most vitamin supplements leave you wondering if they are working at all, even months later!...
However *chuckles* 5 mins after taking it I was left in no doubt the flush and everything was very real, the insane itching was the worst! Very strangly I found myself giggling for no reason and couldnt stop! (hilarious for my friend to see)
I've only been taking it for about two weeks and it hardly has any effect on me at all now, sometimes just a bit of a tingle when taken on an empty stomach, so I wonder if it is just working silently, I dont want to take it if it is of no benefit.
I'm using it for depression and as a metabolism booster, I've heard it helps in osteoarthritis (which I have in my hand) and also as high cholesterol runs in the family... so potentially it could have many positive long term effects ... if it still works!

I went to this site because I started taking nicotinic acid and vitamin C My pulse, perhaps by coincidence, increased from 56 yo 90.

People write in to this blog and say that slow release niacin does not affect their triglycerides.

I started taking niacin after reading the EIGHT WEEK CHOLESTEROL CURE bu Robert Kowalski. He says that only the nicotinic acid and not the inositolhexaniconinate form will reduce cholesterol. Almost all of the niacin in the store is inositolhexaniconinate. I told the pharmacist that their niacin is not the form that will reduce cholesterol. I did an Internet search and Wikipedia says the same think.

The few boxes I saw were called "non-flushing and were inositolhexaniconinate, the firm which does not work. I'm no expert, but I think what you want is "slow release niacin" which doesn't cause flushing. It should say "nicotinic acid" on the ingredients.

Hi, from what I've read it it best to use rapid release Niacin opposed to the non-flush. In fact it is highly recommended. And drink plenty of water along with the high doses of Niacin.

Mr. Philo and Others Needing Medical Attention,

If you are not feeling well, always go and see your doctor. If you have blood in your stool, there is an urgent need to see your doctor. In time, doctors will play the primary role helping people find the right doses of vitamin A, B1, niacin, vitamin C, and sunshine, and you will go to your doctor for help with vitamin side effects instead of coming to a blog like this. The goal of this blog is to help that day come sooner.

researched b3 niacin 1000mg for lowering my exceptionaly high cholesterol.after 5 weeks on 1000mg per day it lowered cholesterol by an easy 50%.didnt want statins so looked into the natural way so got b3 niacin & manesium citrate 100mg of which I also took (300mg) per day.i bought the b3 niacin from life extension on amazon & magnesium citrate from holland & barrett.the flush you experience is the veins all over your body increasing in size by 3 times hence your rashes by the way.also spicy foods & alcohol increase your niacin flush so avoid these 2 either side for a couple of hours.also drink lots of water.

One day I slammed two 5 hours and later that night I was drinking. Felt like shit after nausea the hole 9. Didnt think nothing of it. Months later I drink another 5 hour before my trip. I felt the same way I was so sick. Just recently I started a new supplement and felt the same way . Found out it had 20mgs of niacin. Now I cant take that. Is there any way to get my body back normal . I would love to drink 5 hour energy drink again?

At 12:09 AM, Anonymous Anonymous said...

First off, let me be clear. I am a doctor and taking 1000 mg of niacin will never hurt you. All B vitamins are water soluble as is vitamin C. This means that it does NOT harbor in your fat cells. It DOES flush out in your urine when you take more than your body needs.

The reason you flush when taking niacin is because it opens your capillaries and flushes your cells with oxygen.

Niacin, will make you feel alive, give you more energy, and the extra oxygen flow to your cells will allow you to lift more weight if you exercise regularly.

On a side note, niacin will also aid in alcoholism, adhd, and depression. There are numerous studies that have shown 1000 to 3000 mg of niacin has diminished and even stopped alcoholism, and given depressed patients a more positive outlook than prozac.

If anyone criticizes the benefits of B3 (Niacin), then they want to get you hooked on prescription drugs that will give you more side effects than taking a natural substance.

Niacin is the best thing you can do for you body and outlook on life!!!

Good blog Steve, especially in sharing information.

First of all, when it comes to Niacin, I urge people to read the works of the late Dr. Abram Hoffer (who lived to 92 by the way) who was a huge proponent of Niacin.

I personally take 1000 mg a day of a no-flush Niacin. And when I say no-flush Niacin I specifically mean Inositol Hexaniacinate. I've taken as much as 3000 mg a day (3 doses of 1000 mg) in the past but I was hot all the time, an annoyance, but nothing to be afraid of, I just lowered the dose.

I bought Slo Niacin 500mg and used the first dose yesterday. only thing I noticed was loose stools. of course I did eat fresh watermelon and tomatoes from the garden. I am hoping to stop simvastatin 40mg. I use coQ10 as well. I did stop the statin 4 days prior to the slo 500mg niacin. reason I choose to quit statins; forgetfulness, fatigue. many people report this to the sites of statin discussion in seattle times newspaper. shall I -a 64 yr. old female, wt 111 lbs. continue to take slo niacin, vita D and ester C(haven't gotten thiamine yet)? I never ever had any history of high cholesterol until my mother began living with us. my eating became erratic with lot of sugar. my weight did just 10 lbs.being a small person, 10 lbs took me to 111-114 lbs. I try very hard to eat veggies more but my mind wanted sugar. not so much fats, but sugar, and then carbs. I used to exercise all the time and that dwindled due to caring for mom and other household duties. my hubby helps as much as he can-as it was his idea to let her live with us. is stress another factor in high cholesterol ?

I have taken several grams of niacin a day for 40 years and never had a problem after I added a tablet of Pepcid to my dose. Niacin will stimulate the production of acid, and that will get worse with time, resulting in nausea and reflux.

This is a great site and I'm learning a ton about niacin on several lately, one thing niacin does is dilate your vessels to assist in flushing out toxins. Anytime something flushes you out your body will attempt to dilute the effects on your kidneys by releasing more water, so you'll want to drink much more water and keep your pottasium up. Also, almost all B-vitamins and vitamin K will flush the other vitamins out of your system so keep up on those about an hr or two after the niacin and avoid regular menthol use as it dries out the throat and lungs

I agree about the credentials Steve, after all this is a blog where People can share their experiences, not a medical site. However, you may want to be careful about some of the recommendations you have posted because niacin can indeed be dangerous, flushing also wipes out all the other vitamins in your system in addition to toxins and dehydration issues. Also, I recommend you check out the different forms of niacin on healthwyze.com as I saw some recommendations for time release on here (bad?) which may actually be harmful without the benefits at all. All in all, great site and credentials are irrelevant here (I've been studying drugs and herbal medicine for 22yrs and have college level nutrition and TCM and don't have any credentials) but to quote my genius TCM teacher (30+ yrs as dr and surgeon in American and Chinese TCM - EACH!!). "Everything is herb, everything is poison! Only difference is the dosage."

Niacin is good but that is definitely around overdose proportions, everybody please be careful with niacin, that kind of dosage should only be done prescribed with other vitamin supPlements taken After flushing. Most of the "side effects" I have seen on here are likely due to lack of other vitamins or water due to the flushing itself, or toxins from time release or no flush niacin, not true side effects. If you are using this to remove thc from your system people please be responsible and do your research. If its for cholesterol and triglycerides 60-75 mg is usually sufficient and nothing over 500mg twice a day should be neccisary unless prescribed, that might even be too much.

Thanks mrmick I will try the apple trick, I usually take it at the beginning of my meals to minimize flushing and remove extra triglycerides and cholesterol as I had to quit the gemfibrosil statin prescribed because it started to make my back lock up after about 3 mo, also I eat a lot of fast food so I figure at the beginning of my meAl would be most effective, so far it seems to be helping my arteries clear up but fear it is causing me anxiety, as I just had my first attack in about a yr and it may be also causing insomnia, I'm on 75-150mg at this point, will see what happens and post

The nausea normally led to vomiting a dark yellow fluid.

I am 65 and have suffered chronic depression most of my life. I saw a short video with Andrew Saul and immediately dove into the niacin. I have been taking straight full flush 500Mg caps. Way quicker than I should have, I was up to 3Grams/day with no particular flush.

So, following Dr. Hoffers "take it till you puke" (my phrasing :} philosophy theres no telling how much I might end up taking.

The main point is that I feel better emotionally than I can remember. There is no doubt in my mind as to the effect niacin has on depression.

As I said, the ramp up to 3,00Mg was very quick with me adding 1,00Mg a day to the previous dose. 3 days right?

About the same time I hit 3,000Mg I contracted a pretty bad case of contact dermatitis. Although I have never tied down the source of the pollutant, I thing it was being exposed to Alder Tree sawdust. I had blood blotches on my fingers and the skin is still peeling a week later where my fingers were swollen.

I still feel as if I have a bad sunburn+itching all over. I'm going to knock off the niacin for a day or so to see what happens to the body rash and itch.

Have any of you guys had a "whole body" flush that left red skin behind for days? It might be the dermatitis... still trying to figure this out.

Great forum, I've had a good bit of education as well as gotten a laugh or two at the occasional ignorance. I especially liked the person who basically said 500Gm was an overdose. If that's true.... boy am I in trouble.

I believe your problem is the coffee you take in the morning with niacin.

interesting info here--but please be careful in your recommending the time release form of niacin--check you research, this is the form that harms the liver--if continue to get the severe flush with pure niacin, look into your diet--remove allergens, and the flushing not as intense. the flushing is pushing histamine--with less allergens in system, less histamine reaction. Also, the high vitamin C ameliorates the reaction, detoxifying.

Last week i started having diarrhea, which is not typical for me, i am wondering if this is related to Niacin toxicity? 6 days later after decreasing and dropping the niacin i am still have the diarrhea..could the niacin be the cause and how long before it gets out of my system? thanks!

After a great deal of research, I am taking 1500 mg niacin with medical supervision. I take it in the morning only - routine: handful of almonds, baby aspirin, 30 minutes later, the three tablets of niacin. Helps to reduce the flushing discomfort. Greatly.
I am not taking it twice a day as I have heard that it is too hard on the liver to have to process that twice daily rather than once, so there you have it.
Things I can say about it without the benefit of a blood test (cholesteral check) is that I am less lethargic, less inclined to bouts of depressive behaviors, a little more upbeat.

I began taking a non-flush niacin and an immediate acting niacin on Dec 30th. I had a rather intense flush the first day of taking 500 mg of the flush niacin. I turned beet red, was super hot, felt dizzy and when the tingling and heat subsided I was left with chills. It was very unpleasant. On Jan 1 I took another 500 mg dose. This one was so intense that I thought I was going to die and went to the ER. The heat was unbearable. My heart raced to what I counted as 160 bpm and when I was admitted to the ER, I began shaking almost uncontrollably. Once it subsided, after an hour of fluids and benadryl, I was perfectly fine again. Needless to say, it scared me to death and I won't take it ever again. My wife took the same dose without the unpleasant feelings. I wonder why my reaction was so much worse.

I had been taking an over the counter diet pill, where niacin is an ingredient at 30mgs. Three times over the past two week I have had SEVERE hives within 10 minutes of ingesting the pills. Today I made a connection that each time I have had a reaction it was after drinking red wine the night before. Do you think the reaction I had is a simple random niacin reaction or some combination of the wine and niacin? (for the record I am allergic to sulfa drugs, don't think it's related unless it is affected by sulfites in the wine???)

If you read the book "Clear Body, Clear Mind" It will explain Niacin and how to properly use it. Along with the essential vitamin combinations to take with it.

Niacin is a detox vitamin, you flush when you have a deficiency in it. You are actually releasing toxins and radiation from taking it. All good things. Read the book to better understand.

I have been taking Niacin for 6 weeks. Started of at 600 mg for a few days, progressed to 1,5 grams a day. I started feeling extremely nauseous throughout the day, but don't know if it is the Niacin because I have changed my diet and other supplementation drastically last 6 weeks. Last four weeks I started taking 3-7 grams a day, up to 4 grams on an empty stomach in the morning. I now have serious heart palpitations, I can continously hear my heart beat. It has lasted for 3 weeks. I'm really scared now, I'm going off the Niacin from today, hoping it is this that's causing the nausea and palpitations.

Hello!
I am a female aged 32 and started taking Vitamin bs in the hope of regaining my energy. I came here to post this because I believe I am experiencing a delayed niacin flush. I have been taking different forms of vitamin Bs and have had different results- My first flush I experienced a few years back when I started taking only a 50mg dose- this happened within a half hour. I stopped taking niacin for a while after that. Then I tried the liquid- this made me extremely tired so I took it at night. I continued to take it and didn't see any change so I stopped. Recently I have been taking chewables in 50-100mg doses. I started to notice constipation and then got hemmoroids! A FEW DAYS LATER I WAS OUTSIDE ALL DAY- April 18th- and GOT A LITTLE SUNBURNED. I started to get ITCHY!!! very itchy the day after- with my lips and and groin getting very dry the days after that on top of the itchy skin. At first I thought it was an allergy to the outdoors but my sinuses were not affected and my eyes are fine. No stuffy nose or trouble breathing. Oatmeal baths don't work and nothing topical. I have stopped taking the vit bs for a few days now and still have itchy skin....seems to be subsiding. IS THIS POSSIBLE TO HAVE A DELAYED AND EXTENDED NIACIN FLUSH? I can't find info on this anywhere.

I used Niacin a few days before a drug test. I had never taken it before. I grabbed a 500mg bottle from whole foods, not knowing that was such a high dosage. I took one capsule that evening. Took 2 the next morning and another one later that day. I repeated that the next day. Then one last time took 2 capsules. I realize NOW that was way too much. I have since felt a slight uncomfort in my heart area, but no other side effects. Should these pains go away? What should I do to secure my liver and body health?

Hi Steve,

Thank you so much for this post. I'm in my 20's and read a study indicating that taking niacin on an empty stomach significantly increases HGH production in the body. I bought a bottle of 500mg quick release capsules and took one when I woke up. About 10 minutes later, my stomach started hurting and my face felt like it was on fire. I quickly grabbed some food to eat and washed it down with a bottle of water. I searched and found your site, and was relieved to know that the side effects are rather common and I don't need to make myself sick to expel it. I took it about 30 minutes ago now, and my face and extremities are still reddish and tingling, but it's wearing off. My stomach no longer hurts.

I just wanted to thank you for explaining the side effects to me and everyone else who didn't quite know what they were getting into.

When I found out I was HIV-positive, the news sent me into a spiral of shame and self and my man-destruction. will hit rock bottom. I thought I would die from my drug addiction before I died from my HIV. I knew then that I had to take control of my life and get into treatment. After getting clean, I worked with my doctor to find the best treatment for my HIV. I've made taking care of myself and my HIV a top priority. Now, I'm at a point where I can help others get in care, stay on treatment, and learn to live a long, healthy life an my man.an a friend told me that HIV can be cure so this was how, My name is Joy an my man name is White will are for UK.All thanks to Dr.Okwyzil,for his good work and for healing my man and me for HIV sickness he was very sick for three years and my daddy have spend so much money on medical care and drug he have being taking to some many place for healing…This is how my testimony of my self and man on how i came in contact with a real herbalist who helped me. i appreciate everyone for taken their precious time to read my testimony, three years ago i was diagnosed of HIV, this means that three years ago i was HIV positive when i told one of my good friend about this, she sympathized with me and then she said that she was going to help me out, she told me that we should do some research on the internet, we came across Dr.Okwyzil and my friend said that she has come across a lot about him and said that he is a real herbalist remedy to all illness, i was really surprised on this and confused as well, I was so speechless and quickly i contact him to help me and he prepared some herbs for me and send it across to me and he told me the way i was going to be taken the medicine which i did, and in the next 2 weeks i went to the hospital and they said that i am now hiv negative, i am very happy about this, when i contacted Dr.Okwyzil again to tell him the good result , i asked him how he was able to help me, and he said that he was gifted with it that he can cure illness like. email Dr.Okwyzil: dr.okwyilspelltemple@gmail.com or at dr.okwyilspelltemple@hootmail.com dr.okwyilspelltemple@yahoo.com god bless you sir, Whats App +2340951431151

Have been taking 1.5g of instant release niacin for a week.
Here's what I've noticed (39-year-old man):
-sex drive has increased dramatically
-I can easily ejaculate at least 3 times a day whereas previously it was more of a chore.
-more volume in ejaculation through masturbation
-I feel a lot more energy at work and keeping up with my three year old.
-I'm willing to tolerate flushing. In fact, I have been taking it with spicy food because I have a hunch that the flushing may be the cause for all the good things with niacin as opposed to just the vitamin.
-I have a rash that has been itchy due to stress. It's probably do to some kind of histamine response due to stress. But it has improved significantly since taking niacin.

I can tell this isn't placebo. I started taking Niacin because I've been working in a very sedentary job and was worried about LDL/HDL. The energy/sex drive increase was not expected but I've noticed it's happened.

I hope this blog is still going. I know health and lifestyle are big factors in all health related matters so here is a basic overview of my body.

Very Healthy - Young Adult - Work Out almost everyday;Heavy Cardio - Do not smoke or drink more than twice a week. No history of any medical illness; except for asthma as a kid (outgrew it)

On a Sunday, when I got word I would be taking a drug test the following week and had been partying hard the same weekend, I went and grabbed a bottle of Niacin from whole foods. 1 pill was 500mg.

I took 500mg of niacin Sunday night. The next morning I took 2 of those pills in the morning at the same time equaling 1000mg - and later that evening 2 more at the same time. All while drinking cranberry juice and other detoxification liquids. Ya bone headed I know, but wait.. it gets better. I did the same thing for the next 3 days. So I was taking about 2000mg of Niacin for 4 days. Of course I got the flushing and I was expecting it so it didn't bother me all that much, but it still took over my whole body for about 2 hours every time.

After my 4 day niacin phase I completely stopped. I passed the test and everything seemed fine. Then I had some heartburn in the following weeks with some acid reflex but I thought "Well this is expected you completely drowned your system with a foreign substance." The heartburn eased up after a while but still had some acid reflex.

As time progressed I developed a gnawing, constant, everyday uncomfort feeling/pain favoring my left side under my pectoral. At first I thought I had done something real bad and almost life threatening; so I went to the emergency room. They did an EKG and some other tests and found nothing.

The uncomfort/pain is in the same area all the time.

Then I did some research and figured I rubbed my GI tract raw and caused an Ulcer. I got an Endoscopy with a GI specialist that cost about $1000 dolllars and they found absolutely nothing.

Then i factored in I could have some chest pain due to high emotional stress (lots of other things going on in life at this point)

Then I went and saw a Cardiologist and did an EKG and Stress Test. They took pictures of my heart and everything and I was sure they could give me some insight. Well, they found absolutely nothing and said they were even impressed by my stress test.

So here I am, Its 7 months later and I still have a gnawing, constant, everyday uncomfort feeling/pain favoring my left side right around what feels like my left heart area. Its not hindering my life badly (Except for always thinking about it) I just wish I could get an answer, and hope I didnt do anything to harmful in the long run. Any insight what so ever?

Truly amazing story of being cured of HIV... I lost my mother to AIDS in 94 and my father as well i 98 tbey were divorced many yrs. Last night I was researching hollistic methods to detoxing from opioid pain meds and came upon the Center for Health and Well Being headed by Dr. Mestayer in Ca. They treat folks who want to get off alcohol and painkillers with NAD IV therapy protocols. In A nutshell, patients go to the clinic for 8 to 10 days where they are administered by IV Nicotonic acid/Niacin along with Vitamin C and certain amino acids for 8 hrs a day and this protocol helps repair neurotransmitters in the brain to overcome horrible withdrawal syptoms and kick the body in hight gear to repair itself from drug use and alcohol use and everything I read about this seems to be the real deal. There is so much more to this than I care to post but as I understand it this type of therapy is being used for a number of health reasons and felt it was worthy to mention.

Hello, I had a very severe reaction to 150 mg of niacin (not time release) this morning. I immediately began flushing, very, very red over whole body, became weak, felt sick…went to toilet where my vision began to go black around the edges, then I must have blacked out and fell to the ground where I found myself, with no memory of falling, on the floor, very weak, dizzy and unable to get up. With no one there to help me, I made myself as comfortable as possible with towels under my neck, and stayed and rested there on the floor until I could get up. Very dramatic for me, a healthy 74 year old woman. Feel fine again. But don't want to chance niacin again. 50 mg created no problem for me. This was the first time I'd taken 150 mg. Any thoughts?

Hiya Steve. I just replied to someone re: Niacin as Nicotinic Acid. This one works to lower cholesterol. It needs to be immediate release. You don't want the "flush free" as it is the wrong form of Niacin. Immediate release Niacin as Nicotinic acid or slow/extended release supposedly do not cause liver problems. As ridiculous as this sounds, the timed release easily can. Some people get prescription Niaspan which is slow release Niacin. It's also very expensive. If you check out Puritan Pride, the have the right kind of Niacin you want for lowering cholesterol. Item #18645. I don't work for Puritan Pride. I'm just a customer. It was so hard for me to find the correct form if nicotinic acid. All the other types of Niacin I found are all the ones that do not lower cholesterol. Just wanted to make sure you got this and hopefully you do. Hope this helps you and/or someone else.

I stumbled upon this blog by mere chance and am glad I did. i have been researching for months to find a solution to my problem: benzo withdrawal. After switching to diazepam, I have been tapering kinda fast, so I have been taking 3000 mg niacin and 3 g of vitamin C. I am less arthritic now and recently, I was able to exercise a little more. Tapering off benzos is hell, but I'm glad I found out about Dr, Hoffer, Dr. Saul and last but not least, Dr. George Yu and his videos on lipolysis through niacin. I think I am going to increase vitamin C as I think 3 g are not enough. When I first started taking niacin I started out with 500 mg, then I increased it to 1000mg, then 2000 mg and today I took 3000 mg because of the anxiety attack I had. In the beginning I would flush ( it was a pleasant effect for me!) , now I don't flush anymore. I hope I'm not overdoing it, but vitamins never killed anyone as far as I know. I just hope they can work for my problem. Any comments are appreciated.

Came across this article in search of articles regarding Niacin Supplement and pain in the lower back region. My father has been using the flush-free niacin for three weeks, and for the past two weeks has experienced pain in his lower back; kidney area. He said he feels like his kidneys are going to explode. The pain has got increasingly worse, so today he quit taking them and we're going to see if that helps. Do you have any others who've experienced this? I've seen at least two or three comments regarding lower back pain. Any ideas or suggestions? He is currently taking 500mg for breakfast and sometimes 500mg at dinner.

I am wondering if he needs to cut down the dose. Say 250mg for breakfast and 250mg for dinner. I wish he would do the regular niacin, but he doesn't think he can handle the flush.

Does niacin react with L-thianine? I have taken 1000mg niacin for over a month with no flushing. About 30 min before would take 2 aleve 440 mg. Recently I ran out of aleve and had no flushing. I started taking l-thianine 100 mg. To night 4 hrs after taking niacin, I took l-thianine. In few minutes had horrid flushing, like bad sunburn, red skin, and itching. It started with head and went entire length of body. An hour later and still tingling in legs but heat has about gone. I've only notice flushing once before, after out of akeve but was very mild.

I used to take some niacin and enjoyed the flush. I was under methylating at that time, and had some hayfever symptoms, so I quit the niacin. I have been taking vit c, bioflavonoids, and Trimethylglycine, and my histamine reactions are way better. Today I tried a tiny bit of niacin, and passed out, vomited while out. I'm ok now, but realize niacin is really powerful and you have to know what you're doing. Especially if you are prone to high histamine. Good luck folks, and to all you guys who can take niacin with no side effects, well I'm happy for you. All you people on here taking it for drug tests, stop it. And you people with no concept of how your own body works, get educated before you hurt yourself and/or get a good supplement banned. Research. Have a happy day!

While there maybe some side effects (the flush etc) but from what I have heard the benefits of Niacin far outweigh any negatives.

A study I read stated that using Niacin could increase HGH levels by as much as 600%. Now, that is quite a benefit I would say.

Hi, Just started on niacin, only 100 mg. this morning - had a furious flush but I handled it. I eat frozen blueberries every day (also for cholesterol control) in plain yogurt, and I've decided to eat those when I begin the flush.

For Christine, Dr. Rudolph Ballentine wrote in his fabulous book Radical Healing that impurities in the body move out through the skin, too, and it sounds like that could be what's happening to you with your bumps.

Thanks for this blog. I plan to increase my niacin, for concussion and cholesterol. I felt better today after taking it.

My husband fainted while on 4000 mg of this drug. Severe injuries sustained in a car accident. Our Dr. did not believe it was this drug. No one can convince me otherwise. He went off the drug and we had no more incidents. A couple months ago they put him back on 500 mg daily and now 1000 mg. Last night he awoke went to the bathroom and felt nausea. he fainted again. I thought he had a heart attack when I heard him fall. Niacin is dangerous. All his medical work ups come up with nothing. He can take this for awhile with no side effects and then wham...it is done. Never will he take this again as far as I am concerned.

My husband takes this drug. 1000 mg a day. A year ago he took 4000 mg a day. He said he use to have "slow days", he would get nausea and just feel down. One morning he felt nausea, and was out having coffee with friends. He left the diner and got in his truck and fainted with the foot on the gas. Serious injuries. Drs. did all kinds of test and scans. Nothing unusual, I said I thought it was this medicine. Our Dr. doesn't think so. Now he put him on 1000 mg a day. Last night he woke up and went to the bathroom and felt nausea coming on. He turned and fainted. I don't think enough side effects are listed for this medicine. I have always been against him taking it, and now even more so. There has got to be other options to lower tryglicerides.

I take 7 grams of nicotinic acid pure powder between 2 am & noon every day (4 grams between 11 am & noon) with no problems; & only positive mental & body effects. Have been taking gram+ doses every day for 35+ years, after reading about Durk Pearson & Sandy Shaw taking 11 grams every day in 1982. It has never caused me a problem; &, I gather it never caused them a problem. They wrote that they take it for "Psycho-pharmalogical effect" in their book "Life Extension". Cholesterol ratios are outside the "normal range" in the better than normal direction. since it is "better" than Nicotine I would take it even if it was as deadly. Thankfully it has the opposite effects on bodily health.

Lower the dose. Too much Niacin causes Nausea. After being deficient for years, you can take a higher dose of Niacin for a period of time. However, when the body has enough nauseousness occurs. Lowering the dose not eliminating a necessary nutrient is the key. When I checked how much Niacin I needed, 2000 mg made me throw up. 1500 mg. was fine. After a few years of regular consumption, more than 1000 mg is too much.

Also, the timed-released type of niacin is dangerous. I take regular nicotinic acid with equal mg of vitamin C. If niacin is coming from a prescription, it may have other substances (drugs) with it.

Endurance Products sells one type of Niacin (nicotinic acid, not niacinamide) which dissolves in less than an hour. It is called Plain Niacin.

It also sells a Niacin product which dissolves over several hours. This is an extended release product, and therefore has more risk to the liver
.

 
At 4:03 PM, Anonymous Anonymous said...

There are distinct differences between plain or straight nicotinic acid and extended release nicotinic acid. (Most over the counter "niacin" is not nicotinic acid, but rather niacinamide.) Extended release niacin has much higher risks to the liver than does plain or immediate release niacin.

A superb book on this subject is the late William B. Parson's book, Cholesterol Control Without Diet: The Niacin Solution. ISBN 0-9662568-6-7.

I take 3 grams (3,000 milligrams) per day and have done so for about a year,now, using the product he recommends---Plain Niacin by Endurance Products. My blood tests after a month, and again at eleven months were excellent. The "flush" only bothered me the first week of dosage. By the way, Doctor Parsons does not recommend the slow increase in dosage, arguing that the flush is about the same, small or large dosages.

But, be careful. "Niacin" is sometimes niacinamide or hexanicotinate or nicotinic acid. The latter helps control cholesterol; the two former types do not.

The other distinction is immediate release nicotinic acid versus extended release nicotinic acid. The extended release type poses greater threat to the liver. Also, to switch from immediate release to extended release type can be dangerous. A fixed dosage of extended release type is, as I understand it, comparable to twice the amount of immediate release type.

High dose niacin therapy needs to be monitored by regular blood tests and a doctor's expertise

I have been taking Niacin (2000-4000mg) every day for about a year now. Empty stomach or full stomach no problems whatsoever. I enjoy the flush and the mental/ physical benefits have made it a part of my set daily regimen. A couple days ago I ran out to pick up some more but the store was all out, I opted for the "time-released" nicotinic acid version and what a mistake that was. I became extremely sick, blood sugar crashed, terrible nausea and stomach (liver?) pain. 36 hours later and I still feel disabled/ sick.

In short, "time-released" niacin was a terrible experience for me. Research is showing its liver-toxic. The more you know.

Hello Faza. I know this was a long time ago and I am just reading up in the effects of Niacin for myself now. My story is almost identical to yours that you documented on this blog. I'm wondering if it ever got better and if so how ling did it take etc etc. Any info or feedback would be helpful at this point. Thanks and hope that you're well.

Hi,
I would like your advice or comment if you have experienced this. I'm sorry this is so long winded but It's a problem.
My entry for 9th Feb. 2017
includes, " Threw up 5 times last night."
This all stemmed from the evening of the eighth where just after dinner I took 9 grams
of Nicotinic Acid. This is a lot but was trying it to treat a mental disturbance, based on Dr. Abram Hoffer's recommendations. For a week or so previously, I had just been taking the niacin. Knowing I needed to have all the B vitamins, I also took B complex. Bad mistake. This resulted in the vomiting I have mentioned. At this stage I stopped taking all supplementation.
I was able to swallow water. On the 10th I also managed a few grapes. On the 11th I tried some fruit smoothie and had a few sips but pain in swallowing. Then I had a throat spasm. After that for the rest of the day I had to hold my hands to my throat to swallow saliva and was harder to take water sips. Also a dry cough started around this time.
Then I decided to fast on water completely and within a day or so swallowing water/ saliva gave no pain. I have just finished a 40 day fast..yesterday, in fact. The suprising thing is that the dry cough has remained. I have always been a firm fasting believer, but it seems the throat still has damage. Other things are better; not that I was ill beforehand. I have also had, through the fast, blocked up ears and often sound congested. When I cough I bring up fine bubbled, white and frothy mucous. Another thing that has been there all through, is the feeling that I have hairs or fibres stuck in my throat. Today I broke the fast on half water, half diluted fresh juice.It was mandarin. I found at first fine but then irritating my throat, making me cough and bring up this mucousy phlegm.
Has anyone had this experience or similar?

Hello. I just found your board. About a month ago I started taking Niacin for high cholesterol and was interested in why some take vit. C with it? Also, for the last 5 days, I have been having extreme muscle pain between my shoulder blades and into my neck. Has anyone had issues with muscle pain in the upper back while taking these supplements?

I think the hand thing is coincidence. They sound like flat warts. Ive had them on my index finger for 8 years and recently found out what they were. They are difficult to remove but only spread to the back of the hands, face, and legs. Mine flare up and look worse and redeer sometimes too? I couldn't tell you why, but I recommend a dermatologist. Take care!

Hi there, I thought taking a B3 supplement would help me avoid a miscarriage, thanks to some recent medical research findings in Australia, so I asked for a Niacin supplement at my local health food store. I was advised to take 1000 mg and I did see a warning about flushing but was told that this wouldn't happen as long as I took this after food.

So I took one pill after I ate a piece of toast but I still had the most horrific reaction which was terrifying at the time.

Within minutes of taking it, my face and body turned red and I broke out into a prickly heat rash, my eyesight started going blurry, I started shaking uncontrollably and then had intense labour-like abdominal cramps and diarrhea. It lasted for over an hour and I thought my husband was going to have to take me to the hospital. Even though this passed, I was still red, hot and shaken hours after taking just one of these pills.

There should be warning labels on the pack, and people behind health food counter shops shouldn't be selling 1000 mg to people who haven't built this product up in the body by starting on much smaller doses, and working their way to this strength over time. Further to this, I don't have a cholesterol issue, so it shouldn't have been sold to me at all.

I bought 1000 mg of b3 (niacin) thinking it would be a safe and gentle supplement but within minutes of taking it, I had a severe reaction - my face and body turned red and I broke out into a prickly heat rash, my eyesight started going blurry, I started shaking uncontrollably, and then had intense labour-like abdominal cramps and diarrhea. It lasted for over an hour and I thought my husband was going to have to take me to the hospital. Even though this passed, I was still red, hot and shaken hours after taking just one of these pills.

There should be warning labels on the pack, and people behind health food counter shops shouldn't be selling 1000 mg to people who haven't built this product up in the body by starting on much smaller doses. Further to this, I don't have any issues with cholesterol.

I asked for this product as research findings in Australia have proven that a niacin supplement can help women trying to get pregnant decrease their chances of miscarriage.
