Niacin Flush

Introduction

Niacin is a truly crucial vitamin for human health. Niacin is contained in all the cells of the body and is stored in the liver. It is an important building block for the so called coenzymes. Without this vitamin, it is impossible for your body to have a good metabolism. The importance of niacin has been emphasized by several health magazines and other experts. This resulted in hype and people became anxious to eat as much niacin rich food as they could. The purpose of this article, therefore, is to describe niacin rich foods you should consume or avoid, what is the appropriate dose, and what you can do against
niacin flush.


Niacin rich foods

Natural sources of vitamin B3 are protein rich foods like:

  • Chicken
  • Fish (Tuna and Salmon)
  • Mushrooms
  • Dairy
  • Eggs

Other products that contain niacin are:

  • Liver
  • Coffee
  • Whole grain products
  • Asparagus
  • Halibut
  • Venison

You might wonder what you have to eat if you are a vegetarian. Well, the following foods have been recommended for those people: peanuts, grains, dates, champignons, yeast and dried apricots.

Dose

The appropriate dose differs per sex.  For women, 15 mg per day will suffice. Men will need a little more: 20 mg per day. In order to help you estimate what you have to eat on a daily basis, I have made the following list of best niacin foods and how much you should eat of them.

1. Raw Crimini mushrooms (5 OZ-wt). These mushrooms contain 5.40 mg niacin.
2. Shiitake mushrooms (1 cup). These inhibit 5.50 mg niacin.
3. Tuna (4 OZ-wt). Tuna has a dose of 14.60 mg niacin.
4. Tamari (1 tabs).  This soy sauce has 0.8 mg niacin.
5. Chicken breast (4 OZ-wt). This equals 14.40 mg niacin.

However, it has to be noted that there are many more good sources of niacin. The key is to have some variation on a day to day basis. You do not want to eat Shiitake mushrooms every day, unless it is your favorite dish or something. Another handy tip I can give you is noting every niacin rich meal down in a notepad. In this way, you can easy see how much vitamin B3, you already have consumed and you are not very likely to severely overdose.

An overdose of vitamin B3 can cause: diarrhea, dysfunctional liver, a too high blood sugar level and gout.  First of all, it is not a good idea to mix vitamin B3 rich foods with niacin supplements. Take one or the other, not both.  If you have taken too much niacin without knowing it, it might help to take some vitamin C and consume some garlic. Also be sure to drink a lot of water and go to the toilet often.  Besides this, there is not much else you can do, if you have already consumed the overdose. Prevention is better than cure, and this is certainly the case for niacin overdoses.

If you have a severe overdose, it is recommended to immediately seek medical assistance. General practitioners may put a tube in the stomach to get rid of the superfluous niacin.  Fortunately, niacin overdose will rarely lead to death.  Nonetheless, it can lead to some very uncomfortable and anxious feelings. Vitamin B3 becomes toxic when you exceed amounts of 200,000 mg, which is almost impossible with natural food. As long as you follow the advice of the food tables you will be fine. Even better is to record everything and calculate on a day to day basis how much niacin you have consumed.

    I eat anything with niacin and scratch and scratch. It hurts really bad and doesn’t stop unless I take a benedril. then it can take an hour to quit. I can’t take asprin. If anyone has an answer please help. I feel I must be highly allergic to niacin, because it takes barely any to cause the itching reaction.

      I actually for the first time took 4 tablets called Eyemax Plus for the cure of cataracks…..which contains a mixture of 30 vitamins minerals and antioxidants…..
      Included is 50mg of NIACIN….For the first time I took 4 tablets which should have been 2 am and 2 pm (my error) and had a breakfast of 1 large mushroom (which I just found out contains NIACIN) with 1 egg and 1 breakfast sausage…..3 minutes after my breakfast….I felt a burning sensation and it started to move from under my chin upwards….swelling and so red and itchy….I panicked and stood under the fan to cool off but realised it did nothing….then I got a wet facewasher and covered my face but still the burning sensation…..My husband then raced me to the Dr who is just up the road……By this time it was spreading to my arms……She immediately gave me a PHERNEGAN injection and I stayed in the surgery until I felt sleepy and my daughter helped me out…..My doctor thought I was alergic to the bilberry also included………she then gave me a prescription for ZYRTEC to take. I did not touch the Eyemax Plus for a week as I was not sure whether it was the mushroom or the tablets…..I then tried the Eyemax Plus again taking 2 tablets….Immediately the redness and puffiness and burning and itch started to creep up my face….I again rushed back to the Dr but took a ZERC tablet first…..By the time I got into see her, the redness and burning was slowling disappearing…..She told me not to take the tablets again and that I did not need an injection as the ZYRTEC tablets did the job. Now I just googled NIACIN FLUSH and discovered that it was the NIACIN which caused my flush and that it was ok so I am going to take my Eyemax tablets and know I am safe…..

    Dear Peggy,

    The side effects are very intense for most people,
    especially for women since their recommended dose is lower.
    I recommend to keep the overdose low, and to endure the pain.
    There is no way around this, unfortunately.
    However, I would talk with your general practitioner about this subject first.

    I recently developed a allergy to niacin. It took me the longest time to figure out why I would flush and get all tingly after eating what I thought were my normal meals (baked potato, eggs, etc) But one different thing I had recently started was a multi vitimin with niacin in it. I was googling my symtoms and came accross a niacin flush article. I find that I am fine when I dont take a multi vitamin with niacin in it, so now I am looking to see if they make a multi vitamin without it. This has been a strange journey for me to find out what was causing these flushing symptoms, but I am feeling better knowing what it is and what foods are rich in it to avoid the symptoms. Thanks for your website information.

    I have been making mushroom burgers everyday. I have recently started having heart palpitations. The doctors have not been able to find anything. I have taken niacin in the past and got that burning warm sensation. I think this mushroom binge is the root of the heart palpitations. So no more mushroom burgers for a bit. I’ll see how my body responds.

  • BZ:

    I’m on a 2000 mg per day prescription for niacin (for cholesterol) — if I don’t eat first, the flushing and itching lasts about 1/2 to 1 hour. Sometimes I’ll take aspiring to alleviate the discomfort. Otherwise it’s fine.

  • Hilda Flores:
