Vitacost Niacin (Vitamin B-3) Description

Supports healthy lipid metabolism and circulation!*

What is Niacin (Vitamin B3)?

Niacin (vitamin B-3) also known as nicotinic acid, is a member of the B family of vitamins and is found in the company of other B vitamins—vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B12 (cyanocabalamin) and folic acid.


Niacin is water soluble, meaning it’s not stored in the body and must be replaced daily. It can be found in many foods, including meat, fish, milk, eggs, green vegetables, cereal grains and yeast. The amino acid tryptophan, present in protein-rich foods like red meat, poultry, turkey, dairy products and eggs, can also be converted to niacin.

Niacin is important for many biological functions. It plays a role in carbohydrate, fat and protein utilization. In its coenzyme forms, niacin is crucial to energy transfer reactions related to fat, alcohol and glucose.*


Niacin acts as a vasodilator, and the flushing and tingling sensation it creates is often mistaken for an allergic reaction. Flushing can occur when using large or even small doses of niacin. Symptoms of a mild deficiency of niacin include fatigue and indigestion. Pellegra has been long understood to be a form of a niacin deficiency.

  • Promotes healthy lipid metabolism.*

Sad they dc'd 1000mg caps I've been buying this full flush Niacin for years. Last time I checked the literature, there was an indication that benefits from flush niacin were better than flush-free. Also there was an indication of unwanted and potentially unhealthy effects from large dosages necessary of the flush free - all that extra effort and marketing to avoid the flush - when in fact the effect dissipates the longer it is taken. It's my understanding that the European medical community utilize regular niacin and not the flush-free. I'm just sayin' - - - June 14, 2013
Great buy Very pleased with the product, service and pricing. March 6, 2011
Best flush fot the $ I've used this product before and it is a great buy. Sometimes I flush and sometimes I don't. But I find the same is true for the LEF products and they are many times the price of this. Seems if I want to flush I take this on an empyt stomach and on a full tummy if I don't. December 6, 2009
Great Value Since sustained-release niacin is not recommended due to liver problems, this is the only other option besides going Rx with Niaspan(Extended Release) which is very expensive. If you can tolerate the 'flush', as I, this is a great choice. Very economical too. July 15, 2009
Niacin didn't work I have now been taking niacin daily for a couple years. When I take niacin I want to feel the skin flushing that comes with it so I get the regular niacin that causes flushing as opposed to the slow release variety. With this niacin I felt no flushing while taking 1000 mg, so I have to think that something is wrong. I purchased the 1000 mg capsule size here before and it worked fine. This just did not work. Don't know why but I tried another brand at the same time and it worked fine, so I know my body is not now immune to flushing. I can only conclude that something is wrong with this batch.
