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.


How does Niacin (vitamin B3) support health?

  • Promotes healthy lipid metabolism.*

This is a wonderful product and its a great price here.... December 26, 2014
Great Product Comparing this to all the other products available, I've found the Vitacost product works the best and is the best value by far. February 24, 2014
Consistent quality The only thing better would be if they brought back the 1,000 mg version they used to offer. Every product I've purchased over the years from Vitacost has been of high quality. Add to that very competitive pricing and you have a winning combination. November 5, 2013
