Product Overview


  • Dietary Supplement

Niacin is necessary for protein metabolism, energy production and normal nervous system function. It may also help regulate blood sugar, cholesterol levels and is required for the production of the adrenal and sex hormones. Niacin has a strong effect on the circulatory system causing some people to experience flushing, a sensation of heat and reddening. With today's lifestyle, it is often difficult to get proper nutrition, making Natural Factors Niacin tablets your nutritional insurance to fortify your daily diet.

All Natural Factors products are manufactured in accordance with the Government of Canada's Good Manufacturing Practices (GMP), among the highest standards in the world.

I had an allergy as soon as I had one tablet. Thank God I know my body and quickly took a shower and apply coconut oil all over my body!

The real deal

Posted by Reviewer2682516 on May 03, 2016

This Niacin is what I expected incl. the flushing.But when you eat something at forehand you don't have the flush.I take the tablets after each meal.That makes a total of 300 mg. I take it in combination with B complex and L-Glutamine powder. 2,5 month no alcohol graving any more and my cholesterol is much better. Al I can say: Give it a try!

to get a good flush

Posted by DrHASANAH on Dec 29, 2015

I don't know what's the advantage in getting a flush...with this product, to get a major flush, take it with hot coffee..and to avoid flush, take it with cold water and food

Good product

Posted by Reviewer1356683 on Sep 22, 2015

I use it happily as a sublingual since I have gastritis. Excellent that it has only cellulose added, like that I enjoy taking it every day. I will be reordering since it has become an important part of my daily routine. My husband wanted to take it only every second day but he enjoys it so much that he has been taking it every day.
