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.

Give you the "flush"!

Posted by 4858815334864707048 on Dec 27, 2016

I guess it works, it gives you the flush. I understand this lowers cholesterol naturally. Not that cholesterol being high is bad, that's a myth perpetuated by main stream heath care. Google Dr. Stephanie Seneff - she has great talks on youtube all about that. Niacin is also supposed to be good for fighting depression. I don't take Niacin regularly, just thought I would see what the flush is - and take it if I ever I see the need in the future based on the interesting things I have found about it in my research.

Very pure

Pure niacin. I like the "flush" effect. I am not sure about the benefits because I have been taking it relatively short time.

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
