Product Overview


  • Vitamin Supplement

Niacinamide, also known as vitamin B-3, functions in over 50 metabolic reactions, most of which are enzymatic. Its bioactive forms - NAD+, NADH, NADP, and NADPH - play important roles as catalysts in the energy production process in the cells, the breakdown of proteins and fatty acids, the synthesis of fatty acids, and the formation of steroid hormones and red blood cells. Source Naturals Niacinamide is prepared to provide a gradual release over a prolonged period of time.

High dosage means fewer pills to take!

Posted by iHerb Customer on Feb 27, 2017 | Verified Purchase

My husband takes this for brain function because he has Alzheimer's disease. He takes 2 each day. It seems to be doing a good job of helping him stay better for longer so I'm quite pleased with it He doesn't like the taste of it, though. He found the capsules that he was taking previously easier to take. But this brand is good because each tablet is quite a high dose so he doesn't need to take so many of them.

Thanks for your feedback!
