Niacinamide, also known as vitamin B-3, functions in over 50 metabolic reactions throughout your body, 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 formulated to provide a gradual release over a prolonged period of time.

Rated 3 out of 5 by from Be aware: Huge tablets If you have problems with giant tablets, I wouldn't recommend these 1,500 mg niacinamide. They are 7/8" long, 3/8" wide, 1/4" high. Source Naturals is a good brand, but I think I will return to a smaller tablet twice per day.

Rated 5 out of 5 by from Easiest way to take 1500 mg. I have been using niacinamide for several years for my memory and I was so happy to find a time release formula in the dosage I take. The price is great too, especially when I can get a sale which Swanson has often.

Rated 5 out of 5 by from Time and Again It is really great to have this in timed release. Sometimes B complex can be uncomfortable when in a at one dose.

Rated 5 out of 5 by from I feel an improvement Since learning about Niacin from watching Food Matters and a few other documentaries on Netflix, I decided to give this a try, and I have to say I have seen an immense improvement in my well-being and emotions. Highly recommended!
