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.

Vitamin B3 is part of the coenzyme composition and over 200 enzymes need these catalysts. These enzymes are involved in the degradation of carbohydrates, lipids, proteins and alcohol and in the synthesis of macromolecules (fatty acids, cholesterol, etc.). In laboratory tests, vitamin b3 plays a role in protecting the DNA and can reduce the risk of cancer. Vitamin B3 in food does not produce adverse effects, but supplementation can cause itching, gastrointestinal disorders, vomiting, nausea, hepatotoxicity, hepatitis (very high doses 3-9 g, long-term), skin redness, dry skin, etc. Most side effects were seen with immediate-release supplements. It seems that when taken at doses much higher than those recommended by the authorities, vitamin B3 is able to strongly stimulate the immune system to the point where many diseases can not survive. According to many studies, vitamin B3 is capable of increasing the capacity of the immune system 1000 times, allowing the body to naturally fight with dangerous pathogens. And unlike antibiotics, vitamin B3 does not destroy all the beneficial flora of the stomach along with the dangerous bacteria. So for many people, taking a high dose of vitamin B3 would be better than taking antibiotics that might often make you more harm than good. The evidence is that drug companies use it under a similar name and invoice it at a much higher price. They claim that their product has no side effects. Of course, when it is niacinamide. The product is good, with no visible side effects. It does not produce hot flashes, and timed release provides a gradual release over a prolonged period of time compared to regular release products. The pills are large, but it's normal for the dose. They can still swallow lightly because their edges are rounded.

Thanks for your feedback!

Niacinamide is very helpful in reducing anxiety

Posted by iHerb Customer on November 22 2017 | Verified Purchase

I find this product is really effective in reducing anxiety and the physical effects it has on the body. I've been told by health professionals however, that it's important not to take a sing;e b vitamin in isolation for extended periods without taking a to multi-b vitamin as well.

Thanks for your feedback!
