B3 - Niacin

Vitamin B3 for antioxidation and energy production

Niacin, or vitamin B3, is a water-soluble B vitamin found naturally in some foods, added to foods, and sold as a supplement. The two most common forms of niacin in food and supplements are nicotinic acid and nicotinamide. The body can also convert tryptophan - an amino acid - into nicotinamide. Niacin is water-soluble so that excess amounts that the body does not need are excreted in the urine. Niacin functions in the body as a coenzyme, with more than 400 enzymes depending on it for various reactions. Niacin helps convert nutrients into energy, build cholesterol and fats, build and repair DNA, and act as an antioxidant.
