Vitamin B-3 Facts
Vitamin B-3 (Niacin) is a water soluable vitamin, meaning any excess is excreted and not stored in the body. If a person is not deficient in Vitamin B-1, B-2, and B-6, the body can manufacture its own niacin using the amino acid tryptophan, although it takes 60 mgs of tryptophan to yield 1 mg of niacin. About half of the niacin found in a diet comes from this processing of tryptophan, from food sources of eggs, milk and poultry. Niacin is good for lowering cholesterol and may be instrumental in the prevention and treatment of depression, arthritis, and other ailments.
