Vitamin B-3 (niacin) by Life Extension - Side-Effects, Benefits, Vitamins, Deficiency - Dose

Many B vitamins are used in the body individually or in combination with enzymes to help release energy from carbohydrates, fat, and protein. Vitamin B coenzymes are crucial to the metabolic pathways that generate the energy needed by every cell in the body. Because they are codependent in their metabolic activities, a deficiency of one B vitamin can affect optimal functioning of organ systems throughout the body.

Niacin is the only B vitamin that can be synthesized in the body from the amino acid tryptophan.180-183  In its coenzyme forms, niacin is crucial to energy transfer reactions, particularly the metabolism of glucose, fat, and alcohol.184,185  Niacin's beneficial effects on blood lipids is well documented.186-201

Caution: Niacin, in doses of one to three grams per day, is one of the safest and most effective substances to support healthy cholesterol levels.  Niacin releases histamine and causes capillary dilation, which may cause a harmless flushing of the skin.  This effect can be lessened by taking the niacin after eating or by starting with a low dose of 50 to100 mg.  Then, as tolerance develops, you may begin increasing it progressively.

Recommended dosage:  1 capsule per day.
