Niacin (vitamin B3) is one of the central vitamins in human energy metabolism. The body uses niacin to form the coenzymes NAD⁺ and NADH, which are involved in energy production in virtually every cell. Without sufficient NAD⁺, mitochondria cannot efficiently convert nutrients into energy.
Bill W., co-founder of Alcoholics Anonymous, already recognized that niacin can play a surprisingly important role after meeting Canadian psychiatrist Abram Hoffer.
