Riboflavin (also known as vitamin B2) is one of the B vitamins, which are all water soluble. Riboflavin is naturally present in some foods, added to some food products, and available as a dietary supplement.
This vitamin is an essential component of two major coenzymes which play major roles in energy production; cellular function, growth, and development; and metabolism of fats, drugs, and steroids. The conversion of the amino acid tryptophan to niacin and the conversion of vitamin B6 to the coenzyme pyridoxal. In addition, riboflavin helps maintain normal levels of homocysteine, an amino acid in the blood.
