vitamin B2

Quick Reference

(riboflavin) a vitamin of the B complex that is a constituent of the coenzymes FAD (flavine adenine dinucleotide) and FMN (flavine mononucleotide). Riboflavin is therefore important in tissue respiration. A deficiency of riboflavin causes a condition known as ariboflavinosis, which is not usually serious. Good sources of riboflavin are liver, milk, and eggs. The recommended daily intake for an adult is 1.3–1.6 mg.
