Supports energy production

Formula re: Contains

Vitamin B-2, also known as riboflavin, is a component of two enzymes: flavin mononucleotide (FMN), and flavin adenine dinucleotide (FAD). These enzymes are important in energy production, and are essential for normal fatty acid and amino acid synthesis. Because of their vital roles, cellular growth cannot take place in the absence of vitamin B-2 riboflavin.
