While producing energy Riboflavin converts to flavin adenine dinucleotide (FAD) or flavin mononucleotide (FMN). After converted to these form, Riboflavin can attach to protein enzymes and allow oxygen-based energy production to occur.
  •  Riboflavin strengthens the immune system and maintains healthy digestive tracts. It also promotes the immunity and protects the body from infections and diseases. Inadequate amount of Riboflavin in the body increases the levels of homocysteine. High levels of homocysteine increases the risk of heart attack, damages blood vessels and raises blood clotting.
