Vitamin B2 

Vitamin B2 is vital for energy metabolism, tissue formation, red blood cell and hormone synthesis, and to help maintain normal glucose and lipid (fat) metabolism. It's also needed to activate other B vitamins, including folate and vitamin B6, and to convert tryptophan to niacin (vitamin B3).

This unique biocoenzymated formula combines Farm Fresh Factors, an organic whole food blend of land and sea vegetables, with the coenzyme form of vitamin B2. The result is a synergistic phytochemical formula that delivers the most metabolically active nutrients to your cells. Ready-to-use R5P offers immediate and direct nutritional support.
