Riboflavin ranks among the most critical of the B-complex group. It’s the catalyst for the metabolism of carbohydrates, healthy fats, and proteins for generation of energy within cells throughout the body. B2 is also essential for tissue formation including skin, hair, and nails. Its synergistic action with other B vitamins, amino acids, and hormones makes the identification of a shortage of B2 and subsequent supplementation a must for ongoing health and wellbeing.
