Swanson R-5-P (Riboflavin-5-Phosphate) - Vitamin B2 Supplement Promoting Energy, Metabolism & Vision Health - Natural - (60 Capsules)

Like many other B-Complex Vitamins, riboflavin must be converted into its active form to be utilized by your cells, hence the importance of riboflavin 5'-phosphate supplements. In the human body, this process takes place in the cellular mitochondria when dietary riboflavin is converted by the enzyme riboflavin kinase into riboflavin 5'-phosphate (r5p), which is the principal form of riboflavin found in cells and tissues. Swanson ultra r-5-p lets your body sidestep this process by delivering the Vitamin directly in its active form so it's ready to perform its vital functions in cellular energy metabolism.
