Riboflavin 5′-Phosphate

To be utilized by the body, however, riboflavin must first be converted to its active form – riboflavin 5′-phospate (R5P). A compromised digestive system, however, can adversely affect the body’s ability to convert riboflavin to R5P. And certain prescription medications can also compromise the absorption of riboflavin, putting it in a state of deficiency. Thorne’s Riboflavin 5′-Phosphate, which is not derived from yeast, provides supplementation with a bioactive, tissue ready form of riboflavin that can be optimally utilized in the body.
