Product overview
Riboflavin, also known as vitamin B2, is necessary for the body to be able to activate vitamin B6. Riboflavin is also necessary for the body's conversion of tryptophan to niacin, and the conversion of folate to folate's various active forms. In addition, riboflavin plays a crucial role in the metabolism of fats and glucose, the synthesis of red blood cells, healthy methylation, and the production and regulation of certain hormones. 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.
