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, support methylation, and the production of certain hormones.

To be utilized by the body, however, riboflavin must first be converted to its active form – riboflavin 5'-phospate (R5P). Thorne's Riboflavin 5'-Phosphate, provides supplementation with a bioactive, tissue ready form of riboflavin that can be optimally utilized in the body.

Can't live without it

I take this three times a day at the recommendation of my neurologist and it significantly helps some of my fatigue and fibromyalgia symptoms. An absolute lifesaver, I'm so grateful.
