R2-B2: the vitamin you are looking for

Why we need it

  • Riboflavin, also known as vitamin B2, is an antioxidant that protects cells against free radical damage that may contribute to elevated rates of heart disease and cancer1*
  • Converts vitamin B6 and folate into their bioavailable forms to maximize absorption*
  • Important for growth and red blood cell production2*

Why we include it

The B complex vitamins help the body convert food into energy in the form of glucose and utilize fats and proteins. They are essential for a healthy nervous system and healthy skin, eyes, and hair. Although a riboflavin deficiency is rare in the U.S., it’s such an important vitamin that we’ve included it in our Women’s and Men’s Complete multivitamins to ensure you’re getting adequate levels of this nutrient. Since all B complex vitamins are water-soluble, your body will simply eliminate any it doesn’t use.
