Vitamin B2, also called riboflavin, is one of 8 B vitamins. All B vitamins help the body to convert food (carbohydrates) into fuel (glucose), which is used to produce energy. These B vitamins, often referred to as B-complex vitamins, also help the body metabolize fats and protein. B complex vitamins are necessary for a healthy liver, skin, hair, and eyes. They also help the nervous system function properly.
All B vitamins are water soluble, meaning the body does not store them.
In addition to producing energy for the body, riboflavin works as an antioxidant, fighting damaging particles in the body known as free radicals. Free radicals can damage cells and DNA, and may contribute to the aging process, as well as the development of a number of health conditions, such as heart disease and cancer. Antioxidants, such as riboflavin, can fight free radicals and may reduce or help prevent some of the damage they cause.
