Vitamin B2 (Riboflavin)

Riboflavin is yet again another B vitamin that plays an important role in energy metabolism and the conversion of food into fuel. It also protects our cell membranes from oxidative damage and safeguards our eyes, skin, and blood vessels. B2 works as an antioxidant and helps to fight free radicals.

Riboflavin is important for healthy vision and studies have shown promise for riboflavin’s use in the treatment of age-related cataracts [II]. Those who suffer from migraines might also find benefit from Vitamin B2, as it has been shown to reduce the severity and duration of them [I].
