Vitamin B2 is important for the production of energy in the electron transport chain. It acts as antioxidant protection as it is one of the many nutrients required to recycle glutathione. It also promotes iron metabolism, improves muscle cramps, boosts the immune system, slows aging, helps maintain healthy skin and hair, treats canker sores and improves memory loss, for example in cases of Alzheimer’s disease. It is also highly recommended to prevent eye problems, such as cataracts, glaucoma or keratometa, which develop with age.
