Vitamin B2, also known as Riboflavin and formerly vitamin G, is part of the B vitamin family, and as such it is water-soluble and not stored by the body. This makes it important to monitor for any deficiency. All plant and animal cells contain Vitamin B2, but there are very few rich sources.
Vitamin B2 contributes to the maintenance of normal skin, the normal functioning of the nervous system and the reduction of tiredness and fatigue.
Vitamin B2 also contributes to normal energy-yielding metabolism as it helps the body release energy from food (fat, carbohydrates and protein).
Moreover, Vitamin B2 contributes to the protection of cells from oxidative stress as it assists several antioxidant enzymes (protection of DNA, proteins and lipids from oxidative damage).
