Vitamin B2, also known as riboflavin, helps your body turn the food you eat into usable energy and also acts as an antioxidant. It contributes to normal energy-yielding metabolism, the maintenance of normal skin and vision, the normal function of the nervous system, and the reduction of tiredness and fatigue.

Riboflavin is water-soluble, so your body doesn't store it and any excess is passed out – which is why a steady daily intake matters. It's found in a wide range of everyday foods, including fish, meat, eggs, milk, mushrooms, fortified cereals and almonds, so deficiency is quite rare. That said, some people can find it harder to get enough, and a supplement can be a simple way to keep your daily intake steady.
