Vitamin B2 (riboflavin) is one of the eight B vitamins. It is a water-soluble vitamin and not stored in the body. It is formed by gut bacteria but not in sufficient amounts. Rich sources of vitamin B2 include meat, milk, eggs, nuts, fortified foods, and green vegetables.

Riboflavin is involved in various body processes. It is involved in the metabolism of folate, vitamin B6, vitamin B12, and other vitamins. It helps maintain healthy skin, the lining of the digestive tract, blood cells, and brain function. It is required for the production of antioxidant glutathione in the blood.

The deficiency of vitamin B2 is often associated with other deficiencies and is rarely a standalone issue. Its deficiency increases oxidative stress in the body causing various skin problems. Riboflavin is mostly prescribed as a part of vitamin B - complex supplement in case of deficiency. Other uses of riboflavin include migraine and high homocysteine levels in the blood
