Riboflavin, also known as vitamin B2, is a water-soluble vitamin that plays a crucial role in energy production and the metabolism of fats, drugs, and steroids. It is essential for the maintenance of healthy skin, eyes, and nerve functions. Riboflavin acts as a coenzyme in various biochemical reactions, particularly those involving the conversion of carbohydrates, fats, and proteins into energy. It can be found in foods such as eggs, dairy products, green leafy vegetables, and fortified cereals.
