Advanced Info Vitamin B2, also known as riboflavin, is a water-soluble vitamin that is necessary for normal growth and maintenance of health as it functions as a coenzyme in energy metabolism. Riboflavin is also necessary for red blood cell formation, antibody production, cell respiration and growth, and works as an antioxidant to track down and destroy free radicals in the body. Riboflavin functions in the metabolism of proteins, fats, and carbohydrates, enabling the body to release energy from these nutrients and making them available to tissue cells. It also supports healthy vision and helps maintain healthy skin. As riboflavin is not stored in the body, it must be added in the diet daily either through food sources or through supplementation. Unfortunately, vitamin B2 is not available in a wide variety of foods nor is it present in large quantities in foods, so a deficiency is common in those who have unbalanced diets. Natural Factors Vitamin B2 contains 100 mg of riboflavin per tablet to help in the maintenance of good health and especially in the metabolism of proteins, fats, and carbohydrates.
