Overview

Vitamin B2, also known as riboflavin, is an essential water-soluble vitamin that plays a crucial role in maintaining human health. As a component of two major coenzymes, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), riboflavin is integral to a wide array of cellular processes, including energy production and metabolism of fats, carbohydrates, and proteins. It is also required for the proper function of other B vitamins, such as the conversion of B6 to its active form and the conversion of tryptophan to niacin (Vitamin B3). Riboflavin contributes to the maintenance of healthy skin, eyes, nerves, and red blood cells. Since it is water-soluble, the body does not store large amounts of riboflavin, and any excess is typically excreted in the urine, giving it a characteristic yellow-orange color. Therefore, a consistent dietary intake or supplementation is necessary. Riboflavin is naturally present in several foods, including milk, cheese, eggs, leafy green vegetables, lean meats, and fortified cereals (NIH Office of Dietary Supplements).
