Riboflavin

Riboflavin, also known as vitamin B2, is a vitamin found in food and used as a dietary supplement. It is required by the body for cellular respiration. Food sources include eggs, green vegetables, milk and other dairy product, meat, mushrooms, and almonds. Some countries require its addition to grains.

As a supplement it is used to prevent and treat riboflavin deficiency. At amounts far in excess of what is needed to meet dietary needs as a nutrient, riboflavin may prevent migraines. Riboflavin may be given by mouth or injection. It is nearly always well tolerated. Normal doses are safe during pregnancy.

Riboflavin was discovered in 1920, isolated in 1933, and first made in 1935. It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system. Riboflavin is available as a generic medication and over the counter.
