What it is
Vitamin B2, also called Riboflavin, is a water-soluble vitamin that is essential for energy production, cell function, and metabolism. It occurs naturally in foods like eggs, meat, dairy products, and green vegetables. It can also be produced synthetically for use as a food additive.
Why it's used
Riboflavin is added to foods as a nutrient supplement to fortify them and improve their nutritional value. It is commonly found in enriched grain products like bread and cereals, as well as dairy products and infant formulas. It also acts as a yellow coloring agent in some foods.
Health notes
Riboflavin is recognized as safe and effective by the FDA when used as a nutrient supplement. The US National Academies have established a tolerable upper intake level for riboflavin. JECFA and EFSA have evaluated riboflavin and established acceptable daily intakes. Riboflavin is generally considered safe, and deficiency can lead to skin and eye problems, but excess is typically excreted in urine.
Allergen info
Riboflavin is not a major allergen. It does not contain gluten.
