Riboflavin Vitamin B21

Riboflavin, also known as Vitamin B2, is a water-soluble vitamin that plays a key role in energy production and cell function. It is found naturally in foods like eggs, meat, dairy products, and green vegetables. It can also be produced synthetically for use as a food additive.

Riboflavin is often added to foods as a nutrient supplement, particularly in fortified products like cereals, breads, and dairy alternatives. It can also be used as a yellow food coloring. Its presence is common in baked goods, processed grains, and some beverages.

Riboflavin is an essential nutrient, and the FDA considers it Generally Recognized As Safe (GRAS) when used as a nutrient or dietary supplement. It is vital for metabolism and overall health. JECFA and EFSA have evaluated riboflavin and found it safe for consumption. High doses are generally well-tolerated, with excess amounts excreted in urine. There are no significant controversies regarding its use at typical dietary levels.
