What it is

Riboflavin, also known as Vitamin B2, is a water-soluble vitamin that occurs naturally in some foods. It is essential for energy production, cell function, and metabolism. It can be produced through fermentation or chemical synthesis.

Why it's used

Riboflavin is often added to foods as a nutrient supplement, particularly in grain products like bread and cereals, to help consumers meet their daily vitamin needs. It is also used as a yellow food coloring agent in various products such as pasta, baked goods, and dairy products.

Health notes

Riboflavin is recognized as safe and effective by the FDA when used as a nutrient supplement or color additive. The World Health Organization (WHO) and the European Food Safety Authority (EFSA) have evaluated riboflavin, and it is considered an essential nutrient. Consuming adequate riboflavin is important for overall health, and deficiencies are rare in developed countries due to fortification and dietary intake.

Allergen info

Riboflavin is not derived from any of the nine FDA major allergens and does not contain gluten. It is considered safe for individuals with common food allergies.
