What Is Riboflavin?

Riboflavin, also called vitamin B2, is fundamentally required for the breakdown of carbohydrates, amino acids, and fats in metabolism, enables oxygen to be used by cells, and acts as a component of more than a dozen enzymes involved in energy production and use.

Some enzymes needing riboflavin also require magnesium to properly function.

In other activities, riboflavin is required for healthy cardiovascular and nervous systems, eye health, and supports antioxidant protection.  Functions are more fully described below.

Urinary excretion of riboflavin cannot be detected when vitamin intake is below the required levels. On the other hand, when intake exceeds saturation in the body, the vitamin and/or its metabolites are actively excreted into urine to prevent excessive toxicity of the vitamins.1

There is no specific name for riboflavin deficiency disease.

Understanding Riboflavin (Vitamin B2) Deficiency in Celiac Disease

Riboflavin is a micronutrient, also known as Vitamin B2, which performs many important functions in the body. Riboflavin is a water-soluble vitamin that releases energy from carbohydrates, amino acids, and lipids. It plays a key role in specific amino acid production and provides antioxidant protection. Riboflavin is essential for growth and production of red blood cells and maintaining healthy skin, eyes, hair, and nervous system.

Riboflavin Deficiency

More than 34% of Americans get less than the RDA because, unlike other vitamins, riboflavin is not found in many foods.

Riboflavin depletion and/or deficiency is common before starting the gluten-free diet treatment. It frequently results from malabsorption due to damage to the small intestinal lining, but can also be depleted by excretion through diarrhea, excessive sweating or excessive urination. It is important to note that riboflavin deficiency can result from low serum proteins, which is a common occurrence in untreated celiac disease.

When riboflavin deficiency appears after starting the gluten-free diet, it is usually due to
