What is Riboflavin
Riboflavin, or vitamin B2, is among the eight B vitamins that are vital for maintaining your health. It plays a crucial role in absorbing other nutrients, breaking food components, and preserving tissue health.
Role of Riboflavin in Your Body
Riboflavin is an indispensable part of enzymes that regulate cellular function, energy production, and the metabolism of drugs and fats.
Recommended Dietary Allowance
The recommended daily allowance of riboflavin for men is 1.3 mg a day, and for women, it is 1.1 mg a day. The need increases during pregnancy and lactation, when the doses are 1.4 mg and 1.6 mg a day, respectively.

What are the symptoms of riboflavin deficiency?
The signs and symptoms of riboflavin deficiency (also known as ariboflavinosis) include skin disorders, hyperemia (excess blood) and edema of the mouth and throat, angular stomatitis (lesions at the corners of the mouth), cheilosis (swollen, cracked lips), hair loss, reproductive problems, sore throat, itchy and red eyes, and degeneration of the liver and nervous system [ 1-3, 8 ]. People with riboflavin deficiency typically have deficiencies of other nutrients, so some of these signs and symptoms might reflect these other deficiencies. Severe riboflavin deficiency can impair the metabolism of other nutrients, especially other B vitamins, through diminished levels of flavin coenzymes [ 3 ]. Anemia and cataracts can develop if riboflavin deficiency is severe and prolonged [ 1 ].
