Risk factors People at risk of having low riboflavin levels include alcoholics, vegetarian athletes, and practitioners of veganism. Pregnant or lactating women and their infants may also be at risk, if the mother avoids meat and dairy products. Anorexia and lactose intolerance increase the risk of riboflavin deficiency. People with physically demanding lives, such as athletes and laborers, may require higher riboflavin intake. The conversion of riboflavin into FAD and FMN is impaired in people with hypothyroidism, adrenal insufficiency, and riboflavin transporter deficiency.
