Deficiency

Prevalence

Riboflavin deficiency is uncommon in the United States and in other countries with wheat flour or corn meal fortification programs. From data collected in biannual surveys of the U.S. population, for ages 20 and over, 22% of females and 19% of men reported consuming a supplement that contained riboflavin, typically a vitamin-mineral multi-supplement. For the non-supplement users, the dietary intake of adult women averaged 1.74 mg/day and men 2.44 mg/day. These amounts exceed the RDAs for riboflavin of 1.1 and 1.3 mg/day respectively. For all age groups, on average, consumption from food exceeded the RDAs. A 2001-02 U.S. survey reported that less than 3% of the population consumed less than the Estimated Average Requirement of riboflavin.
