Adequate Intake (AI): Intake at this level is assumed to ensure nutritional adequacy; established when evidence is insufficient to develop an RDA. The federal government's 2015-2020 Dietary Guidelines for Americans notes that "Nutritional needs should be met primarily from foods. Recommended Dietary Allowance (RDA): Average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%–98%) healthy individuals; often used to plan nutritionally adequate diets for individuals. 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]. Vitamin B2 was originally known as ovoflavin since it was a flavin derived from eggs. An essential nutrient for animals, it can be synthesized by green plants and by most bacteria and fungi.

In adults aged 20 and older, the average daily riboflavin intake from foods and supplements is 4.5 mg in men and 4.7 mg in women. In people who eat meat and dairy products, these foods contribute a substantial proportion of riboflavin in the diet. The nucleotide part of the molecule does not enter into any chemistry, but is important for recognition and binding to enzymes that will use FMN or FAD as a cofactor. The greenish yellow fluorescence of whey and egg white is caused by the presence of riboflavin, which was isolated in pure form in 1933 and was first synthesized in 1935. Poor thiamin and riboflavin status is common among women of childbearing age in rural and urban cambodia. [, Dainty JR, Bullock NR, Hart DJ, Hewson AT, Turner R, Finglas PM, et al.

Estimated Average Requirement (EAR): Average daily level of intake estimated to meet the requirements of 50% of healthy individuals; usually used to assess the nutrient intakes of groups of people and to plan nutritionally adequate diets for them; can also be used to assess the nutrient intakes of individuals. Some, but not all, of the few small studies conducted to date have found evidence of a beneficial effect of riboflavin supplements on migraine headaches in adults and children. DRI is the general term for a set of reference values used for planning and assessing nutrient intakes of healthy people. Because riboflavin is required for mitochondrial function, researchers are studying the potential use of riboflavin to prevent or treat migraine headaches [42]. Riboflavin status is not routinely measured in healthy people. These coenzymes play major roles in energy production; cellular function, growth, and development; and metabolism of fats, drugs, and steroids [1-3]. The risk of riboflavin loss from exposure to light is the reason why milk is not typically stored in glass containers [3,5]. Riboflavin deficiency is endemic in populations consuming little milk or meat products. J Headache Pain 2009;10:361-5. However, the cellular mediators of H2O2-induced cell death are unknown. The average daily riboflavin intake from foods and supplements in children and teens is 2.1 mg for ages 2–5 years, 2.2 mg for ages 6–11, and 2.3 mg for ages 12–19.

The NOEL for 98% pure riboflavin produced by fermentation was 200 mg/kg bw per day, which was the same as that for chemically synthesized riboflavin. As a result, these patients cannot properly absorb and transport riboflavin, so they develop riboflavin deficiency. Dietary intake and nutritional status of young vegans and omnivores in Sweden. Riboflavin is an orange colored, water soluble vitamin. Riboflavin (vitamin B 2) is an essential nutritional factor for humans and animals who need it as a precursor to flavoproteins. The results showed a significant inverse association between dietary riboflavin intake and lung cancer risk in current smokers (fifth versus first quintile) but not former or never smokers. This technique is less accurate for reflecting long-term riboflavin status than EGRAC [1,6]. Foods providing 20% or more of the DV are considered to be high sources of a nutrient, but foods providing lower percentages of the DV also contribute to a healthful diet. Neurology 2009;72:1588-94. Deficiency of riboflavin in rats causes growth retardation, dermatitis and eye lesions.
