Riboflavin Deficiency
The U.S. Recommended Dietary Allowance (RDA) for riboflavin was revised in 1998, with the goal to prevent riboflavin deficiency. Clinical signs of deficiency in humans may appear at intakes less than 0.5-0.6 milligram per day and excess urinary excretion of riboflavin can be seen at intake levels of approximately 1 milligram per day. Riboflavin deficiency (ariboflavinosis) can be associated with weakness, throat soreness/swelling, tongue swelling (glossitis), angular stomatitis/cheilosis (skin cracking or sores at the corners of the mouth), dermatitis (skin irritation), and anemia. Good dietary sources of riboflavin are milk (and other dairy products), eggs, enriched cereals/grains, meats, liver, and green vegetables (such as asparagus or broccoli). Riboflavin is easily destroyed by exposure to light (for example, riboflavin in milk stored in clear glass bottles).
Particular groups of people may be particularly susceptible to riboflavin deficiency, including the elderly, those with chronic illnesses, the poor, and those with alcohol dependence.
Adults (over 18 years old)
The U.S. Recommended Dietary Allowance (RDA) for adults (by mouth) is 1 milligram for female adolescents (14-18 years old); 1.3 milligrams for male adolescents (14-18 years old); 1.1 milligrams for female adults (older than 18 years); 1.3 milligrams for male adults (older than 18 years); 1.4 milligrams for pregnant women (any age); and 1.6 milligrams for breastfeeding women (any age).
Children (under 18 years old)
The U.S. Recommended Dietary Allowance (RDA) for infants and children (by mouth) is 0.3 milligram for 0-6 months old; 0.4 milligram for 7-12 months old; 0.5 milligram for 1-3 years old; 0.6 milligram for 4-8 years old; 0.9 milligram for 9-13 years old; 1 milligram for female adolescents (14-18 years old); and 1.3 milligrams for male adolescents (14-18 years old).
