Vitamin B2 (Riboflavin)
•Required for energy metabolism, enzyme reactions, vision, and skin/hair/nail
health; functions as an antioxidant; activates vitamin B6, niacin, and folate.
•May play a role in preventing migraine headaches and cataracts.
•Defi ciency occurs in alcoholics, the elderly, and those with poor diets.
•Symptoms of defi ciency include sore throat; redness/swelling of the mouth, throat,
tongue, lips, and skin; decreased red blood cell count; and blood vessel growth over
the eyes. Defi ciency may impair iron absorption and increase risk of pre-eclampsia
in pregnant women.
•Drugs that deplete vitamin B2: antibiotics, chlorpromazine, amitriptyline, adriamy-
cin, and phenobarbitol.
•Most people get adequate ribofl avin from diet and/or a multivitamin.
