Riboflavin (Vitamin B2)
Gen:
Vitamin B2, also called riboflavin, is one of eight B vitamins. All B vitamins help the body to convert food (carbohydrates) into fuel (glucose), which is used to produce energy.
These B vitamins, often referred to as B-complex vitamins, also help the body metabolize fats and protein. B-complex vitamins are necessary for a healthy liver, skin, hair, and eyes. They also help the nervous system function properly.
Mechanism of Action:
In addition to producing energy for the body, riboflavin works as an antioxidant, fighting damaging particles in the body known as free radicals.
Free radicals can damage cells and DNA and may contribute to the aging process, as well as the development of a number of health conditions, such as heart disease and cancer.
Antioxidants, such as riboflavin, can fight free radicals and may reduce or help prevent some of the damage they cause.
Dosage:
Daily recommendations for adults are as follows:
Men, 19 years and older: 1.3 mg (RDA).
Women, 19 years and older: 1.1 mg (RDA).
Pregnant women: 1.4 mg (RDA).
Breastfeeding women: 1.6 mg (RDA).
Please consult a healthcare provider before giving riboflavin supplements to those 18 years of age or younger.
Precautions:
Riboflavin is generally considered safe, even at high doses. Riboflavin does not seem to cause any serious side effects. However, extremely high doses may cause itching, numbness, yellow or orange urine, or sensitivity to light.
Interactions:
Please speak to healthcare professional when taking riboflavin with anticholinergic medications, tetracyclines, tricyclic antidepressants, antipsychotic medication, thiamine diuretics, phenytoin, and doxorubicin.
