VITAMIN B2
(RIBOFLAVIN)
Also known as:
Riboflavin |
What does it do?
Vitamin B2 is needed to process amino acids and fats, activate vitamin
B6 and folic
acid, and help convert carbohydrates into ATP, the fuel the body runs
on. Under some circumstances, vitamin B2 can act as an antioxidant.
Where is it found?
Dairy, eggs, and meat contain significant amounts of vitamin B2. Leafy
green vegetables and whole and so-called enriched grains contain some
vitamin B2.
Who is
likely to be deficient? Vitamin B2 deficiency can occur in alcoholics.
Also, a deficiency may be more likely in people with cataracts or sickle cell anemia.
How much is usually
taken? Ideal levels remain unknown, but the recommended daily
allowance might be higher than necessary. Vegans
(vegetarians who eat no dairy or eggs) generally consume less than 1 mg
per day of vitamin B2, yet they do not usually show any signs of
deficiency. The amounts found in many multivitamin
supplements (20–25 mg) are more than adequate.
Are there any side effects or interactions? At supplemental
and dietary levels, vitamin B2 is nontoxic.
Vitamin B2 works with vitamins
B1, B3,
and B6;
consequently, vitamin B2 should be taken as part of a B-complex
supplement.
