Introduction

Vitamin B2 is a water-soluble vitamin needed to process amino acids and fats, activate vitamin B6 and folic acid, and help convert carbohydrates into the fuel the body runs on—adenosine triphosphate (ATP). Under some conditions, vitamin B2 can act as an antioxidant.
Where is it found?
Dairy products, eggs, and meat contain significant amounts of vitamin B2. Leafy green vegetables, whole grains, and enriched grains contain some vitamin B2.

** - Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.

* - For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit.
Who is likely to be deficient?
Vitamin B2 deficiency can occur in alcoholics. Also, a deficiency may be more likely in people with cataracts1 2 or sickle cell anemia.3 In developing countries, vitamin B2 deficiency has been found to be a risk factor for the development of preeclampsia in pregnant women.4 People with chronic fatigue syndrome may be deficient in vitamin B2.5
How much is usually taken?
The ideal level of intake is not known. The amounts found in many multivitamin supplements (20–25 mg) are more than adequate for most people.
Are there any side effects or interactions?
At supplemental and dietary levels, vitamin B2 is nontoxic.
Vitamin B2 works with vitamin B1, vitamin B3, and vitamin B6. For that reason, vitamin B2 is often taken as part of a B-complex supplement.
