Preventing and treating riboflavin deficiency and conditions related to riboflavin deficiency.
Possibly Effective for:
Cataracts, an eye disorder. People who eat more riboflavin as part of their diet seems to have a lower risk of developing cataracts. Also, taking supplements containing riboflavin plus niacin seems to help prevent cataracts.
High amounts of homocysteine in the blood (hyperhomocysteinemia). Some people are unable to convert the chemical homocysteine into the amino acid methionine. People with this condition, especially those with low riboflavin levels, have high amounts of homocysteine in the blood. Taking riboflavin for 12 weeks seems to reduce homocysteine levels by up to 40% in some people with this condition. Also, certain antiseizure drugs can increase homocysteine in the blood. Taking riboflavin along with folic acid and pyridoxine seems to lower homocysteine levels by 26% in people with high homocysteine levels due to antiseizure drugs.
Migraine headaches. Taking high-dose riboflavin (400 mg/day) seems to significantly reduce the number of migraine headache attacks. However, taking riboflavin does not appear to reduce the amount of pain or the amount of time a migraine headache lasts. Also, taking lower doses of riboflavin (200 mg/day) does not seem to reduce the number of migraine headache attacks.
