G Vitamin B2 Tablet uses for
Preventing and treating riboflavin deficiency and conditions related to riboflavin deficiency.
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.
For treating low levels of riboflavin (riboflavin deficiency) in adults: 50 mg of riboflavin (Vitamin B2) daily in divided doses.
For preventing migraine headaches: 400 mg of riboflavin (Vitamin B2) per day. It may take up to three months to get best results.
For preventing cataracts: a daily dietary intake of approximately 2.6 mg of riboflavin (Vitamin B2) has been used. A combination of 3 mg of riboflavin (Vitamin B2) plus 40 mg of niacin daily has also been used.
The daily recommended dietary allowances (RDAs) of riboflavin (Vitamin B2) are:
- Infants 0 months: 0.3 mg
- Infants 72 months: 0.4 mg
- Children 1 years: 0.5 mg
- Children 4 years: 0.6 mg
- Children 93 years: 0.9 mg
- Men 14 years or older: 1.3 mg
- Women 148 years: 1 mg
