Riboflavin (B2) & Eye Health
April 13, 2012
It’s also solely responsible for the fluorescent-yellow color in urine of people who supplement with high dose B-complex vitamins.
Because the vitamin B2 dependent enzymes, flavoproteins, are involved in the metabolism of other B vitamins, including Vitamin B6, niacin and folic acid, B2 deficiency can affect many enzyme systems.
B2 deficiency is linked to formation of blood vessels in the clear covering of the eye (vascularization of the cornea).
Age-related cataract has proven to increase in those who are vitamin B2 deficient. One Australian study of both men and women suggested the incident of age-related cataract was 50% less likely to have cataracts in those in the highest riboflavin intake than those in the lowest riboflavin intake.
Riboflavin (B2) Food Sources
Fortified cereals, milk, cheese, eggs, almonds, salmon, chicken, beef, broccoli, asparagus, spinach and fortified breads.
Riboflavin (B2) Safety
According to the Food & Nutrition Board at the Institute of Medicine, no toxic or adverse effects of high supplemental riboflavin intake in humans are known.
The Biosyntrx full-spectrum multiples, Macula Complete and Oculair, include 10 mg of vitamin B2 in each recommended daily dose.
