Rating (out of 5): 4

Vitamin B2, also known as riboflavin, has scientifically validated roles in supporting eye health. Riboflavin is an essential nutrient involved in various cellular processes, including the metabolism of carbohydrates, fats, and proteins. One of its most recognized roles in eye health is its function as an antioxidant, helping to protect ocular tissues from oxidative stress, which is implicated in the development of cataracts and other eye disorders.

There is epidemiological and clinical evidence suggesting that adequate riboflavin intake may lower the risk of cataract formation. For example, some studies have observed that populations with higher dietary intake of riboflavin have a reduced incidence of cataracts. The mechanism is thought to involve riboflavin’s role in glutathione regeneration, which is crucial for maintaining lens transparency.

Moreover, riboflavin deficiency has been associated with visual disturbances, including photophobia, eye fatigue, and cataract development. Riboflavin supplementation is used therapeutically in some cases to address such deficiencies and associated symptoms.

Overall, the evidence supporting the use of Vitamin B2 for maintaining eye health is substantial, with both deficiency symptoms and preventive roles well documented in scientific literature. However, while supplementation can help in the context of deficiency, there is less direct evidence supporting its use for eye health in individuals with already adequate dietary intake.
