Vitamin E, specifically as gamma-tocopherol, has been investigated for its potential role in supporting or treating age-related macular degeneration (AMD). The rationale is based on Vitamin E’s antioxidant properties, which could theoretically help counteract oxidative stress implicated in retinal degeneration. However, the main scientific evidence comes from large randomized controlled trials, such as the Age-Related Eye Disease Study (AREDS and AREDS2), which primarily used the alpha-tocopherol form of Vitamin E (400 IU daily) in combination with other antioxidants (vitamin C, beta-carotene or lutein/zeaxanthin, zinc, and copper). These studies found that this combination could modestly slow the progression of intermediate to advanced AMD, but the benefit could not be attributed to Vitamin E alone.

Gamma-tocopherol, the most common form of Vitamin E in the American diet, has not been directly studied in large AMD trials, and there is currently no robust clinical evidence to support its unique use for this condition. Thus, while Vitamin E is included in some eye health supplements, the scientific validation for gamma-tocopherol specifically is lacking, and the overall evidence for Vitamin E’s effect (regardless of form) in AMD is considered modest at best. Most clinical recommendations are based on the broader antioxidant combination, not Vitamin E alone or in the gamma-tocopherol form.
