Vitamin E, particularly in its "mixed" tocopherol forms, has been investigated for its potential role in supporting or treating age-related macular degeneration (AMD). The use of vitamin E in this context is primarily based on scientific studies, most notably the Age-Related Eye Disease Study (AREDS and AREDS2), which evaluated the effect of high-dose antioxidant supplementation (including vitamin E) on the progression of AMD. In these studies, vitamin E (400 IU/day) was combined with other antioxidants (vitamin C, beta-carotene, zinc, and copper), and later, lutein and zeaxanthin. The results demonstrated that the combination could reduce the risk of progression to advanced AMD in individuals with moderate to severe disease, but there is little evidence to support vitamin E alone as effective for AMD. Subsequent reviews and meta-analyses have found that vitamin E, by itself, does not significantly reduce the risk of developing or progressing AMD. The evidence supporting its use is therefore modest and largely limited to its role as one component of a broader antioxidant regimen. No major guidelines recommend vitamin E supplementation alone for AMD prevention or treatment. In summary, while vitamin E has scientific basis for inclusion in combination antioxidant therapy for specific AMD patients, its efficacy as a standalone treatment is not well supported.
