Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin E, encompassing both tocopherols and tocotrienols, has been studied for its role in eye health, particularly in relation to age-related macular degeneration (AMD) and cataracts. Vitamin E is a potent antioxidant, and oxidative stress is believed to contribute to the progression of several eye diseases. The most significant clinical evidence comes from large randomized controlled trials such as the Age-Related Eye Disease Study (AREDS and AREDS2). In these studies, vitamin E was included as part of a multivitamin supplement formula (with vitamin C, beta-carotene, zinc, and copper) to test its effect on the progression of AMD.

The results indicate that while the combination formula modestly reduced the risk of progression to advanced AMD, there is little evidence that vitamin E alone offers significant protective effects. Furthermore, studies on vitamin E supplementation for cataract prevention have shown limited or no benefit. The evidence for tocotrienols specifically is even less substantial, as most research focuses on alpha-tocopherol.

In summary, there is some scientific investigation into vitamin E for eye health, but the evidence is not strong enough to support its widespread use as a standalone therapy for eye problems. Its use is mostly justified as part of a broader antioxidant formula, rather than as an individual supplement. Therefore, the evidence is rated as 2/5.
