Rating (out of 5): 2
Vitamin E has been investigated for its potential role in the prevention and treatment of cataracts due to its antioxidant properties. The rationale is that oxidative stress plays a significant role in the development of cataracts, and antioxidants like Vitamin E may help neutralize free radicals in the lens of the eye, thereby slowing or preventing lens opacification. Epidemiological studies have found that higher dietary intake of Vitamin E is associated with a reduced risk of age-related cataracts in some populations. However, randomized controlled trials and meta-analyses have produced mixed results. Some intervention studies have shown no significant benefit of Vitamin E supplementation in slowing cataract progression or preventing cataract formation, while others suggest only a modest effect, if any.
Notably, a 2012 Cochrane review concluded that there is insufficient evidence to support the use of Vitamin E supplements for the prevention or treatment of cataracts. Existing studies often suffer from limitations such as short follow-up periods, varying dosages, and differences in study populations. As a result, while there is a plausible biological mechanism and some epidemiological support, current scientific evidence does not robustly validate the use of Vitamin E supplements specifically for cataract prevention or treatment.
