Vitamin E, particularly in the form of mixed tocopherols and tocotrienols, has been studied for its potential role in supporting prostate health. This interest primarily arises from its antioxidant properties, which may help protect cells—including those in the prostate—from oxidative stress and free radical damage, processes implicated in the development of prostate diseases such as benign prostatic hyperplasia (BPH) and prostate cancer. Several observational studies have explored the relationship between vitamin E intake and prostate cancer risk, but the results are mixed. Some early studies suggested a possible protective effect, particularly with certain forms of vitamin E, but large randomized controlled trials such as the SELECT (Selenium and Vitamin E Cancer Prevention Trial) found that vitamin E supplementation did not reduce prostate cancer risk; in fact, it showed a slight increase in risk with alpha-tocopherol supplementation. Research into tocotrienols, a less common form of vitamin E, is ongoing and has shown some anti-cancer properties in laboratory studies, but robust clinical evidence in humans is lacking.

Overall, while vitamin E continues to be included in prostate health supplements and some preclinical evidence supports its antioxidant action, current human clinical trial data do not strongly validate its use for prostate health, and in some cases, suggest potential risks. Therefore, its use for this purpose is justified by limited scientific evidence and should be approached cautiously.
