The Ineffectiveness of Antioxidant Supplements for Alzheimer's Prevention

Recent research indicates that antioxidant supplements, particularly vitamin E, do not effectively prevent Alzheimer's disease. While studies have shown that a higher intake of vitamin E from food is associated with a lower risk of developing Alzheimer's, the same cannot be said for vitamin E from supplements, as large-scale trials involving over 7,500 older men revealed no protective benefits. Additionally, trials with Alzheimer's patients showed no significant cognitive benefits from vitamin E, with some analyses suggesting it might even be detrimental in certain cases. This lack of efficacy highlights the need for further research into the real impact of antioxidants on cognitive function and disease progression.
