Vitamin E is a fat-soluble antioxidant that has been investigated for its potential benefits in supporting the muscular system, particularly in the context of exercise, muscle damage, and certain myopathies. Scientifically, Vitamin E’s primary role is to protect cell membranes from oxidative stress by neutralizing free radicals, which can be generated in higher amounts during strenuous physical activity and muscle injury. Some research suggests that Vitamin E supplementation may reduce markers of oxidative damage in muscle tissues after intense exercise. However, evidence for significant improvements in muscle strength, performance, or recovery in healthy individuals is inconsistent and generally weak. Clinical studies have not consistently shown that Vitamin E supplementation improves muscle function in the general population, though there may be some benefit in specific populations, such as individuals with Vitamin E deficiency (e.g., those with certain genetic disorders or fat malabsorption syndromes) who can develop neuromuscular symptoms. Overall, while the biological plausibility exists and some small studies show reductions in exercise-induced muscle damage, the broader scientific consensus is that Vitamin E supplementation has limited and inconsistent benefits for muscle health in otherwise healthy individuals. The evidence does not strongly support routine use for muscle support, resulting in a moderate-low score.
