Vitamin E, comprising mixed tocopherols and tocotrienols, has been investigated for its role in supporting the muscle system, primarily due to its antioxidant properties. Scientific evidence suggests that Vitamin E helps protect muscle cells from oxidative stress caused by free radicals, which can be generated during intense physical activity or as a result of certain muscle disorders. Several animal and human studies indicate that Vitamin E deficiency can lead to muscle weakness and damage, which can be reversed with supplementation. For example, severe deficiency has been associated with myopathy and neuromuscular problems in both animal models and rare human cases.

However, in healthy individuals, the evidence supporting Vitamin E supplementation for enhancing muscle strength, performance, or recovery is limited and inconsistent. Some small studies have reported reduced markers of muscle damage and inflammation after strenuous exercise in athletes taking Vitamin E, but meta-analyses and larger clinical trials generally do not find significant benefits for muscle function or soreness prevention compared to placebo. In summary, while Vitamin E is essential for normal muscle health and severe deficiency can impair muscle function, there is only modest scientific support for its use in improving muscle performance or recovery in the general population.
