Rating (out of 5): 2

Vitamin E, comprising mixed tocopherols and tocotrienols, has been studied for its potential role in supporting the muscular system, primarily due to its antioxidant properties. Oxidative stress is known to contribute to muscle damage and delayed recovery, especially following intense exercise. Vitamin E, as a lipid-soluble antioxidant, can help neutralize free radicals generated in muscle tissues during physical activity. Some animal studies and small-scale human trials have indicated that Vitamin E supplementation may reduce exercise-induced oxidative damage, muscle soreness, and markers of muscle injury, such as creatine kinase levels. Additionally, deficiencies in Vitamin E are associated with muscle weakness and neuromuscular problems, providing further rationale for its role in muscle health.

However, the evidence from large, well-controlled human trials is mixed. While some studies show modest benefits in athletes or elderly populations, others have failed to demonstrate significant improvements in muscle strength, recovery, or performance compared to placebo. The benefits, when observed, tend to be minor and more pronounced in individuals with low baseline Vitamin E status rather than the general population.

In summary, while there is some scientific basis for the use of Vitamin E to support muscle health, particularly due to its antioxidant effects and importance in preventing deficiency-related muscle problems, the overall evidence for substantial benefits in muscle function or recovery in healthy individuals is limited. Therefore, the evidence rating is moderate to low.
