Vitamin E, encompassing both tocopherols and tocotrienols, is an antioxidant vitamin that has been investigated for its potential role in muscle health. The primary scientific rationale is its capacity to protect cell membranes from oxidative damage, which is relevant because muscle tissues are particularly susceptible to oxidative stress during exercise and aging. Some clinical and preclinical studies suggest that Vitamin E deficiency can lead to muscle weakness and structural abnormalities, highlighting its essential role in normal muscle function.

However, evidence supporting the use of Vitamin E supplementation (beyond correcting deficiency) to enhance muscle strength, prevent muscle injury, or improve recovery in healthy individuals or athletes is limited and inconsistent. A handful of small-scale studies report modest benefits in reducing exercise-induced muscle damage and inflammation, but large, well-controlled trials often fail to show significant improvements in muscle performance or recovery with supplementation. The use of Vitamin E to treat muscle disorders such as muscular dystrophy has not demonstrated robust clinical benefits.

In summary, while Vitamin E is essential for maintaining normal muscle physiology and preventing deficiency-related muscle symptoms, scientific evidence supporting supplementation for muscle enhancement or protection in non-deficient individuals is weak. The overall body of research does not justify widespread use of mixed tocopherols and tocotrienols specifically for muscle system support beyond correcting deficiency.
