Vitamin E (including both tocopherols and tocotrienols) is an antioxidant nutrient that has been studied for its potential role in supporting nerve health and treating nerve damage, particularly in the context of neuropathies. The scientific justification for its use is primarily based on the observation that oxidative stress is involved in the pathogenesis of various forms of nerve damage, such as diabetic neuropathy and chemotherapy-induced peripheral neuropathy. Vitamin E’s antioxidant properties may help reduce oxidative damage to nerve tissues. Clinical evidence, however, is limited and mixed. Some small randomized controlled trials and observational studies suggest that vitamin E supplementation may offer mild benefit in reducing symptoms of peripheral neuropathy, especially in individuals with vitamin E deficiency (e.g., due to malabsorption syndromes or genetic conditions like ataxia with vitamin E deficiency). There is also some evidence for its use in preventing neuropathy related to certain chemotherapy drugs.

However, for most forms of nerve damage, including idiopathic neuropathies and nerve injuries unrelated to deficiency, the evidence is weak or inconclusive. Large-scale, high-quality clinical trials are lacking, and some studies have failed to demonstrate significant benefit. Therefore, while there is a scientific rationale and preliminary clinical support, the overall evidence supporting vitamin E for treating or preventing nerve damage is modest.
