Vitamin E deficiency can drive a progressive neurologic syndrome, including ataxia, sensory neuropathy, and myelopathy, because α‑tocopherol is a critical fat‑soluble antioxidant that protects neuronal membranes and prevents peroxidation of polyunsaturated fatty acids under oxidative stress. In both children with chronic cholestatic liver disease and adults without obvious fat malabsorption, low vitamin E status has been linked to characteristic large‑fiber sensory axonopathy and other degenerative changes, illustrating that unrecognized deficiency can present with strikingly “neurologic‑first” symptoms. When vitamin E deficiency is identified early, appropriately dosed, bioavailable α‑tocopherol supplementation can stabilize or partially reverse neurologic findings in some patients, underscoring the importance of screening at‑risk groups and not dismissing isolated ataxia or neuropathy as purely genetic or idiopathic. This medication is commonly used for High Cholesterol.

Research demonstrates that fibrates, particularly fenofibrate, are known to increase homocysteine levels. Elevated levels of homocysteine is associated with increased risk of a range of health problems including atherosclerosis, stroke, and neurological diseases, and vitamin Bs including vitamin B6 helps facilitate the breakdown of homocysteine and may be helpful in reducing homocysteine levels.
Fenofibrate has been shown in studies to increase the toxic effect of ultraviolet (UV) radiation that may lead to side effects such as hives, itching, and skin rash. Taking vitamin E before UV exposure is found in research to significantly help block UV-fenofibrate effects on the skin. Vitamin E supplementation should be considered when taking this drug therapy.
