Vitamin E has some scientific basis for its use in the support or adjunct treatment of cervical dysplasia, though the evidence is limited and not robust. Cervical dysplasia, a precancerous condition often linked to persistent human papillomavirus (HPV) infection, is characterized by abnormal changes in the cervical cells. Oxidative stress and impaired antioxidant status are believed to play a role in the progression of cervical dysplasia. Vitamin E (tocopherol) is a potent lipid-soluble antioxidant that can scavenge free radicals and protect cellular membranes from oxidative damage.

Several small studies and clinical trials have examined the effects of vitamin E, often in combination with other antioxidants (such as vitamin C or beta-carotene), on cervical dysplasia. A few have shown that supplementation with vitamin E may help improve regression rates of low-grade cervical lesions or reduce oxidative stress markers in women with cervical dysplasia. For example, a randomized controlled trial published in 2009 found that women with cervical intraepithelial neoplasia (CIN) who received vitamin E supplementation had a higher rate of lesion regression compared to controls. However, these studies are generally limited by small sample sizes and methodological weaknesses.

In summary, while there is a scientific rationale and some preliminary evidence for vitamin E’s use in cervical dysplasia, large, high-quality clinical trials are lacking. Current guidelines do not recommend vitamin E as a standard treatment, and its use should be considered experimental or adjunctive. Patients should always consult their healthcare provider before starting any supplementation for cervical dysplasia.
