Vitamin E, particularly in the form of alpha-tocopheryl succinate, has scientific support for its role in supporting aspects of the female reproductive system, though the evidence is moderate and not fully conclusive. Vitamin E is a fat-soluble antioxidant that helps protect cells from oxidative stress, which is significant because oxidative damage is implicated in various reproductive disorders. Clinical studies have shown that vitamin E supplementation may improve certain reproductive parameters in women, particularly those with fertility challenges. For example, some small clinical trials have reported improved endometrial thickness and increased rates of pregnancy in women undergoing assisted reproductive technologies when supplemented with vitamin E. There is also evidence suggesting vitamin E can reduce the severity of dysmenorrhea (painful menstruation) and may have a role in alleviating symptoms of premenstrual syndrome (PMS).

However, the majority of these findings come from studies using vitamin E in general, not specifically the alpha-tocopheryl succinate ester. While this form is bioavailable and often used in supplements, most clinical trials do not distinguish between different tocopherol forms. Systematic reviews and meta-analyses highlight the need for larger, well-designed studies to confirm these benefits and to establish optimal dosages and formulations. In summary, while there is scientific rationale and some clinical evidence for vitamin E’s use in supporting female reproductive health, the strength of the evidence is moderate, and more research is needed.
