Rating (out of 5): 2

Vitamin E has some scientific evidence supporting its use in the management of menorrhagia (heavy menstrual bleeding). Several clinical studies, though limited in size and number, suggest that vitamin E supplementation may help reduce menstrual blood loss. The proposed mechanism involves vitamin E's antioxidant properties and its ability to stabilize cell membranes, which could reduce capillary fragility and decrease bleeding. Additionally, vitamin E may influence prostaglandin synthesis, potentially reducing the vasodilation and increased endometrial blood flow associated with menorrhagia.

A notable randomized controlled trial published in the British Journal of Obstetrics and Gynaecology (1977) found that women who received vitamin E (100 mg twice daily) for five days during menstruation experienced a significant reduction in blood loss compared to placebo. More recent studies and reviews, such as those referenced in integrative gynecology literature, also report modest benefit, though overall evidence remains limited and larger, well-designed trials are needed.

Despite these findings, vitamin E is not universally recommended as a first-line therapy for menorrhagia by major medical guidelines. Its use is considered adjunctive, especially for women seeking non-hormonal or supportive treatments. In summary, while there is some scientific rationale and preliminary evidence for vitamin E's benefit in menorrhagia, the quality and quantity of the evidence support only a modest rating.
