Study Links Vitamin E Intake to Key Fertility Hormone in Women Trying to Conceive - Video

Fertility may begin on the plate more than we realize.

A recent study published in Scientific Reports suggests that everyday nutrient intake could be linked to body composition and hormone levels in women experiencing infertility. As one in six couples worldwide face challenges conceiving, researchers are increasingly exploring how modifiable lifestyle factors—especially diet—might influence reproductive health.

The study examined 97 women aged 18–40 attending a fertility clinic in Spain, focusing on how their dietary patterns related to physical and hormonal markers. Participants typically had difficulty conceiving for at least a year, and conditions like polycystic ovary syndrome and endometriosis were excluded to avoid confounding effects.

Findings revealed a notable imbalance in body composition: most women had higher-than-recommended body fat percentages and slightly lower muscle mass, factors known to influence hormonal balance.

Higher intake of vitamin E was linked to lower prolactin levels—a hormone that, when elevated, can disrupt ovulation and menstrual cycles. Vitamin E intake was also associated with lower hip circumference, suggesting a potential role in fat distribution. Meanwhile, riboflavin (vitamin B2) and calcium intake were positively associated with muscle mass percentage, hinting at their broader role in metabolic and reproductive health.

While some nutrients initially appeared linked to hormones like anti-Müllerian hormone (AMH) and thyroid-stimulating hormone (TSH), these associations were not consistently significant. Importantly, the study does not prove cause and effect due to its cross-sectional design. Still, it highlights diet as a potentially important, modifiable factor in fertility care.

As research evolves, personalized nutrition could become a valuable addition to conventional fertility treatments—offering a practical way to support hormonal balance and overall reproductive health.
