NCT ID NCT07575698
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether eating flax and pumpkin seeds in the first half of the menstrual cycle, and sesame and sunflower seeds in the second half, can reduce premenstrual syndrome (PMS) symptoms. 48 healthy women aged 18-35 with regular cycles took part. The goal was to see if this simple diet change could improve physical and emotional symptoms before their period.
