Calcium and vitamin D may help reduce the likelihood of premenstrual syndrome. Researchers reviewed diet surveys of thousands of nurses aged 27 to 44 years, including 1,057 women who developed PMS over 10 years of follow-up and 1,968 women who did not report having PMS. Women with higher intake levels of calcium and vitamin D were less likely to develop PMS compared to women with lower intakes.
The researchers concluded, “Given that calcium and vitamin D may also reduce the risk of osteoporosis and some cancers, clinicians may consider recommending these nutrients even for younger women.”
