Rating (out of 5): 4

Calcium supplementation for premenstrual syndrome (PMS) is supported by scientific evidence. Several randomized controlled trials and meta-analyses have demonstrated that calcium can significantly reduce the severity of PMS symptoms, including mood swings, fatigue, water retention, and pain. The proposed mechanism involves calcium’s role in neurotransmitter regulation and muscle function, both of which may be disrupted during the luteal phase of the menstrual cycle. PMS symptoms have been associated with fluctuations in calcium and vitamin D metabolism, and women with PMS have sometimes been found to have lower serum calcium levels.

One influential study published in the American Journal of Obstetrics and Gynecology (1998) showed that women taking 1,200 mg of calcium daily experienced a significant reduction in PMS symptoms compared to placebo. Subsequent reviews and clinical guidelines, including those from the American College of Obstetricians and Gynecologists (ACOG), recommend calcium as a first-line, evidence-based option for PMS management. Calcium is generally well-tolerated and safe at recommended dosages, making it a practical intervention for many women.

In summary, calcium’s use for PMS is justified by considerable scientific validation, with a relatively high quality of evidence supporting its efficacy for many women experiencing PMS symptoms.
