Notes for this study:
In a randomized, double-blind, placebo-controlled trial, 66 women with moderate to severe premenstrual syndrome were allocated to take 500 mg of calcium daily or placebo after lunch for two menstrual cycles.

There was a statistically significant and notable reduction in the total score on the Daily Record of Severity of Problems scale in the calcium group as compared with the placebo group, which derived from an improvement in anxiety, depression, emotional, water retention, and somatic changes
