Calcium supplementation has been found to be effective in the reduction of psychological symptoms of premenstrual symptoms, including sadness, mood swings and anxiety.


Studies suggest that calcium deficiency during the luteal phase of the menstrual cycle can exacerbate PMS symptoms by causing depression, hallucination, and restlessness. Moreover, women who have diets rich in vitamin D and calcium are at a lower risk of developing PMS compared to other women.


In a recent study, researchers found that women with PMS who took a 500 milligram (mg) calcium supplement twice a day for three months had significantly reduced levels of fatigue, appetite changes, and depression than women who took a placebo.
