Calcium, vitamin D combat premenstrual ills-study

A diet high in calcium and vitamin D could reduce the risk of getting premenstrual syndrome, according to a report published on Monday.

Previous studies have shown calcium supplements helped treat the problem, but "this is the first, to our knowledge, to suggest that calcium and vitamin D may help prevent the initial development of PMS," said the report.

The study, published in the Archives of Internal Medicine did not say why the combination provided a protective effect.

Bonnie - the combination is effective because calcium and vitamin D are not just essential for bone health. The two nutrients are essential for almost every organ system, especially the endocrine and hormone systems, which affect menstruation.
