*Reducing symptoms of premenstrual syndrome (PMS). There seems to be a link between low dietary calcium intake and symptoms of PMS. Consuming calcium daily seems to significantly reduce mood swings, bloating, food cravings, and pain. Also, increasing calcium intake from food seems to prevent PMS. Women consuming an average of 1283 mg/day of calcium from foods seem to have about a 30% lower risk of developing PMS than women who consume an average of 529 mg/day of calcium. Taking calcium supplements, however, doesn’t seem to prevent PMS.

*Reducing bone loss in people taking drugs called corticosteroids, when used in combination with vitamin D.
*Reducing thyroid hormone levels in people with kidney failure.
* Reversing high potassium levels, when given intravenously (by IV).
