Vitamin Dpromotes the absorption of calcium in the body, and having enough is critical to health and well-being.

Calcium supplements carry risks such as hardening of the arteries or atherosclerosis and an increased risk of heart disease. The NIH recommends 1,000 mg of calcium a day for women ages 19 to 50 and 1,200 mg a day for women age 51 and older; the recommendation for men ages 19 to 70 is 1,000 mg a day and 1,200 mg a day for men age 71 and older. If you have low levels of calcium in your blood despite having an adequate dietary intake, your doctor may prescribe a calcium supplement. It is important to be aware that dietary supplements can have both positive and negative effects on your health.
