Can You Get Too Much Calcium?

How much is too much calcium?

Around 1,500 milligrams (mg) per day is all your body really needs, if you are at high risk for osteoporosis. Getting as much as 2,200 mg has been shown to be relatively safe. The safe upper limit for calcium is 2,500 mg per day.

Excessively high amounts of dietary calcium and/or supplements can increase the risk of kidney stones. However, many studies show that normal amounts of dietary calcium may lower the risk of kidney stones.

Some people get more than they need by overdoing calcium and vitamin D supplements, which can boost calcium levels higher than your body can handle. You are not likely to get too much calcium just from food.
