What Are the Dangers of a Calcium Supplements?

Calcium supports bone health and can help prevent osteoporosis, the disease that affects bone density. Most people get the calcium they need through the foods they eat. But for those who don't, supplements may be necessary. Typically safe to take, calcium supplements can cause adverse reactions, especially when your body is getting too much of the mineral.

Nausea

Nausea can occur when you take too much calcium. Your doctor can determine how much calcium is right for you.

Loss of Appetite

Calcium supplements can make you less hungry than usual. With a calcium deficiency, your body will crave foods with the mineral, making you eat more. Once your body is getting the appropriate amount of calcium, it will no longer try to compensate for the loss, decreasing your appetite and possibly slimming your waist line.

Constipation

If you experience constipation, your doctor will either lower the amount of calcium you take, or suggest a laxative.

Increased Urination

Some people experience increased urination when taking calcium supplements. Your doctor will lower the amount of calcium you are taking, or may prescribe additional medication to help deal with your overactive bladder.

Dry Mouth

Large amounts of calcium can cause dry mouth in some patients. Many patients will also experience increased thirst. If you experience either symptom, consult your doctor.
