Calcium is the most plentiful mineral in the body. It is found in some foods and is available as a dietary supplement. Calcium has many functions but is probably best known for preserving teeth and bones. Our bodies need calcium to function properly. It assists in the transmission of signals in nerve cells, and plays a role in muscle contraction. But when a surplus of calcium is present, our bodies can have a variety of negative responses.
Target Amounts of Calcium
The National Institute of Health says the tolerable daily amount calcium for male and female adults ranges from 1,000 to 1,300 mg.
Hypercalcemia
When extremely high levels of calcium are in the blood, a condition called hypercalcemia may develop and weaken kidney function. However, the National Institute of Health says hypercalcemia is rarely caused by taking calcium supplements. It is usually associated with advanced cases of cancer or massive doses of vitamin D and hyperparathydroidism.
Hyperparathyroidism
Hyperparathyroidism is defined as an overabundance of calcium in the bloodstream because of over-activity in one or more of the four parathyroid glands that sit at your neck.
These tiny glands produce parathyroid hormone, which helps maintain the right level of calcium in the bloodstream and tissues that rely on the mineral to function correctly.
Hyperparathyroidism may be caused by dysfunctional parathyroid glands. There may be little sign that you have hyperparathyroidism, but symptoms can include kidney stones, abdominal pain, bone and joint pain, osteoporosis, depression, forgetfulness, nausea and lack of appetite.
If you are diagnosed with this condition your doctor may opt to take a wait-and-see approach, prescribe medications, or, in some cases, surgery is recommended.
Early Indications of Calcium Overdose
The Mayo Clinic lists several possible reactions that your body may have to excess amounts of calcium. They include severe constipation, an ongoing headache, fatigue, dryness of mouth and or a metallic taste in the mouth. Sometimes excess amounts of calcium can cause depression, irritability and loss of appetite.
Late Warning Signs of Calcium Overdose
The later signs of calcium overdose may become more serious in nature. According to the Mayo Clinic they may include high blood pressure, an irregular heartbeat, severe drowsiness and an increase in the amount and/or frequency of urination.
Taking Calcium Supplements
Unless otherwise directed by your doctor, it is best to take a calcium supplement an hour to an hour and a half after eating. You should take it will a full glass of water or juice.
