Calcium is a mineral most often associated with healthy bones and teeth, although it also plays an important role in blood clotting, and regulating normal heart rhythms and nerve functions.
Your body needs calcium to help muscles and blood vessels contract and expand, to secrete hormones and enzymes and to send messages through the nervous system.
When you don’t get enough calcium, you increase your risk of developing disorders like osteoporosis and osteopenia.
Symptoms of calcium deficiency include:
-
confusion or memory loss.
-
muscle spasms.
-
numbness and tingling in the hands, feet, and face.
-
depression.
-
hallucinations.
-
muscle cramps.
-
weak and brittle nails.
-
easy fracturing of the bones.
