what is calcium used for

Calcium is a mineral that is essential for building and maintaining strong bones and teeth. It is also important for carrying out many other functions in the body, such as helping muscles to contract, regulating normal heart rhythms, and aiding in blood clotting. Calcium is the most abundant mineral in the body, and almost all of it is stored in bones and teeth. The body gets the calcium it needs in two ways: by eating foods or supplements that contain calcium, and by drawing from calcium in the body. Calcium is found in many foods, including milk, yogurt, cheese, canned sardines and salmon with bones, and certain vegetables such as kale, broccoli, and Chinese cabbage. Calcium supplements are also available in the form of calcium carbonate and calcium citrate. In addition to its role in maintaining bone health, calcium has been suggested to have other potential health benefits, such as protecting against cancer, diabetes, and high blood pressure. Calcium compounds are also widely used in various industries, such as in building materials, water treatment, and the chemicals industry.
