Calcium is an essential mineral the human body requires for many vital functions. It is one of the most abundant minerals in the body.
Calcium is necessary for the strength and integrity of bones and teeth. It is also vital for muscles to move and nerves to send messages throughout the body.
Without adequate calcium, muscles may spasm and contract, bones may become brittle, and nerves may weaken.
Calcium is absorbed through the intestines and helps maintain proper pH levels in the blood and other fluids in the body.
Calcium is vital to enzyme reactions and cellular communications throughout the body.
It is vital for blood coagulation and clotting when an injury occurs.
Calcium also helps regulate blood pressure and heart rhythm.
Over 99% of the calcium in the human body is stored in the bones and teeth.
Dietary sources of calcium include dairy products, kale, spinach, nuts, and sardines.
Some food items are fortified with additional calcium, including breakfast cereals, orange juice, and tofu.
Calcium supplements are also available, although it is best to obtain nutritional requirements of calcium through food.
