Calcium

Overview:

Calcium is a vital mineral for the human body, playing a key role in maintaining strong bones and teeth. It is also essential for muscle function, nerve transmission, and blood clotting.

Sources:

Calcium can be found in dairy products such as milk, cheese, and yogurt, as well as in leafy green vegetables, fortified cereals, and juices. Supplements typically come in the form of calcium carbonate or calcium citrate.

Functions:

Bone Health: Calcium is crucial for the development and maintenance of healthy bones and teeth.

Muscle Function: It helps muscles contract and facilitates nerve transmission.

Blood Clotting: Calcium is involved in the coagulation process, aiding in blood clotting.

Deficiency:

A deficiency in calcium can lead to weakened bones, increasing the risk of osteoporosis and fractures. Symptoms of deficiency include muscle cramps, numbness, and tingling in the fingers.

Toxicity:

Excessive calcium intake, particularly from supplements, can lead to hypercalcemia, characterized by symptoms such as kidney stones, constipation, and impaired absorption of other minerals.
