Calcium, the most abundant mineral in the body, is found in some foods, added to others, present in some medicines (such as antacids), and available as a dietary supplement. Calcium makes up much of the structure of bones and teeth and allows normal bodily movement by keeping tissue rigid, strong, and flexible [ 1 ].

· Calcium is an essential nutrient found in dairy products, dark-green leafy vegetables, legumes, and fortified foods. The most abundant mineral in the body, 99% of calcium is stored in the bones and teeth. Calcium is also important for circulation, hormones, muscle, and nerve health. As we age, calcium levels naturally decline.
