Calcium: A mineral found mainly in the hard part of bones, where it is stored. Calcium is added to bone by cells called osteoblasts and removed from bone by cells called osteoclasts.Calcium is essential for healthy bones and is also important for muscle contraction, heart action, and normal blood clotting.Food sources of calcium include dairy foods; some leafy green vegetables, such as broccoli and collards; canned salmon; clams; oysters; calcium-fortified foods; and soy foods, such as tofu.According to the National Academy of Sciences, adequate intake of calcium is 1 gram daily for both men and women.ood sources of calcium include dairy foods; some leafy green vegetables, such as broccoli and collards; canned salmon; clams; oysters; calcium-fortified foods; and soy foods, such as tofu.
