Calcium, the most abundant mineral in the body, is found primarily in the skeleton where it builds and maintains bones and teeth. Other important functions dependent on calcium include muscle contraction, regulation of heartbeat, and blood clotting. Inadequate calcium intake leads to bone loss and, eventually, osteoporosis. In children, a calcium and vitamin D deficiency may lead to rickets which causes bone deformities and growth retardation. Low calcium levels may also cause muscle spasms, leg cramps, and can contribute to high blood pressure. Calcium supplementation helps prevent osteoporosis and maintains a healthy blood pressure.
Calcium supplements are often combined with other nutrients that offer additional benefits. Here is a guide to different types of calcium supplements.
Calcium with Vitamin D: Vitamin D is often coupled with calcium to facilitate calcium absorption and bone development. Vitamin D is critical for the proper absorption and use of calcium in the body.
Calcium Magnesium & Zinc: Magnesium influences bone metabolism and inadequate intake of magnesium can impair bone growth and ultimately lead to more brittle, fragile bones. Adequate zinc levels ensure proper immune function, wound healing, and are essential for proper vision, taste, and smell.
Calcium Carbonate: Calcium carbonate is best absorbed and tolerated when taken with food in divided doses throughout the day. Sensitive individuals who experience stomach upset (constipation, bloating) with calcium carbonate may better tolerate the calcium citrate form.
Calcium Citrate: Calcium citrate is optimally absorbed when taken without food. Also, for individuals on acid-reducing medication, calcium citrate is a good option since it does not require stomach acid for absorption. Consult with a healthcare professional to choose a calcium supplement that meets your needs.
