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 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 the different types of calcium supplements available from Nature Made.

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 Plus Soy: Soy may be added for additive bone health effects and may provide additional benefits for heart and menopausal health.

Calcium Magnesium & Zinc: Magnesium influences bone metabolism and a depletion of it 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 with or without food. Some research suggests calcium citrate is better absorbed than calcium carbonate however, more research is needed for a definite conclusion. Consult with a healthcare professional to choose a calcium supplement that meets your needs.
