Calcium is an essential mineral needed every day for proper health. 99% of the body’s calcium can be found in the bones. This mineral provides the building blocks that help keep bones and teeth strong and healthy.* In addition, calcium helps to support the health of other systems in the body, including the heart, musculoskeletal and nervous systems. This formula contains Vitamin D3 to enhance the absorption of calcium.* Adequate calcium throughout life, as part of a well-balanced diet, may reduce the risk of osteoporosis.
