Coral Calcium + Vitamin D3 (Cholecalciferol) is a dietary supplement that supports bone health through two complementary actions.
Coral Calcium is a naturally derived form of calcium carbonate. It supplies calcium, a mineral essential for muscle contraction, nerve signalling, blood clotting, and the formation and maintenance of strong bones and teeth.
Vitamin D3 (Cholecalciferol) helps the intestines absorb calcium more efficiently and regulates calcium and phosphorus levels in the blood. It also supports the parathyroid glands, which control calcium balance in the body.
Together, these ingredients ensure that calcium from the diet and supplements is properly absorbed and used, helping to maintain strong bones and prevent calcium-deficiency conditions.
