Composition Coral calcium 225mg softgel capsule
Indication Post-menopausal osteoporosis & senile osteoporosis
Mechanism of Action

Coral calcium is composed primarily of calcium carbonate (CaCO3), with small amounts of magnesium and other trace minerals. Calcium carbonate from coral is similar to calcium carbonate from other sources, with varying amounts of trace minerals. Much attention has been given to calcium carbonate's ability to change the pH (or alkalinity) of water-based solutions to which it is added. With respect to pH and alkalinity, the calcium component is less important than the carbonate component, which is chemically similar to the bicarbonate in baking soda. Coral calcium is a source of calcium, which is an essential mineral for human life. Coral has a chemical structure that is very similar to the composition of human bone and is sometimes used as material in bone grafts


Absorption: Absorption of calcium intake varies with age (infants 60%, prepubertal children 28%, pubertal children 34%, adults 25%); during pregnancy, calcium absorption doubles; calcium is absorbed in soluble, ionized form; solubility of calcium is increased in an acid environment

Distribution: Primarily in bones, teeth

Excretion: Primarily faeces (75%; as unabsorbed calcium); urine (22%)

Protein Binding:~40%, primarily to albumin

Side effects

Symptoms of kidney stones may include severe pain that starts around the flank or back and travels to the lower abdomen, groin or urinary tract, chills, painful urination, red or pink urine, nausea, vomiting, fever or upset stomach


Gastrointestinal effects: Constipation, bloating, and gas are common with calcium supplements

Hypercalcemia: Chronic Hypercalcemia may result in vascular calcification and other soft-tissue calcification
