Uses

This combination of calcium carbonate, magnesium, and vitamin D3 is used as a dietary supplement to support bone health, prevent calcium and magnesium deficiency, and aid calcium absorption. It is used in prevention and treatment of osteoporosis and osteomalacia.

Do not use if

Contraindicated in hypercalcemia, hypercalciuria, and severe renal impairment. Avoid in patients with a history of calcium-containing kidney stones.

Side effects

Common effects include constipation, bloating, and flatulence. High doses may cause hypercalcemia with symptoms such as nausea, weakness, and confusion. Excessive magnesium can cause diarrhea.

Warnings

Monitor serum calcium levels during prolonged use. Calcium supplements may interfere with absorption of tetracyclines, fluoroquinolones, and thyroid medications if taken simultaneously.

How it works

Calcium carbonate provides elemental calcium for bone mineralization and neuromuscular function. Vitamin D3 (cholecalciferol) is converted to calcitriol, which enhances intestinal calcium absorption. Magnesium is a cofactor for vitamin D metabolism and is integral to bone structure and enzyme activity.

Storage

Store in a cool, dry place below 25°C, away from light and humidity.
