This combination supplement provides calcium, vitamin D3, and vitamin K1 to support bone health and treat calcium deficiency. Calcium carbonate serves as a source of elemental calcium, while cholecalciferol enhances calcium absorption from the intestines. Vitamin K1 supports proper calcium utilization and bone metabolism. This medication is commonly used in patients at risk for osteoporosis, postmenopausal women, and elderly individuals with insufficient dietary calcium and vitamin D intake.

Treatment and prevention of calcium deficiency states; osteoporosis prevention and management; osteomalacia; support for bone health in postmenopausal women, elderly patients, and those with limited sun exposure or inadequate dietary calcium intake.
Calcium carbonate provides elemental calcium for bone structure and cellular function. Cholecalciferol (vitamin D3) is converted to calcitriol, which enhances intestinal calcium and phosphorus absorption. Vitamin K1 serves as a cofactor for gamma-glutamyl carboxylase, which activates osteocalcin—a protein that helps bind calcium to the bone matrix.
Take with food for optimal calcium carbonate absorption. Separate dosing by 2 hours from other medications, particularly antibiotics (tetracyclines, quinolones) and thyroid medications. Avoid in hypercalcemia, severe renal impairment, or vitamin K contraindications. Monitor for constipation or kidney stone risk. Healthcare provider supervision recommended for long-term use.
