calcium carbonate + cholecalciferol (Medexus Pharmaceuticals)

Calcia is an over-the-counter calcium and vitamin D3 supplement marketed in Canada by Medexus Pharmaceuticals. It is formulated as a chewable tablet containing calcium carbonate and cholecalciferol (vitamin D3). Calcium carbonate provides elemental calcium, which is essential for bone mineralization, muscle contraction, and nerve transmission, and acts as an agonist at the calcium-sensing receptor (CaSR). Cholecalciferol is a vitamin D3 analog that is metabolized to its active form, calcitriol, which acts as an agonist at the vitamin D receptor (VDR) to enhance intestinal absorption of calcium. Calcia is approved and used for the prevention and treatment of calcium and vitamin D deficiencies, as well as supportive therapy for osteoporosis.
