How it works

Calcium is essential for bone and teeth formation, muscle contraction, and nerve conduction. Vitamin D (as cholecalciferol) undergoes hepatic and renal hydroxylation to form calcitriol, which promotes intestinal absorption of calcium and phosphate and regulates bone metabolism.

Storage
