How it works

Calcium is essential for bone mineralization, neuromuscular function, and coagulation. Vitamin D3 (cholecalciferol) is metabolized to its active form calcitriol, which enhances intestinal calcium absorption, reduces renal calcium excretion, and promotes bone health.

Storage

Store at room temperature below 25°C, in a dry place away from direct sunlight.
