Calci 3 500 Mg/0.25mcg Capsule is used for supporting bone strength and calcium balance. It supports bone mineralisation and calcium absorption by combining two essential nutrients: Calcium and Vitamin D3 (Cholecalciferol). Calcitriol, the active form of Vitamin D3, helps regulate calcium and phosphate in the body to promote strong bones and proper nerve function. Calcium carbonate replenishes calcium stores necessary for muscle contraction, nerve impulses and skeletal integrity. Together, these ingredients contribute to maintaining healthy bones, especially in individuals with low dietary calcium intake. Calci 3 500mg/0.25mcg Capsule can be taken with or without food, ideally at the same time each day.
