App D3 Capsule is used for supporting bone health and managing Vitamin D3 deficiency by supplementing Cholecalciferol, a fat-soluble form of Vitamin D. This high-strength formulation, with 60,000 IU of Cholecalciferol in each softgel capsule, plays a critical role in calcium and phosphorus metabolism, supporting skeletal integrity and immune function. The supplement is commonly recommended in cases of Vitamin D deficiency, osteoporosis, and general weakness related to poor calcium absorption. Cholecalciferol enhances intestinal absorption of calcium and phosphorus, which is essential for bone mineralisation and muscular function.
