Hi Dee Vitamin D3 is a high-potency supplement containing 50,000 IU of cholecalciferol (Vitamin D3) per soft gelatin capsule. This 8-capsule pack helps maintain healthy bones, teeth, and immune function by supporting proper calcium absorption and utilization in the body. Vitamin D3 (cholecalciferol) plays a crucial role in calcium and phosphorus absorption from the intestines, which is essential for bone formation and mineralization. This supplement may be beneficial for those with vitamin D deficiency, at risk of osteoporosis, or with limited sun exposure. The soft gelatin capsule format provides optimal absorption. As this is a high-dose supplement, it should be taken under medical supervision.
