Hi Dee Vitamin D3 is a high-potency supplement containing 50,000 IU of vitamin D3 (cholecalciferol) in soft gelatin capsules. This 8-capsule pack helps treat vitamin D deficiency and supports calcium absorption for healthy bones, teeth, muscles and immune function. Vitamin D3 plays an essential role in calcium and phosphorus absorption from the intestines, which is crucial for bone formation and mineralization. It helps prevent conditions like rickets in children and osteoporosis in adults. The supplement may be beneficial for people with limited sun exposure, those at risk of vitamin D deficiency, or individuals with specific medical conditions requiring high-dose vitamin D supplementation. The soft gelatin capsule format provides optimal absorption of this fat-soluble vitamin.
