Hi Dee 50000 IU is a vitamin D3 supplement in soft gelatin capsule form. Each capsule contains 50,000 IU of vitamin D3 (cholecalciferol) to help prevent and treat vitamin D deficiency, support bone health, and aid calcium absorption. Vitamin D3 plays an essential role in calcium absorption and bone metabolism. It helps maintain healthy bones and teeth, supports muscle function, and contributes to proper immune system function. This high-dose formulation is typically used under medical supervision to correct vitamin D deficiency. The supplement comes in a box containing 8 soft gelatin capsules. As with any supplement, consult with a healthcare provider before use, especially given the high dosage strength of this product.
