Jarrow FORMULAS Vitamin D3 provides cholecalciferol, the most bioavailable form of vitamin D. Vitamin D3 is converted by kidneys into the hormone calcitrol, the active form of Vitamin D3. Vitamin D3 enhances calcium and phosphorus absorption, stimulates the synthesis of osteocalcin (an important structural protein in bone), and is involved in proper cell differentiation and immune response.
