Supports: Calcium and Bone Metabolism Immune Function
Jarrow Formulas Vitamin D3 provides cholecalciferol, which is more biologically active than ergocalciferol (D2).
Vitamin D3 is ultimately converted to its hormonally-active form, calcitriol, in the kidney.
Calcitriol enhances dietary calcium and phosphorous absorption, stimulates the synthesis of osteocalcin (an important structural protein in bone), and supports a healthy immune response.

Product Description

Jarrow FORMULAS Vitamin D3 provides cholecalciferol, the most bioavailable form of vitamin D. Vitamin D3 is converted by the kidneys into the hormone calcitriol, the active form of vitamin D3. Calcitriol enhances calcium and phosphorus absorption, stimulates the synthesis of osteocalcin (an important structural protein in bone), and is involved in proper cell differentiation (changing of cell function), including in prostate cells. Jarrow FORMULAS Vitamin D3 is tested and verified to be free of vitamin A.
