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 kidneys. Calcitriol
enhances dietary calcium and phosphorous absorption, stimulates the synthesis
of osteocalcin (an important structural protein in bone), and supports a
healthy immune response.*
