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.*
Keep out of the reach of children.
