Formulation Notes
Jarrow Formulas Vitamin D3 (cholecalciferol) may help improve Vitamin D status better than equivalent amounts of ergocalciferol (D2). D3 is also the form produced by skin with UVB exposure (sunlight). Vitamin D3 is converted to its hormonally-active form, calcitriol, in the body as needed. Calcitriol enhances dietary calcium and phosphorus absorption, supports the production of osteocalcin (an important structural protein in bone), and supports a healthy immune response.
