Description
Jarrow Formulas Vitamin D3 1000 IU provides cholecalciferol, which is the form produced by the (human) skin in response to UVB exposure (sunlight), and may also improve vitamin D status better than equivalent amounts of ergocalciferol. Vitamin D3 is converted to calcitriol in the body, which enhances dietary calcium and phosphorous absorption, supports production of osteocalcin (an important structural protein in bone), and supports a healthy immune response.*
