Jarrow Formulas Vitamin D3 1000 IU
Calcium And Bone Metabolism-Healthy Cell Replication!
Jarrow FORMULAS Vitamin D3 (cholecalciferol) is derived fromcod liver oil and sheeps wool and is free of Vitamin A. Fat-soluble Vitamin D3 is converted by the kidneys into the hormone calcitriol, the activated form of Vitamin D3, which affects a variety of target tissues, including bone, intestine, muscle, brain, skin and immune system cells. Calcitriol enhances calcium and phosphorous absorption and stimulates the synthesis of osteocalcin, an important structural protein in bone. Also, calcitriol is involved in proper cell differentiation (changing of cell function), including prostate cells.
