Jarrow FORMULAS® Vitamin D3 (cholecalciferol) is derived from cod liver oil and sheep’s wool and is free of Vitamin A. Fat-soluble Vitamin D3 is converted by the kidneys into the hormone calcitriol, the active form of Vitamin D3, which affects a variety of target tissues, including bone, intestine, muscle, brain, skin and immune 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 in prostate cells.

1IU of Vitamin D is equal to 0.025 micrograms of cholecalciferol. Each softgel contains 25 mcg of cholecalciferol.
