Jarrow FORMULAS Vitamin D3 provides cholecalciferol; the most bioavailable form of vitamin D. Vitamin D3 is converted by the kidneys into the hormone calcitriol; the active form of vitamin D3. Calcitriol enhances calcium and phosphorous absorption; stimulates the synthesis of osteocalcin (an important structural protein in bone); and is involved in proper cell differentiation (changing of cell function); including in prostate cells and immune function.* HEALTH CLAIM: Adequate calcium and vitamin D as part of a healthful diet; along with physical activity; may reduce the risk of osteoporosis later in life. Keep out of the reach of children.
