: There is a decline in serum 25 hydroxyvitamin D (25OHD), 1,25 dihydroxyvitamin D (1,25(OH)2D), and calcium absorption with advancing age, which may lead to secondary hyperparathyroidism and bone loss. Studies show a relationship between serum 25OHD and bone density

There is increasing evidence that D-hormones (active vitamin D metabolites) are effective agents in preventing posttransplantation bone loss of various organs. This effect may relate to several mechanisms including reversal of secondary hyperparathyroidism from cyclosporine, reversal of corticosteroid effects on

Alfacalcidol (1-alpha-hydroxyvitamin D3) is a non-endogenous analog of vitamin D which can bypass the renal and intestinal regulatory mechanisms that control the production of calcitriol (1,25-hydroxyvitamin D3, the active form of vitamin D, D-Hormone). Alfacalcidol may be metabolized into calcitriol
