More vitamin D needed especially needed if organ = liver or kidney (low vitamin d ==> poor bones)
Both regular and active vitamin D have been used
Supplementation can be oral, injection, etc
Extra Vitamin D can be before or after the surgery
Problems avoided include: infection, rejection, death

Vitamin D deficiency is prevalent among patients with end-stage organ failure awaiting transplant. Low serum 25-hydroxyvitamin D (25-OHD) levels in these patients may be related to many disease-specific factors, as well as decreased sunlight exposure and limited intake of foods containing vitamin D.
Low serum 25-OHD levels are also extremely common following solid organ transplantation, both during the immediate postoperative period and in long-term graft recipients.
Demographic and lifestyle factors are important in determining D status in transplant recipients.
Worse vitamin D status is associated with poorer general health, lower albumin, and even decreased survival among these patients.
Although several studies have demonstrated that active forms of vitamin D and its analogues prevent bone loss following transplantation, the data do not show consistent benefit.
These therapies may have particular utility after renal transplantation. However, given the narrow therapeutic window with respect to hypercalcemia and hypercalciuria, and the demonstrated efficacy of bisphosphonates to prevent post-transplantation bone loss, we regard these agents as adjunctive rather than primary therapy for transplantation osteoporosis.
The effects of 1,25(OH)(2)D on the immune system, which are still being elucidated, may have potential for reducing infections and preventing allograft rejection after transplantation. PMID: 21207011
