Administer vitamin D at 400-1000 IU/d to all patients. However, patients with malabsorption, cystic fibrosis, or PBC have higher vitamin D requirements, [12, 91] and 25-hydroxyvitamin D levels should be monitored to assess the adequacy of replacement.

Parent vitamin D at doses of 400-1000 IU daily is insufficient to prevent posttransplant osteoporosis. Active metabolites of vitamin D are more promising in this regard and may work by improving intestinal calcium absorption and directly or indirectly suppressing PTH secretion. [92]
