Vitamin therapy after heart transplantation

The need for routine nutritional supplementation with vitamins in most healthy individuals remains a matter of debate and current guidelines recommend that the need for these essential nutrients be met primarily through consuming an adequate diet. However, after heart transplantation, multiple factors, including the effects of prolonged debilitation prior to surgery and immunosuppression, may lead to physiological stress, which may justify consideration for vitamin supplementation. In general, clinical trials have not focused on vitamin supplementation after heart transplantation. There appears to be some limited clinical data to support the use of certain vitamins after heart transplantation. In particular, the putative antioxidant properties of vitamins C and E after heart transplantation may be beneficial as prophylaxis against cardiac allograft vasculopathy, and vitamin D, in conjunction with calcium, may help prevent post-transplant bone loss. Current guidelines only address the use of vitamin D after heart transplantation.
