The rational use of dietary supplements and nutraceuticals in clinical medicine

The rational use of dietary supplements and nutraceuticals (DS/N) is based on objective evaluation of the clinical evidence as well as subjective evaluation of the risks, benefits, economic costs, and potential drug interactions. Since the use of DS/N has skyrocketed, physicians must learn about them in order to better communicate with and care for their patients. There are many evidence-based and rational uses for DS/N, but profiteering and quackery must be avoided at all costs.
