A review and clinical summary of vitamin D in regard to bone health and athletic performance

Abstract

The large amount of scientific literature regarding vitamin D can be overwhelming and confusing. Some organizations have made specific guidelines and recommendations regarding optimal blood levels of vitamin D. In the sports medicine literature, new information about the effects of vitamin D on performance and bone health abound. Most of these articles seem to raise more questions than they answer. Are athletes at increased risk of vitamin D deficiency? Does vitamin D deficiency affect athletic performance? Should athletes be tested for deficiency? What is the optimal goal for vitamin D levels in athletes and is this different from the general population? The goal of this article is to provide clinical insight and clarity, both for those practicing in the primary care setting as well as for those taking care of athletes.
