Abstract
Aziz was led by circumstances in his own family to realize the neglected importance of vitamin D. Although this account of his experience is written in a very personal style, most people will benefit from several aspects of the book. A general one is the fact that the medical profession is not always sufficiently knowledgeable and helpful, in part because different practitioners take different views and because some of those views are not necessarily well-informed from the primary literature of medical science. A more specific benefit of this book comes from the cornucopia of citations to the scientific literature which reveal things about vitamin D that I imagine few people are aware of.Authors retain copyright to JSE articles and share the copyright with the JSE after publication.
