his guide for clinicians would not have been possible without the scien- tific expertise of the many authors and peer reviewers who dedicated their time
to ensuring each chapter is reflective of current science. In addition to my edito- rial review, each chapter in this textbook was peer-reviewed by at least two subject matter experts to ensure the utmost quality. Please refer to page 641 for a complete list of reviewers. Thank you to Betsy Hornick, MS, RDN, at the Academy of Nutrition and Dietetics for assisting in the planning, organization, and development of the book, and to Christina West for her editorial services. I am forever grateful to Drs Johanna T. Dwyer and Joseph M. Betz at the National Institutes of Health Office of Dietary Supplements for assembling a comprehensive Introduction for the book that addresses many of the common questions health professionals have about dietary supplements and highlights the extensive government resources available for both consumers and health professionals. This book is dedicated to the great internal team and external network of accomplished researchers that have together helped grow Think Healthy Group beyond my wildest dreams. It is through innovative research, collaborative efforts, and strong scientific societies like the Academy of Nutrition and Dietetics that nutrition and food science will achieve both a healthier population and planet.
