A countless number of new, renamed, and variations of sport supplements flood the market each year. Many of these are accompanied by slick marketing campaigns promising too-good-to-be-true results. For athletes seeking a safe, effective edge to their training and performance, supplements can be a confusing and serious matter.

The Athlete's Guide to Sports Supplements separates fact from fiction, provides quick answers to the most common questions, and delivers information you can trust.

Sport nutrition and supplement experts Kimberly Mueller and Josh Hingst provide concise descriptions for 120 of today's most popular supplements. For each entry, you'll discover what it is, how it works, potential performance benefits, research studies and outcomes, dosage recommendations, and possible health concerns. You'll also find recommendations for master's athletes, those competing in extreme environments, and those with special dietary needs, such as food allergies, diabetes, and vegetarian.

Best of all, each supplement is listed alphabetically, providing quick and easy navigation throughout the book. Alternatively, use the supplement finder to locate supplements for a particular purpose, such as recovery, endurance, and strength. And for ease of searching, many of the supplements are thoroughly cross-referenced by scientific and popular names.
