Ergogenic Supplements and Performance Enhancement

"Walk into any supplement store and you will be surrounded by hundreds of products, each promising more muscle, less fat, more energy, better recovery. The uncomfortable truth is that the overwhelming majority do nothing — and a few of the ones that work do so by margins so small they matter only to people who have already mastered training, diet, and sleep. This book is a filter. It sorts the handful of supplements with real, repeatable evidence from the vast field of hope, marketing, and occasionally danger — and it insists, throughout, that supplements are the last and smallest lever you should pull."

Few areas of health and performance are as profitable, as crowded, and as misleading as the supplement market. Knowing how to think about supplements — what "ergogenic" actually means, how to weigh evidence, why regulation is so weak, and where supplements sit relative to the things that truly drive results — protects your money, your health, and (for athletes) your eligibility. It lets you ignore 95% of the products on the shelf with confidence, invest in the few that work, avoid the dangerous ones, and keep your attention on the training, diet, and sleep that dwarf any pill. Whether you're optimizing your own performance or guiding others, this chapter builds the critical lens for everything that follows — and opens Collection H, the library's deep dive into advanced and supplement nutrition.
