127 supplements. One page each. Graded A to F on the published human evidence for the claim each one is sold on. Ten earned an A. Twenty-eight earned a D or an F. The rest sit somewhere in between, which is an honest picture of a field where most things do a little, some do nothing, and a handful do quite a lot. No brands. No sponsors. No affiliate links. No product is named as good. What every entry gives you The same fourteen fields: what it actually does, what the research shows, the dose the studies used, what it costs per effective dose, who it is worth it for, who should skip it, the label red flags, and the drug interactions. The dose line is the one that saves you money. Hold it against the number on the tub and most of the shelf disqualifies itself in seconds. The other half of the book The Label Decoder takes apart ten techniques a label legally uses to look like more than it is: proprietary blends, protein spiking, fairy dusting, serving size games, and the legal reason claims are worded the way they are. Also inside The Short List: the fifty-one that earned an A or a B The Waste List: the twenty-eight that earned a D or an F By Goal: all 127 sorted into the ten things people actually buy supplements for Where the book says be careful: every drug interaction, liver signal and banned-in-sport status in one place A glossary, an A-Z index of every name and alias, and a one-page label check to print What it is not Educational, not medical advice. It does not tell you what to take. Doses are reported from research protocols, never prescribed. 185 pages. PDF.
