Why it’s different from everything else being sold to you

Every claim is graded

Nothing is stated more confidently than the evidence allows. Each claim sits on the 8-rung Evidence Ladder — strongest human trials at the top, theory and danger at the bottom — in plain sight.

Every claim is sourced

FDA labels, randomized trials, and regulator statements — cited, not paraphrased. If the evidence is thin, the book says so, instead of filling the gap with confidence.

Nothing to sell you but the book

No doses. No sourcing. No supplements, no clinic, no affiliate links. It explains the science and hands you better questions — the decisions stay between you and your clinician.
