What you get
A 90+ page PDF, formatted for reading.
Every brief includes the mechanism, the evidence, the head-to-head data, the protocol decision tree, an FAQ, and full source citations. Built to be the document you actually open when the topic matters.
The protocol — not just the headline.
The HDN scripts give you the headline. The DEFEND BRIEFS give you the protocol. Decision trees for severity, workup checklists, what to ask your doctor by name, and what to ignore.
No filler. No upsell. No affiliate links.
HDN editorial does not take supplement or clinic sponsorships. The briefs name what works and what doesn't, with citations, regardless of who's selling it.
Yours forever.
One-time purchase. PDF download. Re-read it before your next doctor's appointment, before your next supplement decision, before your next lab panel.
