An emergency physician’s honest
read on the supplement aisle.

I’ve spent twenty years in the emergency department, and the last two building an evidence library on men’s health. Most of what’s sold to men my age does nothing measurable. A short list actually holds up — at the right dose, in the right form. This guide is that short list.

The idea

Most supplement stacks are built upside down.

Get your sleep, diet, and exercise settled first. Then there’s a small collection of compounds with “no doubt they work” evidence behind them — the ones to start with. Everything else is “in addition” to these basics. This guide is that foundation, graded honestly.

Everything included

What’s inside

  • How to read supplement evidence like a physician — the tier system, in plain English
  • Test first — the small lab panel worth more than any stack
  • The proven few — a full chapter on each compound that earns its place: what it does, the dose and form the trials actually used, what to expect
  • The near-misses — popular compounds with real but conditional evidence
  • The skip list — what two decades of trials say you can stop paying for
  • The one-page stack sheet — doses, forms, timing — printable
This isn’t a listicle

Behind the guide: a working evidence library.

Every call in the guide traces to a full, referenced monograph. Here’s the kind of thing that means — real writing, not marketing:

Monograph · Fish Oil

“‘Fish oil for your heart’ is largely oversold, because the capsule in most cabinets is not what the trials tested…”

400+ physician-written monographs, each graded by how strong the evidence really is.

Specific answers — not “drink more water”

Things you’ll actually learn.

  • The fish-oil mistake sitting in most medicine cabinets — right molecule, wrong dose
  • The joint supplement with twenty years of trials — and what they actually show
  • The relaxation supplement that struggles to reach the brain at all
  • Why persistent fatigue is a diagnosis problem before it’s a supplement problem
  • The recovery-stack staples that earn their place — and the ones that are marketing
  • The lab test that makes half the supplement aisle irrelevant

Questions

Frequently asked.

Is this medical advice?

No. Education only — written by a physician, but not your physician. The guide repeats this, and means it.

Is this a subscription?

No. $8 once. The membership is a separate thing, and the guide makes an honest case for it — once, at the end.

What if it’s not for me?

Thirty-day money-back, no questions.

How is this different from the free content?

The monographs go deep on one compound at a time. The guide is the synthesis: the short list, sequenced, with doses and forms on one page.

Ready when you are

Start with the proven basics.

I can’t promise transformation — nobody honestly can. I can hand you the short list that survives the evidence, and save you a decade of expensive experiments.
