A growing library of guides on nerve health, cognitive health, and metabolic health, written by Michael Fitzmaurice, MD, MS — a fellowship-trained peripheral nerve microsurgeon with twenty years in medicine and more than 3,000 nerve procedures performed.
He came to medicine from exercise science: a degree in exercise science and cardiac rehabilitation, then a master’s in biomedical science, before the MD and a six-year surgical residency. Metabolism, movement, and nutrition were the first things he studied, and his published research covers nutritional strategies for nerve healing. That is why these books treat them as physiology rather than as an afterthought.
They’re for the adult who wants to know why, not just what. Every one of them gives you something to act on. None of them asks you to act on faith.

A Peripheral Nerve Surgeon’s Guide to Nerve Health
The full-length treatment: how nerve tissue actually works and why symptoms persist, a three-pillar protocol you can act on, individual scientific reviews of 12 nerve-supporting ingredients — including where the evidence runs out — and a drug-interaction appendix written for readers over 50 on prescription medication.
The ebook is included free with any NeuroAxis order.
The insulin resistance shift that changes what works
Why the approach that worked at 30 stops working at 45. What actually changes in insulin sensitivity, muscle mass, and sleep after 40, a sixteen-week protocol that adds one layer at a time, which labs to ask for — and sixty named studies so you can check the sources yourself.

Two physician-written guides, free. They answer different questions — pick the one that sounds like where you are.
The insulin–nerve connection, explained. Why fasting glucose and A1c can read perfectly normal while nerves are already under metabolic stress, the three levers you actually control, the questions worth bringing to your next appointment, and the red flags that mean go now. 13 pages.
Get the guide
A peripheral nerve surgeon's five-step protocol — metabolic inflammation, blood sugar, the micronutrients nerves depend on, movement drawn from nerve surgery, and how to read a supplement label. Ends with a "Your First 7 Days" quick-start table you can put on the fridge. 14 pages.

Understanding why your body works the way it does is what makes an intervention stick. These books walk you through the physiology, then hand you the plan that follows from it.
Every claim is tied to the research that supports it. When the evidence is mixed, the book says so. When a popular intervention has weaker support than it’s marketed to have, the book says that too.
Twenty years in medicine. Fellowship-trained peripheral nerve microsurgeon. Over 3,000 nerve procedures performed. These are the conversations once had in exam rooms — written out in full, without the time pressure.
