MASTERPASS · MEMBERSHIP
Learn the science of nutrition from Chris Masterjohn, PhD.
For over 15 years, Chris has helped practitioners, researchers, and self-experimenters understand metabolism, nutrition, and bloodwork at a mechanistic level. Masterpass is where he teaches everything he knows.
15+ years researching nutritional biochemistry
New briefing every month, not every trend
Built for practitioners, researchers, and the self-taught
The science is complex. Understanding your health doesn’t have to be.
Let Chris do the deep reading of the literature
and turn it into clear scientific understanding you can use.
Chris Masterjohn, PhD, takes you inside the research, breaking down the evidence, biochemical mechanisms, and reasoning behind his conclusions. Masterpass gives you access to this deeper level of analysis, helping you build a more sophisticated understanding of nutrition, metabolism, and your health.
WHY MEMBERS JOIN
What You Get With Masterpass:
01
Understand your own metabolism
Chris breaks down the biochemistry and physiology behind nutrition and metabolism so you can understand why a recommendation may work, when it matters, and how to think about it in context.
02
Let a scientist filter the research for you.
Not every headline deserves to change how you think about your health. Chris reviews and analyzes emerging research in context, filtering out the noise and identifying what actually matters.
03
Develop a framework that compounds over time.
Masterpass is designed to deepen your understanding, from foundational biochemistry to advanced topics in nutrition and metabolism. Structured courses take you from foundational biochemistry to advanced, personalized application.
04
Bring your questions directly to Chris.
Through member discussions, Q&As, and live sessions, you can explore complex questions and gain insight into how Chris approaches the evidence and scientific reasoning behind health decisions.

FROM CURRENT MEMBERS
What Members Think After Joining
"I learned more about vitamins and minerals from the Masterclass course than I did in my post-grad certificate in Nutrition and Integrative Health at a well-respected university. I have used the information to help my individual clients and develop successful online programs to help treat Brain Fog."
Nicole L.
Functional Nutrition Practitioner
“Masterpass changed the way I read scientific literature. Rather than chasing headlines, I now have a framework for evaluating research critically.”
Sarah K.
Physician
“Chris has a unique ability to cut through conflicting nutrition advice and explain the mechanisms that actually matter. Masterpass has become one of my most valuable professional resources.”
Phil M.
Integrative Medicine Practitioner
“The depth of the content is remarkable. Chris manages to make complex biochemistry understandable without oversimplifying the science.”
David R.
Functional Nutrition Practitioner
“Instead of memorizing protocols, I finally understand why they work. That shift has made me far more confident when making decisions for myself and my clients.”
Nate Handley.
Health Coach
“Every monthly briefing saves me hours of reading while giving me more confidence that I’m focusing on the studies that truly matter.”
Emily T.
Registered Dietitian
WHY LEARN FROM CHRIS
Deep research, translated for real life.

Before you join
Questions members ask first:
Who is Masterpass for?
Anyone who wants to understand their own biology at a mechanistic level — practitioners, researchers, self-experimenters, and people who've outgrown surface-level wellness advice.
Do I need a science background?
No. Courses start from foundational concepts and build up. What's required is curiosity, not credentials.
How much time does it take?
Courses are self-paced. Most members spend 20–40 minutes a week and treat the briefings and library as an ongoing reference.
How is this different from the free newsletter?
The newsletter shares occasional public insights. Masterpass is the structured, in-depth version — full courses, monthly briefings, protocols, and direct Q&A access.
Can I cancel Anytime?
Yes. There's no lock-in contract on the monthly plan, and annual members can cancel renewal at any time.
