The Most Comprehensive Functional Testing Training in Clinical Nutrition.
6 specialized tracks. 4 world-class instructors. One program that covers what others charge $16,000+ to teach — for a fraction of the investment.
In Partnership with the Functional Medicine Alliance
Most practitioners finish school with zero confidence in lab interpretation.
You graduated, earned your credential, and then a client hands you their lab work — and you freeze. The markers blur together. The ranges feel arbitrary. You know something is off, but you can't articulate what.
Most nutrition programs teach biochemistry in theory but never teach you how to read a GI-MAP, interpret an organic acids panel, or recognize a cortisol dysfunction pattern on a DUTCH test. So you refer out. Or you guess. Or you avoid labs entirely — and your clients suffer because you can't see what the data is telling you.
This isn't a knowledge problem. It's a supervised practice problem. You've studied the science. What you haven't had is someone who has read thousands of labs sitting next to you, teaching you how to think through what you're seeing.
You don't need another textbook. You need faculty who have interpreted 10,000+ labs to sit beside you and teach you how to think clinically.
Before and after MASTER.
Where You Are Now
- Avoiding functional labs because you're unsure how to interpret them
- Referring clients to other practitioners for testing you should be doing yourself
- Second-guessing every marker, every range, every protocol recommendation
- Charging less because you can't justify premium rates without advanced services
- Feeling like an imposter when clients ask about their lab results
Where You'll Be After MASTER
- Confidently ordering, interpreting, and building protocols from advanced labs
- Running a premium testing practice that commands higher rates
- Seeing patterns in bloodwork, organic acids, and hormones that others miss
- Receiving referrals because YOU are the lab expert in your network
- Operating with clinical precision that sets you apart from every other practitioner
Taught by faculty who teach at Georgetown, Purdue, and Maryland — not course creators who read a book.
In partnership with the Functional Medicine Alliance, your instructors hold doctoral degrees, teach at medical schools, sit on national certification boards, and have collectively interpreted tens of thousands of functional labs. This is not typical online education.
