Whether it’s For Yourself, or Your Clients,

Trying to Solve Complex Health Issues Without The Right Information is an Uphill Battle.

Solving complex health issues is no easy feat

Without data to rely on, you’re left to guess about what’s happening within the body, and which protocols are going to restore function most efficiently. With new health information being published daily, it can feel like you’re drinking from a firehose, stuck in a Cycle of Trial and Error™.

A Functional Health Pioneer

Meet FDN Founder | Reed Davis

“Over 20 years ago, I started to recognize a pattern with the people I was trying to help. They were stuck in a Cycle of Trial and Error™…continuously trying new things, but not getting any better. So, I committed to being the last person they saw on their quest for answers. 

Reed Davis

While working with industry leaders in alternative medicine, I ran thousands of labs on thousands of people and learned to identify what I have come to refer to as “healing opportunities.” & “Metabolic Chaos™. I made my own observations about who got better and who didn’t, comparing my natural drug-free protocols to those being used within conventional medicine.  

From there, I developed the FDN Practitioner Certification course to educate and empower as many people as possible to get well & stay well, naturally.”

The FDN certification provides you with a proven methodology to go beyond conventional health coaching, to solve even the most challenging health cases.

What Makes FDN Different?

Test, Don’t Guess.

We believe that data-driven protocols are the key to better health. Our health certification course teaches people to leverage the power of functional testing to get better results.

Our FDN Practitioner graduates get exclusive access to 60+ functional lab tests. FDN teaches you how to identify & correct imbalances within the body using highly-personalized protocols that put an end to Metabolic Chaos™.

Walk The Talk.

We believe the best way to learn is to begin with yourself. Our functional health certification includes the cost of labs in tuition, so you can truly walk the talk before serving clients.

Our mission is to educate as many people as possible, so they in turn can support others in building better health. We’ve designed our certification course to take you through a series of five foundational lab tests to address imbalances within your own body first. It’s a fun & motivating way to learn!

Be The Future.

We believe functional health is the future. Our functional health certification course offers the most advanced diagnostic training in the industry.

Our approach honors bio-individuality with highly-personalized diet & lifestyle protocols that give you & your clients exactly what they need, and nothing they don’t.  As a Functional Diagnostic Nutrition® (FDN) Practitioner, you will have the skills you need to be a true health detective, getting to the bottom of what’s going on, no matter their symptoms or diagnosis. FDN equips you with the most cutting-edge knowledge & support so you can build a thriving business serving others.

“I had already completed the Institute for Integrative Nutrition (IIN) health coach certification, but…

As a client working with an FDN practitioner, I saw how quickly the approach helped me get to the root of my health issues despite doctors saying there was nothing wrong. Having seen the radical transformation in my own health, I knew I had to become certified. I had already completed the Institute for Integrative Nutrition (IIN) health coach certification, but it was clear to me that FDN had another layer of knowledge that would benefit my clients.”
