Whether it’s For Yourself, or Your Clients,

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

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™.

Doctors say the labs look "normal", but you know there's something wrong. It's become clear that conventional medicine often falls short.
High-quality supplements can be helpful, but it's hard to know if they're actually working, because you have no way to measure your progress.
Pharmaceutical medications and/or supplements alone only serve to mask the underlying issues & create more chaos within the body (not to mention the unwanted side effects).
Diet & lifestyle changes are helpful, but so often it's two steps forward, one step back, and you need faster, more consistent results.

Ways to Work With FDN

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.

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.

“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.”
