If we haven't met...Hello!!

We’re Functional Diagnostic Nutrition (FDN)

We are a team of functional health pioneers, teachers & wellness advocates dedicated to educating and inspiring better health across the world.

It all started over 20 years ago, with FDN Founder, Reed Davis.

While working in the clinic, Reed watched as patients bounced from practitioner to practitioner, only to be told “everything looks normal” or to be convinced of yet another unsuccessful supplement protocol, fitness program, or healing modality.

Reed refused to be just another practitioner in this endless cycle. So he committed to being the last person his clients saw on their quest for answers & better health.

Over years of observation, he developed a proven framework to restore function in the body, no matter what health symptoms or diagnosis a person is struggling with.

That’s how the FDN Certification Course was born!

Today, we’ve trained 4,000+ FDN Health Detectives in 50+ countries across the world on how to apply this framework to themselves and others.

Think you might want to join us?

All of this is at your fingertips.

Seriously, we’re not making this stuff up!
Just ask the health coaches in our community…

Extensive Health Investigation for My Clients

Practitioner in Training

And there’s plenty more where that came from.
