FAQs: Functional Testing & Program

A health detective! In short, an FDN Practitioner is someone who has completed the FDN Course. But on a deeper level, FDN Practitioners are health detectivestrained in investigating underlying causes & conditions, and using evidence-based protocols to restore vitality. FDN Practitioners understand how to select the right functional tests, and exactly what clues to look for when analyzing the results.

FDN Practitioners do not diagnose or treat disease (an area well-attended by licensed physicians). Instead, the FDN methodology teaches you to identify healing opportunities & eliminate contributors to Metabolic Chaos™, which positions you to support just about anyone in building better health!

The most common path forward is to launch or grow a robust private practice, getting paid to do what you love most. However, FDN graduates go on to pursue many different paths in life. Paths you might consider include: 

  • Launching a new health coaching business or private wellness practice 
  • Starting a functional health podcast or YouTube channel
  • Offering wellness consulting to other practitioners or businesses 
  • Sharing your healing journey via a memoir or book 
  • Hosting healing retreats and/or speaking at wellness events

As a graduate of the FDN Course, you are able to use the title “Functional Diagnostic Nutrition (FDN) Practitioner” or “FDN-P”. Some graduates also use the title “Health Coach” but that’s totally up to you & how you want to position yourself in the market!

It’s simple…our methodology teaches you how to get better results. 

That leads to better health for you & your family, endless client referrals & a thriving wellness practice. You also become part of a worldwide community of like-minded practitioners, and have the opportunity to join our graduate program for ongoing support. 

FDN is trusted & well-recognized throughout the world. We have the longest history of training health coaches & professionals in the industry. With FDN, you get exclusive access to order functional tests for you & your clients through our Medical Director Program.

Nope! Our Founder, Reed Davis, is committed to making this knowledge accessible to as many people as possible. All courses are open to anyone looking to expand upon their current knowledge & expertise, whether that’s for personal health or career-advancement. 

Yes, you are! As an FDN Practitioner, you have exclusive access to order 60+ functional labs through our Medical Director Program (MDP). MDP is a full-service lab-testing and clinical support program created to provide unlicensed FDN Practitioners access to lab testing/screenings for themselves and their clients.

After you complete module 1, we’ll ship you (4) functional tests. You will also receive a “Metabolic Typing Assessment”, which is completed online halfway through the program. 

Functional tests sent via mail

  1. Salivary Stress & Hormones Panel (checks cortisol, sex hormones, melatonin)
  2. Metabolic Wellness Urine Profile (assesses digestion, oxidative stress, detoxification)
  3. Dry Blood Mucosal Barrier Assessment (assesses gut function)
  4. Pathogen Stool Screening (screens for gut pathogens)

Honestly, all of them! The FDN methodology teaches you to identify & correct the underlying causes and conditions that lead to people’s health complaints. This method is not only safe and effective, but often outperforms conventional treatment, ending the Cycle of Trial and Error™ that many clients (and health professionals) are stuck in. 

By combining highly-strategic functional tests with extremely thorough client intake processes, you’re able to create protocols that support every cell, tissue, organ and system in the body.
