Anyone can order or run lab tests these days, but without a complete understanding – most people end up chasing the test results instead of helping the person get to the core of their health issues. Symptoms are not the problem, and test results are not the problem either. Symptoms and test results are both the result of the problem!

Have you ever wondered why some people get better while others can’t seem to break the cycle no matter who they go to or what they take? Maybe even yourself included? Don’t worry, you’re not alone. Helping people who just can’t seem to get better is what separates the good health practitioners and coaches from the great ones – that’s the Functional Diagnostic Nutrition® difference.

FDN’s are true health detectives that focus on identifying the underlying cause of Metabolic Chaos® and correcting it. We utilize functional lab tests to help identify which systems of the body are failing, leading to Metabolic [email protected] and imbalance. Then we use the lab data and assessments to drive more specific holistic lifestyle changes and recommendations geared towards establishing homeostasis (balance) in the body. The FDN Certification Course focuses on functional lab tests (blood, saliva, urine, hair and stool testing); how to interpret the results and lab-guided natural protocols that will fix the problem, build health and ultimately stop the cycle of Metabolic Chaos®.


Along with the functional lab work and trademarked health-building protocol training, you’ll learn to fix yourself so you can help fix others too. As part of the course, you’ll run lab tests on yourself, receive your own personalized consultation and FDN D.R.E.S.S. for Health Success® protocol. The FDN Mentoring portion of the program will help guide you on your own health journey and give you the practical application to grow your confidence so you can easily duplicate the process with your own clients.

After taking the FDN course, you’ll know how to create change for yourself and for your clients. The insights you’ll receive about your own health alone worth the price of admission – the tools to help you start your own business are the icing on the cake. FDN is science and evidence-based, providing people who want to get into health coaching the foundation they need to get started, and giving licensed and non-licensed health practitioners a leg up on any other health-building system – meaning you can take any system you are currently using, add the FDN methodology and you will arrive at a whole new level. Your ability to help people will be multiplied several times over. Applying FDN will help you get REAL RESULTS for you and your clients, that will last a lifetime.

This is an introduction to the FDN model and philosophy, especially compared to the standard medical approach in Western medicine.    Stress and Metabolic Chaos® are defined and explained within the context of FDN, and lab tests are introduced as a significant tool in the FDN Practitioner’s toolbox.

This lesson presents a deep look at the Hypothalamus/Pituitary/Adrenal Axis, the significance of dysregulated cortisol, and the first page of the BH205A Adrenal Stress Profile.    FDN Clinical Ranges are taught based on the Three-Stage Model of Stress Adaptation, in contrast to “normal” levels within lab ranges.

This lesson outlines the second page of the BH205A, the sex hormones, and how FDN approaches testing in premenopausal females.   The male and female hormone cycles are investigated, as are common symptoms relating to deficiencies and excesses of each sex hormone.

This lesson provides insight into the BH101 Metabolic Assessment Profile and breaks down each marker on the test including indican, oxidative stress, and detoxification indicators.   Emphasis is placed on the importance of the liver, and how to manage various therapies utilizing the BH101.

This module reviews the physiology and significance of the mucosal barrier and its role in digestive health. The Genova Intestinal Permeability test is detailed with explanations of large and small particles that may pass through the mucosal barrier and the utility of the ratio between these molecules.

This lesson is an introduction to the possible effects of a malfunctioning GI environment, and therefore, the importance of a healthy gut.   Bacteria, parasites, yeasts, and specific species of each are detected on the BH401H GI Pathogen Screen.   The idea that bugs are not the problem, they are the result of the problem is explored in this module.

Options for food sensitivity testing are presented in this lesson, along with scientific explanations for why and how they function.   The Great Plains IgG Fingerstick and the Oxford Biomedical Mediator Release Test are explained in detail, along with guidelines for reintroducing sensitive foods, and retesting.

This lesson marks the end of the training on lab tests and interpretation of their results and stresses the importance of being intimately familiar with the five foundational labs and collecting your own samples.   The Test Comparison Worksheet is introduced to segue into the next section of the course, D.R.E.S.S. for Health Success® Protocols, and an overview of the D.R.E.S.S. for Health Success® Program is presented.   This is also the point in the course where the Written Final Exam is available to download and begin working on to submit at the end of the FDN program.

This module outlines the intakes and case notes forms used by FDN Practitioners to facilitate taking a detailed history of each client and keeping organized notes throughout your relationship with them.   Once the lesson on intake forms is complete, personal intake forms can be submitted in preparation for the Personal Results and Recommendations (R&R) Session with an FDN Mentor.

This lesson goes into extreme detail for each of the five pillars of the D.R.E.S.S. for Health Success® method, to address a vast array of Metabolic Chaos® when customizing client protocols.

This part of the course covers the components of the R&R sessions FDNs have with their clients.  Major focus in this module is on utilizing FDN documents and building 90-Day Protocols.

This is the final module in the FDN Certification Course, which explains the logistics and best practices of the onboarding and intake process.   The complete FDN method is reiterated to set you up for success as you prepare to complete your practical exercises and final exam to graduate!

This final Module is comprised of all Practical Exercise assignments to be performed with an FDN Mentor and the Written and Verbal Final Exams.  More details and instructions can be found in the course on FDNconnect.
