The FDN Certification Course is an open enrollment course which means you get access as soon as you register.  The course is self-paced and modules open up as you complete the previous module.  You can access lessons online 24 hours a day, 7 days a week. 

The FDN Certification course is self-paced and trainees are granted up to one year to complete all course requirements to graduate.   A reasonable time frame to get through the course is about 6-8 months. Therefore, a one-year time limit gives trainees plenty of time to complete their FDN certification. It is up to the trainee and what works with their schedule.  The curriculum provided with the course serves as an outline to complete the course within 6-8 months.  We’re here to help you succeed!

You will receive 5 functional lab screenings as part of your tuition.  There is no cost to you. Personal test results sessions are also included and are considered an important part of becoming a certified FDN.

  1. Salivary Stress and Hormones Panel (checks cortisol, sex hormones, and melatonin)
  2. Dry Urine Metabolic Wellness Profile (assesses digestion/absorption, oxidative stress, and detoxification)
  3. Dry Blood Mucosal Barrier Assessment (assesses gut function)
  4. Pathogen Screening via Stool (screens for gut pathogens)
  5. Metabolic Typing Online assessment available mid-course

Your personal lab screening kits will be shipped to you after you have completed Module 1.

Yes, we have worked hard with our lab partners to make testing available worldwide.  You will still receive 4 lab screenings as part of your tuition and cover the cost of shipping those test kits to you.  You would be responsible for any fees associated with sending your test samples back to the lab(s). If you have any questions related to shipping test kits in your area please contact us at [email protected]

All lessons are pre-recorded online webinars, videos, and audio, with charts, diagrams, and slides that go along with each video.  There are quizzes at the end of the module.  The last quarter of the course is made up of 2 personal results sessions and 6 practical sessions with a mentor to help you put into practice what you have learned.

The FDN Course includes 11 hours of one-on-one mentoring. You get two personal results sessions to review your test results with an FDN mentor. These sessions are meant to be a teaching experience for you to learn what a results session looks like and how you will go over results with a client. Your personal results sessions are recorded so that you can relisten to them anytime. There are 6 “Practical Exercises” with mock-up clients that help you put into practice what you have learned, these sessions are done with a mentor in a role-play scenario. (Following the model we teach). There are resources available to you for additional support from an FDN practitioner should you wish to get more support on your own case.

No. The FDN Course has no pre-requisites and is open to anyone looking to expand upon their current credentials, change careers and work on their own personal health.

No. Regardless of where you live or your background, you will not be practicing medicine unless you are licensed to do so. As FDN Practitioners we are positioned to educate clients on how to improve their health, period. We don’t diagnose or treat disease. The health building model we teach is completely different from the disease care model. Not only do we teach you how to provide FDN services the correct way, but we also give you the intake/onboarding forms you need to practice it. (Applies to licensed providers who think that FDN may be out of their scope of practice).

The FDN Course provides the latest up-to-date training available as we continually update the lessons. The FDN Course is an immersion process in which you work on yourself as you learn to work on others. The personal mentorship is unparalleled as you will receive hours of guidance. The FDN Course delivers education, materials, tools, personal mentorship, and a robust and active post-graduate community that provides ongoing training and support.  We are dedicated to helping our practitioners succeed. 

We have found that anyone can run labs. It’s knowing which lab to run, how to interpret the results, what to do with the data that is relevant to your individual client that is most important. We teach you a step-by-step process that will give you the confidence to help more people and charge more for your services. We fear that other courses teach you how to treat the test results instead of the person.

Course founder Reed Davis provides you with every tool, every protocol, and every piece of patient education material he developed in his 12 years of practice. His methods and materials are not available anywhere else. When you graduate you receive ongoing access to the course materials, including updates as science changes in our industry.

Yes, we provide an attractive, digital certificate of completion, signed by the founder of FDN, Reed Davis, suitable for framing and display, and is easily distributed online and via email.

Yes, unlicensed practitioners may access lab testing via our Medical Director Program (MDP). What is the FDN Medical Director Program (MDP)?
The Medical Director Program is a full-service lab-testing and clinical support program created so that unlicensed FDN Practitioners can practice FDN and access lab testing/screenings for themselves and their clients.

No. We teach you what we personally prefer and what we find works well. However, you should feel free to find equivalents and use them at your discretion.

Not necessarily. In every instance, the products we recommend in the FDN Course are safe and natural, and available over-the-counter in the U.S. Most US companies will ship products out of the US, however, you should check with local Customs authorities before ordering supplements from the U.S. While we have made reasonable efforts to identify locally available products in the UK, Canada, Australia, and NZ, we have no control over that availability or your ability to purchase them. Please note that FDN Inc. does not sell or distribute supplements and all transactions are between you and the supplement companies you choose to use.

Yes, we provide recommendations for liability insurance that is available worldwide.

Yes, you can integrate FDN lab screenings into your practice and use them with your clients. Unless you are a licensed practitioner, you will need to complete the course before being able to access testing for your clients.

Yes! We provide an example of pricing structure in the course materials.  Additional training and support are available post-graduation as part of our graduate association. 

The rule of thumb is around $200 per hour. Once you get your arms around the work and what it can do for a client, you can decide how much you want to charge. Keep in mind that the founder of FDN has operated a very successful practice for many years and shares his methods throughout the course. It’s likely you will be able to make more money than you did before you took the FDN Course. Whether you do or not is up to you, as you must go through a learning curve to charge more than you are used to charging for current services that you offer. You will begin to attract many new clients that need your help. Very often they are much less concerned with the cost than you are. We will help you to avoid selling yourself short.

Absolutely. One of the most frequent comments we receive is that FDN trainees are very happy with the results they get from doing the lab work and personal consultation on themselves. It’s a personal journey and we expect FDNs to “walk the talk”.

Yes. There are several resources available to you post-graduation. We offer a robust post-graduate low-cost membership that includes an active community of practitioners, ongoing training webinars, and frequent case study reviews.  We also offer clinical support through our Medical Director Program with one of our FDN Clinical Advisors.

Yes. The FDN course is approved for PDC’s from the following organizations: NCCAOM, NANP, The Chek Institute, and NBHWC. If you have an accrediting or governing body for which you’d like the FDN course to be approved, please supply us with the proper application form. Many organizations will also consider our course for approval upon petition. We can supply you with a course outline/list of Instructor credentials which you can submit to your organization to see if the course will meet their criteria for approval.

Yes. Recertification assures the public that anyone claiming to be practicing FDN is doing so according to methods and procedures taught in the FDN Certification Course or recognized by AFDNP Inc. as an acceptable FDN health coaching practice. We require all FDN practitioners to recertify every two years by completing 6 hours of Professional Development Credits and submitting a $99 fee.
