No Regrets!
From the first module I listened and learned from I knew this was the right place for me! As a health and wellness coach I wanted a way to offer testing for my clients! Learning that testing and not guessing is the motto at FDN! I not only learned the the why but the why and what to do for my clients! Quality thru and thru from the material, to the support and the likeminded people I met. Get started today, you won’t regret it for a second!

Simply the best
Simply the best, attention to detail, and always updating key information. Attention to detail and caring for FDN clients is the blueprint for how we all should care for our clients.

Certification Far Exceeded My Expectations Plus Continued Education Opportunities
The FDN Certification was everything I didn't know I needed. I set out to get a certification to further my work as a practitioner and I got so much more than I could have imagined, including a supportive community, continuous learning opportunities, and the knowledge and tools to truly make a difference in the lives of others on their health rebuilding journeys. I would recommend FDN time and time again to those who are looking to get into or further their career in the health space.

Grateful for the FDN Certification Program & Membership
I learned about the FDN program several years ago, during a time when I was struggling with many unexplained physical and mental health issues. I had seen many doctors and tried a lot of things, but I was not getting enough relief. I liked the FDN concept of investigating the actual underlying reasons why I wasn't feeling great so that I could do something about it. By completing the FDN course and gaining access to functional lab work, I was able to identify the missing pieces and help myself and my family members to overcome different health challenges. I do not want others to struggle for as long as I did, so I started my own health coaching business. I now help children and adults naturally improve their mood, focus, and other brain-related problems, so that they can finally feel great, inside and out. The FDN staff and community have always been positive and helpful when I need advice. I'm grateful for my improved health and for the career opportunities that the FDN certification course has provided me.

FDN will change your life and allow you to help others do the same!
I considered many options when I was looking to get certified in health coaching/functional wellness and I'm so glad I chose FDN. As a former educator I can say that I'm truly impressed with the content format, multi-modal delivery and support I had every step of the way through the course. Plus the opportunity to participate in the same functional labs I was learning about helped me not only better understand the material, but also helped me radically improve my own health. The knowledge and tools I acquired have allowed me to feel confident working with complex clients right out of the gate. Plus, as a practicing FDN there are ongoing learning opportunities and a supportive community. If you are considering FDN my advice is "go for it," you won't be disappointed!

Loved FDN
FDN is a comprehensive program that delivers high value, a beautiful community, ongoing extensive training, and amazing support. I highly recommend it to any person or practitioner who wants to gain the knowledge of how to help people with solutions that actually work.

FDN shifted my paradigm on health
Functional Diagnostic Nutrition shifted my paradigm on what health means! Growing up I have always believed that Western Medicine knew everything and that everything outside of it was voodoo. But as I got older and started hearing about how much that system failed people, I began to look elsewhere. I found the Health Detective Podcast, and my world shifted! The stories, what seemed to be miracles, inspired me and gave me hope that I could help others heal as well. The course is absolutely brilliant, and I love that it's self-paced. I wish there were more practical work, or "homework" to guided our learning throughout the modules. Like for every module, have a small assignment or worksheet to fill out 🙂

FDN's Training and Mentors
When I went thru the FDN course it was a place to be able to learn, grow and connect with like minded people. We became a community. I loved the knowledge, skills, and training that I received. The best part was being mentored by Tess Hanke and Brandon Molle. They were inspiring, kind, helpful and knowledgeable willing to help bring out the Health Coach in me.... I loved being connected with people of this caliber...

This program has been amazing!!
This program has been amazing! I loved that it was self paced and had mentor sessions! I really appreciated the hands on application with self testing and practicals. I just graduated and already have my first couple clients! They are complex cases and I feel confident I can truly help them!

Changed the trajectory of my health, career and community
FDN has made all of the difference in my health, my career and my community. First and foremost, FDN gave me a repeatable process to find solutions to my health and to benefit my clients. We have so many tools and resources provided. As a graduate of the course, I continue to receive benefits. The extra training, the "unmasked" guest speakers, the weekly calls and recordings available, Affiliate program (amazing platform for communicating with colleagues and a place to get more support), and there is so much more. During the course, we get to be our "first client." As part of the enrollment, we receive labs and we get our own results and recommendation calls with a mentor, so we get to experience how to help others first-hand. We learn the flow of the call and then get many opportunities to hone our skill set in the form of practicals- mock clients that we develop a protocol for and are tested on our ability to help. Lastly, but not at all the least important, I have made lifelong friends and formed community with other like-minded people whom I can look to for support and advice in my personal life and professionally. FDN seems to appeal to kind and helpful individuals that really want others to succeed. I think that draw has a lot to do with the nature of our founder, Reed Davis- who also loves to see us all succeed.

FDN has changed my life
FDN has changed my life and has helped me change the lives of others. This program is like no other out there and it works. Getting to know your body is one of the greatest things you can do in the journey of life.

I loved my program!
I loved my program: it was very comprehensive; there was tremendous support and extra learning such as Study Hour and Hot Topics every week. I graduated several weeks ago and feel very confident in sharing my knowledge with my clients. The practicals and reviews with my mentors helped me solidify my knowledge, walk the walk, speak about the screening and the FDN approach confidently and learn even more. My mentors were motivating, friendly and knowledgeable. Not only did I learn to help others stay well naturally, I also learned more about my own health in that I was able to do all the lab screenings on myself first. I loved this hands-on experience! I haven't seen this in any other program that I looked at before deciding to join FDN. I am eager to advance my studies by taking their advanced courses in the future. I also joined AFDNP which is a membership program after we graduate to further our education--not to mention all the other great perks. Thank you again for such a wonderful program. Proud to be a new FDN-P!

Finding FDN was an answer to prayers
Finding FDN was an answer to prayers. I chose to take the course to improve my own health, but along the way I realised I could help so many other people. FDN helped me to find answers to health problems that I had been seeking for years. I have greatly reduced dosages for two prescription medications and am becoming stronger every day. I most recently reviewed an organic acids test with a mentor, and have found, what I hope is, one of the biggest pieces to my health puzzle. Based on what the mentor told me, I am now putting steps in place to improve in this area. The testing is what makes this program unique. It’s amazing to get the big picture view of what your health is and be able to set actionable steps to improve on it. Working with an FDN practitioner allows you to take control of your health.

The FDN-P course is a must for every health practitioner
The FDN-P course is very comprehensive and detailed. I don't think there is a comparable course to ours. Reed and the fantastic team provide a lot of support and help. Once one certifies from the initial course can continue their education and further deepen their knowledge with the advanced courses. I had several health issues which I was able to resolve thanks to what I've learned from the FDN courses. It's an absolute for health practitioners.

Good support and quick
Good support and quick

I have been able to resolve a lot of nagging health issues
I have been able to resolve a lot of physical and even mental issues I have dealt with for years using the methods I learned through FDN. They are a tremendous resource for healthy lifestyle guidance and functional lab analysis. I'm so thankful I found FDN!

An excellent organization with a great community of practitioners
I have been part of the FDN community since 2020 and it has significantly enhanced my technical knowledge and they continue to be one of the best sources of up-to-date information I've seen. Highly recommend for professionals that want to add a holistic perspective to their practice.

The training I needed to heal myself and help my clients
FDN provided me with the foundation I needed to heal myself back in 2014. Now I use FDN principles as the foundation on which I run my gut health clinic. The network of practitioners and support that this community provides is phenomenal. I am so grateful to be a part of this community.

I love FDN!!
I love FDN! The education & support during & after the certification is amazing! I love the Lab aspect of this particular course - it definitely sets us apart! I'm proud to be a Certified FDN-P!!

This course has changed my whole perspective on what it means to be healthy
This course has changed my whole perspective on what it truly takes to be at ones optimal health. I looked at other health coaching courses, but when I came across FDN, I knew this was exactly what I needed. It is definitely in a health coaching league of its own. What sets it apart is that students have access within the course to run functional labs on themselves, so they can identify healing opportunities and come up with comprehensive and highly customized lifestyle plan specific for them, with support and mentorship from an amazing team of course mentors. This was such a game changer for me, as someone who didn't have major health challengers, apart from stubborn weight. It opened my eyes to underlying imbalances and dysfunction in my body that contributed with my weight struggles. I now apply what I've learned inside my own functional health coaching practice, helping my clients find the missing pieces to their own health puzzles, using the FDN approach and philosophy. If you are in search of a top notch health coach certification course, look no further and invest in Functional Diagnostic Nutrition. I highly recommend this program.

The FDN certification program is a game-changer.
The FDN certification program is a game-changer for for anyone looking to advance their health coaching practice or to get into the business. The program is thorough and well-structured, The mentors are also knowledgeable and supportive, and the community of fellow FDNs that also support you along your journey as a trainee is invaluable. What's great about the FDN program is that after you graduate there's plenty of opportunities for continued education through their advanced courses. They also have a "Clinical Advisor" program to help you post-graduation with any questions you might have related to your clients, so you aren't left on your own. There's so much support for trainees and grads! I highly recommend the FDN program to anyone looking to take their health coaching to the next level!

Exceptional program
Exceptional program, especially for the price. I easily would’ve paid $25k for this if I had known what it would do for my health and career. I loved the 1-on-1 support and the focus on training with labs. I ended up having several people I know go through the course, including my girlfriend! I think this program is perfect for anyone who needs to restore their health or wants to make an actual career out of helping people struggling with chronic health conditions. The community afterwards is also amazing. It is nice to be around people who get what it’s like to go through hell and back with your health.

I graduated from FDN seven years ago…
I graduated from FDN seven years ago and I learn something new every day from this amazing group!

A game changer on my health journey!
The FDN training program taught me a whole new way of looking at disease and health. I had been struggling with quite many health issues for years after major surgery. Before FDN I tried a couple of detox programs, made some changes in my diet, and adopted some self-care regimens. I felt better, but I reached a plateau and didn't experience any more improvement. Then I came across the FDN Program, it was definitely a game changer for me! What really sets FDN apart from other nutrition programs, is that the students have the opportunity to run FDN foundational functional labs on their own and get one-on-one coaching and support from the course mentors. That's truly "walk the talk". With the much-needed resources of various assessment tools and the right functional lab work, for the first time, I was able to connect all the dots and find the missing pieces of my health puzzle. FDN is not just "another program". It offers a systematic healing roadmap and corrective strategies. I know exactly what to eat and supplement, how to exercise, how to pivot when things go a bit off. Now I use what I learned from FDN to build my holistic nutrition practice, help my clients understand what is happening in the body, and implement evidence based protocols to support the body's natural ability to heal and function at its potential.

FDN principles just make complete…
FDN principles just make complete sense. For someone who has been very unwell with autoimmune issues and had to figure out the path to wellness through trial and error….FDN is the complete opposite!! Test don’t guess. Get well faster and save thousands of dollars and time, by eliminating the trial and error. Learn healthy lifestyle choices and behaviours to further support maintaining good health.

My experience with FDN was perhaps the…
My experience with FDN was perhaps the best I’ve had in all of my years participating in distance learning. Not only has all of the staff I’ve ever interacted with been courteous and helpful, if I had an issue that needed further attention (like a very specific question or billing inquiry), they always got back to me in a timely manner and resolved the issue for me without delay. FDN is a premiere learning experience and essential growth tool for the functional nutrition community. They have continually delivered top notch, professional, yet down-to-earth insight and education that has put me light years ahead of where I would otherwise be in my own clinical nutrition practice. The program is very clear on the essentials and does so in a concise, focused way, but is also very expansive and always growing. To add to that, the community is massive and the additional tools available to students and graduates are a constant help and clearly geared to revolutionize not only the nutrition industry but to recreate the norm for what clients and patients should expect from a health coach, dietitian or any nutrition professional for that matter. FDN is top shelf in their education, customer service and graduate support.

Excellent and comprehensive training…
Excellent and comprehensive training that continues to stay current amidst ongoing research on the best tools to help people get to the root of their health symptoms. Highly recommended!

FDN taught me what steps I was missing…
FDN taught me what steps I was missing on my own health journey, and in the process of my own healing I learned how to help so many others heal too. Reed and the mentors are fabulous teachers and I continue to learn & grow with them, even after graduating. The FDN community is so supportive and welcoming. I'm so grateful that I invested in myself, and now have the foundation to help others. Thanks FDN!

FDN has been a phenominal experience
FDN has been a phenominal experience. Going through the program taught me how to find hidden stressors and not treat the symptoms. We learned the DRESS model and were trained on many different labs. After graduating, we continue to learn through amazing speakers, webinars and trainings that are offered through FDN. Reed Davis is encouraging, hands on and supportive. There is also a supportive FDN community that is genuine and helpful. I am so thankful i chose FDN.

The custom support through my trianing…
The custom support through my trianing was superb. The quality & amount of continuing education keeps me at the front of my field & career. It's the only thing that's worked to get my health & keep my health.

Amazing program
Amazing program. Every person who ever joined FDN has the highest respect for it and usually recommends it very highly.

Grateful for FDN
Grateful for the customer service and access to the AFDNP community. Grateful for FB lives, case reviews, and all other content. Would love to see more science and research behind the information. Credibility of the information can be questionable at times. Would love to learn more in-depth info about supplements (individual supplements as well as different brands).

FDN empowered me with the knowledge I needed to get my health back
Functional Diagnostic Nutrition (FDN) has been a game-changer in my journey to regain control of my health and destiny. After years of misdiagnoses and feeling overlooked by traditional medical practitioners, FDN has given me the power to be in the driver's seat of my own health. For years, I struggled with health problems, and felt trapped in the Western world of healthcare because I didn't know of another way. Doctors seemed to miss the underlying causes of my health issues, leaving me feeling frustrated and hopeless. But then I discovered FDN, and it was a turning point in my life. What sets FDN apart is its unique approach to health assessment. Functional lab testing provided me with invaluable insights that traditional medical tests had missed. These tests revealed underlying imbalances and dysfunctions in my body that were contributing to my health issues. Armed with this knowledge, I was finally able to address the root causes of my health problems instead of just treating symptoms. The knowledge and training I gained through FDN empowered me to take charge of my own health. I learned how to make targeted lifestyle changes, optimize my nutrition, and implement personalized protocols to support my body's healing processes. I felt like I finally had the tools I needed to take control of my health and well-being. The transformation was truly remarkable. Through FDN, I was able to identify and address specific issues such as gut dysbiosis, hormonal imbalances, and nutrient deficiencies that had been contributing to my declining health. As I implemented the protocols, I started to see significant improvements in my energy levels, digestion, immune function, and overall vitality. But perhaps the most powerful aspect of my experience with FDN was the sense of empowerment and control it gave me. I was no longer at the mercy of misdiagnoses and ineffective treatments. FDN gave me the knowledge and tools to advocate for my own health and make informed decisions about my well-being. Today, I am a living testament to the life-changing power of Functional Diagnostic Nutrition. I am no longer a passive bystander in my own health journey, but an empowered and informed individual who is taking charge of her health destiny. FDN has given me the tools to heal myself, and for that, I am eternally grateful.

I knew I wanted to make an impact…
I knew I wanted to make an impact for people who were struggling with ailments and not getting anywhere in the western medical system. I had been a person suffering from multiple things and didn't get the help I needed from my doctors. I was a self study for many years and knew that there had to be a better way to heal. I couldn't accept the model my doctor was suggesting, and I am so glad I didn't. With FDN I was given/taught the tools and how to obtain true health in a short period of time. The knowledge and support with FDN was great, but what makes them so wonderful is the option for continued support and learning as a graduate. I am grateful to be a part of a family and have the ability to impact so many people in the world.

FDN is a comprehensive program that not…
FDN is a comprehensive program that not only incorporates learning about a functional medicine approach, labs that illuminate healing opportunites, but also the business side of working with clients and how to get your practice active.

FDN changed my life and ability to make an impact!
FDN is one of the most comprehensive and liberating programs I've done. Being an FDN and getting the support I need from the team has been invaluable in my ability to get great outcomes and reach people all over the world with my services.

The world needs more FDN practitioners!
I have enjoyed the entire process of becoming certified as an FDN-P! It taught me entrepreneurship, self motivation, and holistic science. As a registered nurse with my own experience with autoimmune illness, I saw a gap between healing the body versus symptom management. With FDN, I helped myself and I can now help people in a way that I couldn't before to bridge that gap, and I am excited to build my practice!

This program and community has changed…
This program and community has changed my personal health and life for the best along with giving me the tools to build a lucrative business doing what I love while having the freedom to live my best life!
Fantastic, comprehensive course and a team of professionals who really care.
FDN brought me to healing opportunities that doctors never found nor had any clue of finding. The information in this course is mind blowing. I’m glad I was my own advocate in trying to heal my body from what doctors were only making me more sick. I highly recommend this course to anyone
Best functional lab-based course. Very in-depth and rigorous. Way beyond online learning. Work on your own health, case studies, and mock clients with real live professionals. Qualifies you for a board certification. And an active student community. I learned to see relationships in the body vs reducing symptoms to a single issue. That’s the key to knowing how to build health vs just managing your disease.
I had been looking for a long time for a program like this. To me, FDN is a wholistically comprehensive system that teaches you how to get well and how to help others get well. I highly recommend it.
The FDN Certification Course changed my life. After seeing several doctors who told me nothing was wrong with me, I found FDN and decided to take the course so I could be my own best advocate. The course taught me the foundations I needed to get results. By going through the course I discovered several food sensitivities, gut infections, and even an autoimmune disease I had that were contributing to my health challenges that doctors said didn't exist. If you are looking to not only help yourself but also serve others and change their lives, FDN is the education you need.
You can’t go wrong with FDN if you are looking to expand your knowledge on the human body, gain insight into the world of functional lab training and have direct support from the school. No other school does it better! I learned a process to help clients get real healing opportunities and in the process, I did my own healing (part of the tuition includes lab work and Results and Recommendations with the mentors). The support I received as a student was phenomenal (and the support post graduation is amazing, too.) No need to look any further.
FDN has given me the ability to work directly with clients on Disease Prevention and When Possible Reversal. Has opened up a world of Medical Providers that work in unison with me to begin Optimizing their patients 1 at a time.
Awesome health coaching school which helped me understand some basics of lifestyle, gut and hormonal dysfunction which helped myself as well as my clients !
The FDN course is an in-depth course that teaches the nuances of how to proficiently address the various health needs of people. Much of our dysfunction lies in certain areas of the body and this course shows how to recognize the cause of dysfunction and address dysfunction with OTC health-restoring supplementation. For those who care and wish to truly make a difference in the lives of others, this is the path you want to follow. Embark upon this path now! You will always be grateful you did and so will your family, friends, and clients.
Becoming an FDN practitioner has been the best decision of my life. I finally found a career that I love and am passionate about!
FDN is an incredible school and community! The education is beyond and I feel so supported in every way. I feel so prepared to go out and practice on my own knowing they're behind me.
Learning FDN changed my health and changed my life! I have a new career that I love, knowledge to help people, and the energy to work.
Amazing certification! Helped me so much with my health and income :).
The richness of content & access to & training on functional lab testing has opened a wider door to helping people get well! It is beyond exciting & rewarding.
I never felt alone in my training & was always supported every step of the way. I wondered how that would be in a self-paced (mostly) online training program, but the staff is amazing and the community support is second-to-none with an active Facebook group and live zoom study sessions with FDN staff & fellow trainees, etc.
FDN has created a culture of caring and support, where YOU feel front-and-center throughout your training (& beyond in the professional organization AFDNP) with access to the most supportive, understanding & helpful staff I have ever come into contact with (aside from my own ;-)). I truly felt championed & even celebrated each step of the way.
I am in love with this community of educators & healers!
Yes, I was able to support women who have spent most of their lives caring for others and they decided it was time to care for themselves. Most had health issues that we were able to support using functional lab testing to find the missing piece to their health puzzle. Whether it is lacking energy, digestive issues or hormone hell, we worked together to bring the body back to optimum health. I would recommend this program to those who want to bring Hope and Healing to others.
The FDN course brought clarity through extremely well structured and explained modules for everyone to understand, without the need for a medical background.
I learned how to choose the right clients, what will be the structure of the sessions, what laboratory tests I will recommend to each individual but especially how to interpret them, how to make the clinical correlation and how to create the treatment plan based on diet, lifestyle and supplements.
It's the only course in which before I had patients, I was my own patient, I understood better what was going on inside me and what the opportunities for improvement were, then I was able to help others.
It is the only course that has had as stages of examination many clinical cases for a better understanding and application of knowledge.
It is the only course in which mentors have been there, permanently, extremely supportive. I will always be grateful to #ShannonPlummer!
It is the only course in which the founder of the course, Reed Davis, took the time to get to know me personally, to ask me for feedback about the course and where it could improve. But it wasn't just about the course, Reed was interested in my future plans and 3 months after the course I had a check-up related to my practice. Reed pointed out that his door is open whenever I need it! I find the involvement of this man absolutely extraordinary! Thank you, #ReedDavis !
The whole team was prompt and very supportive in various requests! Thank you very much #JoyMoats, thank you very much #DawnHeyn and the whole team involved in this course.
It was an experience that gave me wings, gave me confidence to start the practice and make a major impact in my life! For me it is the most complete course that integrates information from medicine, laboratory tests, nutrition, coaching but especially how to put all this into practice! With gratitude!
What I learned from my test results and my mentors has helped me sleep great again which has been my main complaint for 2 years.
I highly recommend this course to anyone who wants to know exactly what to do to help their clients by testing instead of guessing!
The conventional paradigm is to mask symptoms by using medications, which come with side effects and cause nutritional deficiencies, both of which result in more medications. It’s a vicious cycle that many people don’t even realize they’re on. They also aren’t aware there is a better way of resolving their health issues once and for all.
My FDN certification taught me the principles behind getting to the root cause of problems and conditions. This knowledge is empowering to the person who is suffering because they learn how their lifestyle habits played a significant role in them getting sick. People do better when they know better.
Education and awareness is key to successful client outcomes. I have explained to my clients through the years - that after completing my program - they now have the tools to be in the driver’s seat when it comes to their health. People are able to get well, and most importantly stay well, when they understand the principles of health.
Lifestyle is paramount, but what makes the program shine even more is the ability to incorporate functional lab testing into the mix. This, is not only helpful to me as a functional practitioner, but also gives the client valuable insights into what’s driving their symptoms. It’s so much more then just slapping a bandaid on what hurts.
For anyone who is on the fence about enrolling in the program, I can sincerely attest to the fact that you will learn more than you ever thought possible. Enroll today to change the course of your life, and the people who are waiting for your help because they are out there. People need YOU and what you individually can offer.
