The only functional lab methodology proven effective over 15 years of clinical practice
Join 5,000+ practitioners who’ve escaped the trial-and-error cycle to build thriving 6 and 7-figure practices using systematic FDN Methodology
Even with the best intentions, most practitioners remain stuck in the same cycle their clients experience…
The Symptom-Chasing Game Running labs based on symptoms (“sounds like thyroid”) creates an endless cycle of test-treat-test-treat without addressing enough underlying causes to completely resolve the problem. You’re playing medical detective without using the most comprehensive investigation
Inconsistent Client Outcomes Generic protocols work for some clients but fail others, leaving you and your client questioning your expertise. Without a systematic approach, you’re essentially experimenting on every client.
Practitioner Burnout Generating protocols for every case is exhausting and unsustainable. You need a repeatable system that consistently delivers positive results so you can focus on living a more balanced life.
After watching countless clients cycle through 4, 5, 6+ practitioners with no lasting results, Reed Davis made a commitment: “I will be the last practitioner they ever need to see.”
Through 10 years of clinical practice, reviewing thousands of labs for thousands of people, and meticulous observation of patient outcomes, Reed discovered the missing piece in functional health.
“The breakthrough wasn’t finding THE root cause—it was systematically identifying MULTIPLE healing opportunities and applying health building principles to every cell, tissue and organ — simultaneously.
~ Reed Davis, FDN Founder
The Last Practitioner
Our H.I.D.D.E.N system reveals dysfunction across hormone, immune, digestion, detoxification, energy production, and nervous systems. No more guessing which tests to order – you get the complete metabolic picture every time.
Like a detective collecting ALL available evidence before drawing conclusions, we gather comprehensive data to identify multiple healing opportunities simultaneously, not just isolated symptoms.
Whether it’s autoimmune conditions, gut issues, or hormonal imbalances – the FDN Methodology works because we address metabolic dysfunction at multiple sources, not just downstream effects.
Our Medical Director Program provides you access to 70+ functional labs, transforming your practice capabilities immediately – no license required.
Our proven 5-lab framework reveals the complete picture of metabolic dysfunction.
Instead of chasing symptoms, we systematically evaluate major body systems using the FDN Methodology to identify where dysfunction creates downstream effects throughout the body.
Once H.I.D.D.E.N healing opportunities are identified, applying the health building principles inherent in the D.R.E.S.S. for Health Success program produces the results you and your clients are looking for.
This signature framework transforms lab data into personalized protocols that reliably and repeatedly produce successful outcomes, regardless of your client’s health challenges.
“The FDN System consistently outperforms any other programs we are aware of.” – Reed Davis
Not just sleep optimization but a holistic approach to total recovery strategies tailored to individual circadian rhythm and cortisol patterns and balances the hormone and autonomic nervous systems.
Exercise programs are designed to meet the needs of each client based on their current health status, age and conditioning, then revised & updated as conditioning improves, often leading to surprisingly superior results, even surpassing clients’ highest expectations.
Stress in all its forms is complex and multi-faceted but not impossible to sort out, even when it comes to well-hidden and deep-rooted sources. Stressors ranging from physical ailments to mental-emotional and psycho-spirtual distress to environmental and bio-chemical challenges add up over time and have down-stream effects that contribute to Metabolic Chaos®.
Not only does each causal factor have a negative effect, they all affect each other in ways that can’t be singly measured. Our D.R.E.S.S protocol has a positive effect on every cell, tissue, organ and system (the entire organism) simultaneously.
Used not to treat the disease but to Substitute for what’s missing in today’s food, Support weak systems, Stimulate areas as needed and Self-treat when all-natural, drug-free protocols are appropriate.
Supplement Recommendations are based on specific deficiencies and dysfunction – guided by lab data and client complaints, not just guesswork.
FDN is a proven step-by-step system that identifies obstacles to healing and helps clients creatively overcome them, eventually unveiling the core dysfunctions and underlying causes.
The Power of Integration D.R.E.S.S. protocols affect every cell, tissue, organ, and system simultaneously. This systematic approach is why our graduates achieve transformative results when others see only marginal improvements.
