A Personalized, Data-Driven Approach to Root-Cause Health
If you’ve ever been told to “just eat less and exercise more,” handed a diagnosis like IBS, anxiety, PCOS, or weight-loss resistance, and sent on your way with little clarity—you’re not alone. And more importantly, your body isn’t broken.
The reality is that many health issues are not caused by willpower or discipline. They’re caused by underlying imbalances in the body—nutrient deficiencies, gut dysfunction, hormone disruption, inflammation, and metabolic stress. This is exactly where functional nutrition testing changes everything.
Instead of guessing, functional nutrition uses laboratory testing, biomarkers, and personalized analysis to uncover the root causes behind symptoms and health concerns—so you can take informed, targeted action.

Diagnosis Does Not Equal Resolution
Traditional healthcare excels in emergencies, but often falls short when it comes to chronic health issues. A diagnosis may name the problem, but it rarely explains why it’s happening.
Many people continue to struggle with:
Gut issues like bloating, constipation, diarrhea, or food sensitivities
Fatigue, inflammation, and brain fog
Mood disorders, anxiety, or depression
Hormonal imbalance, thyroid issues, or PCOS
Weight-loss resistance and metabolism dysfunction
Without deeper evaluation, these symptoms are often managed—not resolved.
Functional nutrition testing focuses on function, not just labels. It evaluates how your body systems are working together by analyzing blood, stool, urine, and other samples to identify nutrient deficiencies, hormone imbalances, microbiome disruption, and metabolic stress.
Why Guessing with Diets and Supplements Doesn’t Work
Elimination diets, generic wellness programs, and random supplements often fail because they lack personalization. Guessing which foods, nutrients, or interventions your body needs can lead to frustration, setbacks, and wasted time.
Functional nutrition replaces trial and error with data-driven insights.
Through advanced nutrition testing and lab analysis, we assess:
Vitamins, minerals, and nutrient status
Food intolerances and IgG-mediated sensitivities
Gut health, microbiome balance, and inflammation
Hormones, cortisol patterns, and metabolism
Detox pathways and toxin exposure
This information allows for precision nutrition—a personalized diet, lifestyle, and supplement strategy based on your biology.
The Functional Nutrition Testing Approach
At Harmony with Food, healing follows a structured, evidence-based methodology—not a one-size-fits-all protocol.
Our approach includes:
Assessment & Evaluation – Reviewing symptoms, health history, lifestyle, and lab test results
Targeted Testing – Functional lab testing including microbiome, blood markers, hormones (such as DUTCH testing), and nutrient analysis
Root Cause Identification – Identifying imbalances, deficiencies, inflammation, and dysfunction
Personalized Interventions – Customized diet, supplements, and lifestyle strategies
Gut Repair & Nutrient Repletion – Supporting digestion, absorption, and microbiome balance
Long-Term Optimization & Support – Sustainable changes for lasting well-being
This process supports the body’s natural ability to heal—when given the right information and tools.
Gut Health: The Foundation of Wellness
Your gut is a central control center for overall health. Over 80% of the immune system resides in the gut, and the microbiome plays a critical role in digestion, mood, metabolism, hormone balance, and inflammation.
Functional nutrition testing helps identify:
Microbiome imbalances
Pathogenic or opportunistic bacteria and yeast
Nutrient absorption issues
Gut-brain connections affecting mood and anxiety
Targeted gut interventions—including specific probiotics, prebiotics, postbiotics, and psychobiotics—can lead to meaningful improvements in both physical and mental health.
Real Results from Functional Nutrition Testing
When people stop guessing and start testing, clarity replaces confusion.
Patients often experience:
Resolution of chronic gut symptoms
Improved mood, energy, and mental clarity
Reduced inflammation and skin conditions
Balanced hormones and improved metabolism
Sustainable weight loss without extreme restriction
These changes come from understanding the body’s needs, addressing deficiencies, and supporting function at the root level.
