Functional Medicine in Jacksonville, FL — Find the Root Cause

If you’ve been to multiple doctors, received a diagnosis, and yet still don’t feel well — or if you’ve been told your labs are “normal” but something clearly isn’t right — you may be a perfect candidate for functional medicine in Jacksonville, FL.

At Meridian Integrative Wellness, Dr. Nhat Nguyen takes a functional medicine approach that goes far beyond symptom management. Instead of simply treating what’s on the surface, we dig deep into the systems, triggers, and imbalances that are actually driving your health issues — then create a personalized plan to restore true, lasting health.

What Is Functional Medicine?

Functional medicine is a science-based, patient-centered approach to healthcare that seeks to identify and address the root causes of disease rather than just suppressing symptoms. It views the body as an interconnected whole — recognizing that dysfunction in one system almost always affects others.

A functional medicine evaluation typically involves detailed health history, advanced laboratory testing, and lifestyle assessment to build a complete picture of your health. Treatment plans are highly individualized and may include targeted supplementation, dietary interventions, lifestyle modifications, and other natural therapies.

Conditions We Address with Functional Medicine

Advanced Functional Medicine Testing at Meridian

Our Jacksonville functional medicine practice uses comprehensive testing panels that conventional medicine often overlooks, including:

• DUTCH Complete Hormone Test — the most comprehensive dried urine hormone panel available, assessing sex hormones, cortisol patterns, and hormone metabolites
• Organic Acids Test (OAT) — evaluates metabolic function, gut dysbiosis, nutritional status, and neurotransmitter metabolism
• Metabolic Assessment Profile — measures oxidative stress, detoxification capacity, and cellular energy production
• Food Sensitivity Testing — IgG/IgA reactivity panels to identify immune-mediated food reactions
• SIBO / SIFO Breath Testing — diagnoses small intestinal bacterial and fungal overgrowth
• Comprehensive Thyroid Panel — TSH, Free T3, Free T4, Reverse T3, TPO antibodies
• Genetic Testing — MTHFR, COMT, and other SNPs that affect nutrient metabolism and health risk

Functional Medicine + Chiropractic: A Powerful Combination

What makes Meridian Integrative Wellness unique among Jacksonville functional medicine providers is our integration of chiropractic care with functional medicine. The nervous system — optimized through chiropractic — is the master controller of every body system. When the spine is aligned and the nervous system is functioning properly, the body’s ability to respond to functional medicine protocols is dramatically enhanced.

Most functional medicine practitioners don’t address the structural component of health. At Meridian, we treat both the biochemistry and the biomechanics — giving our patients a truly comprehensive path to healing.
