Functional Gut Health & Digestive Care in St. Johns, FL

Restore digestive balance, heal leaky gut, and resolve chronic bloating through comprehensive microbiome analysis.

Restore Balance from the Inside Out

The gastrointestinal tract is the foundation of total health. It houses 70% of your immune system, produces over 90% of your serotonin, and dictates nutrient absorption across every cell.

When gut integrity is compromised, symptoms extend far beyond stomach discomfort — showing up as systemic inflammation, brain fog, unexplained skin breakouts, autoimmune flare-ups, and severe fatigue.

Rather than masking digestive distress with acid blockers, our functional gastroenterology approach in St. Johns, FL uses advanced stool testing, food reaction panels, and gut lining repair protocols to heal the root cause.

Our Root-Cause Approach

Beyond Symptom Suppression

We test microbiome balance, digestive enzyme output, intestinal permeability (leaky gut), and hidden dysbiosis or yeast overgrowth.

Patient Questions

Frequently Asked Questions

How is functional gut health testing different from standard GI labs?

Standard GI labs focus primarily on structural diseases like ulcers or Crohn's. Functional stool testing evaluates microbiome diversity, enzyme production, inflammation markers, leaky gut antibodies, and hidden bacterial or fungal dysbiosis.

What is Leaky Gut Syndrome?

Leaky gut occurs when the tight junctions of the intestinal lining loosen, allowing undigested food particles and endotoxins into the bloodstream, triggering immune reactions and systemic inflammation.

How long does a gut healing protocol take?

Most gut repair protocols span 8 to 12 weeks, allowing time to eliminate pathogens, soothe intestinal inflammation, and rebuild healthy microbial balance.
