Metabolic & Nutrient Testing
Candida, Metabolic & Vitamins Test
Also known as: Organic Acids Test (OAT)
Yeast, bacteria, mitochondrial energy, neurotransmitters, oxalates, and vitamin needs — from one urine sample.
Organic acids are by-products your body — and the microbes in your gut — leave behind as they process food, make energy, and detoxify. Measured in one urine sample, they reveal hidden yeast or bacterial overgrowth, how efficiently your mitochondria produce energy, how you make and break down key brain chemicals, and which vitamins you're functionally short on.
What it measures
- Candida and mold metabolitesElevations may suggest yeast or fungal overgrowth.
Who this is for
Ideal when symptoms span gut, energy, mood, and focus at once — one test that connects the dots.
- Bloating, gas, or burping
- Acid reflux
- Constipation or diarrhea
- Sugar cravings
- Brain fog
- Low mood, anxiety, or irritability
- Fatigue or poor exercise recovery

How we interpret it
We read every panel through a functional lens — optimal reference ranges, ratios, and cross-panel patterns. Results become part of your written Root Cause Report and your personalized 12-week protocol.
OAT findings tell us what to clear before — or alongside — mineral rebalancing, so your body can absorb and hold onto the minerals we replenish.
