Big 3 Gut Health Test
Three complementary views of digestive health — organisms, their by-products, and food reactions.

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.
Three views of the gut tell us exactly what to clear, what to rebuild, and which foods to pause — so your mineral protocol can work.

Start with the Root-Cause Fit Assessment. Takes about 3–5 minutes. If it looks like we're a good fit, you'll be invited to schedule a 45-minute consultation to discuss your health history, goals, and whether this program is the right next step for you.
