All 11 gut-brain pathways measure in range — the signature of balance.
MAINTAIN

In plain terms

The Resilient pattern is the balanced one. Across all eleven neuroactive pathways we measure, nothing reads as depleted or over-driven — your gut's measured capacity to make and clear the molecules it uses to talk to your brain is broadly in range.

This is the largest group in the cohort, and the most reassuring. The job here isn't to fix a deficit; it's to protect what's already working and tune gently toward how you want to feel.

Because balance is easy to lose, the Resilient phenotype is really about maintenance — keeping the butyrate, serotonin, bile-acid and GABA machinery well fed.

The gut-brain mechanism, in depth

The gut-brain axis is a two-way line. Your gut microbes build and break neuroactive metabolites — butyrate that fuels the gut barrier, bile acids and serotonin that drive motility and mood, GABA that signals calm — and those molecules feed back to the brain through the vagus nerve, the immune system and the bloodstream. The brain answers back, shaping motility, secretion and the microbial niche.

In the Resilient phenotype every arm of that loop is running near its healthy set-point. Butyrate capacity is intact, so the barrier stays fueled; histamine capacity is low, so inflammatory tone stays quiet; GABA and bile-acid signaling sit in range. There is no single lever to pull — the system is self-correcting.

Your measured signature

Measured functional capacity across the 11 gut-brain pathways — read from targeted gene markers in your sequencing data (not inferred from which microbes are present), and CLR-normalized so pathways compare across people. In this phenotype (measured prevalence 26.4%, n = 1,106 of ~4,194 clustered samples) the standout readings are:

Histamine (hdc) ▼ low z = -0.91
Butyrate — buk route ▲ high z = +0.53

z = standard deviations from the cohort mean. These clusters come from the measured capacity alone and are not an artifact of sequencing batch (cluster/run agreement ≈ 0).

Does this sound like you?

Framed as tendencies, not a diagnosis:

In the gut: Digestion is generally regular and predictable; no dominant, persistent gut complaint.

In mood & mind: Mood, focus and sleep feel broadly steady day to day, without a defining neuro pattern.

What the data shows

Across our microbiome dataset (n = 1,112 in this phenotype), these self-reported conditions were more common in this pattern than at baseline — associations, not a diagnosis:

Brain Fog 51% report it OR 1.11 q = 0.40
Depression 38% report it OR 1.12 q = 0.37
Behavior/Sensory issues 32% report it OR 1.16 q = 0.20

Note: in this phenotype no symptom reached FDR significance — the reports above sit at or near the population base rate. That is the core finding of the analysis: symptoms are orthogonal to phenotype. The same complaint (say, anxiety) spreads across all six phenotypes at close to base rate, so a symptom can’t tell you your biology — only the measurement can.

What your formula does

The matched formula’s action is MAINTAIN — protect the balanced axis and tune gently to your goal.

No neuro-active layer — the Steady formula is a light core synbiotic that maintains a balanced axis.

Take it into your own hands

Your phenotype points to specific, self-directed levers — the “be your own biohacker” angle. None of this is medical treatment; it’s how to feed the pathway the measurement flagged:

  • Protect fiber diversity — a wide range of plants keeps butyrate producers fed.
  • Keep fermented foods in rotation to support a resilient community.
  • Guard sleep and regular movement — both stabilize the whole axis.
  • Treat this as maintenance: variety and consistency beat any single 'hack'.

One honest caveat

Your quiz result is a symptom-based pattern, not a verdict — and symptoms are orthogonal to biology, so a measured gut test is what confirms your true phenotype. Everything here is educational and non-therapeutic: formulas potentiate, suppress or support gut-brain pathways; they do not treat, cure or diagnose disease.

Your matched formula

Your result matches the GoodOnes formula built for this gut-brain pattern: Steady. Start there — or confirm your true phenotype first with a measured whole-genome (WGS) test.

Confirm it with a test

This result is a symptom-based read — a strong starting point, not a verdict. Symptoms and your actual gut biology are only loosely linked, so the one way to know your true phenotype is to measure it. A whole-genome (WGS) microbiome test reads the real gut-brain gene signatures shown above — the same pathways (butyrate, GABA, serotonin, bile acids) — from your own sequencing data, so your formula is built on measured capacity, not a guess.
