Gut Biome Analysis
A microbiome analysis profiling your gut bacteria to inform your plan.
- Microbial diversity and composition, as context for energy, weight and metabolic goals
- A baseline before a sustained dietary change, with a view to re-testing later
Context, not diagnosis. It does not measure digestion, absorption or gut inflammation — if you have persistent gut symptoms, the fuller panel is the right test.

What it measures
The gut microbiome has become one of the most talked-about areas in health, and for good reason — the research connecting gut bacteria to metabolism, immune function, mood and energy is genuinely interesting.
It has also outrun itself commercially. There's a sizeable industry selling microbiome tests that promise personalized answers the science can't yet deliver, usually accompanied by a supplement recommendation.
We offer microbiome analysis because in the right context it's useful. This page is about what that context is, and equally about when it isn't worth your money.
A gut microbiome analysis sequences the bacterial DNA in a stool sample to profile which organisms are present and in what relative proportions. That gives you a picture of diversity — how varied your microbial community is, which is one of the more consistently meaningful markers in the research; composition — which bacterial groups dominate and which are underrepresented; and functional potential — inferences about what those populations may be capable of doing, such as producing short-chain fatty acids. What it produces is a snapshot of your microbial community at one point in time.
How it works here
Every plan follows one path. Each step feeds the next. See the Lab Testing approach.
- 01
Measure
We baseline your labs, history, and goals.
- 02
Plan
A clinician decides whether this fits — and what else might serve you.
- 03
Act
If appropriate, you start with clear guidance and high-touch support.
- 04
Track
We monitor how you respond on a defined cadence.
- 05
Adjust
Protocols are refined over time. Guided care, not a kit in the mail.
Which gut panel is right for you
ACT 2 offers two gut tests, and they answer different questions.
The honest summary: if you have actual gut symptoms, skip this one and go straight to GI Effects + Microbiomix. The digestion and inflammation markers in the fuller panel are the clinically established part, and they're what will actually explain what's happening. Microbiome composition alone rarely tells you what to do about symptoms.
This panel makes more sense when you don't have significant symptoms, and you're exploring how gut health connects to broader goals like energy, weight and metabolic health.
What it can't tell you
It cannot diagnose IBS, IBD, celiac disease or any other gastrointestinal condition. It cannot detect cancer or replace a colonoscopy. It cannot identify food intolerances or allergies. It cannot tell you which probiotic you need — that claim runs well ahead of the evidence. And it cannot detect gut inflammation or digestive dysfunction; that is what the fuller panel is for.
If you have persistent or concerning gut symptoms — bleeding, unexplained weight loss, a marked change in bowel habit, or pain that's new — those need proper medical evaluation, not a microbiome kit.
Delivery
An at-home collection kit; results come back in a written report.
When it's genuinely worth it
This panel earns its place when you're working on metabolic health and want to understand one more input alongside your weight management plan; when energy and general wellbeing are the focus and your standard labs are unremarkable; when you want a baseline before making a sustained dietary change, with a view to re-testing later; or when you're curious and have already handled the fundamentals — a legitimate reason, provided expectations are set. When it's usually not worth it: you have significant gut symptoms, in which case use the fuller panel; you haven't had standard blood work yet; or you're hoping the result will tell you exactly what to eat. It won't, at least not yet.

Gut Biome Analysis, question by question
The specific questions people bring to this treatment, each answered on its own page and reviewed the same way this one is.
The Microbiome and Menopause: The Estrobolome
Gut bacteria recycle estrogen, and the community changes at menopause. What the estrobolome is, what a sequencing test sees, and the limits of acting.
ReadGLP-1s and the Gut Microbiome
GLP-1 medications change what you eat, how fast it moves and — studies suggest — which bacteria live on it. What is known, and when to run a gut test.

Every gut test leads with a diversity number and a color. What alpha and beta diversity measure, why that is not a diagnosis, and how to read a report.

An honest word on the evidence
Microbiome science is moving quickly and is nowhere near settled. What's reasonably well supported: that microbial diversity tends to associate with better health outcomes; that diet meaningfully shapes the microbiome; and that the gut is involved in metabolic and immune function in ways that matter. What isn't: what an “optimal” microbiome looks like for a specific individual. There is no established reference range in the sense that there is for, say, vitamin D. Two healthy people can have substantially different microbial profiles, and the link between a given bacterial finding and a specific intervention is, in most cases, considerably weaker than test reports imply. Results also shift — your microbiome changes with diet, travel, illness and medication, particularly antibiotics — so a snapshot is a snapshot. Our position: this is context, not diagnosis. It's one input among several, and it belongs in a conversation with someone who will tell you when a finding doesn't warrant action. A test report that hands you a list of supplements matched to your bacterial profile is selling you something the evidence doesn't yet support.

Frequently asked questions
The composition and diversity of the bacteria in your gut, used to inform digestive and metabolic decisions. It profiles which organisms are present and in what proportions — not how well your digestion is working, which is a different measurement.
It depends on your question. For understanding how gut health connects to energy, weight and metabolism, it adds useful context. For explaining actual gut symptoms, the fuller GI Effects + Microbiomix panel is the better choice because it measures digestion and inflammation directly.
No. It can't diagnose IBS, inflammatory bowel disease, celiac disease or any other gastrointestinal condition, and it doesn't replace a colonoscopy or medical evaluation of persistent symptoms.
No, and be wary of any test that claims otherwise. Matching a specific probiotic to a specific bacterial profile is not something the current evidence supports, however confidently a report presents it.
An at-home kit with a stool sample, mailed to the lab. Straightforward, and no clinic visit required.
Considerably. Diet, travel, illness and especially antibiotics all shift it. That's why a result is a snapshot rather than a fixed characteristic, and why timing relative to recent antibiotics matters for interpretation.
If you have persistent gut symptoms, the fuller panel — its digestion and inflammation markers are the clinically established part. If you're asymptomatic and exploring gut health in relation to energy or metabolism, this one is the more proportionate starting point.
Your results come back in a written report. If they bear on a treatment you start with ACT 2, your prescribing clinician reviews them alongside your symptoms, history and standard labs. Some findings warrant action; many don't, and being told which is which is most of the value.
