Physician-developed microbiome company resbiotic has announced the launch of the Gut Health Test, an at-home, precision microbiome test kit that it says promises to deliver a "comprehensive picture of gut health," as well as recommend a personalised supplement plan for improving results.
The new Gut Health Test has been developed in partnership with Tiny Health
The testing kit uses shotgun metagenomics sequencing — the same gold-standard method used in leading academic and clinical research settings — to generate a detailed analysis of the gut microbiome from an at-home stool sample.
Results are then processed in a CLIA- and CAP-certified laboratory and delivered within 3-4 weeks, along with a personalised gut health report with tailored supplement recommendations.
These recommendations may include which resbiotic formulas could be most relevant based on the data.
The report covers gut microbiome diversity, markers of gut-driven inflammation, indicators of leaky gut, levels of keystone bacteria, including Akkermansia and Bifidobacterium and signals related to metabolic and immune function.
All of the results are organised around resbiotic's proprietary Gut-X Axis framework, which maps how gut health communicates with and influences other body systems.
"Most people dealing with chronic symptoms — bloating, fatigue, brain fog, metabolic challenges — never get an actual look at what's happening in their gut," said Dr C. Vivek Lal, double board-certified physician, CEO and founder of resbiotic.
"The resbiotic Gut Health Test changes that. It gives people the same quality of microbiome data that researchers and clinicians use, paired with a specialist-guided interpretation and a concrete next step."
This is how gut health should work — not guessing, not generic supplements, but knowing.
The test is HSA/FSA eligible, ships directly to the consumer and requires no clinical visit.
Results are delivered in a clear, actionable report, with a recommended retest cadence of every 60 to 90 days to track progress with time.
"The gut microbiome is one of the most important windows into human health and for too long it's been inaccessible to the people who need it most," added Cheryl Sew Hoy, CEO and founder of Tiny Health.
Tiny Health and resbiotic share the same commitment to rigorous science and together, we can give people a real picture of what's happening in their gut and a concrete path to act on it.
"That's how microbiome health moves from the lab into everyday life."
The science behind the test
resbiotic added that the new Gut Health Test is based on the same evidence-based principles as the company's supplements.
Its proprietary strains — RSB11, RSB12 and RSB13 — were developed from NIH-funded microbiome research and their formulas have been validated in clinical studies.
Now, this new test provides consumers with insights into gut health that were previously available only in research or clinical settings.
By extending the Gut-X Axis approach into wellness testing, the resbiotic Gut Health Test connects gut data directly to targeted, evidence-based supplementation — a feature that is particularly relevant in a market where consumers are increasingly seeking science-backed approaches.
