resbiotic® Launches Gut Health Test In Partnership with Tiny Health: An Advanced At-Home Microbiome Test That Maps What's Really Driving Your Health
The physician-developed microbiome company expands beyond supplements with a precision gut health test — and a personalized roadmap for what to do next
DALLAS, May 22, 2026 /PRNewswire/ -- resbiotic® (res), a leading physician-developed microbiome health company, today announced the launch of the at-home resbiotic Gut Health Test in partnership with Tiny Health, a precision microbiome platform that delivers a comprehensive picture of gut health — and a clear, personalized plan for improving it.
resbiotic Launches Advanced At-Home Gut Health Test, Bringing Research-Level Microbiome Insights Directly to Consumers
The resbiotic Gut Health Test 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 a simple, mess-free at-home stool sample. Results are processed in a CLIA- and CAP-certified laboratory and delivered within 3-4 weeks, along with a personalized gut health report.
Unlike generic wellness screens, the resbiotic Gut Health Test goes deep. 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 organized 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."
Built for Action, Not Just Insight
The resbiotic Gut Health Test is designed not as a standalone curiosity, but as the starting point of a personalized health protocol. Every test includes a personalized report with actionable recommendations, including which resbiotic formulas may be most relevant based on what the data shows.
The test is HSA/FSA eligible, ships directly to the consumer, and requires no clinical visit. Results are delivered through a clear, actionable report with a recommended re-test cadence of every 60 to 90 days to track progress over 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," said 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
The resbiotic Gut Health Test is built on the same evidence-based approach that underpins the company's supplement line. resbiotic's proprietary strains — RSB11®, RSB12®, and RSB13® — emerged from NIH-funded microbiome research, and the company's supplement formulas have been validated in product-level clinical studies. The resbiotic Gut Health Test brings that same scientific rigor to the assessment side, giving consumers access to insights previously available only in research or clinical settings.
Building on the success of its flagship formulas, including resB®, resM®, resW®, resG®, and resO®, the resbiotic Gut Health Test extends the company's Gut-X Axis approach into wellness testing — connecting gut data directly to targeted, evidence-based supplementation.
Key features of the resbiotic Gut Health Test include:
- Shotgun metagenomics sequencing for comprehensive species-level coverage
- CLIA- and CAP-certified laboratory processing
- Results in approximately 3–4 weeks
- Personalized microbiome report including diversity score, inflammation markers, signals of increased intestinal permeability, and keystone bacteria abundance
- HSA/FSA eligible
- Mess-free at-home collection
