What Is The Gut Microbiome?
The gut microbiome is a community of microbes, including bacteria, fungi and archaea, that resides in our gastrointestinal (GI) tracts. All of these microbes have specific genes unique to their “bodies,” much like each human has a unique set of genes. Scientists call the full collection of genes of all the microbes in a community a microbiome.
Within each human microbiome, all of the different types of microbes interact with each other — and with their environment (like organisms in Earth’s ecosystems).
Scientists know that a normal, balanced microbiome is essential for maintaining human health, and when a significant shift in that balance occurs, it can contribute to health problems and disease.
What Does Gut Microbiome Testing Involve?
Gut testing involves sequencing the genes of the microbes that reside in your GI tract. How does this work? To put it plainly, these tests require a sample of your poop.
No, you don’t have to poop in a cup. But these testing kits do require you to take a swab from your used toilet paper and place the swab with your fecal sample in a tube. You seal the tube and send it to the lab in the packaging they provide. This process differs slightly by the company.
How Long Before I Get Results?
The lab does a human gut microbiome analysis of your sample and sends you results, typically within four to six weeks, but for some companies, results take longer.
Best Gut Microbiome Testing Companies
We ranked companies based on reputation, the reliability of results, the type of information you get in your results, pricing, customer support and other factors.
Viome Review
| #1 |  |
View on Amazon | Visit Website
Viome’s Gut Intelligence Test uses metatranscriptomic analysis to sequence all the RNA in your stool and identify all living gut microorganisms (bacteria, viruses, bacteriophages, archaea, fungi, yeast, parasites, etc.) at a species and strain level. They also measure the metabolites your microbes produce after you’ve eaten.
Results include a detailed breakdown of the microorganisms in your gut and a personalized food, nutrition and lifestyle recommendation to improve your gut and overall health. Viome’s website has detailed result examples to give you an idea of the information you’ll receive. Unlike uBiome and American Gut, Viome doesn’t compare your gut composition with any database, so you won’t know how your gut makeup compares to others.

Thryve Review
| #2 |  |
View on Amazon | Visit Website
Thryve launched its testing service in early 2017 and has had a good track record since its inception. Their gut bacteria test kit sequences 16S rRNA to discover which bacteria live in your gut down to a species level.
Your results include a report of the makeup of your bacterial microbiome, including which healthy bacteria are low and which known pathogens are high. You also get a “wellness score” based on how your results compare to data from the American Gut Project.
Thryve differs from other companies we review here in that you get a personalized daily dietary and supplement recommendations. They no longer sell non-personalized probiotic supplements via their website, but we found some available on Amazon (see pricing section below).

American Gut Review
| #3 |  |
American Gut is a crowd-funded research project co-founded by Dr. Rob Knight, director of the Center for Microbiome Innovation at the University of California, San Diego. Like Thryve, their test kit sequences 16S rRNA — an RNA subunit that’s believed to be helpful in identifying bacteria and archaea.
Your results include a report on which bacteria and archaea are present and how your microbiome compares to others in the project database. They also give you information on how your diet and lifestyle may contribute to the makeup of your microbiome.
They share results anonymously in open repositories with other scientists to help further microbiome research around the world, but they remove any possible personally identifying information of participants.

BIOHM Review
Dr. Mahmoud A. Ghannoum founded BIOHM based on more than 40 years of NIH-backed research into the human microbiome. BIOHM’s gut test sequences the genes of the bacteria and fungi in your gut.
Your results include a profile of your gut makeup and a comparison to normal levels of bacterial strains from the NIH Human Microbiome Project and fungal strains from Case Western Reserve University School of Medicine.
You can also receive diet and lifestyle recommendations from a registered nutritionist for an additional fee. BIOHM also sells their own probiotics, which are engineered to address the critical role fungus plays in digestive health.

uBiome Review
uBiome used to be the top contender for gut microbiome testing. But unfortunately, uBiome is no longer in business. They filed bankruptcy in September of 2019 after undergoing an FBI investigation into their business practices and other problems. Shortly thereafter they closed their doors for good, and sold off their IP (intellectual property, i.e. patents) for 1% of the company’s original value (they were once valued at $600 million by Silicon Valley) at auction to Psomagen1.
How Can I Keep My Gut Healthy?
Check out this brief video for tips on how to keep your gut microbiome healthy, according to an expert at UCLA.
Can Probiotics Help?
If you’re frequently suffering from digestive problems or have a diagnosed condition, the right probiotics can make a difference in improving your gut microbiome. Proceed carefully, however, as there are plenty of products on the market that either don’t work, or are downright detrimental to your health. See if there have been scientific studies done on the product and research the company prior to purchasing. Questions to ask – how long have they been in existence, where are they based, have they been covered by major publications, etc.
Two of the companies we review, BIOHM and Thryve, sell their own engineered probiotics. Another probiotic that has received some acclaim is Restore for Gut Health — you can view a report on them at the NIH. It claims to relieve a host of health issues including heartburn, leaky gut and migraines, as well as soothing gluten intolerance. Read our review of Restore for Gut Health to learn more.
Other At-Home Health Testing Kits
Gut microbiome testing is just one of a handful of at-home DNA tests you can take to discover more about your overall health. If you’re interested in what else you can learn, be sure to read our article on the best DNA testing for health reasons. We include reviews of the most popular health-related DNA tests, including 23andMe, TeloYears and more.
Also, check out our review of Everlywell, a company that offers a wide range of at-home testing kits to check your metabolism, food sensitivities, vitamin and hormone levels and much more.

It looks as though uBiome may have gone under after filing for bankruptcy in September.
Do you know if Viome provides the equivalent to either the Ubiome Excel Spreadsheet Taxonomy list of bacteria and archaea found or the Ubiome Taxonomy Tree found in Ubiome “Advanced” which shows the same data in a tree that can be collapsed or expanded? Does Viome provide this data in any way?
Hi Tom, Great question! Viome provides your data analysis in two ways: 1) 1. Taxonomy Analysis: The organisms ??? who they are, what are they known for, and how active they are in your sample; and 2. Pathway Analysis: Biological pathway activity levels ??? this is what offers insights into what the microbes are actively ???doing.??? The give you a list on their site, but I’m not sure if you can download your results into a spreadsheet or how else they present the data. I’d encourage you to give their customer support a call. Thanks for your question!
