What’s in your gut? Scientific advances in the last decade show that a diverse host of microorganisms that live in our digestive systems serve both good and bad roles in our overall health.  Gut microbiome testing is one way to find out what’s right for you.

If you suffer from chronic stomach problems, are curious about your gut makeup, or want to contribute to ongoing gut-related DNA research, read our microbiome testing reviews to learn more.

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. 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 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 based on 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 4 to 6 weeks, but results take longer for some companies.

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.

Winner: Viome Review

View on Amazon

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. However, unlike other companies, Viome doesn’t compare your gut composition with a database, so you won’t know how your gut makeup compares to others.

ProsCons
Analyzes more types of microorganisms than other testsThe website doesn’t explain how you collect your sample
Nationally-accredited CLIA labDoesn’t have its own database for comparison (or compare against other databases)
Get results within 3-4 weeksSome users complain that they received generic (common sense) advice that isn’t unique
Customers report good experiences with supportNo access to your raw data
Some customers feel they’ve been able to improve their digestion, sleep, and mood as well as lower inflammation
Re-test at a steep discount whenever you’d like
Scientific Advisory Board includes leading doctors, scientists, and experts from Harvard, UCLA, and more

What Happened To uBiome?

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 after that, 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 Psomagen.

How Can I Keep My Gut Healthy?

According to an expert at UCLA, check out this brief video for tips on how to keep your gut microbiome healthy.

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 doesn’t work or are downright detrimental to your health. See if there have been scientific studies done on the kits and research the company before purchasing. Questions to ask – how long have they been in existence, where are they based, 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 ION Gut Health to learn more.
