Our editors have personally used and researched lots of health diagnostics. These are our picks for microbiome tests with reliable, science-backed insights and user-friendly reports to help you understand and support your gut health.
At least 20% of Americans struggle with diagnosed digestive issues like IBS or chronic constipation, according to the NIH. But many others still experience countless digestive abnormalities like gas, bloating, and abdominal pain on the regular. So if this is you, you’re in good company.
But what if your constant bloating could be connected to other symptoms, like brain fog, poor sleep quality, or skin irritation? After all, the mind-gut connection is well-documented. It turns out your gut health can influence so much more than your moods—your gut also regulates your immune system, metabolizes hormones, produces key neurotransmitters, and more.
Enter at-home gut microbiome testing. Still an emerging science, these over-the-counter tests show promise in helping you unlock the secrets of your gut microbiome — and how it might be affecting your whole-body health. So if you’re dealing with digestion abnormalities or even other unexplained symptoms like fatigue, skin conditions, mood swings, or sleep issues that you just can’t get to the bottom of, it might be worth looking into a microbiome test kit.
How do at-home gut microbiome tests work?
At-home gut microbiome tests work by analyzing a sample that you send in. This is typically a stool sample (the test gives you detailed instructions on how to provide the sample), and after it’s analyzed in a lab, you’ll receive digital results usually in a few weeks. These results give you insights into your gut health.
Depending on the brand, you’ll find out about your good and bad bacteria content, anything you might be deficient in, biological age, and plenty of other biomarkers like inflammation, immune health, sleep health, and risk factors for certain diseases. And the best part is the personalized insights—all the microbiome tests below give you personalized action items like foods to prioritize or avoid, supplements to take, or lifestyle factors to change.
Our criteria:
After reviewing, researching, corresponding with brands, and combing through customer reviews, our editors have chosen the best microbiome tests to support your gut reset and overall wellbeing. We update this list regularly as emerging favorites, and all of our picks are evaluated to meet the following criteria.
CLINICIAN/SCIENCE-BACKED | Microbiome tests should provide clinically relevant insights that are meaningful and actionable. We’ve chosen brands that are grounded in research and have thoughtful, experienced clinicians involved.
USER-FRIENDLY & SUPPORTIVE | These brands are clear about what’s tested, how results are generated, and what to do next. We prioritized options that have intuitive dashboards, personalized recommendations, offer expert support, and provide follow-up resources, too.

1. Viome
Best For | Supplementation & lifestyle recommendations
Features | App integration, customized supplements, 50+ health markers, personalized food recommendations
Accepts Insurance | N
FSA/HSA Eligible | Y
Prices starting at | $199/month
Our editor recently tried out Viome’s Full Body Intelligence Kit to look for answers to her husband’s digestive issues, and was rewarded with some valuable insights. The brand makes both a Gut Intelligence test and an Oral Intelligence test, and you can also grab both of them with the Full Body kit. The easy, at-home collection of blood, stool, and saliva gets you digital test results in two to three weeks, and helps you shine a light on all sorts of issues—from digestive problems to fatigue, skin irritation, gum sensitivity, and poor sleep. You’ll receive over 50 health scores for markers like biological age, inflammation response, and immune system health, along with a recommended list of foods to eat or avoid. Note that Viome costs $199 per month, and they require a four-month commitment when you first order the test—that price also includes customized supplements delivered monthly.

Best for | Gut health test
Tests for | Candida, parasites, and bacteria associated with inflammation

Tiny Health offers insights into your gut health with its mess-free microbiome test. This approach to food sensitivity looks at the presence of candida, parasites, and/or bacteria associated with inflammation to help you see if you have any infections or signs of leaky gut. Tiny Health also gives insights for steps and personalized tips to help your gut health based on your results. The sample requires you to swab a sample of your stool off of a tissue, which only takes about 5 minutes. Then, you get results within approximately 3-4 weeks. Tiny Health also has gut health tests for children and babies. For all tests, Tiny Health offers a free personalized review session with a microbiome specialist. While they are not intended to diagnose, they can help you learn more about the microbes in your body and give you a jumping off point for discussing with your physician. Tiny Health works with CLIA-certified laboratories, is HIPAA compliant, and is CAP accredited, too. They accept HSA/FSA.

A favorite brand here at Good Gear for their rigorously tested, athlete-focused supplements, Thorne makes a Gut Health Test that’s super easy to do at home. You’ll receive a detailed analysis regarding your GI and overall health, making this test great for folks experiencing a range of issues—from regular constipation or heartburn to excess gas, bloating, or even fatigue or brain fog. Thorne uses a patent-pending wipe technology that makes the at-home sample collection simple and user-friendly. Once you’ve sent your wipe back to the lab, you’ll have results within five to six weeks, all presented on an easy-to-read online dashboard and done by an independent physician. Results show things like good and bad bacteria levels, micronutrients and fatty acids present, and intestinal permeability, and you’ll even receive scores for digestion, inflammation, and nervous system imbalance, along with recommendations for dietary, supplement, and lifestyle changes.

Features | Probiotic recommendations, monthly subscriptions
Accepts Insurance | N
FSA/HSA Eligible | Y
Prices starting at | $230
Ombre’s Gut Microbiome Health Test provides you with easy-to-understand, actionable insights into your gut health. They focus on testing for bacteria specifically, measuring levels of thousands of types of bacteria, both good and bad, to give you a comprehensive look at your gut microbiome. They’ll recommend targeted probiotics based on your results, and they make it a breeze to see if the supplements are actually working—if you subscribe to receive tests monthly, they’re $150 each rather than $230, and you’ll be able to easily track your gut health changes over time. The quick sample collection is done at home, and you’ll receive your microbiome results in just two or three weeks, along with diet and lifestyle recommendations. And their recommended probiotic supplements target what your gut health is most affected by, like metabolism, immunity, or even mood.
Customer Review | “I found the test very informative with a lot of useful information. Looking forward to repeating the test to see if the changes have improved my scores. The probiotic has been very helpful.” – Jean Gilbert (Read more reviews.)
5. Zoe
Best For | An easy-to-use meal tracking app
Features | In-app results, personalized recommendations, diet tracking app
Accepts Insurance | N
FSA/HSA Eligible | N
Prices starting at | $TBD
Zoe’s gut health test comes combined with an app that helps you track your food and receive personalized food advice. But the test kit and app are currently going through a relaunch and haven’t quite been released yet, so you can sign up on their website to be among the first to hear about the official new launch. The microbiome test kit, like most others on the market, will have you do an at-home stool sample that you send to their lab for analysis. The app, which you must have a subscription for, then shows you your comprehensive gut health analysis and personalized food recommendations. The app goes a step further, too, making it a breeze to track your meals (their focus is on plant diversity) to make sure you’re hitting benchmarks — and the app will even tell you the health of a meal with a quick photograph.
Customer Review | “I feel much better. I’ve been extremely happy with it; I physically feel differently and I empirically have data that shows I’m improving.” – Travis (Read more reviews.)
6. Superpower
Best For | Blood test with a microbiome test add-on

Accepts Insurance | N
FSA/HSA Eligible | Y
Prices starting at | $199
Developed by MDs and top longevity clinicians, Superpower gives you a comprehensive, actionable look at your health with over a hundred different biomarkers. It starts with a blood test that you can have done at any of their 2,000+ partner labs. While the test measures some things you’d expect from typical bloodwork at your PCP like cholesterol and vitamin D, it goes beyond with easy-to-understand info like your biological age, and risk factors for diabetes and heart disease. You’ll also receive an actionable plan with diet and lifestyle recommendations, and concierge messaging with their experts for specific questions. Membership costs $17 per month, billed annually (so $199 a year) and includes one blood test a year, and you can add on a specific gut microbiome test kit if you want additional insights into your gut health.
Customer Review | “My Superpower advisor goes, are you like, really low energy? And I was like, yes. Turns out I’m deficient in five areas that contribute to my overall energy. I feel so validated… it’s not just like, oh, I burnt out. I’m feeling like I got answers and I’m hopeful.” – Victoria Brown (Read more reviews.)
7. Generation Lab
Best For | A science-backed look at your biological age
Features | Easy at-home blood test, clinician consultation
Accepts Insurance | N
FSA/HSA Eligible | N
Prices starting at | $499
Generation Lab’s SystemAge is less of a microbiome-specific test and more of a comprehensive look at your body’s biological age — and how to lower it. It starts with a blood test that you can perform yourself at home. You’ll then receive an action plan and a consultation with a clinician, similar to the other tests on this list. But unlike the other tests, SystemAge measures 460 (!) biomarkers for your 19 different organ systems, giving both a close-up view and a zoomed-out look at your body’s comprehensive health. It uses a DNA methylation noise detector to measure your aging factors, stressors, and trajectory at the cellular level, based on groundbreaking research by Dr. Irina Conboy, PhD, who has spent over 20 years decoding the biology of aging. The result is more clarity over your aging process, and you can subscribe to save 10% if you want to test every few months and track your progress.
Customer Review | “As a busy mom at 35, staying healthy is crucial for both me and my family. Finding the right diet has been a challenge. But Generation Lab is a game changer! It’s giving me clear insights and control over my health. Thrilled to have found it!” – Jing (Read more reviews.)
