Test Your Microbiome for Better Gut Health

Constant bloating, irregular digestion, or unexplained lack of energy? If this sounds familiar, you're not alone. The answer to these complaints could be hidden deep inside you—more precisely, in your gut. A microbiome test can help you finally gain clarity by showing you what is really going on in your body.

Finally Understand What's Going On in Your Gut

Don't think of your gut as merely a digestive organ. See it as a vibrant, complex ecosystem. Trillions of microorganisms live here—mainly bacteria, but also viruses and fungi—which together form your very own microbiome. This vast network is much more than a digestive aid; it plays a central role in your overall health.

The exact composition of the tiny inhabitants of your gut has a major influence on how well your body absorbs nutrients, how strong your immune system is, and even how you feel. When this finely tuned balance becomes disrupted—known as dysbiosis—it can manifest through a wide variety of symptoms.

More Than Just Stomachaches

A disrupted microbiome is no longer associated only with classic digestive problems. Research in recent years has shown increasingly clearly how far-reaching the effects can really be.

• Immune system: Incredible but true: About 70% to 80% of your immune cells are located in your gut. A healthy gut flora trains your immune system and helps it distinguish friend from foe.
• Mood and mental health: Your gut and brain are in constant communication via the so-called gut-brain axis. Certain bacteria even produce neurotransmitters such as serotonin, which can directly affect your mood.
• Skin: Skin problems such as acne, rosacea, or eczema can also be a reflection of your gut. Inflammatory processes that begin in the gut often show up on the skin as well.

A microbiome test essentially provides you with a data-based snapshot of this inner ecosystem. Instead of fumbling in the dark and trying different diets or supplements on a whim, you get a concrete analysis. You can see in black and white which bacterial strains predominate in your gut, which may be missing, and where an imbalance exists.

A test is often the first step toward moving from simply managing symptoms to specifically addressing their causes. It gives you the control and knowledge to finally make informed decisions about your health.

The following table shows which symptoms are often associated with an imbalanced gut flora and how a test can provide clarity.

Typical signs of an imbalanced microbiome

Symptom	Possible connection to the gut	What a test reveals
Chronic bloating and gas	Impaired fermentation caused by unbalanced bacterial cultures.	Overgrowth of certain gas-producing bacteria or a lack of strains that support digestion.
Irregular bowel movements	Impaired gut motility, often influenced by the gut flora.	An imbalance that can lead to constipation (e.g., methane producers) or diarrhea.
Constant fatigue	Poor nutrient absorption and chronic low-grade inflammation.	A lack of bacteria that produce important vitamins (e.g., B vitamins).
Skin problems (acne, eczema)	“Leaky gut”—a permeable gut barrier that promotes inflammation.	Signs of a weakened gut barrier and markers of inflammation.
Sugar cravings	Certain bacteria and yeasts “feed” on sugar and can trigger cravings.	Overgrowth of yeasts (e.g., Candida) or sugar-loving bacteria.

This list is, of course, not exhaustive, but it gives a good impression of how closely your gut health is linked to your overall well-being.

In Germany, although many people are familiar with the term "gut flora", the broader concept of the microbiome and its true importance for health have not yet fully entered the public consciousness. According to an Ipsos survey conducted in eleven countries, Germans were familiar with the word "flora", but less so with the term "microbiome".

These insights are the foundation for making targeted changes. Whether through an adjusted diet, the right choice of prebiotics and probiotics, or lifestyle changes—a test points you in the right direction.

What a home gut test really involves

The thought of collecting a stool sample initially makes many people feel uncomfortable. It sounds complicated, perhaps even a little unpleasant. But nowadays, this concern is truly unfounded. Modern microbiome tests are designed so cleverly that the entire process takes place discreetly, hygienically, and surprisingly simply in your own home.

You won't be left on your own. Every good test kit guides you through the process step by step, and everything you need is included. Usually, you begin by activating your kit online with an individual code. This is important so that your sample can later be assigned anonymously and your privacy protected. This way, you can be sure that only you will be able to see your results.

Collecting the sample is easier than you think

Now let's get to the key part: collecting the sample itself. Most kits include a simple paper collection aid that you stretch over the toilet seat. This prevents the sample from coming into contact with the toilet water—a clean solution.

Then comes the crucial moment, which takes only a few seconds. Using a small swab or spoon, you collect a tiny amount of your stool. Often, a sample the size of a grain of rice is enough. That may sound like very little, but for modern laboratory methods such as 16S rRNA gene sequencing, it is more than enough to extract and decode the complete DNA of your gut bacteria.

This sample then goes directly into a special tube that is already filled with a stabilizing liquid. This liquid is essential because it preserves the bacteria's DNA and ensures that the sample remains intact on its way to the laboratory and that the result is not distorted.

Our tip: Set aside time to collect your sample on a day when you feel relaxed. Stress has no place here. Also, try to send the sample between Monday and Wednesday. This will prevent it from sitting in the mail center over the weekend and its quality suffering.

The entire process, from your sample to the completed report, can be roughly divided into three phases.

This illustration shows how seamless the process is designed to be. The goal is to provide you with a well-founded analysis without requiring you to attend a doctor's appointment.

Off to the post office and the specialist laboratory

Once the sample is securely sealed in the tube, place everything in the enclosed, usually prepaid return envelope. Now all you have to do is drop it into the nearest mailbox—and the hardest part is already done.

From here on, the experts in the laboratory take over. Your sample is professionally prepared, the bacterial DNA is isolated, and then sequenced. Within a few weeks, this complex raw data is analyzed and translated into a clear, easy-to-understand results report that you can easily access digitally.

This is the first, but crucial, step toward turning a vague gut feeling into concrete data and a clear plan for your gut health. If you would like to learn more about the exact process and how to prepare properly, you can find more details in our guide to the at-home stool test.

How to correctly interpret and understand your report

It's finally here: your personal results report. But instead of immediate clarity, you will probably first see a lot of charts, Latin bacterial names, and metrics that raise more questions than they answer. Don't worry, that's completely normal. Let's go through it together and translate this scientific data into practical information for your everyday life.

A good report is far more than just a list of bacteria. Think of it as a kind of map of your inner ecosystem. It shows you where your strengths lie and where there may be a few areas that need attention. You don't have to be a biologist to read this map—you just need to know what to look out for.

The most important metrics in your report

Your report will very likely highlight several key values. These are the cornerstones of your analysis and give you a quick initial overview of the state of your gut microbiome.

• Bacterial diversity: This may be the most important number of all. High diversity means that countless different bacterial species live in your gut. Think of it as a healthy, thriving rainforest: The more different plants and animals there are, the more stable and resilient the entire system is. Low diversity, on the other hand, makes your gut more susceptible to disruptions.

• Dysbiosis Index: This value summarizes the overall balance of the microorganisms in your gut in a single number. A high value indicates an imbalance (known as dysbiosis), in which potentially harmful bacteria could gain the upper hand.

• Firmicutes-to-Bacteroidetes ratio: These two major bacterial phyla are the dominant groups in our gut. Research suggests that their ratio may play a role in energy metabolism and, consequently, body weight. An altered ratio could indicate that your body tends to extract more calories from food and store them as fat.

Your results are not a definitive diagnosis, but a valuable guide. They show you trends and potential opportunities that you can use to specifically improve your well-being.

From numbers to concrete action

The real treasures in your results are often found in the details. It’s not just about acknowledging the key figures, but about understanding the specific bacterial strains and their functions.

Here’s a practical example: Your test might reveal a deficiency of Akkermansia muciniphila. This bacterium is a true specialist when it comes to maintaining and strengthening the intestinal lining. Its absence could explain why you may react more sensitively to certain foods or why your immune defenses are somewhat weakened.

Or perhaps your results show low levels of Faecalibacterium prausnitzii. This bacterium is one of the most important producers of butyrate. This short-chain fatty acid serves as the main fuel for your intestinal cells and has a strong anti-inflammatory effect. A low level could therefore certainly be linked to low-grade inflammatory processes in the body.

By the way, microbiome research in Germany is developing rapidly and is constantly producing new findings that make such analyses increasingly precise. For example, Dr. Lukas Mager from Tübingen University Hospital received an ERC Starting Grant of around 2 million euros to investigate how specific bacterial species influence the risk of colorectal cancer and inflammatory bowel disease. Research like this is making the personalized recommendations from a microbiome test increasingly well-founded. Learn more about the exciting microbiome research from Tübingen.

Ultimately, it’s about recognizing the connections. You no longer just stare at numbers—you understand why you might feel low on energy, why your digestion may be acting up, or why your immune system needs support. And with this knowledge, you know exactly where to start.

What now? How to put your results into practice

A test result is a fantastic thing, but in the end it is just a piece of paper—or a PDF. It only becomes truly valuable when you use the insights to make real changes. Think of the result as your personal map of your inner ecosystem. Now it is about finding the right paths and taking action.

The biggest lever you have immediate control over is probably your diet. This is where we encounter two terms that are often lumped together but have very different roles: prebiotics and probiotics.

Feed your good roommates

Think of prebiotics simply as your beneficial gut bacteria's favorite food. They are essentially special types of fiber that you cannot digest but that provide the good microbes in your gut with a veritable feast. So if your test results show that certain bacterial strains are a little weak, you can specifically nourish them with their favorite food.

You can find some of the best sources of prebiotics right at the supermarket:

• Vegetables: Leeks, asparagus, onions, garlic, and artichokes are especially good choices. Chicory is also a real champion.
• Legumes: Lentils, beans, and chickpeas are not only sources of protein but also packed with valuable fiber.
• Whole grains: Oatmeal, barley, and rye are an excellent foundation for supporting your gut flora every day.
• Fruit: Slightly green bananas are a little insider tip. They contain resistant starch, which acts similarly to a prebiotic.

Probiotics, on the other hand, are something different. They are the good bacteria themselves—living microorganisms that you introduce into your body to enrich your gut community with new, beneficial members. You find them primarily in fermented foods such as plain yogurt, kefir, fresh sauerkraut, or Korean kimchi. Ideally, the selection of probiotic cultures should match your individual test results so that you strengthen exactly the strains that need it in your gut.

The key point is this: You don't have to turn your entire life upside down overnight. Just start gradually incorporating more fiber-rich foods into your daily routine. Pay attention to how you feel. Patience really is your most important companion here.

More than just eating: Your lifestyle matters

Your gut is not an isolated island. It reacts sensitively to everything that happens in your life. Your entire lifestyle plays a huge role in maintaining the balance of your inner world.

• Managing stress: We can only confirm it: chronic stress is toxic to the gut. It can make the intestinal barrier more permeable and noticeably reduce the diversity of your beneficial bacteria. Even simple things like meditation, a little yoga, or mindful breathing exercises can work wonders here.
• Good sleep: Getting enough sleep is non-negotiable. While you sleep, essential repair and regeneration processes take place throughout the body – and especially in the gut. Give it this time.
• Exercise, but do it right: Regular, moderate exercise stimulates intestinal activity and can have a positive effect on bacterial diversity. But beware: Overtraining can have the opposite effect and put stress on the body. Find a healthy level that feels good for you.

Your test result is the starting point. Real change comes from combining targeted nutrition with a mindful lifestyle.

Frequently asked questions about the microbiome test

It’s great that you’re exploring the topic so thoroughly. When venturing into new territory, questions naturally arise. And that’s a good thing. To help you feel confident in your decision, we’ve collected the most frequently asked questions we encounter here—with short, straightforward answers.

How often should I have my microbiome tested?

Your first test is like a snapshot—a solid foundation for understanding what is actually going on in your gut. It gives you a clear starting point.

A further test makes sense once you have genuinely changed something. However, give your body and microbiome enough time to respond to the new stimuli. We usually recommend scheduling a follow-up test after around six to twelve months. This way, you can see in black and white whether your dietary changes or new fitness program have paid off. It is the best way to make your progress truly measurable.

Do medications affect the test result?

Yes, absolutely. Antibiotics in particular act like a kind of clear-cutting operation for your microbiome. Unfortunately, they do not distinguish between beneficial and harmful bacteria and can drastically reduce the diversity in your gut.

To get a truly representative picture of your “normal state,” you should definitely be patient. Our advice: Wait at least four to six weeks after your last course of antibiotics before collecting the sample.

Other medications can also have an impact. If you’re not sure, it’s best to quickly ask your doctor or pharmacist. A brief conversation can remove a lot of uncertainty here.

Who can benefit most from a microbiome test?

Basically, the test is interesting for anyone who wants to take their health into their own hands. However, there are a few cases in which an analysis can be particularly revealing:

• People with chronic digestive problems: If bloating, cramps, constipation, or diarrhea are part of your everyday life, a test can often reveal the underlying imbalances (dysbiosis).
• People with unexplained food intolerances: Often, these are not true allergies, but reactions related to a weakened intestinal barrier or a lack of bacteria that help with digestion.
• People with weakened immune systems: A huge part of our immune defenses is located in the gut. A test can provide important pieces of the puzzle as to why you may be more susceptible to infections.

Demand for tests like these has noticeably increased in Germany in recent years. We’re not surprised. A study by the BARMER health insurance fund showed back in 2017 that around 11 million Germans regularly struggle with digestive issues. Stress and an unbalanced diet are often the main suspects. You can find more background on this topic, for example, at gesundheitsvergleich-deutschland.de.

Ultimately, it’s about no longer feeling in the dark, but making informed decisions for your body.
