Gut microbiome analysis: Discover how your gut health works

A gut microbiome analysis is a modern health test that helps you investigate the composition of the trillions of microorganisms in your gut. All that is required is a simple stool sample, which you can conveniently collect at home. This sample is used to decode your personal microbiome and identify a possible imbalance (dysbiosis) that may be behind a wide range of complaints.

Understanding your gut as an ecosystem

Don't think of your gut simply as an organ, but rather as a vibrant, living ecosystem. In this complex system—your gut microbiome—trillions of microorganisms (bacteria, viruses and fungi) live and work for you every single day. They are absolutely essential to your health and influence far more than just your digestion.

These tiny helpers are true all-rounders. They support your immune system, about 70% of which is located in the gut, produce important vitamins and even influence your mood and mental wellbeing through the gut-brain axis. As long as this ecosystem remains balanced, you feel fit, energised and completely well.

When the balance is disrupted

But what actually happens when this sensitive system gets out of balance? Such a disruption, also known as dysbiosis in medical terminology, can manifest through a wide range of non-specific symptoms that you would not immediately associate with the gut.

These include, for example:

• Constant bloating and irregular digestion
• Persistent tiredness and a lack of energy in everyday life
• Skin problems such as acne, eczema or a dull complexion
• Unexplained weight fluctuations or difficulty losing weight

When experiencing such complaints, many people turn to generic diets or well-intentioned advice, but these often do not address the individual cause. So you no longer have to feel in the dark, a targeted gut microbiome analysis can finally provide clarity.

You are not alone in experiencing digestive problems. A 2024 study shows that three out of five people in Germany suffer from intestinal complaints. This highlights how important it is to take your own gut health seriously and take proactive action. Find out more about the latest findings in the Mintel Gut Health Market Report.

Personalised instead of one-size-fits-all

Rather than treating symptoms alone, an analysis gets to the bottom of the actual cause. A self-test such as the mybody-x gut test provides you with a detailed snapshot of your inner ecosystem. It shows you precisely which bacterial strains predominate in your gut, where there may be a deficiency, and how diverse your tiny gut inhabitants are.

With this knowledge, you'll finally learn to correctly interpret your body's signals. You'll discover why a personalized approach tailored precisely to your microbiome's needs is the key to lasting well-being. Instead of following general recommendations, you'll receive a clear roadmap adapted to your unique body. If you'd like to delve deeper into the fascinating world of gut bacteria, you can read more in our article about what the microbiome actually is.

How easy it is to analyze your gut microbiome at home

The very thought of providing a stool sample initially puts many people off. But the days when this was a complicated and unpleasant procedure are long gone. Modern test kits, like those from mybody-x, are designed so intelligently that the entire process takes place simply, hygienically, and discreetly in your own bathroom.

We'll guide you through how simple a gut microbiome analysis can be today. You don't need to make a doctor's appointment or wait at a medical practice. Instead, you can conveniently order your test kit online and have everything you need delivered directly to your home.

From ordering to the laboratory

The process is divided into a few clear steps so that you always feel confident. You'll be surprised by how smoothly and thoughtfully everything works.

Here's how it works:

1. Receive your test kit: Your package contains everything you need – a sample tube, a hygienic collection aid, and precise, easy-to-understand instructions.
2. Collect the sample: Thanks to the clever collection aid, the process is clean and takes just a few minutes. The only important thing is to follow the instructions so that your result is genuinely meaningful.

If you are unsure about collecting the sample, we have a detailed guide for you that shows you exactly what to do at every step: How to collect a stool sample correctly.

Analysis using state-of-the-art technology

As soon as your sample arrives at the laboratory, the actual scientific work begins. This is where cutting-edge technology comes into play to decode the unique ecosystem in your gut.

Using a process called 16S rRNA gene sequencing, the DNA of your gut bacteria is analyzed. Imagine it as taking a genetic fingerprint from each individual bacterial strain. This allows the laboratory to determine exactly which bacterial species live in your gut and in what quantities.

This process makes it possible to create a detailed profile of your microbiome. It shows not only the diversity of the microorganisms living in your gut, but also the ratio of important bacterial groups to one another.

At mybody-x, your sample is analyzed exclusively in an ISO 15189-certified specialist laboratory in Germany. This certification is an internationally recognized quality standard for medical laboratories and guarantees the highest precision and reliability of the results.

The highest standards for your safety

Your health and your data are your most valuable assets. That is why it is absolutely essential that a provider of gut microbiome analyses meets the highest safety and quality standards. With mybody-x, you can rest assured that your sample and personal information are in the best hands.

These standards give you the assurance that you can trust the entire process—from the simple collection of your sample at home to the clear evaluation of your results. You receive a sound foundation for taking your health into your own hands, without having to worry about quality or the protection of your data.

Deciphering and truly understanding your report

You are holding your report in your hands—a detailed document full of scientific terms, numbers, and charts. At first glance, it can seem quite intimidating. But don’t worry: This report is not a complicated laboratory file, but your very own map to greater well-being. Together, we’ll now translate the most important results of your gut microbiome analysis into clear, easy-to-understand insights for your everyday life.

This section gives you the tools you need to decipher your report and finally understand where you can start. You will see how the data suddenly explain your symptoms—whether bloating, fatigue, or skin problems—and show you the way to targeted improvements.

The following graphic shows you in a simple way the journey your sample takes from your home to the completed laboratory analysis.

Every step, from the test kit and sample collection to laboratory analysis, is designed to provide you with precise and reliable data about your microbiome.

The diversity of your microbiome

One of the most important values in your report is bacterial diversity, often also called diversity. Simply imagine your gut as a flourishing garden. A healthy garden does not stand out because of a single plant species, but because of a colorful mix of flowers, herbs, and shrubs. They all support one another and make the entire ecosystem resilient.

The same applies in your gut. A high diversity of different bacterial species makes your microbiome resilient to disruptions. It can better defend itself against harmful pathogens, utilize nutrients optimally, and perform important functions for your immune system. Low diversity, on the other hand, makes the system vulnerable and is often associated with chronic inflammation, digestive problems, and even difficulty losing weight.

The Firmicutes–Bacteroidetes ratio

Another key measurement is the ratio of the two major bacterial phyla, Firmicutes and Bacteroidetes. These two groups dominate our gut and have a huge influence on our metabolism and body weight.

• Bacteroidetes are considered the “slender” bacteria. They are experts at breaking down complex carbohydrates (i.e., fiber), thereby making fewer calories available to the body.
• Firmicutes, on the other hand, are particularly efficient “energy harvesters.” They extract more energy from the same food and tend to store excess energy as fat.

An imbalance in favor of Firmicutes can mean that your body extracts more calories than average even from healthy food. This can make it damn difficult to maintain or lose weight, even if you eat mindfully.

Your report shows your personal ratio of these bacterial groups. This information is extremely valuable because it explains why generic diets may not work for you and how you can specifically adjust your diet to bring your microbiome back into balance.

Important bacteria and their functions

In addition to the major groups, a good gut flora analysis also examines specific bacterial species and their functions. A particularly important example is butyrate-producing bacteria. Butyrate is a short-chain fatty acid that serves as the main energy source for your intestinal cells.

It strengthens the intestinal barrier, has an anti-inflammatory effect, and supports a healthy intestinal environment. A deficiency of butyrate producers, such as Faecalibacterium prausnitzii, is often found in people with irritable bowel syndrome, bloating, or chronic inflammatory bowel diseases. If your report shows such a deficiency, you know exactly what you need to work on: deliberately eat foods that promote the growth of these beneficial helpers.

The following table gives you a quick overview of the most important measurements and what they mean for you.

Important measurements from your gut flora analysis and what they mean This table explains the key parameters in a microbiome report and what they mean for your health.

Measurement	What it means	Potential effects of deviations
Bacterial diversity	The number of different bacterial species in your gut. A high value is a sign of a healthy, stable microbiome.	Low diversity is associated with digestive problems, inflammation, and increased susceptibility to infections.
Firmicutes/Bacteroidetes ratio	The balance between the two most dominant bacterial phyla, which strongly influence energy metabolism.	A higher proportion of Firmicutes may indicate more efficient calorie absorption and make it harder to maintain or lose weight.
Butyrate-producing bacteria	Beneficial bacteria that produce butyrate—a fatty acid that strengthens the intestinal wall and reduces inflammation.	A deficiency can lead to a weakened intestinal barrier (“leaky gut”), bloating, and an increased risk of chronic intestinal diseases.
Akkermansia muciniphila	An important bacterium that supports the intestinal lining and is associated with a healthy metabolism and body weight.	Low levels are often observed in people with obesity, type 2 diabetes, and inflammatory conditions.
Potentially harmful bacteria	Bacteria that are normal in small amounts but can cause problems when they overgrow (e.g., certain clostridia).	An excess can cause gas, bloating, diarrhea, or inflammation and disrupt the balance of the gut flora.

With this information, you can assess your results much better and recognize the connections to your well-being.

If you would like to learn more about how the results of an analysis are interpreted and what significance they have, you will find a detailed explanation of microbiome analysis in our further reading article.

However, the results of a mybody-x gut test provide you with more than just this raw data. They translate it directly into easy-to-understand graphics and, more importantly, personalized recommendations for action. This lets you find out exactly which foods and lifestyle adjustments can help you increase diversity, optimize the Firmicutes-to-Bacteroidetes ratio, or boost butyrate production.

From knowledge to action: Your personal roadmap

A gut flora analysis is only as good as the plan that ultimately comes from it. Imagine your results as a map of your inner ecosystem—now it is time to set out on the journey. This section gets practical: We show you how to translate the insights from your microbiome profile into concrete everyday strategies and create your personal roadmap to a healthier gut.

You will quickly notice that this is not about blanket advice. Instead of blindly following just any diet, you begin to support your body in a targeted way and build up exactly what it lacks.

Feed your beneficial bacteria with prebiotics

The key to a healthy microbiome often lies in specifically “feeding” your beneficial bacterial strains. This is exactly where prebiotics come into play. These are special, indigestible fibers that serve as a favorite food for your beneficial gut inhabitants and strongly stimulate their growth.

However, not every prebiotic food is equally beneficial for everyone. Your analysis results reveal which of your bacteria particularly need an extra portion of food. For example, if you lack butyrate-producing bacteria, foods rich in resistant starch are your trump card.

Here are some examples of targeted prebiotic nutrition:

• Resistant starch: It forms when you cook starchy foods such as potatoes, rice, or pasta and then let them cool again. It is the absolute favorite food of many butyrate producers.
• Inulin: Found primarily in chicory, Jerusalem artichokes, artichokes, and onions. It specifically promotes the growth of bifidobacteria.
• Pectins: Found abundantly in apples, carrots, and berries. They support a diverse gut flora and help strengthen the intestinal barrier.

Boost your diversity with probiotics

While prebiotics feed the beneficial bacteria already present in your gut, probiotic foods deliver new, live microorganisms directly to your intestines. They are like fresh reinforcements for your team and can help increase bacterial diversity and restore balance to a microbiome that has fallen out of sync.

Here too, targeted use is crucial. Kefir, yogurt, raw sauerkraut, kimchi, and kombucha contain very different bacterial strains. Your results can provide valuable insights into which types of probiotic foods might be particularly beneficial for you. One specific approach is to provide targeted support for the gut flora, for example by using live microorganisms, as studies in humans have done to improve gut health. Research in other areas is also interesting in this context, such as probiotics for dogs, where very similar principles are applied.

Your plan is as individual as you are

General recommendations often only go so far. The true value of a gut flora analysis lies in personalization. Let’s look at two fictional examples to make this more tangible:

Case study A: Lena, 34, suffers from constant bloating and fatigue.

• Her findings: A significant lack of butyrate-producing bacteria and low overall diversity.
• Her plan: She deliberately incorporates cooled potatoes and whole-grain rice into her diet to boost butyrate production. She also adds fermented foods such as kefir and a small glass of sauerkraut juice every day to increase diversity.

Case study B: Tom, 42, wants to lose weight, but his weight has plateaued despite exercising.

• His findings: An unfavorable Firmicutes-to-Bacteroidetes ratio, suggesting overly efficient calorie absorption.
• His plan: Tom focuses on a high-fiber diet rich in vegetables, legumes, and flaxseed to feed the “lean” Bacteroidetes. He reduces simple sugars and processed foods, which primarily promote Firmicutes.

These examples show that your mybody-x report doesn’t just tell you what is wrong, but also how you can make targeted changes.

More Than Just Nutrition: Your Holistic Approach

A healthy gut flora needs more than just the right food. Your lifestyle has just as much influence on the well-being of your gut inhabitants. That’s why the following three pillars are an integral part of your personal roadmap:

1. Stress Management: Chronic stress can negatively alter the composition of your gut flora and weaken the intestinal barrier. Techniques such as meditation, yoga, breathing exercises, or regular walks in nature can help lower your stress levels and protect your microbiome.

2. Sleep Quality: While you sleep, your entire body regenerates—including your gut. Lack of sleep disrupts not only your hormone balance but also the balance of your gut bacteria. Try to sleep 7–8 hours per night and establish a regular sleep routine.

3. Regular Exercise: Moderate exercise promotes intestinal activity (motility) and the diversity of your gut flora. You don’t have to run a marathon. Regular walks, cycling, or swimming are enough to achieve a noticeable positive effect.

The personalized recommendations in your mybody-x test take all these aspects into account. They provide you with a comprehensive, actionable roadmap that enables you to actively improve your gut health and overall well-being—step by step and based on your own data.

The Future of Gut Health Is Personalized

Research into our microbiome never sleeps. What impresses us today as a detailed gut flora analysis may already be standard tomorrow—the field is advancing that rapidly. So let’s take a look at where things are headed and why the future of gut health will become much more personal.

The focus is already shifting away from simply counting bacterial strains toward understanding complex networks. It’s no longer just about which bacteria are present, but rather what they actually do and how they work together as a team. The goal is increasingly precise, personalized healthcare.

New Building Blocks for Your Microbiome

You probably already know about probiotics (the live bacterial cultures) and prebiotics (the food for these bacteria). But science is already focusing on the next generation of helpers that can improve your gut health even more precisely.

These include two particularly exciting concepts:

• Synbiotics: This is the clever combination of probiotics and prebiotics in a single product. Think of it this way: You are not only introducing new beneficial bacteria, but also providing them with their favorite food as a welcome gift. This allows them to establish themselves much more effectively in your gut and begin their beneficial work.
• Postbiotics: The focus is no longer on the bacteria themselves, but on their valuable metabolic products. These include short-chain fatty acids such as the important butyrate, as well as enzymes and other bioactive substances. They act directly on your intestinal cells, can inhibit inflammation, or strengthen the all-important intestinal barrier.

These new approaches make it possible to respond much more specifically to your analysis results and address gaps in care more directly.

Expert forecasts already show where things are heading. Personalized microbiome analyses are expected to fundamentally transform gut health in Germany in the near future—moving away from simply counting bacteria toward a deep understanding of bacterial networks. In this context, synbiotics and postbiotics are becoming increasingly important because they can act more precisely. Learn more about how these new approaches are changing gut health.

Artificial intelligence as your personal health coach

We are taking personalization to the next level with the help of artificial intelligence (AI). Providers such as mybody-x are already pioneers in this field, combining sound science with personal consultation. In the future, AI will play an even greater role in interpreting the vast amounts of data from your gut flora analysis.

Imagine intelligent software that not only analyzes your microbiome but also links this data in real time with other information about you. This could include, for example, blood test results, your sleep patterns, or your current stress level.

Based on this comprehensive data, an app could provide you with dynamic, up-to-date recommendations. Perhaps it would suggest a different lunch today than tomorrow because you slept worse, or recommend a specific relaxation exercise because your stress level is currently rising. This is no longer a distant vision of the future. It is the next logical step toward giving you even more control over your well-being—based on your body's unique needs.

Everything else you want to know: Your questions about gut flora analysis

Finally, we want to answer the questions we keep receiving about a gut flora analysis. Perhaps you’ll recognize yourself in one or two of them—our goal is to resolve any remaining uncertainties and provide complete clarity.

How often should I have a gut flora analysis?

That’s a really good and important question! Your very first analysis is your personal baseline assessment, your “status quo.” It shows you where you currently stand and where there may be one or two areas of concern in your microbiome.

If you make targeted changes to your diet or lifestyle based on your results, a follow-up analysis after approximately three to six months is ideal. Your microbiome needs this time to respond to the new changes. With the second test, you’ll see in black and white whether your measures are bearing fruit and whether the composition of your gut bacteria has developed positively.

For chronic complaints or long-term preventive healthcare, an annual check-up can also be useful to keep track of everything. The mybody-x gut test and the recommendations associated with it can provide you with personalized guidance tailored precisely to your situation and goals.

Does a test like this replace a visit to the doctor?

A clear no. A gut flora analysis is an incredibly valuable tool for preventive healthcare and improving your well-being. However, it can never replace a medical diagnosis or treatment.

It’s best to think of the test as your personal everyday health detective. It’s perfect for getting to the bottom of the causes behind vague complaints such as constant bloating, unexplained fatigue, skin problems, or stubborn weight issues. It helps you take a proactive approach to your health and better understand your body.

Important: If you have acute, severe, or alarming symptoms—such as blood in your stool, intense pain, sudden weight loss, or persistent fever—seeing a doctor is always the first and most important step. The test is a useful supplement, not a substitute.

Do medications affect the results?

Yes, and to a very significant extent. Certain medications can drastically alter the composition of your gut flora. That’s why the timing of sample collection is crucial for obtaining meaningful results.

Antibiotics in particular have a massive impact. They do not distinguish between “good” and “bad” bacteria and can seriously disrupt your microbiome. We therefore strongly recommend waiting at least four to six weeks after antibiotic treatment before taking the test. This is the only way to obtain a representative picture of your “normal” gut condition.

Other medications can also affect the results. These include, for example:

• Stomach acid blockers (PPIs): Can alter the environment in the upper digestive tract.
• Metformin: Used to treat type 2 diabetes and known to affect the gut flora.
• Certain laxatives: When taken regularly, they can disrupt the balance.

When placing your order, be sure to state in the questionnaire which medications or dietary supplements you take regularly. This information is crucial for our experts to interpret your results correctly and provide you with the right recommendations.
