Happy Gut, Happy Mind
How your gut bacteria influence your mood and well-being
Do you sometimes feel butterflies in your stomach or a queasy feeling when you’re stressed? Your gut and brain are closely connected – and this very connection influences your mood and well-being. Your gut talks to you – and it has more influence on your mood than you might think. That’s because the gut and brain are closely linked via the gut-brain axis. Trillions of gut bacteria influence not only your digestion, but also your mood, your stress levels, and your mental resilience.
When this balance is disrupted – for example by stress, poor nutrition, or environmental stressors – it is often reflected in your well-being too. But you can actively counteract this: with a gut-friendly diet, targeted relaxation, and high-quality dietary supplements, you can build up your gut flora and improve your mood. In this article, you’ll learn how your gut and your psyche are connected and how you can strengthen your inner balance.
How the gut-brain axis influences your mood
Our gut is far more than just a digestive organ – it is a true team player that constantly communicates with our brain. This connection is called the gut-brain axis. The nervous system in the gut, also known as the enteric nervous system, contains around 100 million nerve cells and works closely with the brain. The most important mediator of this connection is the vagus nerve, which acts as a direct data highway between the abdomen and the head. It transmits signals in both directions and has a major influence on how we feel.
But nerves are not the only players here. Hormones and messenger substances such as serotonin, our “happiness hormone,” are also produced in the gut – about 90% of them. If the gut flora becomes imbalanced, this signal transmission can be disrupted – with consequences for our mood.
Medications such as antibiotics and highly processed foods with additives and preservatives can severely disrupt this balance by destroying not only harmful but also beneficial gut bacteria. Chronic stress has a similar effect: it increases the formation of free radicals, which attack the sensitive gut flora. The bacteria responsible for producing mood-enhancing neurotransmitters such as serotonin and dopamine are particularly affected. The result? Bad moods, exhaustion, or even depressive moods.
This shows: when your gut is doing well, your mind benefits too. But stress, an unhealthy diet, and medications can disrupt this delicate balance. So it’s high time to take good care of your gut!

Your gut whispers, your brain answers!
Gut bacteria and the psyche:
Why your gut feeling is more than just intuition
Sometimes the solution to a good mood is much closer than we think – more precisely, in our belly. Around 100 trillion microorganisms live there, together forming our microbiome. These tiny helpers influence not only our digestion, but also our mood, our stress levels, and even our behavior.
Especially exciting: certain gut bacteria play a key role in the production of serotonin – the hormone that makes us happy. These include:
- Lactobacillus plantarum – supports the production of serotonin and has a calming effect on the nervous system.
- Bifidobacterium infantis – strengthens the gut flora and may help alleviate depressive moods.
- The combination of Lactobacillus helveticus and Bifidobacterium longum has been shown in studies to reduce stress and anxiety.
But this delicate balance can easily be disrupted. Chronic stress, a one-sided diet, or antibiotics can displace valuable gut bacteria. Often, the very bacteria responsible for producing our “happiness hormones” are particularly affected. The result? Mood swings, irritability, and in the worst case even depressive moods.
And the numbers speak for themselves!
- People with chronic inflammatory bowel diseases such as Crohn’s disease or ulcerative colitis have up to a fourfold increased risk of developing depression or anxiety disorders.
- With irritable bowel syndrome, up to 90% of those affected also struggle with psychological complaints such as anxiety and depression.
- ADHD also shows that a disrupted microbiome could influence the development and severity of symptoms.
It becomes clear: when the gut is unwell, the mind suffers too. This makes it all the more important to protect and specifically strengthen our invisible companions – for greater inner balance and mental resilience.
Gut-friendly nutrition:
Lift your mood with the right foods
What you eat influences not only your digestion, but also your mood. With the right foods, you can actively strengthen your gut flora – and with it, your emotional well-being. Because a healthy gut is the foundation for mental resilience.

Fun fact:
After a targeted gut cleanse, you may weigh up to 2 kilograms more – but not because you have gained weight, rather because your gut is finally populated again with a wide variety of healthy bacteria.
A living microbiome simply adds quite a bit of weight to the scale!
Prebiotics and probiotics – the perfect team from nature
- Prebiotics are indigestible fibers that nourish your good gut bacteria. Natural sources include psyllium husks, chicory, artichokes, onions, and flaxseed. Bitter substances from herbs such as dandelion, artichoke, and gentian also stimulate digestion and promote healthy gut flora.
- Probiotics provide live microorganisms that directly support your gut flora. You can find them in fermented foods such as sauerkraut, kimchi, yogurt, kefir, kombucha, or MyREGULATE.

Healthy fats – energy for the gut and brain
Healthy fats are essential for gut and brain health. Omega-3 fatty acids, found in flaxseed oil, chia seeds, walnuts, and fatty fish, are especially valuable. They have anti-inflammatory effects, protect the gut barrier, and support brain function.
👉 Attention vegetarians and vegans: Plant-based omega-3 sources usually provide only alpha-linolenic acid (ALA), which is converted into the valuable fatty acids EPA and DHA only to a limited extent. Our vegan AlgaeDHA with directly usable omega-3 fatty acids offers a sensible supplement here.
Sugar, alcohol, and fast food – the enemies of your gut flora
As valuable as healthy foods are for your gut, other foods can be just as harmful:
- Sugar feeds harmful bacteria and yeasts in the gut. This promotes inflammation and weakens the gut barrier.
- Alcohol acts like a toxin for the microbiome. Even small amounts can disrupt the balance of the gut flora and irritate the mucous membranes.
- Fast food and highly processed foods provide hardly any nutrients, but plenty of additives that encourage the growth of harmful germs.
- Stress eating often leads us to reach for unhealthy snacks. Under stress, digestive processes slow down, and the intestinal mucosa suffers additionally.
The result: bad moods, lack of energy, and an increased risk of chronic inflammation. To relieve the gut, it is worth consciously reducing sugar, alcohol, and convenience foods.
Vitamin D and B12 – nutrients for your mental resilience
- Vitamin D not only strengthens the immune system, but also supports serotonin production. Especially in the winter months, a deficiency can affect your mood. Foods rich in vitamin D include eggs, fatty fish, and mushrooms.
- Vitamin B12 is essential for the nervous system and the formation of neurotransmitters. Since vitamin B12 is found almost exclusively in animal products, vegetarians and vegans have an increased risk of deficiency. Targeted supplementation with our SulfoCLEAN can be useful here.
👉 And if you want to support your gut flora even more specifically, there are natural helpers that bring your gut feeling back into balance – you’ll learn more about this in the next section.

Conclusion:
With a varied diet full of natural prebiotics and probiotics, healthy fatty acids, bitter substances, and sufficient vitamin D and B12, you lay the foundation for a happy gut – and therefore for a stable, positive mindset.
Targeted nutrients for strong gut flora and greater well-being
Even if you already support your gut with a balanced diet, it may need an extra dose of care during stressful phases or periods of particular strain. This is where targeted nutrient helpers come into play, strengthening your inner balance. These include:
- Growth phases in children and adolescents
- Pregnancy and breastfeeding
- Stressful phases of life and high professional pressure
- Competitive sports and physically demanding activities
- Smoking and regular alcohol consumption
- Advancing age
Yet even with a balanced diet, it has become more difficult today to absorb all essential nutrients. Soils are depleted by intensive agriculture, fruit and vegetables contain fewer vitamins and minerals, and highly processed foods with high sugar and fat content dominate our diet. Studies show that today we consume only about 10% of the amount of fiber that was common among rural populations 50 years ago.
Another problem concerns vitamin D: due to our modern lifestyle, we spend a lot of time indoors. Especially in winter, sunlight is not sufficient to produce enough vitamin D. It is also difficult to meet requirements through diet alone. In such cases, targeted dietary supplements can be useful to support the body in the best possible way.

Staying in balance – why stress reduction and exercise are good for your gut
Stress is part of life, but chronic stress can have serious consequences for your health – especially for your gut. When we are under constant pressure, the body releases more of the stress hormones cortisol and adrenaline. While short-term stress activates the body, a permanently elevated cortisol level harms the intestinal mucosa, weakens the microbiome, and promotes inflammation.
Studies show: people with chronic stress or anxiety disorders often have elevated cortisol levels, which increases the risk of gut problems and psychological complaints.
A persistently high cortisol level leads to:
- a weakened intestinal mucosa
- an imbalance in the gut flora
- an increased tendency toward inflammation in the body
- and increased anxiety and mood swings
Why stress affects the stomach
Do you know that queasy feeling in your stomach when you’re stressed? That’s no coincidence! Stress activates the nervous system and influences intestinal activity. Digestive processes are slowed down, blood flow to the gut decreases, and the production of digestive enzymes is inhibited. At the same time, more free radicals are produced, which attack the sensitive intestinal mucosa and can damage beneficial gut bacteria.
A gut under constant stress quickly becomes imbalanced – with consequences for your digestion, your immune system, and your mood. That’s why it’s important to reduce stress and specifically support the body with antioxidants.

Active H®:
Cell Protection During Stress and for a Healthy Gut
Stress leaves its mark – especially in the gut. Active H® provides highly effective antioxidants that neutralize free radicals and protect your cells. This keeps your microbiome stable and your body resilient, even in stressful times.
🛡️ Your benefit:
Cell protection, fewer effects of stress, and a strengthened immune system..
👉 Protect your cells – with Active H® against stress and inner restlessness!

Exercise – Activity for an Active Gut
Regular exercise not only keeps you fit, but also gets your gut moving. Moderate endurance activities such as cycling, swimming, or walking promote intestinal movement (peristalsis) and support natural detoxification.
The 8 essential amino acids are particularly important for active muscles and rapid regeneration. MyAMINO® provides them in pure form and optimally supports the body – perfect for anyone who wants to stay active regularly.
Targeted pelvic floor and abdominal muscle exercises also stimulate digestion. Especially for people with a sensitive gastrointestinal tract, gentle movement is ideal for gently activating the gut.
Tip: Even small changes in everyday life – such as conscious breathing exercises, yoga, or short walks – help lower cortisol levels, reduce stress, and strengthen your gut health.

Gut health is self-care for body and soul!
Ten everyday tips for a happy gut and a strong mindset
Sometimes it’s the small changes that make the biggest difference. With these simple but effective tips, you can specifically promote your gut health while also supporting your mental resilience.
- Start the day with a glass of warm water and lemon
This gently stimulates digestion and prepares the gut for the day. Optionally, you can also add a spoonful of psyllium husks or ColoSTABIL® to increase your fiber intake. - Incorporate fermented foods into your diet
Sauerkraut, kimchi, fermented BRAVO yogurt, kombucha, or MyREGULATE provide natural probiotics that strengthen your gut flora. - Eat mindfully and chew thoroughly
Eating slowly and chewing consciously relieve the digestive tract and promote nutrient absorption. - Treat yourself to daily breaks
Just 10 minutes of meditation, breathing exercises, or a short walk help lower cortisol levels and relax the gut-brain axis. - Rely on bitter substances
Herbs such as dandelion and artichoke, as well as our bitter herb aperitifs HerbiGOLD and CHI extracts, support digestion and stimulate the production of digestive juices. - Make exercise a fixed part of your day
Integrate gentle movement, such as yoga, cycling, or a walk after eating, to promote intestinal activity. - Pay attention to your sleep quality
Restful sleep supports the body’s regeneration and the breakdown of stress hormones. Regular sleep times and a relaxing evening routine help with this. Active H® day can support your body’s natural production of melatonin. - Consciously reduce sugar and alcohol
Both substances harm the gut flora. Try to avoid highly processed foods and switch to natural alternatives such as the ketogenic diet. - Target nutrient gaps specifically
If diet alone is not enough, high-quality dietary supplements such as MyREGULATE, ColoSTABIL®, or VitaDK plus but above all the eight essential amino acids in MyAMINO® can meaningfully support your health. - Listen to your gut feeling
Pay conscious attention to your body’s signals. Digestive problems, fatigue, or mood swings can be signs of an imbalance in the gut.
Tip: You don’t have to change everything at once. Even small steps make a big difference – and your gut will thank you!
