Stress doesn't only affect your mind.
When life feels overwhelming, the effects are often felt far beyond your thoughts. Modern research shows that your gut and brain are constantly communicating through the gut-brain axis.
That’s where OMNi-BiOTiC® SR-9 with B-vitamins comes in: A probiotic formulation based on years of research of the connection between stress and the gut microbiome.
Stress doesn't only affect your mind.
When life feels overwhelming, the effects reach far beyond your thoughts. Gut and brain talk to each other constantly via the gut-brain axis — which is why demanding phases are often felt in the body too.
That’s where probiotics come in: they support your gut microbiome even when life is demanding.

Stress can show up in many ways. For some, it starts with a busy mind that will not slow down. For others, it affects sleep, digestion, mood or the feeling of being able to cope with everyday life. Women in particular often experience stress alongside hormonal changes, mental load, busy routines or phases of life that demand more from the body than usual.
That is why stress should not only be viewed as something that happens in the mind. The gut and brain are closely connected through the gut-brain axis and are in constant communication with each other. This connection is one reason why demanding periods can also be felt physically — from the stomach to energy levels and overall wellbeing.
For more than 30 years, Institut AllergoSan with the leading probiotic brand number 1 in Europe “OMNi-BiOTiC®” has been researching the connection between stress, wellbeing and the gut microbiome.
Everyday signs of stress
- Constantly switched on: You struggle to relax, even when the day is over.
- Feeling mentally drained: Small tasks suddenly feel overwhelming.
- Your gut reacts during stressful periods: Stressful situations can often be accompanied by digestive discomfort.
- Less resilience than before: You feel like you have less energy for the things that matter.
Nodding along to even one? It might be time to look beyond the mind — and start with your gut.

Your gut and brain are in constant conversation
The gut–brain axis connects your digestive system and brain through nerve pathways, hormones, and messengers such as serotonin.
When your gut microbiome is in balance, it can support mood, energy and how you cope. Disruption — from stress, diet or illness — can tip that balance.
That's where probiotics come in: helping maintain a healthy gut environment — supporting calmer days, from the inside out.

Probiotics matter for your gut microbiome
Probiotics contain selected beneficial bacterial strains. They help restore and maintain a healthy gut environment, supporting smoother communication between the gut and brain.
The result? A calmer mind, a more resilient body, and better overall well-being — from the inside out.
When choosing a probiotic, it is worth looking at the specific bacterial strains it contains — and whether these strains have been scientifically studied. Especially in more complex areas such as stress and the gut-brain axis, the focus should not only be on individual strains, but also on how they work together as a carefully selected combination. This is why multi-strain formulations that have been researched as a whole can be particularly relevant for supporting a balanced gut microbiome.

When stress follows you into the night
A busy mind can make it difficult to truly switch off. Sleep, stress and wellbeing are closely connected — and all three can influence how resilient we feel in everyday life.
B vitamins play an important role in supporting the body during demanding times. Vitamins B6 and B12 contribute to normal psychological function and the normal functioning of the nervous system, while vitamins B2, B6 and B12 help reduce tiredness and fatigue.

Stress, sleep and your gut: frequently asked questions
Stress can show up in many ways — from a busy mind at night to changes in digestive comfort. To help you better understand what may be happening in your body, we’ve answered the most common questions about the gut-brain axis, the gut microbiome and everyday wellbeing.
What is the gut-brain axis?
The gut and brain are constantly communicating through a complex network of nerves, hormones and signalling molecules. Researchers refer to this connection as the gut-brain axis. It helps explain why emotional stress can sometimes be felt in the digestive system – and why gut health has become an important area of scientific research.
Can stress affect digestion?
Many people notice changes in their digestion during stressful periods. While everyone responds differently, research suggests that stress can influence gut function, digestive comfort and the balance of the gut microbiome.
Why is the gut sometimes called the “second brain”?
The gut contains its own extensive network of nerves, known as the enteric nervous system. Because of its close communication with the brain, it is sometimes referred to as the body’s “second brain”.
What is the gut microbiome?
The gut microbiome refers to the trillions of microorganisms that naturally live in the digestive tract. These microorganisms play a role in various bodily functions and are increasingly being studied for their connection to overall wellbeing.
Why do stress and sleep seem so closely connected?
Stress can make it more difficult to relax and switch off at the end of the day. Poor sleep may then affect how resilient we feel the next day, creating a cycle that many people recognise during demanding periods of life.
Can everyday habits influence the gut microbiome?
Factors such as diet, sleep, physical activity and stress management are all thought to play a role in supporting a healthy gut microbiome. Small, consistent lifestyle habits can often make a meaningful difference over time.
Why is the gut microbiome receiving so much scientific attention?
Over the last two decades, researchers have discovered that the gut microbiome is connected to many aspects of human health. As a result, it has become one of the fastest-growing areas of health research worldwide.
