The gut does much more than simply digest food. A healthy gut helps the body absorb nutrients, supports the immune system and contributes to your pet’s overall wellbeing. When the delicate balance of the gut is disrupted, problems such as diarrhoea, flatulence or acid reflux may occur.
A suitable diet and a supplement that supports normal gut function, such as Nutrolin® GUT & FLORA, can help promote gut health in dogs and cats.
Gut health plays an important role in your dog’s or cat’s overall wellbeing
Today, we know that the gut is much more than a digestive organ. It plays a significant role in the health and wellbeing of both humans and animals.
The digestive system breaks down food so that the body can absorb the nutrients it needs to stay healthy. Gut microbes, especially gut bacteria, play a particularly important role in this process. The more beneficial bacteria there are, the healthier the gut tends to be.
These bacteria form a complex ecosystem that constantly works to support your pet’s wellbeing. A balanced gut microbiota supports digestion, helps maintain normal intestinal function and contributes to the body’s natural defence mechanisms.
When this delicate ecosystem is disrupted, digestive problems such as diarrhoea, flatulence or changes in stool consistency may occur.
It is worth looking after your pet’s gut health even when everything seems to be working normally.

What can upset your dog’s or cat’s stomach?
Digestive problems are among the most common reasons pet owners seek advice and support.
Several everyday factors can put extra strain on the digestive system.
Changes in diet
When changing your dog’s or cat’s food, make the transition gradually whenever possible. Start by mixing a small amount of the new food with the familiar food.
A new food should ideally be introduced over a period of weeks. Its suitability cannot always be determined after just a few meals, as the digestive system needs time to adapt. In some cases, unpleasant symptoms may only appear after the food has been used for a longer period.
It is also important to avoid unnecessary changes in diet. For pets with sensitive stomachs in particular, it is often best to stick to familiar, well-tolerated ingredients.
Antibiotic treatments
Antibiotics help fight harmful bacteria, but they can also affect the beneficial bacteria in the gut. As a result, digestive function may change during and after a course of antibiotics.
Stress
Many pets react to stress through their digestive system. Changes in daily routines, being left alone, unfamiliar people or animals and other new situations can all affect gut function.
Travelling
Travelling can also cause digestive upset. New environments, unfamiliar routines, excitement and exposure to different bacteria may put additional strain on the gut.
While travelling, your pet may have a reduced appetite or looser stools. Changes in behaviour are also common.
Sports and activities
Dog and cat shows, hunting and other active hobbies place demands on both the body and mind. Increased physical exertion, particularly during competition or hunting seasons, may affect the balance of the gut.

Ageing
As pets age, changes naturally occur in digestion and the gut microbiota. The digestive system may become more sensitive, and the body may no longer be able to utilise nutrients as efficiently as before.
Health conditions
Recurring or prolonged digestive problems may also be associated with underlying health conditions. If symptoms persist or become worse, it is important to consult a vet to identify the cause.

Prevent digestive problems and promote gut health
Many everyday situations can disrupt the balance of the gut microbiota. Nutrolin® GUT & FLORA provides comprehensive support in a variety of situations. This multi-action paste combines probiotics, prebiotics and the omega-3 fatty acids EPA and DHA.
It can be used both to help prevent digestive problems and as part of the daily wellbeing routine of dogs and cats with sensitive stomachs.
Choose Nutrolin® GUT & FLORA when your dog’s or cat’s gut needs support
Nutrolin® GUT & FLORA uniquely combines the omega-3 fatty acids EPA and DHA from fish oil with probiotics and prebiotics. It is a tasty paste that is easy to mix into your pet’s food.
How does Nutrolin® GUT & FLORA help dog and cat?
- Supports normal gut function
- Promotes a balanced gut microbiota
- Helps maintain normal stool consistency
- Supports digestion in a variety of demanding situations
- Suitable for daily use in pets with sensitive stomachs
Nutrolin® GUT & FLORA may be particularly beneficial for pets that:
- Experience recurring digestive problems

- Are undergoing antibiotic treatment
- Travel frequently or participate in active hobbies
- Live in stressful or changing environments
- Need digestive support as they age
All the active ingredients have been carefully selected to provide comprehensive support for gut health.
Some dogs and cats need ongoing support for their gut health
Although many digestive problems are linked to specific situations, such as antibiotic treatments or changes in diet, some dogs and cats have sensitive digestive systems throughout their lives.
The signs may be familiar to many pet owners. Stool consistency varies between normal and loose, introducing new foods is difficult or almost impossible, and stressful situations immediately affect digestion. Symptoms may be mild, but they keep coming back.
Acid reflux can also be part of everyday life for pets with sensitive stomachs. In dogs especially, signs that may suggest acid reflux include repeated swallowing, lip smacking, lip licking, restlessness and eating grass. These symptoms may come and go, making them difficult to recognise.
In such cases, the aim is not necessarily to address a single episode of digestive upset, but to support gut health over the long term. Consistent support for the gut microbiota may help improve stool consistency, reduce the frequency of digestive problems and make everyday life more predictable.
Nutrolin® GUT & FLORA is also suitable for daily use when your dog’s or cat’s gut needs regular support.

Ylkä’s tummy no longer rumbles!
Ylkä, a Border Terrier, has had a sensitive stomach and symptoms of acid reflux for most of his life. The first symptoms appeared when he was just one year old. Ylkä underwent thorough veterinary examinations, including an endoscopy, but no clear cause was found.
“Ylkä has always been prone to acid reflux. He was examined and everything seemed fine, but the symptoms just wouldn’t go away,” explains his owner, Kirsi.
Kirsi trains and competes in agility with her dogs. However, Ylkä’s rumbling stomach and occasional loss of appetite made their shared hobby more difficult. A fatty acid supplement he had previously been given also seemed to make his symptoms worse.
Kirsi decided to try Nutrolin® GUT & FLORA paste, although she was initially somewhat hesitant about using a fish oil-based product.
“I noticed the difference really quickly! After the first month, his acid reflux symptoms disappeared, and since then he has only had symptoms on a couple of occasions. The change has been enormous.”
Ylkä now receives Nutrolin® GUT & FLORA paste every day, and Kirsi has no intention of stopping. His stomach has settled, and he is once again racing around agility courses with his usual enthusiasm.
Ylkä’s experience shows just how much digestive wellbeing can mean to the everyday lives of dogs and their owners.
Why are fatty acids, probiotics and prebiotics important for gut health?
Many factors contribute to a healthy gut. Probiotics, prebiotics and the omega-3 fatty acids EPA and DHA from fish oil play particularly important roles.
Nutrolin® GUT & FLORA combines all three in one supplement, providing comprehensive support for gut health.
Where do dogs and cats get the fatty acids they need?
Research has shown that high levels of EPA and DHA from fish oil or microalgae oil can help regulate inflammation (e.g. Calder, 2017; Serhan & Levy, 2018). Although not all digestive symptoms are caused by inflammation in the gut, these fatty acids may help alleviate symptoms. An adequate intake of EPA and DHA supports normal gut function.
Salmon oil is one of the best-known sources of EPA and DHA. However, its omega-3 content has declined significantly during the 21st century. This change is largely due to the increasing use of rapeseed oil instead of fish oil in salmon farming feeds. As a result, salmon oil is no longer the most sensible choice when high levels of marine omega-3 fatty acids are required.
To provide a dog or cat with a sufficient amount of EPA and DHA, more than four times as much salmon oil would be needed compared with a high-quality fish oil supplement. For this reason, a high-quality fish oil or microalgae oil rich in EPA and DHA is generally the better option.
Plant oils also contain omega-3 fatty acids, but they do not function in the same way as marine omega-3s and do not help regulate inflammatory. The most common omega-3 fatty acid in plant oils is alpha-linolenic acid (ALA). While ALA can be converted into EPA, the conversion rate is extremely low. Therefore, plant oils cannot replace the omega-3 fatty acids found in fish oil.
Probiotics support the gut microbiota
Probiotics are live, beneficial microorganisms that help maintain a balanced gut microbiota.
Nutrolin® GUT & FLORA contains the probiotic strain Enterococcus faecium (DSM 10663/NCIMB 10415), also known as SF68. It is one of the most extensively studied probiotic strains used to support digestion in pets.
The European Food Safety Authority (EFSA) has assessed this strain for use as a gut flora stabiliser in dogs and cats. Research has shown that it can support stool quality and the body’s natural defence mechanisms. (European Commission, 2015; Benyacoub et al., 2003)
Probiotics can be beneficial as part of everyday gut care, but they may be particularly useful during dietary changes, while travelling, during or after antibiotic treatments and in other situations that cause stress.
Prebiotics nourish beneficial gut bacteria
In addition to probiotics, prebiotics play an important role in promoting gut health.
Prebiotics provide nourishment for beneficial gut bacteria. They help create an environment in which these bacteria can thrive and multiply.
Nutrolin® GUT & FLORA contains several prebiotic ingredients, including mannan-oligosaccharides (MOS), fructo-oligosaccharides (FOS), fructans, beta-glucan and chitin. Together, they provide versatile support for the gut microbiota.
Together, they offer more than the sum of their parts
Probiotics, prebiotics and omega-3 fatty acids support gut health in different ways.
Probiotics help replenish beneficial microorganisms; prebiotics provide nourishment for them, and the omega-3 fatty acids EPA and DHA support normal bodily and intestinal function. It is therefore reasonable to suggest that combining these nutrients may offer broader support than any one ingredient alone.
This is what makes Nutrolin® GUT & FLORA so effective. It provides threefold support for gut health, making it a versatile choice for promoting digestive wellbeing in dogs and cats.

When should you consult a vet?
Mild, temporary digestive problems are sometimes part of life for dogs and cats. However, prolonged or severe symptoms may indicate an underlying condition that requires veterinary examination and treatment.
Contact your vet if your dog or cat:
- Has diarrhoea for several consecutive days
- Vomits repeatedly
- Has blood in their stools or passes black stools
- Loses their appetite
- Loses weight without an obvious reason
- Appears lethargic or in pain
- Experiences recurring digestive problems
- Develops sudden symptoms or symptoms that worsen rapidly
Veterinary assessment is particularly important for puppies, kittens and older pets, as well as when symptoms are accompanied by signs of dehydration or a deterioration in general condition.
The earlier a potential illness is identified, the sooner appropriate treatment can begin.
Frequently asked questions
Yes. Nutrolin® GUT & FLORA is designed for daily use to support normal gut function in dogs and cats. Many owners use it continuously, particularly for pets with sensitive stomachs or during situations that may place extra strain on the digestive system.
Yes. Nutrolin® GUT & FLORA is suitable for both puppies and kittens. Supporting gut health is particularly important during dietary changes, moving to a new home or other potentially stressful situations.
Yes, and we recommend it. Antibiotics can also affect beneficial gut bacteria, so supporting gut health during and after a course of antibiotics is worthwhile.
If your pet has a serious illness or is taking several medications, consult your vet before use.
The time it takes to notice a difference varies from one pet to another. In some dogs and cats, changes in stool consistency or digestive function may become noticeable within a few days. For others, restoring a balanced gut may take several weeks.
The best results are generally achieved through regular, long-term use.
Sometimes digestive problems appear in ways other than diarrhoea or vomiting. A dog or cat may eat more grass than usual, smack or lick their lips, have a poor appetite or seem restless for no obvious reason.

Rescue dog Buster found a loving home and relief from digestive problems
Meet Buster, a rescue dog who moved from Greece to Finland.
Buster did not have the easiest start in life. Before finding his own home, he wandered the streets, searching for food in rubbish bins. Eventually, his luck changed, and Buster found a loving family and a new life in Finland.
His years on the streets may also have taken a toll on his digestive system. Unexplained digestive problems, symptoms of acid reflux and occasional nausea affected his everyday life. One possible contributing factor was the strain of having to adapt to a highly variable diet over the years.
Buster’s owner decided to try Nutrolin® GUT & FLORA to support his gut health.
After a few weeks, changes began to appear. His digestive symptoms settled, and his overall wellbeing improved. His owner also noticed an unexpected additional benefit: training became easier as Buster seemed calmer and better able to concentrate.
Buster’s story is a reminder of how much a healthy gut can contribute to an animal’s everyday wellbeing.
A healthy gut helps your pet feel better
Gut health affects much more than digestion alone.
A balanced gut microbiota supports nutrient absorption, the body’s natural defence mechanisms and your pet’s overall wellbeing. This is why it is worth paying attention to gut health before digestive problems become part of everyday life.
While some digestive symptoms are linked to specific situations, such as changes in diet, travelling or antibiotic treatments, some dogs and cats need ongoing support for their gut health.
Carefully selected nutrients can help maintain normal gut function, promote healthy stool consistency and support digestive balance.
Nutrolin® GUT & FLORA combines probiotics, prebiotics and the omega-3 fatty acids EPA and DHA from fish oil in one supplement.
A healthy gut often means better overall wellbeing, more consistent digestion and, quite simply, a happier pet.
