Seenbyo synbiotic duo cap. is the meeting point of science and simplicity. 30x more effective than a standard capsule, its unique capsule-in-capsule design ensures targeted delivery of ingredients within the gut, where the microbiome thrives.
The transparent outer shell is designed to break down in your stomach, releasing fructooligosaccharides (FOS) fibre, which act as food for the live bacteria. It also contains Vitamin D3, Biotin and Zinc, all of which have been included for their role in supporting a healthy gut.
outer
Not visible to the naked eye, within the green inner capsule are 50 billion live bacteria. Protected by the outer shell as it makes its way through the stomach, this inner capsule is able to continue through the gastro-intestinal tract, breaking down in the intestines and releasing the live cultures into your gut microbiome.

What is unique about this capsule?
What can I expect from taking the synbiotic duo cap?
Is the synbiotic duo cap a probiotic?
The capsule contains live bacteria, therefore it can be considered a probiotic. It also contains fructooligosaccharides (FOS) which can be considered prebiotics. However, we refrain from using such terms as UK Law prevents this, seeing our products as food supplements to which no health claims can be associated.
How long do I need to take the synbiotic duo cap for?
We recommend taking one capsule a day for a minimum of 3 months. This is how long your microbiome needs to adjust to the new bacteria, as also recommended by the British Society of Gastroenterology to anyone trying a new bacterial product.
Can I take other supplements alongside this for my gut or is Seenbyo enough?
The synbiotic duo cap has been designed to provide one potent dosage of 50 billion live bacteria in one capsule, from 11 unique strains, alongside other vitamins and minerals that support overall gut health. Therefore as far as live bacteria supplements go, our synbiotic duo cap should be enough.
What are the active ingredients in the synbiotic duo cap?
Our capsule combines live bacteria with other vitamins and minerals for added digestive value. See the full nutritional information table for more information.
Are there any side effects from taking the synbiotic duo cap?
Our gut microbiome is as unique as our fingerprint, therefore your experience with our products will be unique to you. Whilst there should be no adverse effects, some people have reported experiencing an upset stomach, gas, diarrhea, or bloating. Those symptoms usually go away after your body gets used to the bacteria in the synbiotic duo cap (usually within 1-4 weeks).
Other than my gut, will I find any other benefits to taking Seenbyo?
Seenbyo is officially classed as a food supplement by UK law, and therefore we cannot legally claim specific health benefits ourselves. We encourage you to do your research.
What exactly is your microbiome and why is it important?
What exactly is your microbiome? It's a complex community of over 38 trillion microorganisms living in and on your body. Interestingly, there are more microbes than there are human cells in your body.
So it is important that we look at our microbiome, as it affects everything from digestion to the immune system, hormones, skin health, and mental well-being.
Each of these connections is vital. For instance, the gut-brain axis can influence mood and cognitive function, while gut microbes can impact skin health, digestion efficiency, immunity, and hormonal balance.

When is it appropriate to take a supplement for gut health?
While a balanced diet is critical to good health, there are times when supplements can play a vital role in maintaining gut health.
Our daily choices – what we eat, our stress levels, sleep patterns, and even our physical activity – can significantly impact the balance of our gut.
Supplements can fill nutritional gaps, especially in today's fast-paced world, where eating a perfect diet is only sometimes feasible.

The importance of a healthy gut microbiome.
Our gut bacteria play an incredibly complex and critical role in helping us thrive. The microbiome affects everything from digestion to the immune system, hormones, skin health and even mental wellbeing.

our unique formulation.
Our capsule contains 11 unique bacterial strains from 7 different species. They have each been carefully selected and are all trademarked and registered. In amongst them, we are proud to include Lactobacillus acidophilus NCFM, the world's most researched strain of acidophilus.
Paired with FOS fibre and key nutrients, all contained within our state-of-the-art duo cap, we ensure the targeted delivery of ingredients to the right place, at the right time.
15 active ingredients.
Fructooligosaccharides (FOS) act as the food and energy source for the live bacteria in our capsule. Housed within the liquid layer, it is released first to support the function of the live inner core.
READ MORE ON FOS
Contributes to the normal function of the immune system and the maintenance of normal muscle function. It plays a role in cell division, which is essential for maintaining the integrity of the gut lining.
READ MORE ON VIT D
Contributes to the normal function of the immune system. A well-functioning immune system is crucial for gut health, as much of our immune system is in the gut.
READ MORE ON ZINC
Vital for maintaining mucosal health, which is an integral part of a healthy gut. Maintaining mucosal integrity helps support the gut's natural barrier and its functions.
