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.

pill

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.

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.

What exactly is your microbiome and why is it important?

I have heard "prebiotic" and "probiotic" foods are good for my gut. Is this true and what does this mean?

When is it appropriate to take a supplement for gut health?

What is Seenbyo synbiotic duo cap?

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.

What are the active ingredients in the synbiotic duo cap?
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.
