How Does Bimuno® Work?

Bimuno® is a non-digestible fibre supplement that passes through the upper gastro-intestinal tract intact until it reaches the colon. Here the good bacteria ferment the galactooligosaccharides (GOS) in Bimuno, stimulating their own growth which leads to competition for space with bad bacteria in the gut. The more space taken up by good bacteria, the less space there is for bad bacteria.

Bimuno selectively targets bifidobacteria, which is a type of good bacteria that digests fibre and other complex carbohydrates that your body can’t digest on its own. Unlike many other beneficial bacteria, bifidobacteria does not produce gas.

When taken daily, Bimuno is scientifically proven to grow levels of bifidobacteria within just 7 days*. However it’s important to note everyone’s gut microbiome is different and could react differently so the timing and degree of change may vary.

How will I know if Bimuno is working?

As we are all unique, with our own make up of gut bacteria, it’s difficult to determine a clear indication that Bimuno is working. The human body is extremely complex and we all respond differently to what we ingest in our daily diets, whether it’s food, drink, supplements, or medications.

The gut microbiota often plays a major role in our general health, immunity and even influences the functioning of the brain. Encouraging the growth of good gut bacteria through diet, helps maintain a balance of bacteria in the gut.

What to expect when taking Bimuno

Day 1-3 When you take Bimuno for the first time, it will take 3 days to start feeding your bifidobacteria.

Day 4-7 You might feel some slight gurgling in your tummy. This is a good sign as it means Bimuno is beginning to reset your microbiota (the bacteria in your gut).

Day 8-14 Your microbiota has now changed and Bimuno is feeding and nurturing your beneficial bacteria.

Don’t stop after 14 days. Make Bimuno part of your daily routine and continue to feed your good gut bacteria.
