Saccharomyces boulardii (S. boulardii) is a yeast that occurs naturally in the human digestive system.

Acidic environments, high temperatures, bile, and digestive enzymes do not deactivate it, which means it can reach the intestines alive.


S. boulardii CNCM I-745 can survive the harsh conditions of the stomach. This makes it useful as a probiotic.

Saccharomyces boulardii  

A helpful probiotic

Saccharomyces boulardii is a beneficial yeast-based probiotic known for its ability to support digestive health. As a probiotic supplement, Saccharomyces boulardii aids in maintaining a balanced intestinal environment by crowding out harmful bacteria, thereby promoting a healthy gut flora. It works by reinforcing the gut barrier, which can be particularly beneficial in cases of antibiotic-associated diarrhea, traveler's diarrhea, or digestive disturbances.

Probiotics, including Saccharomyces boulardii, contribute to overall health by supporting a robust immune system, reducing inflammation, and potentially enhancing nutrient absorption. Incorporating probiotics into one's routine can be advantageous for individuals seeking to fortify their gut health and bolster their body's natural defences against digestive issues and immune-related concerns.

Carmen Kelly
Great supply

If you're already convinced of the advantages offered by a complex like this and are certain it's the appropriate supplement for you, then opting for this strength is a wise choice. While it's suggested to consume a minimum of one tablet per day, with a maximum of three, I find that one tablet daily at this potency level suffices for my needs. This means they'll last approximately three months, offering good value for money as well.

Niall Hill
Great product, actually works!

The product works great, I have taken this for a while now and started feeling it's effects from the first day. Do recommend it to anyone looking to protect and improve their gut health.

Frank Davis

I read about this type of probiotic as being especially good if you’ve taken antibiotics. I took one a day and after a fortnight days my stomach is back to normal.

Adriana Sutton
Will continue to take. Great purchase

Samuel Ward
Daily essential

A really good bacteria. The more I read the more I come to the conclusion that a healthy gut biome is essential for my health. I take in the morning along with my morning yoghurt to help my gut health.
