Why are PrecisionBiotics® special? 

Over 17 years ago, our scientists began researching thousands of bacterial cultures together with experts from one of the world's leading centres of microbiome research. 

Our PrecisionBiotics are unique bacterial cultures that we have discovered, developed and then rigorously tested, including in human clinical trials, to ensure they have the precise qualities needed and that they meet our rigorous standards.

All our products contain bacteria that occur naturally in the human gut and are at home there.

The 1714-Serenitas culture is one of the first cultures to have shown in a clinical study to increase the activity in the areas of your brain that are associated with emotions, learning and memory1. It was also associated with a higher ability to cope with stress during a stress test1.

PrecisionBiotics scientists have developed a convenient, once daily formulation, specially designed to reach the human gut with its properties intact. No refrigeration required.
