Our friendly bacteria research

Every strain in our friendly bacteria range has been selected because of the research behind it. All of our strains have been researched for safety and for their ability to survive stomach acid, so they reach the gut, or the vagina, alive.

How are our strains researched?

Research usually happens in two stages:

  • In the lab - “in-vitro” studies test how strains behave in controlled conditions, such as how well they survive acidic environments.

  • In people - where possible, strains are also studied in “in-vivo” trials with human volunteers.

  • For members of the public: information on probiotics, their uses, and the research behind them can be found in the Probiotics Learning Lab.
