The United kingdom's most popular and respected brand
OptiBac specialises entirely in live cultures and are considered experts in the field. Their strains are of the highest quality; each strain undergoes tests to ensure it is stable at room temperature, can survive stomach acidity, and can adhere to the lining of the gut wall.
Their focus in particular is on taking specific strains and targeting specific health conditions - acknowledging the fact that different species and strains have different effects on the body.
Optibac is completely transparent when it comes to the make-up of our products, and unlike many others, they cite not only the microorganism's family and species, but the strain (the specific type) as well.
