How it works

Antibiotics kill harmful bacteria, but they also kill bacteria that help keep you well.

When beneficial bacteria they are eradicated as a consequence of antibiotic use, pathogens have the opportunity to multiply and even cause infections.

Antibiotic-associated diarrhea (AAD) is a direct consequence of the killing of good bacteria  and the most common side effect of antibiotic use.

Bio-K+ Antibiofix steps in for their protective action to help prevent AAD and even life-threatening infections like C. difficile.
