For Those On Antibiotics is designed to be taken during courses of antibiotic medication. The three strains in the product have been shown to survive to reach the gut alive, even during a course of antibiotics. It’s recommended to take 1 capsule daily with breakfast, and there is no need to take this probiotic at a different time of the day from the antibiotic. These strains should help to protect the resident gut bacteria and reduce the incidences of antibiotic-associated side effects.
