Antibiotics are essential for fighting harmful bacteria, but they don't discriminate — they also wipe out large portions of the beneficial bacteria that keep the gut microbiome balanced.

This disruption, or dysbiosis, is what commonly leads to antibiotic-associated diarrhoea (AAD), bloating, and digestive discomfort, sometimes appearing weeks after a course of antibiotics has ended.

OMNi-BiOTiC® 10 AAD is a multispecies probiotic formulated by Institut AllergoSan (Graz, Austria) — a company built on more than 30 years of gut microbiome research and over 100 clinical studies on its probiotic formulas, and now recognized as one of the top probiotic brands worldwide.

The formula delivers 10 scientifically selected, human-derived bacterial strains that colonize the intestine from top to bottom, helping to sustainably re-establish a healthy, diverse microbiome even while antibiotics are still being taken.

Its strain combination has been studied for its ability to help crowd out opportunistic pathogens such as Clostridium difficile and reduce the toxins they release.

Research published in Nutrients has also examined how this specific 10-strain co-culture and its postbiotic compounds interact with the gut environment, while independent studies have looked at its role in reducing digestive discomfort following procedures like colonoscopy.

Each sachet supplies at least 5 billion live organisms (10 billion at the full daily dose), combined with prebiotic fibres (inulin, FOS) that help nourish the bacteria as they establish themselves.

The formula is free from animal protein, gluten, yeast, and lactose, making it suitable for those with milk allergies, and appropriate for children and use during pregnancy or breastfeeding (under guidance from a healthcare provider).
