Mutaflor Probiotic – Escherichia coli strain Nissle 1917

Mutaflor® is a probiotic supplement featuring Escherichia coli Nissle 1917 — a unique, non-pathogenic human strain with over a century of documented use. First discovered in the trenches of World War I, it was isolated from a soldier who remained unaffected by dysentery while others around him fell ill. This exceptional strain, still in use today, has since been studied extensively for its ability to support a healthy intestinal environment.

Registered at AUST R level in Australia, Mutaflor® is indicated for the relief and management of chronic constipation. It is the only probiotic in the country to hold this status, reflecting its rigorous assessment for quality, safety, and efficacy.

Key Features

• Clinically recognised strain — One of the most studied probiotics globally, used for over 100 years in gut health.

• Strain-specific activity — May support microbial balance, gut barrier function, and the natural regulation of bowel function.

• Enteric-coated delivery — Capsules are designed to bypass the stomach and dissolve in the colon, where EcN can thrive.

• Cold chain protected — Stored between 2–8 °C for stability; shipping includes temperature control.

Who Might Consider Mutaflor®?

Mutaflor® may suit individuals seeking to support gut health and bowel regularity, particularly those under the care of a healthcare practitioner for chronic constipation. Its unique mode of action also makes it a candidate in protocols addressing microbiome imbalances or dysbiosis. The strain’s ability to colonise, support mucosal function, and produce important metabolites may complement other gut-focused approaches.
