Overview

Bacillus clausii is a beneficial, spore-forming bacterium that is commonly used as a probiotic. Its ability to form spores allows it to survive the acidic environment of the stomach and reach the intestines, where it can help to restore the balance of the gut microbiota. It is often used to treat and prevent diarrhea, including antibiotic-associated diarrhea.

Key Benefits

Treats and Prevents Diarrhea

Bacillus clausii has been shown to be effective in treating and preventing various types of diarrhea, including acute infectious diarrhea and antibiotic-associated diarrhea.

Supports Gut Health

Modulates the Immune System

Bacillus clausii can help to modulate the immune system, which may be beneficial for individuals with allergies and other immune-related conditions.

Produces Antimicrobial Substances

It produces antimicrobial substances that can help to inhibit the growth of harmful bacteria in the gut.

Dosage & How to Take

The recommended dosage of Bacillus clausii can vary depending on the specific product and the condition being treated. It is typically taken in doses of 2-6 billion CFU (colony-forming units) per day for adults.
