How it works
As a probiotic, Bacillus clausii colonizes the intestines, competing with pathogenic bacteria and producing antimicrobial substances. Its spore form allows it to survive gastric acidity and reach the intestines intact, where it exerts its beneficial effects.
Who should take it
Adults looking to address bloating, indigestion, irregular bowel movements. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.
Avoid / careful
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.

About Bacillus clausii
Bacillus clausii is a probiotic supplement used to support digestive comfort and gut-barrier integrity. Spore probiotic for antibiotic-associated diarrhoea. It is available in capsule form and dosed for adults in India and internationally. As a western-tradition entry in the SacredBod catalog, it is positioned as a single-ingredient option that can be used on its own or layered into a broader protocol. Bacillus clausii works through the mechanisms characteristic of its class — see the mechanism and research sections for detail. It primarily acts on the gut, intestines, stomach, and effects are dose-dependent, typically becoming measurable within 1-4 weeks for digestive comfort. Consistency matters more than dose size for this category.
Evidence
Bacillus clausii carries an evidence grade of B in the SacredBod catalog, reflecting good-but-limited human evidence for digestive comfort and gut-barrier integrity. Spore probiotic for antibiotic-associated diarrhoea. Benefits are cumulative rather than immediate, typically becoming noticeable within 1-4 weeks for digestive comfort, and individual response varies.
Dosing
A typical dose is 2 billion CFU, taken with food, usually in the morning. Start at the lower end, assess tolerance, and stay consistent; more is not automatically better.
Cautions
