Bacillus subtilis
Evidence Level
Moderate
1 Clinical Trial
3 Documented Benefits
3/5 Evidence Score

DE111® is a spore-forming Bacillus subtilis probiotic from ADM Deerland, prized for surviving heat, acid, and shelf storage that destroy many probiotics. Studied for digestive regularity and immune balance, the hardy spores germinate in the gut after being swallowed.

Studied Dose Commonly 1 billion CFU per day.
Active Compound Bacillus subtilis DE111, a spore-forming probiotic strain.

Benefits

Digestive regularity

In clinical research, Bacillus subtilis DE111 supported a more normal, regular bowel pattern in healthy people.

Gut microbiome balance

The spores germinate in the intestine and support a healthier balance of gut bacteria.

Immune support

Research on DE111 observed favorable shifts in immune-cell activity, reflecting the gut-immune connection.

Mechanism of action

1

Spore survival and germination

As spores, DE111 survives stomach acid and heat, then germinates into active bacteria in the small intestine within hours of being swallowed.

2

Microbiome and gut-barrier support

DE111 supports a balanced microbiome and the gut environment, which underpins both digestion and immune function.
