Bacillus subtilis

Bacillus subtilis is a hardy, spore-forming probiotic that plays a key role in breaking down food, improving nutrient absorption, and reinforcing a dog’s gut barrier against pathogens. Known for its ability to outcompete harmful bacteria, it supports digestive stability, reduces inflammation, and may help prevent chronic gastrointestinal issues like diarrhea or Small Intestinal Bacterial Overgrowth (SIBO). Its natural presence in soil and fermented foods reflects its evolutionary role in canine digestive health.
