How Lactobacillus Reuteri works
Lactobacillus reuteri is a probiotic.
It supports the digestive system by establishing itself in the gut lining and becoming a key player in the resident microbiome. This enables it to compete for space and nutrients and prevent the overgrowth of harmful bacteria. Lactobacillus reuteri produces antimicrobial compounds, such as reuterin and reutericyclin. These compounds can inhibit the growth of harmful bacteria and fungi, ensuring a balanced gut environment.
