Classified as a Gram-positive bacteria, Lactobacillus reuteri uses, as its name suggests, lactose as an energy source.
Lactobacillus reuteri produces antimicrobial substances (reuterin and reutericyclin), molecules that inhibit the development of pathogenic bacteria such as Escherichia coli (Gram-negative) or other bacteria, these Gram-positive, that seek to colonise the intestinal flora.
Lactobacillus reuteri is also active against parasites (Cryptosporidium parvum) and rotaviruses that can cause severe diarrhoea. Lactobacillus reuteri therefore contributes to digestive well-being.
This bacterial strain is implanted in infants during breastfeeding and therefore contributes very early to the constitution of the child's microbiota. In addition, Lactobacillus reuteri has beneficial effects on cardiovascular health. Indeed, the action of this bacterium helps to reduce the levels of "bad cholesterol" in the blood (LDL), which gives it a protective role in the heart and blood vessels.
