Lactobacillus rhamnosus

Lactobacillus rhamnosus is a type of bacteria found in the normal gut microflora in humans. Its main role is to produce the enzyme lactase. This enzyme breaks down the sugar lactose, which is found in dairy, into lactic acid.

Lactobacillus rhamnosus is considered to be particularly important for female intimate health as certain L. rhamnosus strains also colonise in the vaginal environment. 

Lactobacillus rhamnosus has numerous benefits and uses for the digestive system. It helps prevent or treat various types of gastro-intestinal infections and diarrhea. It also helps stimulate the immune system responses and helps prevent certain allergic symptoms.

Food sources rich in Lactobacillus rhamnosus

Lactobacillus rhamnosus can be often found in a variety of fermented dairy products such as yogurt, cheeses, milk, and other dairy products.

Fermented cabbage is rich in friendly bacteria, including several strains of Lactobacillus.

Kefir grains are a combination of lactic acid bacteria and yeast, fermented into a thin drink. Its precise microbial composition varies, but L. rhamnosus is always present.

Lactobacillus rhamnosus is also available as a probiotic supplement.
