What it is

Lactobacillus rhamnosus is a type of bacteria that is naturally found in the human gut. It is often used as a probiotic, meaning it is a live microorganism that may provide health benefits when consumed in adequate amounts. It is typically grown in a laboratory setting using specific nutrient-rich media.

Why it's used

Lactobacillus rhamnosus is added to foods as a live culture to provide probiotic benefits. It is often found in fermented foods like yogurt and kefir, as well as in dietary supplements and some beverages. Manufacturers include it to potentially support gut health.

Health notes

Lactobacillus rhamnosus is generally recognized as safe (GRAS) by the FDA for use in food. Research suggests that certain strains may help with digestive issues and support immune function, though effects can vary by strain and individual. International bodies like EFSA have also evaluated probiotics, but specific health claims require robust scientific backing. Evidence for specific health benefits is still evolving and not universally agreed upon.

Allergen info

Lactobacillus rhamnosus is not a major allergen. It is a bacterium and does not contain gluten.
