Lactobacillus rhamnosus
Quick Summary
Lactobacillus rhamnosus is a type of rod-shaped, gram-positive bacteria that produces lactic acid as a byproduct of metabolism. These bacteria are commonly found in fermented foods like yogurt and cheese, and are also a natural part of the human microbiome.12
L. rhamnosus is often used as a probiotic, which are live microorganisms that may offer health benefits, particularly for gastrointestinal issues. Certain strains, like L. rhamnosus GG, have shown modest effects in reducing the duration of infectious diarrhea and may help prevent antibiotic-associated diarrhea. While generally safe, they can pose risks to individuals with compromised immune systems.2
