Lactobacillus reuteri is a type of beneficial bacteria classified as a probiotic, naturally found in the human gut, mouth, and other body areas. It belongs to the Lactobacillus genus and is recognized for its potential health contributions when consumed through specific foods or supplements.
This bacterium plays a role in maintaining a balanced microbiome, which is the community of microorganisms in the body. Lactobacillus reuteri is most beneficial for supporting digestive health, including helping to alleviate symptoms of diarrhea, particularly in children, and aiding recovery after antibiotic use. It may also contribute to reducing the duration of common infections like rotavirus diarrhea.
Research indicates that certain strains of Lactobacillus reuteri might offer additional benefits, such as improving cholesterol levels in some individuals and supporting immune function. It is sometimes used to address infant colic, though evidence varies. The effectiveness can depend on the specific strain and the amount consumed.
Common forms include capsules, powders, and drops, often containing strains like DSM 17938 or ATCC PTA 4659. It is generally considered safe for most people when taken as directed, though individual responses may vary.
Effectiveness and Risk Overview
Condition | Effectiveness | Details |
|---|---|---|
| Gut Dysbiosis | Lactobacillus reuteri is a probiotic strain that helps restore the balance of gut microbiota, improving gut health and function. | |
| Immune System Support | Lactobacillus reuteri has immunomodulatory effects, enhancing the body's immune response and potentially reducing the severity of infections. | |
| Gut Microbiome Imbalance | As a probiotic, Lactobacillus reuteri colonizes the gut and promotes a healthy microbiome, which is essential for overall digestive health. | |
| Gut Barrier Function | Lactobacillus reuteri helps maintain the integrity of the gut barrier, preventing leaky gut syndrome and associated conditions. | |
| Irritable Bowel Syndrome (IBS) | Studies have shown that Lactobacillus reuteri can alleviate symptoms of IBS, such as bloating and abdominal pain, by modulating the gut microbiota. | |
| Inflammatory Bowel Disease | Lactobacillus reuteri has been shown to reduce inflammation and improve symptoms in models of inflammatory bowel disease, suggesting potential benefits for conditions like Crohn's disease and ulcerative colitis. | |
| Bone Density Loss | Some studies suggest that Lactobacillus reuteri can improve bone density, potentially reducing the risk of osteoporosis, by modulating the gut-bone axis. |
