Lactobacillus Brevis
Also known as: Lactobacillus brevis, L. brevis, Probiotic strain (generic)
Overview
*Lactobacillus brevis* is a species of lactic acid bacteria naturally found in fermented foods and the human gut. As a probiotic, it's explored for potential health benefits, particularly in gut health and immune support. This bacterium is known for its resilience in acidic environments and its production of beneficial compounds. While research is ongoing, initial findings suggest it may improve gut barrier function and reduce inflammation. It is available in various forms, including capsules and fermented foods. The current evidence base is still developing, necessitating further research to fully understand its clinical applications and benefits.
Benefits
*Lactobacillus brevis* shows promise in improving gut barrier function and reducing inflammation, potentially benefiting conditions like inflammatory bowel disease (IBD). A study indicated that both live and pasteurized forms of *L. brevis* IBRC-M10790 could enhance tight junction proteins, with pasteurized forms showing higher protective effects. Limited evidence suggests potential oral health benefits by reducing caries-related acidogenicity. Additionally, the *L. brevis* 47 f strain has shown protective effects against experimental mucositis in mice. However, more research is needed to quantify effect sizes and determine the duration of these benefits.
How it works
*Lactobacillus brevis* primarily works by modulating the immune system and enhancing intestinal barrier function. It interacts with the gut microbiota and epithelial cells, potentially improving barrier integrity. The mechanism involves upregulating tight junction proteins like ZO-1, Occludin, and E-cadherin. While specific absorption and bioavailability data for *L. brevis* are limited, probiotics generally survive passage through the stomach and small intestine to reach the colon, where they exert their beneficial effects.
Side effects
As a probiotic, *Lactobacillus brevis* is generally considered safe, but specific safety data are limited. Common side effects typically include mild gastrointestinal symptoms like bloating or gas. Uncommon and rare side effects are not well-documented for *L. brevis* specifically, but serious adverse effects, such as infections, are possible in immunocompromised individuals. Drug interactions are not well-studied. Probiotics are generally contraindicated in severe immunocompromised states. Caution is advised in pregnant women and immunocompromised individuals. Consult a healthcare provider if you experience any adverse effects.
Dosage
An effective dose of *Lactobacillus brevis* has not been definitively established. Typical probiotic dosages range from 1-10 billion CFU per day, but specific recommendations for *L. brevis* are lacking. The maximum safe dose is also not well-defined. It is often taken with meals to enhance survival through the stomach. *L. brevis* is available in various forms, including capsules and fermented foods. Survival through the stomach and small intestine is crucial for probiotic efficacy. Consult with a healthcare provider for personalized dosage recommendations.
FAQs
How should I store *Lactobacillus brevis*?

When is the best time to take *Lactobacillus brevis*?
Typically taken with meals to enhance survival through the stomach and improve its effectiveness.
What results can I expect from taking *Lactobacillus brevis*?
Potential benefits to gut health, but individual results may vary. It is not a cure-all but can be a supportive supplement.
Research Sources
- https://pmc.ncbi.nlm.nih.gov/articles/PMC11234635/ – This study investigated the effects of *L. brevis* IBRC-M10790 on intestinal barrier function. The research found that both live and pasteurized forms of the bacteria improved intestinal barrier function by enhancing tight junction proteins. Interestingly, the pasteurized form showed higher protective effects, suggesting a potential mechanism beyond live bacteria activity.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC11985112/ – This study examined the effect of *L. brevis* CD2 on acidogenicity in sugar-exposed bacteria. The findings suggest that *L. brevis* CD2 has the potential to reduce acid production, which could be beneficial for oral health by reducing the risk of dental caries. This indicates a possible application of this probiotic strain in maintaining oral hygiene.
- https://www.mdpi.com/2076-2607/8/6/876 – This research focused on the *L. brevis* 47 f strain and its protective effects against experimental mucositis in mice. The study demonstrated that *L. brevis* 47 f could protect against mucositis, indicating potential protective effects on the gut. This suggests a possible therapeutic role for this strain in managing conditions that cause intestinal inflammation.
- https://www.tandfonline.com/doi/full/10.1080/2314808X.2024.2324409 – This study investigates the impact of *L. brevis* on gut health and immune response. The research highlights the potential of *L. brevis* in modulating the gut microbiota and enhancing immune function. The findings suggest that *L. brevis* could be a valuable probiotic for improving overall gut health and supporting the immune system.
- https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2812728 – This meta-analysis provides a comprehensive overview of probiotic use and its effects on various health outcomes. While it doesn't focus solely on *L. brevis*, it offers valuable insights into the general efficacy and safety of probiotics. The study emphasizes the importance of strain-specific research to fully understand the benefits and limitations of different probiotic species.
