Bifidobacterium lactis B55
Also known as: Bifidobacterium lactis, Bifidobacterium animalis subspecies lactis, probiotic strain, Bifidobacterium lactis B55
Overview
Bifidobacterium lactis B55 is a specific strain of *Bifidobacterium lactis*, a beneficial bacterium naturally found in fermented foods and the human gut. It is classified as a probiotic supplement, primarily utilized for its potential to support gut health and immune function. This strain is recognized for its resilience, capable of surviving the harsh acidic environment of the stomach and the digestive processes of the small intestine to reach the colon, where it can exert its beneficial effects. While *Bifidobacterium lactis* in general has been extensively studied, research specifically on the B55 strain is moderate, with a need for more focused studies to fully elucidate its unique properties and efficacy. The available evidence, though often pertaining to *Bifidobacterium lactis* as a species, suggests a role in modulating the gut microbiota and enhancing overall gastrointestinal well-being.
Benefits
Bifidobacterium lactis B55 is primarily recognized for its potential to support gut health, including the reduction of gastrointestinal symptoms like abdominal pain, and to improve immune function. While specific effect sizes for the B55 strain are not well-documented, general probiotic effects can be clinically significant in alleviating digestive discomfort. Secondary benefits may include improvements in exercise performance and a reduction in inflammation, though the evidence supporting these effects is less robust and requires further investigation. Infants and children may particularly benefit from *Bifidobacterium lactis* due to its potential role in supporting healthy gut development and immune system maturation. Benefits from supplementation may be observed within weeks, though long-term effects and the full scope of benefits for this specific strain warrant more dedicated research.
How it works
Bifidobacterium lactis B55 exerts its beneficial effects primarily by modulating the gut microbiota, promoting a healthier balance of beneficial bacteria in the gastrointestinal tract. It enhances the gut barrier function, which is crucial for preventing the passage of harmful substances from the gut into the bloodstream. Furthermore, this probiotic strain interacts with the immune system, influencing immune responses within the gut and potentially systemically. While specific molecular targets for the B55 strain are not fully identified, probiotics generally impact cytokine production and maintain gut barrier integrity. Unlike traditional nutrients, probiotics are not absorbed into the bloodstream but rather colonize the gut, where they establish a presence and exert their effects locally.
Side effects
Bifidobacterium lactis B55 is generally considered safe for most individuals. The most common side effects are mild gastrointestinal symptoms such as bloating, gas, or mild abdominal discomfort, especially when first starting supplementation. These symptoms are typically transient and resolve as the body adjusts. Uncommon side effects may include allergic reactions, though these are rare. In severely immunocompromised individuals, there is a very rare risk of infection, and caution is advised in critically ill patients or those with compromised gut integrity. There are no significant drug interactions reported for *Bifidobacterium lactis* B55. However, individuals with severe immunocompromised states are advised against its use. It is always recommended to consult a healthcare provider before starting any new supplement, especially for individuals with underlying health conditions or those who are immunocompromised.
Dosage
For general health benefits, the optimal dosage range for Bifidobacterium lactis B55 typically falls between 5 to 20 billion Colony Forming Units (CFU) per day. A minimum effective dose is often considered to be 1-10 billion CFU daily. The maximum safe dose is not well-defined, and doses exceeding 20 billion CFU per day are less commonly studied in clinical trials. To enhance the survival of the probiotic through the acidic environment of the stomach, it is generally recommended to take *Bifidobacterium lactis* B55 with food. Common forms of supplementation include capsules or powders. The efficacy of the supplement is highly dependent on the survival of the live bacteria through the digestive tract to colonize the gut. No specific cofactors are required for its absorption or activity.
FAQs
How should I store Bifidobacterium lactis B55?
To maintain the viability of the live bacteria, it is best to store Bifidobacterium lactis B55 in a cool, dry place, away from direct sunlight and moisture. Some formulations may require refrigeration; always check the product label for specific storage instructions.
Is Bifidobacterium lactis B55 safe for everyone?
Bifidobacterium lactis B55 is generally safe for most healthy individuals. However, if you are severely immunocompromised or critically ill, it is crucial to consult a healthcare provider before taking this supplement due to a rare risk of infection.
When is the best time to take Bifidobacterium lactis B55?
It is generally recommended to take Bifidobacterium lactis B55 with meals. Taking it with food can help protect the probiotic bacteria from stomach acid, increasing their survival rate and improving their ability to reach the intestines where they exert their beneficial effects.
What kind of results can I expect from taking Bifidobacterium lactis B55?
You may begin to notice improvements in gut health, such as reduced gastrointestinal symptoms like bloating or discomfort, within a few weeks of consistent supplementation. Individual results can vary based on factors like diet, lifestyle, and overall health.
Is Bifidobacterium lactis B55 a cure for diseases?
No, Bifidobacterium lactis B55 is not a cure for serious diseases. It is a dietary supplement that supports overall gut health and immune function. It should be used as part of a balanced diet and healthy lifestyle, not as a replacement for medical treatment.
