Bifidobacterium lactis W52

Also known as: B. lactis W52, Probiotic strain, Bifidobacterium lactis W52

Overview

*Bifidobacterium lactis* W52 is a specific strain of the *Bifidobacterium lactis* probiotic bacterium, commonly found in fermented foods and the human gut. It is available as a dietary supplement aimed at supporting gut health and immune function. This strain is known for its ability to survive passage through the stomach and colonize the intestines, where it exerts its beneficial effects. Research on *B. lactis* W52 is considered to be at a moderate level, with several studies examining its impact on gut health and immune function. The available evidence is generally of good quality, including randomized controlled trials (RCTs) and systematic reviews. As a probiotic, it is not absorbed into the bloodstream but rather acts locally in the gut. It is generally considered safe for most individuals, but caution is advised for those with severely compromised immune systems.

Benefits

While specific studies on *B. lactis* W52 are limited, probiotics like *B. lactis* generally support gut health by enhancing the gut microbiota composition and potentially reducing symptoms of irritable bowel syndrome (IBS). Probiotics have demonstrated modest effects on gut microbiota diversity and symptoms of gastrointestinal disorders. They may also help modulate immune responses and improve symptoms of certain gastrointestinal disorders. Probiotics can lead to a small but significant reduction in body weight and BMI in healthy adults. Benefits typically manifest within weeks of consistent supplementation. It is beneficial for individuals with compromised gut health or those seeking to enhance immune function.

How it works

*B. lactis* W52 acts by colonizing the gut, enhancing the production of short-chain fatty acids (SCFAs), and modulating the immune system. It primarily interacts with the gastrointestinal and immune systems. As a probiotic, it is not absorbed into the bloodstream but rather acts locally in the gut. Probiotics generally influence gut barrier function and immune cell activity. By colonizing the gut, *B. lactis* W52 contributes to a balanced gut microbiota, which is essential for overall health.

Side effects

*B. lactis* W52 is generally considered safe for most individuals. The most common side effects are mild gastrointestinal symptoms such as bloating or gas, occurring in more than 5% of users. Uncommon side effects (1-5%) are not consistently reported. Rare side effects (less than 1%) include the potential for systemic infections in severely immunocompromised individuals. No significant drug interactions have been reported. It should be used cautiously in severely immunocompromised individuals. Pregnant women and children should consult healthcare providers before use. If adverse reactions occur, discontinue use and consult a healthcare professional.

Dosage

The minimum effective dose is typically 1-10 billion CFU (colony-forming units) per day. The optimal dosage range is 5-10 billion CFU per day for general health benefits. The maximum safe dose is not well-defined, but doses above 10 billion CFU are generally not recommended without medical supervision. It is best taken with food to enhance survival through the stomach. *B. lactis* W52 is available in capsules, tablets, or fermented foods. As it acts locally in the gut, absorption factors are not applicable. No required cofactors have been specifically identified.
