Bifidobacterium longum

What is Bifidobacterium longum?

Bifidobacterium longum (B. longum) is a beneficial probiotic bacterium naturally found in the human gastrointestinal tract. B. longum has gained significant attention due to its various health benefits including digestive health and increased immune system function.

Health Benefits:

Supports Digestive Health

There are various mechanisms through which B. longum is believed to benefit digestive health and comfort. B. longum can help to maintain a balanced gut microbiome by supporting healthy gut flora while limiting the growth of harmful pathogens. This bacteria is believed to inhibit pathogen overgrowth through lowering the gut pH by producing short-chain fatty acids such as acetate and lactate. Studies also indicate that B. longum can strengthen the gut barrier, and alleviate symptoms of conditions like Irritable Bowel Syndrome.

Boosts Immune Function

B. longum may boost immune system function through its potential immunomodulatory effects, therefore helping to protect the body from infections and supporting long term health. One study found that treatment with the BB536 subspecies of B. longum enhanced the innate and adaptive immune responses in elderly individuals with a lower grade of immunity.

Supports Metabolic Health

B. longum shows great potential for supporting metabolic health. For instance, research found that supplementation with the APC1472 strain of B. longum was associated with decreased body weight and increased glucose tolerance in obese mice, as well as a positive effect on fasting blood glucose levels for overweight humans.

Typical Use:

B. longum is commonly used in probiotic supplements aimed at contributing to a healthy digestive system and enhanced immunity, either as a single strain or within multi-strain formulations.
