Bifidobacterium is a genus of gram-positive bacteria that naturally inhabit the human gut. These bacteria are considered beneficial for their ability to ferment dietary fibers and produce short-chain fatty acids, which can have numerous health benefits. Some of the most commonly studied Bifidobacterium strains include:
- Bifidobacterium bifidum
- Bifidobacterium breve
- Bifidobacterium lactis
- Bifidobacterium longum
- Bifidobacterium longum. Sub infantis
- Bifidobacterium animalis
Here are some potential benefits of Bifidobacterium:
- Improved digestive health: Bifidobacterium can help improve gut motility, reduce inflammation, and prevent gastrointestinal infections (1, 2).
- Enhanced immune function: Some strains of Bifidobacterium can help regulate the immune system by increasing the production of certain antibodies and reducing inflammation (3, 4).
- Reduced risk of allergies: Bifidobacterium supplementation during pregnancy and early infancy has been associated with a reduced risk of eczema and other allergic conditions (5, 6).
- Improved mental health: Some studies have found that certain strains of Bifidobacterium can improve mood and reduce symptoms of anxiety and depression (7, 8).
- Lowered risk of chronic disease: Bifidobacterium may help reduce the risk of chronic diseases such as cardiovascular disease, type 2 diabetes, and colorectal cancer (9, 10).
