What is Bifidobacterium?

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).
