Basic Information
Product Description
🔬
Bifidobacterium animalis subsp. lactis is a Gram-positive anaerobic rod-shaped bacterium which can be found in the large intestines of most mammals, including humans. Bifidobacterium animalis include two sub-species: Bifidobacterium animalis subsp. animalis (B.animalis) and Bifidobacterium animalis subsp. lactis (B.lactis) — previously described as two distinct species.
🛡️
Since Bifidobacterium animalis subsp. lactis is extracted from healthy human gut flora, it naturally resists acid, bile salt and synthetic digestive juice. It also strongly adheres to the intestinal tract epithelium, helps to strengthen immunity and maintains the gut flora balance.
🧫
Bifidobacterium animalis (include B.animalis and B.lactis) is the most popular used probiotic bacteria belonging to Bifidobacterium spp. They colonize the human gastrointestinal tract — representing up to 90% of the bacteria of an infant's GI tract, reducing to ~3% with age. They participate in metabolism and fermentation of glucose, galactose, and fructose to produce Lactic Acid, Acetic Acid, Enzymes, Vitamins, etc.
