Bifidobacterium Lactis

Bifidobacterium lactis, an extremely versatile and efficient bacteria in the human gastrointestinal (GI) tract, can be found in fermented dairy products and vegetables as well as probiotic supplements.

In studies, B. lactis has been shown to reduce and maintain healthy levels of cholesterol, ease ulcerative colitis discomfort, and fight Celiac disease symptoms. In combination with other probiotic strains as well as prebiotics, B. lactis could prove helpful in the support of regular bowel movements, overall GI tract health, and metabolism.

B. lactis is essential to the digestion of sugars, fibers, and macronutrients and has been shown to help reduce antibiotic-associated diarrhea risks. In addition, recent studies indicate B. lactis may also be beneficial when fighting respiratory and other infections.
