B.bifidum helps the gastrointestinal tract function better since it is part of the microflora. This reduces the chances of acute diarrhea and even helps fight E.coli infections.[1] Long and short chains of simple sugars that can be found in the GI tract are broken down and absorbed by B.bifidum.[2] Increasing the amount of B.bifidum in the body will also increase the immunity function such as lowering the severity of symptoms and decreasing the days infected with the common cold.[3] Since B.bifidum can be found in the vagina, the bacteria can fight Candida and other yeast overgrowths if present.[1]
