Bifidobacterium Longum is normally found in the colon, mouth and vagina.
Research links this bacteria with improving the delivery system for liver cancer gene therapy†, has anti-anxiolytic effects which decreases the excitability of gut neurons†, and has been shown to help in the treatment of Coxsackie induced inflammation in the heart†. This bacteria has also been shown to create anti-tumor enzymes†.
