This is a tag line for a probiotic advertising.

Here is some context:

There is a world that few people know about, but given its proximity and importance, it deserves our attention. It is called the “Micro biome” and it’s located inside all of us. Our micro biomes are the communities of tiny “micro flora” or “friendly bacteria” that live inside our bodies, mostly inside our gut. Scientists estimate that there are over 100 trillion micro bacteria inside our GI (gastrointestinal) system at any given time. These tiny microorganisms, primarily found in your stomach and intestines, can have a large effect on your health and vitality.

I appreciate your help!!!
