There are trillions of microorganisms (bacteria, viruses, fungi and more) inhabiting the human body. You can find these microscopic critters on your skin and in places such as your nose, throat and genitals. However, the largest collection of bacteria resides in your intestinal tract forming the gut microbiome.

Within the intestinal tract itself, billions of native bacteria coexist with human cells — influencing nearly every physiological function.

Researchers are still unraveling exactly how these microorganisms impact and interact with our biological systems, it’s become evident that the colonies of microbiota living in and on the human body actively impact our health and play a significantly role in maintaining homeostasis.

More Bacteria Than Human

While scientists originally thought that the number of microbial cells outnumbered human cells 10 to one, more recently, they’ve determined the ratio is much closer to one-to-one. There are around 30 trillion human cells in the body and an average of 38 trillion microbial cells, making us only 43% human. And while they only make up about 1-3% of our total body mass, these microorganisms have a tremendous impact on our bodily functions.5
