Your microbiome is all of the bacteria and other microbes that live on and in your body. Many of these microbes are beneficial, helping you digest food, make vitamins and hormones, and fight infection. But scientists are just beginning to understand the important role your microbiome plays in your overall health.
The human microbiome has been estimated to contain tens of trillions of microbial cells, outnumbering human cells by 10 to 1. And while each person’s microbiome is unique, it’s thought to be influenced by factors such as diet, lifestyle, age, geographic location and ancestry.

- Producing nutrients like vitamin B12 and K
