Health Begins in the Gut: What is the Gut Microbiome? The human gut microbiome contains around 100 trillion microbes. There are only about 10 trillion human cells in the body. That means that approximately 90% of the cells in your body are actually non-human organisms living in your gut.
What happens when your gut doesn’t function properly? Problems with your gut can lead to more than just stomach aches, gas, and bloating. Your gastrointestinal system is a highly complex system involving trillions of living organisms alongside your own human cells.
