What is the gut microbiome?

Billions of microorganisms live in your gut, including bacteria, viruses, and fungi. Together, they form your gut microbiome.

This community helps with the digestion of food, the production of certain nutrients, and the support of your immune system.

Your gut microbiome is personal:

The composition varies from person to person and is influenced by, among other things, diet, lifestyle, medication use, and your environment.

Why would you want insight into your gut microbiome?

Research shows that differences in the gut microbiome are associated with overweight and metabolic disturbances. This does not mean that your gut microbiome alone determines your weight: diet, exercise, sleep, hormones, and genetic predisposition also play a role.

A gut microbiome analysis maps the composition of your gut microbiome. This provides additional insights to take a more targeted look at your diet and lifestyle, in conjunction with your personal situation and goals.

The gut axes

The connection between your gut, weight, and metabolism

Your intestines are constantly in contact with the rest of your body.

The gut microbiome plays a role in your metabolism: the processes by which your body processes nutrients and uses energy.

Gut bacteria, for example, help break down dietary fiber.

This produces substances involved in the communication between your intestines and other organs.

For example, your gut microbiome is connected to more than just your digestion.
