Why your gut loves polyphenols

Polyphenols are considered prebiotics because they help shape the environment in the gut microbiome. By doing so, they benefit the good bacteria, like Akkermansia muciniphila, and promote a healthy gut.

It’s not always easy to get polyphenols simply through a healthy diet. These twice daily capsules are a convenient way to boost polyphenol intake.
