How do you know whether your gut microbiome is in good shape?
Scientists know gut microorganisms were interconnected with gut health and overall health in multiple ways. But how do you know if you have a healthy microbiome? Today, we not only know which microbes are there, but we’ve also learned a lot about what they do, and how they influence our digestion, immunity and even mental health. -
