In this episode, Tara sits down with Dr. Oscar Coetzee of Designs for Health to explore how gut health, genetics, and nutrition intersect with anxiety, depression, and overall mental wellness. They unpack keystone gut microbes, LPS and leaky gut, why whole‑food diets and polyphenols matter, and how functional labs like stool and organic acid tests can guide targeted support.
