Let's Get Oral

Some bacteria in your mouth perform a surprisingly important job: helping your body turn dietary nitrate into nitric oxide.

In this episode, we talk with the MyFitStrip co-founders, Shawn Green and Juliana Kumar, about the science behind nitric oxide pathways, the behaviors that may support or disrupt it, and how understanding nitric oxide production could provide a new perspective on oral-systemic health.
