Whether you’re sick or not, having proper immune support and health is imperative to putting you in a better place to handle stress, sickness, or anything that life throws your way. There is a lot going on in the world right now, and while we certainly don’t have the answers or a cure for Coronavirus, we do have science based studies that show there are ways to help reduce cortisol levels and stimulate your immune system. In this episode we take a deep dive into all things immune-related and share our best research-backed tips to help you stay healthy and feel your best!
