★★★★★"So glad I found this podcast. Dr. Kumar doesn't want you to just mask symptoms, he wants you to understand root causes and help you truly heal. He is the best of both worlds - he shares a wealth of modern medical knowledge, but also empowers the listeners to take personal responsibility for their health."
