“Having grown up in a family in which my father and grandfather were both dentists, I must admit I wanted nothing to do with the subject. Unfortunately for me that meant I have spent most of my career choosing to ignore the profound connection between dental health and whole body health. The concise and informative book by Dr. Nischwitz showed me in very clear terms that this has been a mistake. Many things affect our overall health, but perhaps none are as important as the state of our teeth. I encourage everyone to read It’s All in Your Mouth and start putting Dr. Nischwitz’s ideas into action.”—Tom Cowan, MD, author of Cancer and the New Biology of Water

“There’s been a huge shift in awareness about how to achieve optimal health, but many people still miss where it all begins: the mouth. It’s All in Your Mouth cleverly combines functional and naturopathic medicine with advanced dentistry. This book is biological dentistry at its absolute best.”—Tim Gray, biohacker; founder, Health Optimisation Summit

“A fascinating exploration of the fundamental connection between the health of your mouth, overall well-being, and your ability to perform on and off the field. An essential for anyone looking to reach their performance potential!”—Dr. Marc Bubbs, ND, MSc, CISSN, CSCS, author of Peak
