There is a fundamental connection between your brain, gut, thyroid and microbiome. If any one part of this system is malfunctioning, it will impact the others. Taking care of your microbiome is the basis of Dr. Kellman's revolutionary Microbiome Protocol, which has been proven to significantly alleviate depression, anxiety, gastrointestinal concerns, insomnia and other health issues. Based on Dr. Kellman's decades of experience as a physician and his ongoing study of the latest science, the book offers a lively, accessible explanation of how the brain works and why, for optimal brain health, you need to heal the microbiome, the gut, and the thyroid. With a proprietary three-week plan (21 days of meal plans, featuring 50 delicious and simple recipes; a complete exercise program; and a program of daily meditations and affirmations). The Microbiome Breakthrough program offers drug-free relief to anyone suffering depression, anxiety, and other mood disorders, as well as those who just want to feel better.
