The leader in Microbiome Medicine offers a revelatory guide to the gut-thyroid connection, with cutting-edge information—and a surprising source of thyroid illness 

If you are one of the 20 million Americans living with thyroid disease or one of the thousands living undiagnosed, Dr. Raphael Kellman understands your suffering. Between inaccurate diagnosis, a wide spectrum of symptoms, and doctors who may not be familiar with the intricacies of thyroid dysfunction, it’s hard to get the treatment you need. While general hypothyroidism and Hashimoto’s thyroiditis are the most commonly known thyroid issues, there is an underdiagnosed and yet incredibly prevalent condition: Non-thyroidal Illness Syndrome (NTIS). It can cause unexplained fatigue, memory issues, problems with focus and decision making, and even dementia, and affects as many as 20% of Hashimoto’s sufferers.  

Luckily, Dr. Kellman has a clinically proven, expert protocol that has given thousands of patients a path to health—and now he’s delivering it to you. You’ll discover: 
  • How your thyroid function affects your overall health—and how its dysfunction can explain your troubling symptoms 
  • The 4P Protocol for healing the microbiome 
  • How everyday household products, cosmetics, plastics, and medicines can disrupt your hormonal systems—and how to detox
  • A 30-Day Thyroid Rescue program, including meal plans and lifestyle changes 
Microbiome Thyroid helps you take control of your environment, your diet, and your life, guiding you toward the right diagnosis, the right treatment, and overall hormone balance.
