What Readers And Viewers Are Saying About Dr. Izabella Wentz

“Dr Wentz has gone above and beyond in her desire to educate people on the actions to take in the case of Thyroid disease. This book is an outstanding follow up to Root Cause. Hashimoto’s Protocol gives a thorough breakdown of exactly what needs to be done to start feeling better. Each protocol comes packed with not only instruction but also loads of great insights and proven research as well. This is an excellent read for anyone battling thyroid disorders.”


“The Thyroid Secret Docuseries greatly hits home and shines a spotlight onto the life-changing and devastating side effects caused by Hashimoto’s. I’ve suffered from this illness for over 40 years, and it is the first time I felt truly understood and validated by the honest and uninhibited testimonies. I applaud Dr. Wentz’s limitless efforts, advocacy, and mission to bring awareness and hope to the lonely and isolating world of Hashi’s. The Thyroid Secret Docuseries is empowering, and it will bring about the positive changes that are so desperately needed to turn around the current autoimmune thyroiditis epidemic.”

“I’m so excited to read a new book! Your work has saved so many lives. Thank you for being you 🙌”


“I learned that I had Hashimotos 5 years ago when I was sent to an endocrinologist by my primary care physician assistant. He was the first person who tested for thyroid antibodies fatigue, alternating diarrhea and constipation, dry skin, difficulty losing weight, flatulence, and could not fall asleep. Take levothyroxine and get used to it. I got a lecture on how our bodies age. I was 60 years old and told them to find me 2 30 year olds that could keep up with my work and travel schedule. My PA left and then my next doctor left the area and I went to a new doctor who has spent extensive time researching Hashimotos because 5 women in his life have it. He prescribed the book Root Cause and told me to read it. He said there is a difference between being ignorant and stupid and right now I was ignorant. The new DR put me on bioidentical thyroid NP – I felt better in a couple days. He told me that if I followed the 90 day protocol I would feel better than I have in years. I read all three books and then ordered all the recommended supplements. I followed the 90 protocol to the letter and used the menus and recipes. The website was a great source of information. I feel better than I have for years. I can fall asleep at night. I now know what it is like to be regular . I have more energy than I have had before. In the 90 protocol I shed 23 pounds. Purchase the books Hashimoto Protocol and Hashimoto Food Pharmacology – read them and follow them. Your health is worth the work. I also sent them to my doctor. This was a well worthwhile journey. I feel better than I have in a very long time. I look forward to the future and shedding the rest of the weight I need to lose.”


“I worked through the basic protocol from your book and am symptom free for nearly a year and my antibodies are within range. Many thanks for providing guidance and closing the gap in healthcare “
