I have been battling hypothyroidism for years. It got worse after having my children and suddenly put on 20 lbs with no logical explanation. I had been seeing an Endocrinologist for almost a year and not feeling any better. I found this book after seeing a Functional medicine practitioner and decided to give it a go. IT WORKS!!!! I FEEL BETTER. My brain fog is gone, my achiness, bloating, irritability, fatigue … GONE. I feel the way I expected to feel after starting Synthroid. I’ve also lost 12 lbs in a month and the scale keeps going down! Yes yes yes!!! I’m so thankful and relieved. If you have thyroid trouble - GET THIS BOOK!
