"I have been so happy with the thyroid formula. I tried it at the suggestion of my doctor and my sister as thyroid problems post-pregnancy seem to run in my family. I have tried everything to loose weight, diet, exercise, but I was fighting off constant exhaustion. After a couple weeks of taking these, my energy levels rose and I started to loose weight and my appetite seemed to be under control. After four months, I have lost a considerable amount of weight and have more energy. I am even able to sleep better!"
