text: I have been using this product for about six months. My thyroid seems to be both overactive and underactive at times. I have tried many different supplements in hopes of staying off the prescription medications, and this one is working the best for me. I think it took about 30 days for me to see results, but I have felt pretty much stable. I sleep through the night, have consistent energy and my mood has improved. I would highly recommend this product to anyone with thyroid issues.
