I bought this for my daughter. She has DS and thyroid issues. She needed meds in the past, but I took her off myself because her heart was beating out of her chest. She had to go to the nurse several times in school, so it was pretty bad. The doctors said she was on the right dose regardless. I wasn't excepting that answer and kept her off for 2 yrs. I decided to try this based on reviews, and we went to an endocrinologist to have her levels checked after taking this for awhile. I told the doctor about this supplement and she told me she would check her levels etc and see where she is at. Her levels were great and she did not need meds :) they were really low in the past. Not anymore!!

Thanks for your feedback!

love it!

My naturopath recommended this product to me. I was having trouble losing weight even though my diet was good and I walk about 6 miles a day 4 days a week at my job. After taking this for about 4 week I began losing weight.

Thanks for your feedback!

I have been suffering extreme fatigue, along with other symptoms indicative of hypothyroidism. However, all my tests came back normal and my doctor couldn't really explain why I feel fatigued all the time. My doctor's "Just rest when you're tired" advice is not really helpful if you have to go to work everyday. I used to take another product made by another company, and that worked very well until they changed the formula to make it a weight loss product. I thought it would be okay and continued taking it because all the original ingredients were still listed, except they added a few extra ingredients. Unfortunately, I started feeling fatigued again--that extreme feeling of tiredness even when I'm just sitting down and not doing anything physical. While I don't really like all the ingredients in this product, I have to admit that it does work for me. As with the other product, I didn't even notice that it was working at first. There's no energy surge or any other indication that it was working. I only realized that it was working because I have gone 3 days straight without suffering from fatigue. Sure, I still get tired if I do a lot of physical activity, but that's normal. I am praying that they don't change the ingredients on this product because it's been a long time since I felt normal.

Thanks for your feedback!

so far so good!
