I've honestly never taken any beneficial thyroid products before, so i don't have anything to compare it too. I've gone from 210 --> 204.8 lbs in 4 days, but i'm assuming thats water weight due to the decrease in sodium. It doesn't give me anxiety like some reviews have noted, and i feel like i have clean energy. Appetite is certainly suppressed, and yet to have any cravings of Candy, which is my biggest downfall. Too clarify, i enjoy the product so far, i only have one bottle so if you have any recommendations on another product then please share.
