My doctor recommended Thyroid Synergy for me by Designs for Health as I'm experiencing low T3, but not so low that it's technically out of lab range. I read the only review I could find, and it supposedly really helped this one lady, so I'm giving it a try. I've only been taking it for a week though, so I have no idea if it's actually going to work for me or not.
If it were me, I probably wouldn't do a weight loss shake. It's not going to fill you up the way good Primal foods will. As far as the supplement, I guess really the only way to know is to try it. Are there any reviews out on it that you could find?
