I've been on various and varying levels of thyroid medications for over 10 years and have never really felt good, I was shocked at how good I felt within 2 days of taking this product. I have energy without being hyper or jittery and, while I have not weighed mself, my clothes are getting looser. Fucoxanthin has been a godsend for me. As for iherb - great website, fast shipping and wide variety of products make it my new fave for all my family's needs.
