Not sure which of the 3 named would be the best route in your circumstance (or any really, i guess you kinda have to sample them and see what you like) but as far as your thyroid issue... what kind of thyroid issue is it specifically? Hypothyroidism or what? I'm asking because I might be able to send you more detailed info on what you should/should not be eating, and other things of that nature to help you NATURALLY.
Just because I can't see my feet does NOT mean I'm fat.
<- what works for me!
