Can I take raspberry ketone diet pills with under active thyroid?

No human studies yet. Yes, but while raspberry ketones are touted as a miracle weight loss supplement ; some animal studies suggest it might help, there have been absolutely no human studies to show if it really helps. If you're trying to lose weight i'd stick with a healthy diet, exercise ; herbs that have been proven to help in human studies-see http://bit.Ly/178bmuf re: proven supps ; http://bit.Ly/1dhw9ht re: diet.
