Thank you for all the research you do and the knowledge you impart to us, your customers! I had thyroid cancer surgery when I was 37 which was in 1986. My prognosis, obviously, was excellent, however, after a lifetime of thyroid difficulties I never really felt like I could tackle everything I wanted to do, and my lists have always been long! I’ve been using Function salve and the roller ball for a few weeks now and realized after a few days of use I had more energy and stamina. I will always be on thyroid replacement meds but now with Function, I have a much more optimistic outlook in addition to more energy.
