Do you need to take dessicated thyroid forever like you have to take synthroid forever? I'm thinking of buying some as I really don't want to start levothyroxine. I'm not sure that I actually will need medication long term as my thyroid has been fluctuating a lot but I don't have any autoimmune disorders. I just want a bit of a boost justnow that I'll be able to stop when I feel better again. The one I'm thinking of buying is more like a vitamin as opposed to a medication,it's called natural sources raw thyroid-does anyone ever tried these before?
