Hi - I have heard about NDT which i believe you have to buy yourself as it's unlikely my GP will prescribe it. There have been many posts by people saying that it made them feel so much better - the brain fog lifted, they lost weight and felt energised. Can anyone tell me - should i take it (I'm on 125mg levo a day). What are the benefits, should it replace levo? Should i tell my doctors? Should i take anything else with it? Can it do you any harm if you take it and you shouldn't really take it? I have so many questions to ask about it!! I have been on levo for years now and on this dose for a while and as with most people i do wonder if it helps at all? I am also taking iodine which i've heard will benefit me? A good medical practitioner please!!
