I have an under active thyroid (& fibromyalgia) was taking 125 of Levothyroxine daily - side effects - bad. Am also receiving repeat prescription of Vit.D. & B12 jab. Decided to try natural route after seeing Naturopath- feeling great...but,GP concerned as TSH has gradually climbed from 4.52 to 13.4. He suggested I contact Thyroid UK - though in favour he says local health authority will not allow him to prescibe 'Natural Desiccated Porcine Thyroid' - so I have 2 questions. What does it cost to buy it privately & is an individual allowed to? Secondly & more important to me because it involves my faith & conscience (because as last resort I could return to Levothyroxine) does N.D.P.T. contain blood components/fractions? Many thanks for qualified expert replies.
