Have been with an underactive thyroid for 12 years, taking thyroxine 50 plus Nutri Adrenal and Nutri Thyroid at advice of Dr. BP. I just had a blood test TSH 1.21mU/L, haven't done T3 and T4 as this is NHS blood test. The advice I expect to hear from you now please is regarding the low folate 4.1 ug/L!! What is the best form of increasing the folate levels and what brands? I also have a recently diagnosed acid reflux that is manifested with constant cough and taking LAnsoprazole 15 mg. Since few months ago I have terrible eczema on my hand too. I had feeling that something is not right in my body. From previous experience I heard impressive knowledge and experience here and now rely on your help how to quickly regain the levels of folate to possibly help me with sleep, maybe even eczema and even cough? Many thanks!
