what dosages of vitamins and minerals should i be taking for hypothyroidism. i am lucky to have been given a diagnosis but because i have become so low with excrutiating symptoms and feelings of being suicidal my doctor has agreed to try and have my t3s tested although she says the labs in the uk only do them for an endocrinologist. (is this the case ). its just i want to ask her to try me on armour instead of levothyroxine. i am on folic acid but i have read that its better to have normal levels for b12s for example and i want to take whatever i have to before the blood results come back to give the armour (if i get it) the best chance of success. would be grateful for any information .
