Which thyroid medication has the best absorbancy with the least side effects?

More complicated. Don't know how one can tell which thyroxine tablets are best absorbed in a one individual, because of the complicating factors. If having trouble, one can save up some money and buy the name brand every time. Then, eat similar amounts and similar types of food near the time when thyroxine is taken, plus take it at the same time every day. Calcium, iron, antacids, etc., changes the absorption.
