My first thyroid medication was Synthroid which was horrible. Then I tried Armour thyroid which was much better. But it is made from pork and I believe (Acts 15 and elsewhere) that the Mosaic food laws are still in effect, so I wanted something else. Researching I found Thyrogold online. It worked better than Armour. Sometimes you have to experiment on the dosage. As for cost, overall, over a year's period, even with insurance Thyrogold is less expensive than Armour. Of course it has no pork.
