I have so many friends that feel sick just on Synthroid. I have some friends that have switched from Synthroid to Armour and were doing fine, but now feel horrible. They feel bad because the makers of Armour…Forest Pharmaceuticals reformulated the mdeicine with no warning. Now they have a ton of complaints that the medicine is no longer working. They also claim that a main ingredient of the medicine is on backorder. What is the truth here? These people have now switched from Armour to Naturethroid. They started feeling better but now Naturethroid is on backorder! A consiracy? Who knows. People please write these companies and tell them of your complaints. They need to hear us. They have bought our doctors. Please speak up.
