Discussions that mention synthroid

Thyroid Disorders board

The potency of Armour has, over the last 10 years, been far superior to Synthroid and at least as stable as the other synthetic thyroid meds.

Anyone who is perpetrating information that Armour is unstable and inconsistent is lying or has not been paying attention to the facts for the last several years. In the past, before it was possible to measure the thyroid hormone content of Armour, thye measured its potency by guaging the amount of Iodine in it, and it wasn't nearly as consistent as today's formulation.

It is that older information that is still perpetrated by many medical schools and by the drug reps peddling Synthroid and other synthetics. Since these are the sources of information that many doctors rely on, obviosly they will believe that Armour is inconsistent and inferior. We know better than to believe that :)hogwash :), though.
My question to you is why would your doc put you on Synthroid AND Armour? Wouldn't that possibly cause you an overdose of T4? But for your question on Armour, I've read/heard the instability rumors to. But I don't buy it. I feel quite stable on the Armour after being on it 14 months. If it was really that unstable I think I would "feel" the fluctuations. By the time I was diagnosed with hypo I had almost every symptom ever attributed to hypo. I'm feeling much better than before after being on Armour. Another dr after hearing I was on Armour, and she thinking it isn't any good, suggested I take the synthetics. My response is "no way would I switch from taking Armour".

I think the original poster menat that she WAS taking Synthroid but is now taking Armour. However, I DO take Unithroid and Armour, so I'll answer your question. The reason is this:

The human thyroid gland makes approximately 90% T4 and 10% T3 (A ratio of 9:1). Armour has approximately 76% T4 and 24% T3 (a ratio of 4.22:1).

Many people who take Armour have a problem in that to get enough T3, they don't get enough T4, or to get enough T4, they get too much T3.

The plan is to supplement the Armour with enough T4 (Synthroid, Unithroid, Levoxyl, etc) that the ratio of the thyroid meds you are taking is about 9:1, just like what a healthy thyroid gland would produce.

To do this, it means carefully monitoring Free T3 and Free T4 levels and calculating dose changes is a bit more complicated than most doctors like to mess with, but speaking from experience, I am doing MUCH better on this regimin than I was on Armour alone.
