I was born with my thyroid non-functional, and it never will. When I was born (late 60's), it was not a blood test done on every new born as it is today. I was fortunate enough that my mother had common sense enough to realize I had some abnormal features, dry skin as an infant that was like fish scales, and a cry much like a cat, she diagnosed early enough, got me to the doctor for his diagnosis. I could have become a veg. as thyroid hormone is very important for many functions of your body.
I take Armour Thyroid- Forrest Pharm.Co. -180mg daily.
Armour is a natural thyroid made from dessicated swine (oink) glands. As sick as that sounds, it is the best that one can get, as it offers both T3 and T4 hormones which you can not get both from a synthetic, ie levothyroxine. Generic brand of this Armour is generally made from dessicated bovine (moo) glands.
