I have meanwhile tried NatureThroid-similar to Armour except bovine. Armour was not available and it seems had been reformulated as well and many people were not happy with this formula.
After 3 weeks, I stopped the trial, having gone from 2 half grains down to only one half, as I was having adverse effects, like palpitations, nausea, chest pain. No less tired, I had to crash every afternoon.
Now I am back to acupuncture, high dosage vit B, lots of seaweed and tyrosine twice daily. Maca, Tulsi, Ginseng etc. I feel somewhat better.
Am getting adrenals and ferritin tested as I am probably not converting T4 to T3. If the nutrition etc isn't enough, I'll look for just T3.
