I have been on Erfa Thyroid for about a month now, and I have to say I am not that impressed. I can feel extremely agitated and almost feverish one minute, pointing to hyper, but then feel cold and tired the next. It seems I never feel stable, but keep switching between feeling hypo and hyper. I don't think I have felt normal one single day since switching to Erfa.
Before going on Erfa, I was on Armour for a while, but gave into pressure to switch to Erfa because "everyone" is supposed to avoid Armour since the reformulation. But I have to say that I felt better on Armour, and especially more stable throughout the day. Unfortunately, I don't think that I stayed on it long enough to have time to work my way up to the optimal dose for me.
I was on 5 grains of Armour, and decided to switch to 6 grains of Erfa since it is slightly weaker and does not seem as potent.
The main problem with Armour is that I have to chew the pills up for optimal effect, and I don't really like the taste (I think the last batch I got was worse in that respect), but I guess you get used to it.
I have read so many glowing reports on Erfa, but I seem unable to make it work. I don't know why; after all, it only contains a few inactive ingredients, none of them known to interfere with thyroid hormone absorption, so I really cannot explain it...but I cannot deny it either.
Unfortunately, NP Thyroid does not seem available in Europe at this time, so I'm stuck with either Armour or Erfa (unless I go back to synthetics).
I have tried to swallow, chew and take Erfa sublingually, and I see no difference in symptoms.
I'd appreciate any input on this.
Is anyone else here on Armour and even preferring it to Erfa?
