Each person has different needs when there are thyroid problems. Unfortunately the medical "industry" is instructed to believe that only a single method of measuring the need is necessary (TSH) and only a single medication should be used (levothyroxine). As all of us know this is total bunkum of the highest level and leaves many thousands of sufferers in this country alone ill for the rest of their lives if they do not learn the truth and do something about it for themselves.
You appear to be one of those people, just as I am also one of them. We have both ignored the doctors and as a result have regained some sanity and health back into our lives.
You should be made aware of the fact that the dose of NDT necessary to return you to optimum health may vary from brand to brand, so no direct and reliable comparison is possible between levo and NDT in general. I need 2x Thyroid-S but 3x Thiroyd to achieve the same result.
All the best to you and keep trying until you find the best dose for yourself according to symptoms irrespective of what any blood test may indicate your TSH to be.
