Hi there, I've just come across this resource so this is my first post. It's helpful to read some of these posts. Has anyone used Thiroyd by Greater Pharma Manufacturing co?
I was diagnosed with underactive thyroid in 2011, but realise I must have had it for years beforehand. I didn't start taking thyroxine until 2014.
I read Barry Durrant peatfield's book which pointed me to taking natural thyroxine rather than levothyroxine and I sourced ERFA 30mg on which I felt much better, and levels stabilised, albeit at the lowest end of the range. I can no longer get ERFA and a natural health practitioner suggested 'THIROYD'. I'm not sure it works as the last 2 blood test results are outside the low range, even though I've had to up the dose to 75mg. ERFA tasted like pig thyroid whereas this just tastes a bit sweet so it's made me suspicious.
I really prefer to keep to natural desicated thyroid and I'm not sure what to do. I also have osteopenia and am being referred to rheumatology. I think the underactive thyroid may be the underlying cause of the other issues so I really want to try and get it stabilised within the normal range.
Thanks, I look forward to hearing any suggestions, Louise

Thiroyd by Greater Pharma is taken by quite a few members, I believe.

Quite a few members take Thiroyd. It has the same amount of T4 and T3 as Erfa but the different fillers may affect how you absorb it and that may be why you need a higher dose.
If you post your recent thyroid results and ranges members will advise how much to increase dose.
You really need to know your T3 level to know whether you are optimally dosed when taking NDT. Most people taking NDT are optimally dosed when FT3 is in the upper third of range.
There are different opinions on the potency of T3, but I work on the assumption that T3 is 3 times as potent as T4, so you are taking the equivalent of 8.31 x 3 = 25mcg T4 (approx).
Add that to the 35mcg T4 already in the Thiroyd and you have each tablet of Thiroyd is equivalent to 60mcg T4.
In other words, each 60mg tablet of Thiroyd is equivalent to 60mcg T4 (Levothyroxine).
You are taking the equivalent of 75mcg Levothyroxine, and that is a tiny dose. Few hypothyroid people would feel "back to normal" or healthy on 75mcg Levo or its equivalent in NDT.
Since your blood test results are below the bottom of the range you really need to bump up your dose of Thiroyd.
You could increase by 1/4 tablet at a time if you wanted (i.e. the equivalent of 15mcg Levo), but since your results are below range I would suggest you do a first increase of 1/2 a tablet, then re-test in a few weeks. If your results are still below range then I would suggest increasing by another 1/2 tablet. After that do your increases in amounts of 1/4 tablet.
For info on how to increase dose with NDT, see these links :
You'll notice that the second link is more cautious than the first link. The third link isn't describing adjusting doses with NDT, it is really about Levothyroxine - but the principle is the same.
If you don't get a response from your tablets with the first increase of 1/2 tablet (either in how you feel or in your blood tests) I would begin to suspect the tablets are not good ones. They may have been improperly stored, or may have got damp, or they may be fakes. But it is not common to come across fakes - the tablets are so cheap it isn't worth it to the forgers to fake them.
You could try a different Thai NDT e.g. Thyroid-S or TR Man. But I would definitely suggest you find a different supplier if the Thiroyd tablets you have turn out to be useless.
