I put this batch number into a search here, but nothing very recent came up. I have been taking Thyroid-S successfully for a number of years, 1.5 grains in the morning. My Free T4 is in the lower half of the range, around 14.9 (12-22) and FT3 around 5.5 (31.-6.8). I started this new batch on 28th December. Felt OK with it initially and did a Thyroid Panel blood test on 19th January. I was surprised to see my FT3 had gone up to 8.1 and FreeT4 was at 18.1. My TSH had gone up slightly to 0.009 (.27-4.2).I dropped the dose to 1.25 grains daily and within a few days began to feel very hypo, the first symptom for me being extreme 'air hunger'. So today, I took 1.5 grains this morning and now feel very hyper again.
I do have other health issues going on at the moment. But I wanted to ask if anyone else is having problems with this particular batch and if so, what are they and how are you dealing with it.
Thanks for looking.

Yes, this one is the most recent healthunlocked.com/thyroidu.... I have a similar experience symptom wise on a 2022 batch, but my FT3 and 4 stay low. And I never felt OK on it. It is odd you did feel OK at first and now feel hyper on the exact same dose. I had to drop my dose from 3.25 to 2.25 grain.
I hope if enough people report this back to the manufacturer, they will go back to their previous formula, which I believe they have changed.
I am surprised there aren't more people reporting problems with it. It's such a pain having to mess about with doses. I might split the dose into 2 over the day and see if that helps. Thanks for your input anyway, very helpful.
I reported the new Thyroid s 22 batch back 18 months ago. Lots of people were having trouble with the new batches too. The pills had changed and became harder and greenish.
I have no thyroid and no gut, hashis or any other things going on and I had been very well on it for over seven years. I did always split my dose 1.25 am and 1 pm. The batches do vary for years I was on 2.5 but had to drop down to 2.25.
Thanks. I have stopped taking it now and am T3 only. Starting to feel better . I don't think the change in formula is the only thing going on with me - just a bad coincidence that the two things happened at the same time.
A summary of known and suspected potency of Thyroid S batches.
Experiencing symptoms of overstimulation of thyroid hormones. Recent blood tests 19th January 2024, show over range FT3. Started this batch 28th December 2023. The symptoms didn't start straight away but took some time to emerge. Reducing the dose by a quarter grain has hypo symptoms, so it is becoming difficult to establish a stable dose.
I have tried the manufacturer but never receive a reply. I have now given up after purchasing at least 2000 plus grains. Thank you for all your reporting. I still have people asking for advice on buying them but I will not because they simply don't work anymore.
For over 5 years I didn't think and just took my dose of Thyroid S -
never looked at batch numbers and just got on with my life - grateful I had jumped ship, purchased this NDT - and found a level of wellness the NHS refused me.
I too have experienced 2 batches this past year which I couldn't use - 1 x 21 and 1 x 22 production - I contacted my supplier who is English but ' on the ground ' in Thailand.
Apparently there is a similar system in Thailand to our Yellow Card but told that as far as he was aware there were no issues with any batches of Thyroid S -
In all honesty I wasn't expecting him to say anything much anyway - as what would have been the next step ?
I'm now on another 22 batch that suits me very well :
I don't have a thyroid - post RAI thyroid ablation 2005 - so totally reliant on thyroid hormone replacement - and my dose not large - so tend to run behind the curve as to feedback on batches.
It's all so hit and miss isn't it, when we should be given proper treatment and support from the NHS (In my dreams, I know!). My thyroid has been destroyed by antibodies and heavy metals over the years, so I am in a similar position to you and I take a small dose. I couldn't take either Levo or T3 so have to rely on NDT.I have written to my UK supplier (probably the same one as yours) asking if I bought some more, could they guarantee not to send me this batch. They are not going to say there are issues are they, as that sort of admits liability. The American alternative is exorbitant in cost now.
Good luck with that! I hope you get some joy with Sriprisit, everything, I've tried, they've either ignored me or said that no one else has reported any issues. I am having symptoms with the 23T01003 batch. The manufacturer really needs to change it's formulation, and put less fillers in it too.
I did purchase and start this batch too. In fact I bought 1000 grains, but like all the others since the change in 2022 it doesn't work for me anymore.
They are not going to change the Thyroid s back to how it was so personally I am giving it up.
Before they changed the NDT I took it for over 7 years without a singe problem.
Very interesting. I have some American NDT within date, which I never took because the Thyroid-S was fine. I will have to see how that goes. So what are you going to take instead?
Has the manufacturer confirmed they reformulated it? I am asking because I find it to work less consistently now, but I have not seen any confirmation from Sriprasit that they actually changed the formula. If they did, I am giving up on it.
Sriprasit have specifically told me that they haven't changed formula. However I think they had to change the raw thyroid supplier when there was swine fever, and also the coating is harder on the tablets I believe, but I don't have any confirmation of this. Because of that, and the problems when Armour altered formula in 2009 making it less easy for some to absorb, I now chew the Thyroid-S thus by-passing the hard coating effect.
I can only think that's mainly why I haven't had any problems with Thyroid-S, and also the fact that I didn't have any manufactured in 2022 when the problems seem to have started! I know that some people who had a problem with the newly reformulated Armour in 2009 were able to get on with it again when they chewed it, making it more easily digestible, and some even took it with honey to overcome the problem of more cellulose and less dextrose than before.
Yes I'm sure it has, I feel fine at the moment and I didn't feel fine for years on 2.5 and 2.75 grains, but I've always chewed Thyroid-S so I can't really compare with how I'd be if I swallowed them. Also my latest blood tests show a difference, in line with the percentages of my current batch, so I must be absorbing it somehow.
No I've never split the dose. I started with Armour then ERFA, neither of which had such hard coatings as Thyroid-S now has, and my first specialist said it was easier to take the dose in one go.
What were the problems with Armour that they solved with chewing? I wonder if I could solve mine that way (not able to take the dose I need without hyper like symptoms). Started chewing yesterday, just to be sure.
Armour's manufacturers eventually admitted that they had reduced the dextrose content, and increased the cellulose content, making it difficult for some people to absorb it properly. Various people suggested chewing it and also taking it with some honey, which seemed to work for a lot of people. I didn't try that though, I switched to ERFA at that time, but ever since I've chewed whatever I take just in case gut issues or something like that, might prevent proper absorption.
Please let us know how you get on by chewing Thyroid-S! I'm not sure if it would prevent hyper symptoms though, the whole situation is dismal and so wrong for us all!
The chewing has improved hypo symptoms. Thanks for that tip! I take it with honey or agave syrup. Still at the same dose, haven't retested. I'm staying at this batch (22054) for now, though not symptom free.
I'm so glad that chewing has helped. It's also very interesting that taking honey or agave syrup helps, I've never done that but remember that that's what was recommended when Armour reformulated in 2009. It could be that the manufacturer has altered the ratio of dextrose/cellulose, and according to the supposed list of ingredients in STTM they include two different types of cellulose. I guessed that Armour had done so to reduce costs, in which case others might well do the same. I'm still taking 23T01002 but have reduced the dose by 1/4 of a grain to 3 grains a day and feel fine, but really worry about the future!
That must be it, then. Jacking the price up and still reducing manufacturing cost. And of course they won't admit to reformulation in that case, nor go back to the old formula. 😔
Why would they not go back to the old formula, if they get enough complaints and less sales? Serious question, other brands haven't done it either and I really wonder why change a good thing.
Try to find out % amounts on t4 and t3 . Compare it to previous batch. Gives you an idea which way to proceed? Ask Helvella or Framboise about %. They may be able to help you,
I haven't seen any comments about this batch anywhere else apart from the one other comment here, someone who normally took ERFA tried that batch of Thyroid-S and thought it very weak. I'm taking 23T01002, having previously taken batches manufactured in 2021 and before, and I'm doing well on it. My recent blood test results show slightly higher FT4 (+0.9 pmol/L) and FT3 (+0.7 pmol/L) than previous batches I've taken, so I've reduced my dose every other day - 3 grns one day and 3.25 the next. I have four jars of your batch so will start that to see what I think of it. I take the full dose in the morning and chew it rather than swallowing it.
The percentages for the batches this year are:
23T01001 T4 104.9% and T3 98.3%
23T01002 T4 108.3% and T3 102.9%
23T01003 T4 103.1% and T3 102.5%
23T01004 T4 103.9% and T3 102.0%
My previous batches have had a higher, or even, percentage of T3 than T4, so the fact that my FT4 has increased more than FT3 on batch 23T01002 fits with those percentages.
The Thyroid s worked well for years but sometimes the potency differed slightly. For years I always took 2.5 grains per day then back in 2018 I had to reduce to 2.25 to achieve the same results.
The main difference happened back after covid with batches from TA22 something. I had just finished my batch from TA21 and started up on TA22 the batch after Covid. After only 44 days I started to fall down. I had a blood test and these were the results.
From TA21 year. FT4 19.70 FT3 6.06
From TA22 year FT4 12.90 FT3 2.76 These grains had changed and never contained the same as before covid.
I hope this makes sense. I have no thyroid or gut problems so starting from an even playing field so to speak.
Yes - I know and I too had a couple of different batches from both 21 and 22 that did not work for me - however I'm now on another 22 batch which has restored my health and well being - I am post RAI thyroid ablation for Graves 2005 - so presume I'm without any thyroid production - and anxious going forward.
True I could go back to the NHS for at least the T4 - but then face being dosed and monitored on a TSH which leaves me under medicated anyway -
So at 77 my bucket list is likely self sourcing T3 and T4 and starting again - which I really do not want to have to do.
Yes we are very similar, lacking in a thyroid and 77 years old too.
I do get Levo plus T3 here, free. I live in France the T3 is made here anyway. T3 never works for me it's too fast acting. Back to the Thyroid s for me I think.
How many grains do you take and do you chew yours first. I am asking because I am doing something wrong now with these new ones. Thank you. I was taking 1.25 am and another 1 pm for years but I will have to change now.
My bucket list is being able to go round the supermarket once a week without falling over, great.
I seem to only need 1+1/2 grains which I take down with water just once a day at around 2/3 in the night at a toilet break -
I also take adrenal glandular and need to maintain my core strength vitamins and minerals - ferritin, folate, B12 and vitamin D - at optimal -
as I read that having Graves and having had RAI thyroid ablation ( 2005 ) this toxic substance is taken up by other glands and organs in the body - and believe I have experienced same as been more unwell post this RAI treatment.
I wouldn't say I'm 100% and as well as I felt throughout my first couple of years on Thyroid S but I have back my independence, can mow my own lawns and able to drive again and have back my life.
Thank you it's very interesting. I too only ever required 2.25 which is a small amount for some others. I never had Graves I never experienced the same as you.
It's weird because I was adopted and my adopted my family had two cases of Graves.
I however. came from a family in which many had Thyroid problems but not Hashi's or gut problems. Everyone starting with having their Thyroids removed in their sixties.
It was good of you to reply so quickly, I too would just like to be able to walk my dogs again and do some gardening, which I love.
Yes I think that's exactly what it means, 3.9% higher than baseline 38. I know there are tolerance levels up and down for levo as well, in fact most drugs, which are acceptable, I can't remember what they are though. But I'm sure that Sriprasit would keep within the accepted levels because they are a major manufacturer of medicines in Thailand, and wouldn't want to risk any problems for their business as a whole. Quite how they get any differences between batches, when they use a set formula, beats me though!
Yes it is a bit of a puzzle - maybe different fillers were introduced when they were apparently ' reformulating Thyroid S ' - but something has definitely changed :
I wish they'd tell us more about it! If the coating has changed that must be an additive, if the smell has changed that must be something removed etc...
It was cancelled because of my low FT3 results. That was last June and I am still trying to improve it without success.
When you have scan or MRI here you received a copy which is useful. I did send a copy to a top ear surgeon in the UK and he has told me that it's very slow growing and not to worry.
In the meantime I am trying the Thyroid s, starting today.
As a matter of interest but off-topic, how do they send you copies of the MRIs? I've just asked for copies of some scans I had in a private hospital here and they send them by a very weird portal which needs a download that my Mac refuses. When I asked how else they could send them they just looked blank.
What I have seen is the MRI distributed on a CD - and the CD incorporated a viewer. At the time, I know it worked on Windows but don't know if there was a Mac version in there as well.
I found quite a good video on how to view MRIs, X-rays, etc.
Note: Do read the comments/replies regarding whether software viewers are "free" or not and alternatives.
I suspect that what the download is doing is offering a Windows viewer which macOS will not be able to use - but it might be a zip. But it should be possible to download the images or extract them from a zip.
Sorry - I don't have any source of MRIs to try this out!
Thank you, I'll check these. In the past I've been given CDs but they said they no longer do that. This time they told me to download a program called Weasis for Mac, but neither of our Macs liked it, and my husband's is up to date so should have worked, so I was a bit fed up. This may do the trick though, thanks again!
helvella thank you so much! I'm sorry I didn't reply sooner, I had seen your post but we have decorators here and today is the first day I've been able to get back into my study and set things up again. I've just told my husband that you were able to download the Apple Silicon version of Weasis and he's giving it a go now. I'm still on Sierra and can't download anything until I update it all. I probably won't look at my scans but I like to have copies in case they're ever needed in the future. Thank you again
