Sharing for info but also a question around changes to formulation.
I’ve recently had my T3 increased which meant moving to Thybon Henning 20s. Since I’m allergic to acacia, I set about trying to find out if it contained it. I spoke to 2 pharmacies (SmartWay and Roseseway Labs) as well as doing my own online research and the verdict was it contains acacia powder.
The cost difference between the Thybon (about 50p a tablet) and the next cheapest without acacia (Teva at over £3 a tablet) was so large that I agreed with my doctor to at least try the Thybon. My previous acacia reaction was mild and I’ve generally found my allergy symptoms improving. If I didn’t react it would save a fortune!
So the tablets arrive, I glance over the leaflet included but am surprised to see no acacia listed in the ingredients. Those listed are: liothyronine hydrochloride, pregelatinized corn starch (maize), corn starch, microcrystalline cellulose, sodium carbonate, sodium thiosulfate 5H2O (Ph. Eur.), colloidal silicon dioxide, hydrogenated castor oil. Picture attached and I’ve been careful to include the company info too.
Is this likely to be a translation issue online? Or has the formulation changed recently?
Either way, I’m very pleased it’s not going to cost quite so much for now and thought it might be useful to share in case anyone else is in the same boat!

Links to product documents for many, many products are in my medicines document - see around page 478 for Thybon Henning. For UK products, I have little tables which show which products contain lactose, mannitol or acacia.
It is simply too much work to do the same worldwide, and not very helpful when official documentation is often not accessible so many boxes would be blank.
helvella - Thyroid Hormone Medicines
I have created, and try to maintain, a document containing details of all thyroid hormone medicines in the UK and, in less detail, many others around the world.
Thybon Henning also has neither lactose nor mannitol.
The least expensive UK liothyronine, based on company list prices/what the NHS pay, is currently Roma capsules in 5, 10 or 20 microgram dosages. (£55, £65 and £55 respectively - for 28). Pharmacies will charge more for private prescription dispensing. That too is free of lactose, mannitol and acacia. Yes, more than the Thybon Henning.
This is blowing my mind. One of the pharmacists I spoke to mentioned that he was doing what I was doing - googling to find the answer. At this point I assume we both found the same, incorrect source!
And thank you for the links to your documents. I had been using the uk ingredients matrix to search for alternatives as it happens! Very much appreciate that can’t be replicated for all of them. It’s a behemoth! And to be honest I think I’d hit my brains foggy limitations when it got to the more detailed information. Can’t believe I was so close and managed to miss it by a mile! It’s wild to me though that the pharmacy didn’t have better information. My cynicism grows again!
Thanks Hedgeree! I had in fact been using it to compare uk brands but hit my limit in deciphering the wider document. Very annoyed with myself that I was within inches of finding the right answer. Clearly not yet on enough T3 😂
