Good news! You can get good desiccated thyroid from Canada.


NOTE: when this blog post was written in 2009, it was good news to mention the Canadian brand of NDT, made by the company called Erfa. But sadly beginning in 2014, it seemed to change in a negative way, as reported by numerous patients, even if some still used it. Complaints about symptoms returning fell on deaf ears. There have also been shortages.

Unfortunately, patients who want to switch to desiccated thyroid from T4-only meds like Synthroid et al, or those already on desiccated thyroid who want to fill their next prescription, are going to find it difficult. There are widespread shortages in desiccated thyroid like Armour, Naturethroid and Westhroid. (see my posts below).

But there’s good news, and it comes in the form of “Thyroid” by Erfa.

Erfa’s “Thyroid” is an excellent natural desiccated thyroid product according to the experience of patients who use it. It contains:

  • Dried Thyroid
  • Mag­ne­sium Stearate
  • Corns­tarch
  • Talc
  • Sugar

**Note the “sugar”. Patients also report they are able to do this brand of medication sublingually! That is good news.

The Erfa website states you can obtain their desiccated thyroid medication outside of Canada via a special access program and follow their steps:

For patients outside Canada and the US:

1. Get a prescription from your local doctor (mention hypothyroidism on it).
2. Your doctor should fill in this simple document (not required for the UK)
3. Fax or e-mail us the documents at 1-514-931-7330 or

For patients in the US:

1. get a valid prescription of Thyroid from your local doctor
2. your doctor has to fill FDA form 1572 (e-mail us a request at
3. Fax or e-mail us the documents at 1-514-931-7330 or

Thank you Erfa from Stop the Thyroid Madness and thyroid patients all over the world who KNOW what a superior treatment desiccated thyroid really is!

    Erfa are not produced in 500pc anymore. That will have a huge impact on prices in Norway (we have to pay the full price w/o support and the price have been very close per box 100 vs 500) so people are moving away from the brand. 🙁

      True, for a lot of reasons, people are moving away from Erfa. It’s like they really don’t care about their product anymore and any complaints fall in deaf ears and denial. 🙁

    I have Autoimmune Thyroid ( Hashimoto) I was wondering if Natural Desiccated Thyroid meds would be good for me and also does it help with the weight gain from the Thyroid..?

    If ALI is the ONLY supplier of dessicated thyroid in North America, Isn’t ERFA experiencing a shortage as well?

    I asked this question on the last blog post and got no response.

    (See blog post above this one)

    Janie, I just wrote them yesterday! I have a copy of the FDA form if you would like to post it somewhere on your site? They emailed me back within 12 hours and have been very pleasant. I’ve also heard good reports of their med from other boards… My only concern is pricing b/c the website states 500 count bottles except for 30mg which can come in bottles of 100. I’ll post later once I have that narrowed down. Thanks for all you do!

    I have been taking Thyroid (Erfa) for a couple of years now, and I know it is FAR superior to $ynthroid! I can’t compare it to Armour (not available here in Canada), but everything I have experienced or heard about it is that it works well. It is important to multi-dose (like Armour), and to go gradually with any increases (I have gone from a starting dose of 90 mg – which I was on far too long! up to 240 mg, divided into 3 daily doses). You have nothing to lose by trying it. I hope I don’t live to regret singing Erfa’s praises, and have to worry about shortages here in Canada! Good luck with it!

    Can anyone tell me how effective Erfa is compared to the old Armour (which worked well for me) and compared to RLC Labs Naturethroid/Westhroid? I just finally got some Westhroid last week right before the shortage, so my body is stil adjusting to it, but I think anything will work better for me than the new Armour, which was like taking nothing.
