Natural desiccated thyroid products

Background information

Desiccated (dried and powdered) animal thyroids have been used to treat hypothyroidism for over 100 years because they contain the T3 and T4 metabolic hormones. The traditional medical world has mostly switched to synthetic T4-only medication, but there are still a few remaining medication brands and several over-the-counter supplemental forms.

Prescription medications

Janie Bowthorpe of Stop the Thyroid Madness has a great overview of the common medications and their ingredients, saving me the trouble of writing this section :)

Thyroid UK also has a more UK-focused list of medications and their ingredients.

Since they aren't over-the-counter, Janie's how to find a good doctor page is a good resource, along with Mary Shomon's top thyroid doctor directory and RayPeatForum.com's medication discussion subforum.

Supplements containing desiccated thyroid

First, some disclaimers:

The supplement products are in a regulatory gray area in the US, so they have a few downsides:

I worked out the price-per-gram of desiccated thyroid (NDT) for the products that provide the weight of the ingredients. However, it's not a fair comparison because each brand will probably have a different potency based on the source of the thyroids and the processing methods.

If you use my Amazon buttons (for the products available on Amazon), they give me 4% at no cost to you. Or you can choose a charity beneficiary by using the AmazonSmile program.

I don't have a good sense of which brands are actually working for people, so please leave a comment if you've tried any.

Enough of my disclaimers, here's the products I've found, sorted alphabetically.

What about thyroid "support" supplements?

I didn't include the various "thyroid support/helper/booster/plus" type products that look similar to the desiccated thyroid products above. They have a different goal: they're meant to indirectly support the creation of thyroid hormone instead of actually including it. They often include things like:

In general I'd argue for researching the individual ingredients in the "support" supplements rather than the shotgun approach.
