I’d like to Try Natural Desiccated Thyroid but Can’t Have Pork

I have been asked many times before:

“I’d like to try NDT but I’m vegetarian, what are my options?”

“I’d like to try NDT but don’t eat pork for religious reasons, what can I do?”

Let’s explore the options.

Armour Thyroid Medication

T3 Appeal

Many of us have read about how well some people do on a type of thyroid medication called Natural Desiccated Thyroid (NDT), particularly if they do not respond well to T4-only Levothyroxine or Synthroid for example.

For those who don’t consume pork though, this medication made from dried porcine gland can pose a lot of questions.

Whilst NDT tends to work well because it’s so similar to your own thyroid, containing what your own thyroid would be giving you (direct T4 and T3), for those who don’t consume pork, it’s not as simple.

For some, avoiding pork, being vegetarian or vegan is a lifestyle choice, cultural or religious instruction.

So What Can You Do?

One alternative is the combination of synthetic T4 (such as Levothyroxine and Synthroid) and synthetic T3 (Liothyronine) medication, but it’s worth being aware that Tirosint (a T4 Levothyroxine medicine) can contain gelatine, so always check what you’re given. Synthetic T3 medication can be prescribed alongside your T4, though is often harder to get than regular T4-only medication. Many people see an endocrinologist or private practitioner for this medication. Much like NDT.

The T3 and T4 combination is often reported to be more successful at treating hypothyroidism and the associated symptoms than T4 alone, since you are not relying on your body to convert the T4 in to T3 (T3 being the most active thyroid hormone and one we also need to feel well).

Compounded biodentical T3 and T4 could also be an option. A reader contacted me to suggest this as she is vegan and prefers this preparation to actual NDT medication, as it lets her sleep better.

Update as of September 2022: Compounding of thyroid medication has been suspended or ‘banned’ by the FDA. Thyroid patients are trying to upturn this by emailing at [email protected]

Another option, if you can’t have pork but can consume other meat, is a bovine NDT (made from cows). There are ‘over the counter’ bovine NDT products called Thyrogold and Thyrovanz, referred to as a ‘dietary supplement’. However, I always recommend that people use great caution when ordering thyroid medication or glandular containing supplements online. The best option is always to have a doctor prescribe this medication for you.

Another alternative is to consider looking at NDT in a different way. Thyroid hormone is needed in order for you to live and function. Does this take precedence over your what your religion, culture or morals dictate?

Well, that’s for you to decide.

You could speak to a religious figure at your church, temple, mosque etc. and discuss this subject with them if you’re unsure about what to do.

One thing is certain, though. It’s completely your decision and only you know what you feel comfortable with.
