What is natural thyroid extract?

hypothyroidism, T3

Natural thyroid extract is made from the thyroid glands of animals and is used to treat a range of conditions associated with poor thyroid functioning. Synthetic hormones are often prescribed to treat these conditions, however there are some key differences between the synthetic and natural extract treatments.

What does the thyroid do?

The thyroid is actually a gland that produces hormones responsible for the development and correct functioning of many organs and bodily systems including the brain, the heart, metabolism, the muscular system and the digestive system as well as playing a part in regulating mood.

What’s the difference between synthetic and natural thyroid treatments?

The thyroid gland produces two major hormones: triiodothyronine (T3) and thyroxine (T4). Both play an important part in how your thyroid functions. T3 is the active hormone, the one that does all the grunt work, however the body can only produce it with the help of T4.

Synthetic thyroid treatments only contain T4 as T4 is the more stable of the two hormones and can be measured and encapsulated in standard doses. T3 is T4’s rebellious younger sibling and is not so easy to stabilise for use in drug manufacturing. Drug manufacturers reason that if you introduce more T4 into the body, more T3 will naturally be produced, addressing the thyroid disorder.

Where this reasoning falls down is that some people cannot convert T4 into T3 as easily as others, if at all.

This is why natural thyroid treatments contain both T4 and T3 – they introduce T3 directly into the body without relying on T4 alone to do the T3 conversion. This way you know, for sure, that you’ve increased levels of T3 in the body.

In a study published in the New England Journal of Medicine, researchers found that T3 improved mood and neuropsychological functioning when given to people with hypothyroidism.

About Our Compounding Medicines

"Excellent customer service"

To the Manager, I spoke to a lady in your office on Thursday who called to confirm my order. Unfortunately I did not hear her name properly. I asked her if she could expedite my order as I had run out that day and she said that she would do her best. To my overwhelming joy and surprise my vitamins arrived on Friday in Sydney when I was expecting it on Monday. This meant that I had my supplements over the weekend. Now I am reasonably sure that it took a concerted effort to make this happen. I therefore wanted to say a very big thank you to the lady I spoke to and all the people on your team that worked to make this happen. This is excellent customer service that is hard to find these days and wanted you and your team to know how much I appreciated it. Thank you again to you and your team.
