Many patients and physicians who practice alternative medicine, consider Dr. John C. Lowe a pioneer in the field of of thyroid disorders. Although his primarily field of study seemed to be fibromyalgia, he held many theories regarding hypothyroidism that many felt aligned with their values. According to this article, and many others on the web, Lowe believed that clinical tests that determined the T3, T4, and TSH levels within a patient were often false and could not be reliably trusted. Someone could still have hypothyroidism if there tests came back well within normal ranges. He recommended thyroid hormone therapy to his patients, even if diagnostic tests did not indicate a patient had hypothyroidism. Some of his patients seemed to feel better as a result of this extra thyroid hormone. Lowe believed that all hypothyroidism patients should take thyroid hormone replacement therapy as a cure for their thyroid issues, and according to the website, eventually developed Thyro-Gold, a dietary supplement that contains desiccated thyroid, in order to achieve this.


Thyro-Gold primarily contains thyroid gland powder from bovine in New Zealand along with other secondary ingredients such as 100 mg of L-Aspartic acid, 25 mg of 10% Extract of Coleus Forskohlii, and Glyceryl Behenate. The secondary ingredients of Thyro-Gold’s formula have been shown in scientific studies to have little benefits for the thyroid itself. Rather Thyro-Gold uses these as the frame for its vegetable capsule. One of them is also used as an herb powder although it is not as effective as some of the other more popular herbs such as Bladderwrack, or Cayenne Pepper. Studies, in particular, have shown the benefits of Ashwagandha for the thyroid. It is a bit surprising that Thyro-Gold does not include it in their formula.

The main ingredient, the thyroid extract, is touted as the best and most advantageous element for the thyroid, but many experts disagree with this statement. They caution against the use of thyroid extracts in supplements as dietary supplements are unregulated. Each capsule can contain any amount of thyroid hormones. One capsule may contain any range of T3 or T4 hormones, or possibly even nothing at all. If this capsule was produced by a regulated pharmaceutical company or obtained through a prescription, it would list the exact amount of hormone in each pill. However, as mentioned before, the unregulated nature of supplements makes the exact amount known.

This is the primarily safety aspect to be concerned with, with extracted thyroid hormones. If you accidentally take too much, you can experience many unpleasant symptoms such as high blood pressure, anxiety, sleeplessness, and increased heart rate. We would at least recommend talking to your doctor before deciding to take these supplements.

Another safety risk to consider is that extracted Thyroid Glands from bovine is Mad Cow Disease, which can be fatal to humans. While it is certainly rare for Mad Cow Disease to occur in New Zealand, as Thyro-Gold’s website so often says, it has occurred before contrary to what the website states. Mad Cow Disease and its variants are much greater risks in countries such as the United Kingdom, so it is safer that Thyro-Gold is sourced from New Zealand, but the risk is still there.

Company Practices

Thyro-Gold and its parent website has a lot of information about thyroid conditions and potential ways to alleviate the symptoms. Some of the information I have read so far looks good but there is some that is based on the theories of one man and not exactly supported by the major scientific community yet. Some of this information is regarded as pseudo-science from many scientists and experts. Furthermore there is no money-back guarantee. If this product does not work for you, it is likely you will not be able to get your money back.

We do like how Thyro-Gold’s website is made and is not bombarding you with marketing terms and stock images. The website has a personal touch to it. On the contrary, it does seem a bit outdated and could use a few improvements.


Thyro-Gold has the potential to boost T3 or T4 levels within your body. Since this is a dietary supplement, however, the exact amount of hormone in each capsule is unknown and unregulated. You will have to do a significant amount of experimenting to find the optimal dosage for your specific conditions. Some may need to take as many as 6 capsules a day.

Once you do find the right dosage, the additional intake of T3 or T4 hormones within each capsule may help your underactive thyroid but at most will just mask the real symptoms underneath. Many underactive thyroid users suffer from a lack of specific minerals, herbs, and amino acids. Thyro-Gold will do little to help you in this regard.


Thyro-Gold starts at $32.94 for one bottle without including shipping and handling costs. With all of these added together, the price you are looking at is at least $38. There is a slight discount for multiple bottles but this still makes it the most expensive thyroid supplement we have reviewed thus far.

    I don’t like it at all. I take it and it makes me feel kinda crappy. No energy, arms feel weak. I have e-mailed this company and they haven’t even bothered to return a response. The first email I sent about taking proper dosage was answered immediately, but when I wanted to get my money back…. it’s like they fell off the face of the planet. No responses whatsoever. I don’t trust this company at all. I think they are a little shady. I give them no stars!!!!!!
