This may be even more relevant than T3 or T4. Especially if you are not making your own thyroid hormone, you are not ingesting T2 and likely to be low in it3.
There were some studies that showed people who had their thyroid removed, and it saw where their T2 levels were at that point. Basically, they had about half as much.
Even when they were taking thyroid hormone replacement, their T2 levels weren’t high enough compared to healthy populations.
We have also seen the same thing in pregnant women. This is where their levels are much lower than those of healthy populations, too4.
Entering the Thyroid Renaissance
This whole conversation around T2 is part of a much larger discussion I’ve been having lately, and after coining the term “the thyroid renaissance.”
Of course, this is something so important to me. Revisiting the thyroid, its value in the body, and challenging some of those past assumptions is essential. It’s our chance to come out with newer, better, and more impactful insight for your health!
Things like thyroid Hormone deficiency, thyroid hormone replacement weight loss, and the effect of thyroid hormone on muscles, they are all such crucial topics and deserve things written about them! But, let’s focus on T2.
Back in the 70’s, there was a lot of research done on T2. This was to see if it were an important part of thyroid hormone replacement and to see if it could be used to lower cholesterol.
What we have known for quite some time is that those with low levels of thyroid hormone often have higher levels of blood cholesterol.
Case Study: T2 Thyroid Example
In fact, this reminds me of a conversation I had with my doctors a few days ago.
We were discussing the case of a woman who was seen to be severely low in thyroid. With TSH scores in the 100s, and free hormones hovering around 0, with cholesterol levels in the 300 – 400 range.
This was a serious case.
