Your thyroid is very complex
As we’ve said many times, hypothyroidism (sluggish thyroid) is very common today. The reason why it is so common is there are many things that can have a direct or indirect effect on the thyroid.
A lot of things has to be working well in order for your thyroid to function normally. To be able to understand how many moving parts are involved in thyroid function it is important to have a basic understanding of how the thyroid works.
First of all, the hypothalamus which is a portion of the brain about the size of a pearl, releases a hormone called thyrotropin (TRH). The TRH from the hypothalamus tells the pituitary to release thyroid stimulating hormone (TSH). TSH then tells the thyroid how much thyroid hormone to make. Seems simple enough. However, the thyroid mainly produces a hormone called thyroxine which is referred to as T4. Unfortunately, T4 still needs to be converted into T3, which is the active form of the hormone.
As you can see, there is a lot that goes into normal thyroid function. The hypothalamus, pituitary gland and the conversion of T4 into T3 have to all be happening properly, otherwise there is a problem. Since there are so many moving parts, there are an abundance of things that can go wrong.
For example, a problem in the conversion of T4 into T3 can result in a sluggish thyroid. As I’ve mentioned, a majority of the thyroid hormone produced by the thyroid is T4. In fact, 90% of the hormones produced by the thyroid is T4. This means that in order for our thyroid to function properly, T4 needs to be converted into T3.
One of the problems is that in order to properly convert T4 to T3, you need the trace mineral selenium. This is why we have included selenium in our Thyroid Formula. The two main reasons why someone might be low in selenium are soil depletion and digestive issues.
Unfortunately, our soil today is nowhere near as mineral-rich as it used to be. Also, changes of soil pH has had a negative impact on selenium. This has resulted in lower selenium levels in foods.
If you have digestive problems such as Crohn’s disease, IBS or other inflammatory bowel disorders, you are at risk for low selenium. If you have a long history of antacid use then there is a good chance that you have low selenium.
If you are low in selenium, then your conversion of T4 to T3 is not as efficient as it should be and this may be why your thyroid is sluggish.
