Thyroid hormone production is regulated by a feedback loop between the hypothalamus, the thyroid gland and the pituitary gland. Hypothalamic thyrotropin-releasing hormone (TRH) stimulates pituitary thyrotropin (TSH) synthesis and secretion.
TSH improves the production and liberation of T4 and T3 from the thyroid gland. When the body is full with T4, it sends signals to TRH and TSH that it doesn’t need more thyroid hormone.
The production of T4 is sufficient but only a small dose of this is transformed into T3 which is the active form of thyroid hormone, the rest 85 % are T4 and they are inactive type of hormones.
After that, T3 becomes Free T3 and some of it into Reverse T3. The most significant hormone of all is the Free T3, because it is the only hormone that can be connected to a receptor and stimulate the metabolism to keep working, to keep us warm, to improve brain function and other bowels moving. Furthermore, this includes your heart rate and how quickly your body uses calories from the foods you eat. It has been noticed that the Reverse T3 increases when a person is under stress or those who have mercury toxicity.
The last but not least, there’s Hashimoto’s thyroiditis also called Hashimoto’s disease, is an autoimmune diseas a disorder in which the immune system turns against the body’s own tissues. The immune system attacks the thyroid. This leads to hypothyroidism, a condition in which the thyroid does not make enough hormones for the body’s needs.
If a doctor sees that several health problems have appeared in a patient’s body and organism, he should check all of these panels:
- Free T4
- Free T3
- Reverse T3
- Thyroid Peroxidase Antibodies (TPOAb)
- Thyroglobulin Antibodies (TgAb)
These ranges have been found to be optimal lab values for thyroid tests.
TSH 1-2 UIU/ML or lower (Armour or compounded T3 can artificially suppress TSH)
FT4 >1.1 NG/DL
FT3 > 3.2 PG/ML
RT3 less than a 10:1 ratio RT3:FT3
TPO – TgAb – < 4 IU/ML or negative
10 things to do to improve the thyroid function
Here are some tips that can prevent you from getting these disease:
- You should increase the intake of foods that contain Iron, Zinc Selenium, Vitamin D, and B vitamins.
- Tyrasine and iodine supplements help the FT4 and FT3 production.
- Eat vegetables and fruits, try gluten-free regime or diet.
- Sleep minimum 8 hours a day.
- Remove fluoride, bromide and chlorine out of your diet and surroundings.
- Check your digestive system.
