Thyroid hormone is probably the single strongest stimulator of the metabolism,Lycopene manufacturer, and therefore sluggish thyroid function is almost always associated with stubborn weight problems. Although decreased thyroid function can be due to problems with the thyroid gland itself, in many cases other factors are actually to blame. Let's examine the whole thyroid hormone system so that you can better understand where things can go wrong and how thyroid function can often be improved with lifestyle changes.

The stimulation of metabolism actually begins in a part of the brain called the hypothalamus - the master hormone controller. The hypothalmus senses the need for more or less thyroid hormone production and when more is needed, it signals the pituitary gland to produce a hormone called TSH (you may have seen this hormone listed on a blood test for thyroid function). Thyroid Stimulating Hormone (TSH) does what it's name suggests - it stimulates the thyroid gland to produce the inactive T4 hormone. When the inactive T4 hormone levels increase, it is taken up by the liver and converted to the active form of thyroid hormone,Safflower seed oil, known as T The T3 hormone then acts on receptor s on the cells of the body and causes the cells to produce more mitochondria, which can be thought of a microscopic power plants inside the cells. The mitochondria create energy for the cells (which when combined from millions of cells creates energy for the body as a whole) by burning stored sugar and fat.

When something goes wrong in the thyroid system,L-Lysine monohydrochloride manufacturer, the body does not burn fat and sugar as much,Shitake Mushroom Extract, so there is a tendency for weight gain. Since energy production is down, fatigue often sets in. And because there is not sufficient energy for certain cellular functions, healing and tissue regeneration may be depressed - this is most commonly noticed as hair loss and brittle nails.

There are several possible reasons why the thyroid system might not work as well as it should. First,Turmeric, there may not be sufficient stimulation of the body to cause the hypothalamus to start the process. The primary stimulator of the thyroid system is exercise - primarily short bursts of intense exercise. In other words, for healthy thyroid function, it is more effective to do interval training in which you do repetetive bursts of intense activity with rest in between, than it is to do long periods of low-intensity exercise, but any form of exercise is helpful.

Another possible problem is that the thyroid gland itself might be damaged, either by infection, or possibly by radiation exposure (either accidental exposure or intentional radiation of the thyroid for cancer treatment). In the case of actual thyroid damage, some type of thyroid medication will usually be necessary to compensate.

Yet another possible problem in the thyroid system is poor conversion of the inactive T4 hormone to the active T3 hormone by the liver. This typically occurs with poor lifestyle - excessive alcohol andor drug use, andor bad diet (especially a diet high in fats and animal proteins). The functioning of the liver can usually be greatly enhanced through dietary approaches, and improved liver function will translate to more efficient activation of thyroid hormone.

The active T3 hormone can actually be blocked at the receptor s on the body's cells and cannot send the signal for the cells to build additional mitochondria, and metabolism becomes sluggish. This is a common side-effect of estrogen and estrogen-like chemicals. The most common sources of estrogen interference with thyroid hormone are birth control medications and estrogen replacement therapy. If you have experienced weight gain and other thyroid-related symptoms since starting on birth control or hormone replacement, you may wish to consult with your physician about other options.

Finally, the formation of mitochondria can be interfered with by the presence of certain chemicals. Sodium benzoate, a preservative found in many processed foods and beverages (especially soft-drinks) can damage the genetic material within the cells needed for mitochondrial formation. Here again,E307, cleaning up the diet can be very beneficial to overall thyroid hormone function and the ultimate goal of weight control.

To sum things up, there are steps you can take to maximize the metabolism-stimulating effects of the thyroid. First,E306, regular exercise is important, and interval-training is the most effective for thyroid stimulation. Next, avoid excessive alcohol consumption, avoid drugs and medications except for those that are absolutely necessary, and keep fat and protein intake to a moderate level so as not to overwork the liver. In addition, you may wish to consult with your doctor if you are using any kind of birth control or hormone replacement medication containing estrogen. Finally, avoid the preservative sodium benzoate in order to avoid interfering with the production of your cellular "power plants", the mitochondria. In most cases these steps will gradually normalize thyroid hormone function and you will find that weight control becomes much easier. In a few cases, medical treatment for thyroid damage may be needed,Erythritol, but simple lifestyle changes are often the most effective means of improving metabolism.
