It Produces Essential Hormones

The thyroid produces two important hormones, triiodothyronine (T3) and thyroxine (T4). These hormones essentially travel around the body and help regulate the metabolism of each part of the body, right on down to cell metabolism. T3 and T4 affect every tissue in your body. In other words, your thyroid is extremely important. And for great ways to take care of this all-important gland, here are 20 Ways to Have a Healthier Thyroid.

In addition to T3 and T4, your thyroid produces a hormone called calcitonin. According to the American Thyroid Association, this hormone is used to regulate the osteoclasts in the bones. Osteoclasts are essential for bone repair and upkeep—and they prevent hypercalcemia by helping keep your blood-calcium levels in check.

The thyroid hormone also helps keep your heart rate in a normal range—and at a normal strength. A study in the Embo Journal found that mice who had less access to thyroid hormones had a 20 percent lower heartbeat than those with a normal hormone exposure. This is because, with a deficiency, the arteries become less elastic and it takes longer for blood to circulate.

Having too much of the hormone can be a problem too; your thyroid controls how much T3 and T4 goes to your heart.

According to a 2013 review in the Journal of Clinical Research in Pediatric Endocrinology, studies have shown that affecting your BMR will directly result in a change of body weight.
