There are two hormones produced by the thyroid. These are T4—thyroxine, and T3—triiodothyronine. These hormones are important because they affect each and every cell and organ in your body. It is important to have the right amount. If you have too much thyroid hormone, it will speed up your body metabolism. If you have too little, it will slow it down.

If you doubt that two hormones can be so important, here’s what these hormones do in your body:
• Control your body’s metabolism which is the rate your body burns calories. They can cause both weight gain or weight loss.
• Cause your heartbeat to speed up or slow down.
• Increase or decrease your body temperature
• Change the rate at which food moves through your digestive tract.
• Have an effect on your body’s muscle strength.
• Determines the rate at which your body replaces drying cells.
• Works with the pituitary gland to make, store, and release TSH—thyroid stimulating hormone.

TSH is high when your body isn’t producing enough thyroid hormone. If you have a low TSH, it means your body is producing too much thyroid hormone.

Most of the hormone produced is T4, and only a small percentage of T3 is produced. Although the body produces a lot of T4, it is mostly inactive. T3 may be produced in small amounts, but it is the active hormone. Your thyroid gland produces a small amount of T3, it is produced in other parts of your body, mainly the liver. Your body produces T3 by converting T4 into T3. When this doesn’t happen, thyroid disorders occur. Here are the main reasons for lack of conversion.
• Mineral deficiency—This is one of the main reasons conversion doesn’t occur. These minerals include selenium and zinc. Make sure you don’t just find vitamins that contain them. You should be tested to see if a deficiency exists.
• Gastrointestinal difficulties—These usually cause problems with absorption of minerals. Even if you don’t have a deficiency in the proper minerals, if your body fails to absorb them, conversion will be hindered. Disorders such as leaky gut syndrome or candida infections can be a problem. It is extremely important to have a GI tract that is healthy.
• Liver Issues—About one-fifth of conversion takes place in your liver, so proper liver function is necessary for proper conversion amounts. Sometimes liver enzyme tests are normal, but other liver problems can occur. If you are exposed to toxins, they can reduce your liver’s ability to convert the T4 to T3. That’s when a liver detox program is important.
• Adrenal problems—These can cause high cortisol levels which have an effect on the conversion rate. Managing your stress level is one of the best way to control cortisol levels. Herbs such as Ashwaganda and Rehmannia can be helpful.
• Medications—Beta blocker medications such as Propranolol can inhibit conversion. Cortisosteroids also reduce conversion rate.

Sometimes it can be a challenge to determine the cause of the conversion problem. Some people have multiple problems. You can have a mineral deficiency and adrenal or digestive problems.

Your thyroid is a little organ with a huge responsibility. Thyroid hormones work hard to make sure your body’s metabolism works smoothly. When they aren’t in the proper amounts, especially for extended periods of time, then thyroid disorders occur. Do your part! Make sure you are tested regularly. Eat the foods that contain the necessary vitamins and minerals to help your thyroid working efficiently. When it does, you’ll feel great.
