Thyroid Hormones

Medical Aesthetics & Laser Spa Serving Sherwood Park, Spruce Grove, St. Albert & Nearby Edmonton, Alberta

Thyroid hormone determines the metabolic rate and energy production levels for every cell in your body. The brain senses the amount of thyroid hormone and energy needs and sends Thyroid Stimulating Hormone (TSH) to the thyroid gland. This stimulates the thyroid to produce T4. This T4 travels through the blood to our cells where it is converted into T3 the ‘active’ form of thyroid hormone which turns on energy production and heat generation in our cells

TSH is often used to determine thyroid function. TSH is a useful measure of thyroid hormone balance in many people. Some people however, only truly feel well with thyroid dosing that will suppress TSH. In these cases, TSH only gives part of the thyroid picture.  Free T3 and Free T4 complete this picture showing what is actually produced by the thyroid and what is available for the cells to use.  Your coach and physician will guide you in this area.  The main goal is always to optimize well-being and keep you safe.

As we age, the conversion of T4 to T3 suffers from factors in our environment such as:

    • pesticides
    • stress
    • mercury
    • infections

The result is lower levels of T3 followed by a slowing of our metabolism.

Signs/Symptoms of Thyroid Deficiency:


      • cold intolerance
      • low energy / fatigue
      • difficulty losing weight
      • unusual hair loss
      • cracking nails

To function effectively thyroid also requires a properly functioning adrenal system.  See our Stress page for more details.

These are the most common thyroid medications.

      • Desiccated Thyroid—has both T3 and T4 thyroid hormones and works best in most people. It is obtained from animal sources and is very well absorbed.  It is taken on an empty stomach half-hour before eating in both the morning and mid-afternoon, when energy levels are lowest.  This is our preferred method of treatment.
      • Synthroid—has T4 which the body then converts to T3, for some people this option seems to work best. It is a sustained release pill therefore it is only taken once in the morning on an empty stomach.

If your physician tests your thyroid, please ensure that you do NOT take your thyroid medication that morning as the results will be inaccurate and likely out of normal range.

Signs/Symptoms of Excess Thyroid:

            • heart palpitations
            • shakiness
            • anxiety
            • insomnia

If you experience any of these symptoms, decrease your thyroid dose by 1 pill immediately. For specific doses relevant to your treatment please refer to your patient checklist.
