Virtually all doctors, when they are checking a patient’s thyroid levels, send out tests for TSH, thyroid stimulating hormone, and free T4, the form in which the thyroid hormone is stored. But they do not measure the forms of thyroid “free T3” and “reverse T3” that is the form of thyroid that actually determines how a person feels and functions. Low T3 can cause mental confusion and cognitive difficulties even if T4 is high if a person’s ability to convert T4 to T3 is compromised. Symptoms include cold hands and feet, as well as low body temperature, fatigue, memory loss, mental confusion, depression, thinning hair and eyebrows, and others.
Here’s an expert in thyroid speaking about this.
Ninety-nine percent of doctors prescribe Synthroid or Levothyroxin, which are both T4-only synthetic thyroid replacements. For some people that’s okay, but many people’s bodies can no longer convert T4 into T3, so synthetic thyroid can’t work for them. Many people are in nursing homes because despite normal labs for T4 and TSH, they’re low in T3.
For over 100 years, the best and most natural remedy for low thyroid was dessicated porcine or bovine thyroid. Natural dessicated thyroid most closely resembles what the human body makes and contains T1, T2, T3, T4 and calcitonin just like human thyroid. Most people have significantly better results on natural versus synthetic thyroid.
Here are some things you can do for yourself to get an idea of whether or not thyroid is problematic for you. Much of the information is taken from the book and/or website, www.stopthethyroidmadness.com.
- Take your temperature. If your waking temperature is below 97.6 and your afternoon temperature is below 98.6 you may be low in T3 and may need natural desiccated thyroid or thyroid support. See Dr. Rind’s site for more info.
- Visit www.stopthethyroidmadness.com and similar sites and books on natural thyroid to see if you have other symptoms of low thyroid even if your labs are normal
- Get tested for thyroid including free T3, free T4, reverse T3, and thyroid antibodies (anti-TPO and TgAb)
- Find a doctor who is familiar with desiccated thyroid (such as Nature-throid, Westhroid, Armour, and Canada’s Erfa thyroid all natural), and find a doctor who will dose on symptoms, such as low temperature and energy levels, and not rely solely on lab tests.
- Correct iodine deficiency, which is a primary cause of low T3. Build up the thyroid with iodine and other thyroid-supporting supplements such as selenium and L-tyrosine combined together. Most naturopaths recommend Iodoral, which is available online. ThyroPower by Physician’s Strength is also available online.
