home thyroid tests The Thyroid is a gland that is located in your neck. It produces hormones to help with energy and metabolism. TSH is the main thyroid hormone most people know about, but what about T3 (triiodothyronine)? T3 is named based on the number of iodine molecules attached to the thyronine molecule. T3 and T4 are also produced by the thyroid gland and are just as important to regular your metabolism, body temperature and heart rate.

Most of the T3 your body makes binds to proteins, the rest of it (that does not bind to proteins) is called Free T3 which circulates unbound throughout your blood. When you do a thyroid blood spot test it is looking it is looking for Free T3 levels. A Total T3 test will test for both free and bound T3.

Symptoms of low T3 can be: fatigue, weight gain or the inability to lose weight no matter what you try, feeling cold, dry skin and hair, hair loss, poor growth, acne, increased heart rate, poor bone health, low neurotransmitters, infertility, miscarriage, high cholesterol, mood swings and even depression.

High T3 levels may indicate: Grave’s disease, hyperactive thyroid, thyroiditis, goiters, thyroid cancers

Low T3 levels may indicate: a low T4 level (T4 is needed in abundance to convert in the liver to T3) , a chronic illness is present, hypothyroid, starvation.

The main medication on the market that treats a low T3 level is Liothyronine. This is totally differnt then Synthroid or levothyroxine which is a T4 medication and only supports T4 thyroid problems.

We get many people contacting our clinic stating they are taking Synthroid and it helps to a point. When we test their Free T3 levels it indicates T3 may be needed too.
