Thyroid Medication Explained

Many people are taking a thyroid replacement medication like Thyroxine but still feeling most of their original symptoms.

Your medication may have a different brand name such as Euthyrox, Eutirox, Letrox, Levaxin, Lévothyrox, Levoxyl, L-thyroxine, or Thyrax. I am going to use Thyroxine as the term that counts for all these brand equivalents.

Today I’m going to explain…

  • Why you may not be feeling like your medication is working,
  • How we test your thyroid when you are on medication,
  • How we improve your response to the medication.

Many of our patients say…

“Thyroxine may be a life saving medication, but it’s not a life enhancing.”

Not as simple as popping a pill

This medication must be taken first thing in the morning, 45 – 60 minutes before food. If taken incorrectly, any calcium in your food will bind to it and make it unavailable to your body. So the very first thing to check is that you are taking it correctly.

Once the medication is absorbed into your bloodstream, it travels around the body and will be converted at various sites. Enzymes in organs like the liver, brain, and heart, convert thyroxine (T4) into T3.

For most people with hypothyroidism, the body converts thyroxine into sufficient T3. But there’s evidence this doesn’t always happen.

This conversion process can be inhibited by nutrient deficiencies, or insufficient enzyme production.

So how can we check that?

How Thyroxine works

Thyroid medication is just T4.

T= tyrosine 4 = 4 molecules of iodine.

In your body, it will go one of 2 ways. If all is well, there are enough nutritional co-factors available, and no adverse factors happening at the time, then most of it should turn into T3.

However, if there are low levels of nutritional co-factors due to a poor quality diet, high stress, pregnancy, fasting, other medications, or other factors which I will outline below, then most will turn into the inactive reverse T3, called rT3 for short.

Reverse T3 can’t be converted into T3, so it basically takes up space and interferes with the healthy production and conversion of regular T3.

Have you had rT3 checked? It isn’t on the medicare scheme in Australia, so it is not a standard test.

However, it is vital to check, because if your medication dose is too high because you can’t convert T4 to T3, this results in pooling of unavailable hormones, complicating the situation even more!

The VITAL test no-one tells you about

There is actually still another step to your thyroid medication, and that is how well it can move from your bloodstream into the cells of your body. Because that’s where we actually need it – no point having great blood work if you can barely get out of bed in the morning!

The active T3 hormone knocks at the door of the cell wanting to be let in to do its job. However, sometimes it isn’t allowed in. This can occur from chronic inflammation, heavy metal excess, and a stiffening of the cell wall. It coincides with insulin resistance and leptin resistance.

We check this by doing a reflex test.

The quality of your reflex shows us if you adequate or low thyroid hormone in the cells of the muscles, brain and nervous system. It completes the full picture when combined with a thorough blood work up, symptom checking, and health history appraisal.

Here’s an actual ThyroFlex Test report…

The Treatment

First we look into the reason behind the slow reflex.

Stress – stress hormones wreak havoc on the conversion of T4 to T3 (look at you go!) We test stress hormones and treat as required to calm these down.

Nutrient co-factors – Iodine, Selenium, Zinc, Vitamin D, Iron, and B vitamins need to all be on point and are tested in a variety of ways ranging from blood tests to saliva samples. Supplementation is used to correct deficiencies.

The reflex test will tell you if your medication is actually working for you. And the GREAT NEWS?

It’s FREE in your initial consultation.
