The conversion of T4 to reverse T3 is increased in times of stress and illness. Reverse T3 causes fatigue, difficulty losing weight, brain fog, muscle aches and all the other symptoms of hypothyroidism.
Does hypothyroidism affect reverse T3?
There is an inverse linear relationship between the log TSH and the reverse T3. Patients with hypothyroidism plus illness may have a normal reverse T3 and patients with euthyroidism may have a low reverse T3. Reverse T3 is linearly related to bilirubin up to a bilirubin of approximately 171 microM (10 mg/dL).
Does high reverse T3 cause weight gain?
With less-than-optimal T4, hypothyroidism is usually characterized by low T3 and low rT3. Yet, sometimes, unexpectedly high rT3 can develop if you are hypothyroid. This can cause weight gain, and it may also be caused by weight gain.
Why reverse T3 is not important?
Reverse T3: Reverse T3 (rT3) is a byproduct of thyroid hormone metabolism. This test is not generally recommended for routine evaluation of thyroid disorders. Reverse T3 levels is elevated in sick euthyroid syndrome but has no other clinical value.
What does reverse T3 tell?
The Reverse T3 (RT3) test measures the inactive form of the hormone T3 or Triiodothyronine. Triiodothyronine is one of two major hormones produced by the thyroid (the other is T4, or thyroxine). Under normal conditions, the body converts T4 to T3 and RT3 in specific ratios.
What is normal range for reverse T3?
RT3 can be measured by a blood test. A level below 250 pg/ml (10 to 24 ng/dL) is considered normal.
What is the function of reverse T3?
Thyroid Status in Chronic Renal Failure Patients Reverse T3 (rT3) is a metabolically inactive form of thyroid hormone, which is generated from T4 via the type 3 5′-deiodinase enzyme. In addition to producing rT3, the type 3 5′-deiodinase enzyme is also responsible for decomposing rT3 into inactive diiodothyronine.
When should reverse T3 be checked?
Reverse T3 is a less common form of T3. This is often ordered in conjunction with a T4 test because it's a hormone produced from your T4's metabolism. If you're experiencing chronic stress, depression, brain fog, anxiety, weight fluctuations or hair loss, your doctor may recommend this test for you.
What is Wilson's temperature Syndrome?
Wilson's (temperature) syndrome, also called Wilson's thyroid syndrome or WTS, is a term used in alternative medicine to attribute various common and non-specific symptoms to abnormally low body temperature and impaired conversion of thyroxine (T4) to triiodothyronine (T3), despite normal thyroid function tests.

What happens if you get T3 instead of T4?
If a person gets T3 instead of T4, the body will have less T4 to convert to reverse T3 reducing its levels naturally and hypothyroid symptoms will slowly subside. The T3/rT3 ratio can be used to determine whether thyroid medication should be considered to correct high reverse T3 levels. Ideally the ratio of T3/rT3 multiplied by 100 should be in ...
What is the role of T3 in the circulatory system?
The major role of reverse T3 is to block the action of active T3.
Does cortisol increase T3?
High cortisol inhibits the 5- deiodinase enzyme type 1 and conversion of T4 into T3 leading to an increase in reverse T3. As a result, a person has low T3, too much reverse T3 or an improper T3/rT3 ratio. Both T3 and reverse T3 bind to thyroid hormone receptors. However, while T3 stimulates healthy metabolic activity of the receptors supporting your ...
Does TSH show T4?
TSH and T4 thyroid tests alone don’t provide us with information whether active T3 hormone reaches your cells and tissues and how effective it performs its metabolic action. It is the reverse T3 that is one of the important indicators that allows to evaluate how hypothyroid you are on a cellular level.

The first, and perhaps most common cause of high reverse T3, stems from calorie restriction and dieting. This one is so common because so many thyroid patients struggle with weight gain! You may be in that category if you are reading this now.
What is reverse T3?
Reverse T3 is created from T4 ( yes, the same T4 that is found in thyroid medications like Synthroid and levothyroxine ). Your body will either turn T4 into the active thyroid hormone T3 or the inactive anti-thyroid metabolite reverse T3. And it chooses which to produce based on a NUMBER of very important factors .
Why does inflammation cause T3 to spike?
Inflammation causes a spike in reverse T3 because it forces your body down the T4 to rT3 pathway (2) . Both systemic (meaning all over your body) and cellular (meaning low-grade inflammation which is hard to test for) can cause this problem. Most people with inflammation know that they have inflammation.
What nutrients can make T4 into T3?

However, this can have the opposite effect where there is a limited number of suppliers for a product, as suppliers can choose to increase prices unilaterally.
Is L-T4 synthetic?
Synthetic forms of L-T4, available since the 1950s, were introduced without any consideration of the need for randomised controlled trials. The existing porcine thyroid extracts were far from physiological, as the pig thyroid produces thyroxine (T4) and tri-iodothyronine (T3) at a ratio of 4:1, compared with the ratio of 14:1 in human thyroid.
Can you withdraw from L-T3?
Sudden withdrawal of L-T3 therapy is not supported, as clinical need should come before financial considerations. For patients who are long established on L-T3 and are thought to be stable, a change to L-T4 monotherapy should not be implemented without careful discussion. In such cases, change of treatment may result in significant instability of thyroid status and potentially undesirable clinical outcomes, which may prove more expensive than continuation with L-T3 therapy.
Is L-T4/L-T3 safe for pregnancy?
L-T4/L-T3 combination therapy is not recommended in pregnancy, patients over the age of 60 or patients of any age with known heart disease, as additional care is required to avoid over-replacement. Desiccated animal thyroid extracts remain not recommended in the management of hypothyroidism.

Perhaps someone with high reverse T3 needs to take specific supplements such as selenium, known to help bring down elevated rT3 levels. Perhaps they are smoking, and this is a good time to use their hypothyroidism symptoms as a motivator for finally giving up this very addictive and damaging habit.
What is the test for reverse T3?
However, there is a way to dispel that seeming invisibility by doing an important additional blood lab test, which is to measuring reverse T3 levels (rT3). This thyroid test already exists, and is normally available from most pathology laboratories.
What is the role of the thyroid gland?
Remember, one major role of the thyroid gland is to regulate body temperature, so it is a really good end-point from which to judge how functional the thyroid is; not just relying on how much hormone is floating around the body. Ferritin (Iron) Levels, rT3 & Hypothyroidism.
Why is T3 inactive?
Again, keep in mind that as a 'mirror molecule' of normal T3, reverse T3 is intrinsically inactive, because it docks onto receptor sites in an upside-down fashion.
Does hypothyroidism cause a lack of iron?
Many people with hypothyroidism don't produce enough hydrochloric acid in the stomach, which in turn can cause a wide range of nutrient deficiencies – including iron. The problem is that a lack of iron hampers the primary production of T4 and T3 by reducing the activity of the enzyme 'thyroid peroxidase', or TPO.
Does cortisol affect T4 to T3?
In fact, aside from inhibiting T4 to T3 conversion, these higher levels of cortisol also have a distorting effect on such conversion, causing the T4 to go into reverse T3 instead... which alas, then competes with normal T3 (triiodothyronine) at the receptor sites. All these factors add up to there being less of the active form of thyroid hormone, ...
Does stress affect T3?
This means there is less to convert to the active T3 format of this thyroid hormone. The Role Of Stress In Creating rT 3. Simultaneously, sources of stress - as mentioned above - can create higher levels of cortisol within our bodies, which tends to further inhibit the conversion of T4 to T3.
How often do you take T3?
Many patients on T3 therapy are given thyroid hormones 2-5 times daily throughout the daytime. There is a diurnal variation in thyroid hormone secretion with highest values between midnight and 4:00 am and the lowest values in the late afternoon.
What percentage of RT3 is made outside of the thyroid?

Exact same idea and conclusion as the last study except that it was done within the brains of rats. It is worth noting that in the cerebral cortex , rT3 is made preferentially as it may have a protective role.
What is the blood test for T4 and T3?
Blood tests for T4 and T3 can measure the total amount of active and inactive hormone or just the active fraction. Tests for the active fraction are called free T3 and free T4. Tests for both are called Total T3 and Total T4 or just T3 and T4. The free tests are preferable and used in most cases at present.
Can Graves disease cause high RT3?
Some who have Graves’ disease can also have high rT3 (but they are less commonly tested for it). An undiagnosed stressor on the body, like an illness, a medication reaction, or an infection. A lab error. This is especially true if you are on thyroid medication or have autoimmune thyroid disease.
Overview of thyroid hormones
The thyroid gland produces hormones that help regulate your metabolism. Specifically, they help control your metabolic rate through influencing systems like your heart rate, blood pressure, body temperate, muscle function, bone health, digestion, and brain development.
What is T3 medication, and what does it do?
People who have hypothyroidism typically need medication to increase their thyroid hormone levels. Thyroid hormone replacement medication serves to do just that: replace thyroid hormone in your body by mimicking the actions of your hormones.
When might a T3 medication be helpful?
Some people find adding a T3 thyroid medication preferable if they have not had success taking T4 on its own or are still struggling with unresolved thyroid symptoms. While T4 is the first line of treatment, it is not for everyone, and many people may benefit from the addition of T3 in their system.

How many T3 doses per day?
The majority of patients successfully using T3 use between three and four divided doses of T3 per day. Using divided doses of T3 clearly adds a lot of complexity to the life of thyroid patients. A further complication of the use of T3-Only is due to the suppressive effect that it can have on TSH.
How long does T3 stay in your system?
In contrast, the biological half-life of T3 is believed to be twenty-four hours. However, a single dose of T3 is rapidly absorbed and reaches peak circulating concentration in just two to three hours (2.5 hours is typical), after ingestion. Blood serum concentrations of T3 may remain somewhat elevated for six to eight hours.
How long does T4 last?
In the human body, the biological half-life of T4 is approximately seven days, which means a patient can take their entire daily dosage of synthetic T4 in one go, without any issues, because it is used up relatively slowly. In contrast, the biological half-life of T3 is believed to be twenty-four hours.
Can you add T3 to T4?
Some doctors attempt to perform simple mathematical calculations when they add T3 to their patient’s T4. They reduce their patient’s T4 dosage when T3 is added. Often there is no understanding that the added T3 is likely to have a suppressive effect on TSH and this is likely to downgrade any T4 to T3 conversion rate.
Is T3 only good for thyroid?
However, if all the necessary investigations have been performed, and all the thyroid hormone therapies have all been tried and shown to fail, then T3-Only can be a wonderful way of recovering your health. I know – I have done it, and so have thousands of other patients.
Is T3 blood test dangerous?
Attempting to do this by using thyroid hormone blood test results could even be dangerous, as all of these thyroid hormone test results may have no bearing on cellular activity. This point is highly relevant for those patients using T3 only and this is a major reason why using T3 is harder than the other hormones.
Can you use T3 on your own?
Endocrinologists, doctors and thyroid patients may wish to use thyroid blood test results to check the T3 dosage – but this simply will not work! Patients that are using T3 on its own will certainly struggle to get any value at all from thyroid blood test results.
