3.3 Diiodo-L-Thyronine: The Inactive yet Effective Thyroid Hormone

Between the hormones produced by the thyroid glands, medical experts of the past believed that T2, otherwise known as Diiodothyronine, is inactive and the least important. This misconception has led to the development of advanced studies involving T3 and T4, but not T2. After several decades since the discovery of thyroid hormones, a group of scientists started to develop interest over the potential activities of T2 in metabolism. Though considered inactive, the group discovered that the compound directly acts on the mitochondria of the cells, making it one of the most effective metabolism activators. With several independent studies confirming the claim, experts have developed 3.3 Diiodo-L-Thyronine, a synthetic form of T2 which can be included in health supplements formulations.

What is 3.3 Diiodo-L-Thyronine?

Essentially similar with the naturally-occurring T2 hormone, 3.3 Diiodo-L-Thyronine is believed to be a potential mediator of thyroid hormone production. Unlike T3 and T4 hormones, studies show that body cells, especially the liver which is responsible for fat metabolism, responds more readily with T2 stimulation which leads to more efficient breakdown of fat molecules. There are only a few studies on 3.3 Diiodo-L-Thyronine as of today due to the notion that it is an inactive thyroid hormone but with the rise of interest on the compound, more advanced and reliable studies are expected to be completed in the next few years.

Health benefits of 3.3 Diiodo-L-Thyronine Supplementation

Claimed health benefits associated with regular supplementation of 3.3 Diiodo-L-Thyronine include the following:

  • It may increase muscle size

One significant finding on 3.3 Diiodo-L-Thyronine which is principally related to the musculoskeletal system is the fact that it works on the mitochondrion, thus increasing muscle fiber twitching of muscle tissues. Rapid muscle twitching results to the reduction of triglycerides in the muscle fibers and the improvement of ductility and strength. When the fat mass in muscles reduce due to twitching, muscle size generally increases.

  • It improves metabolism

Slowed metabolism is very common among individuals exposed to unhealthy environment due to inevitable changes in hormonal production. By fixing Thyroid-Stimulating Hormone production through 3.3 Diiodo-L-Thyronine Supplementation, metabolism is expected to shoot up, leading to several health benefits which include weight loss, reduction of risks on cardiovascular conditions development and preventionof Diabetes Mellitus.

  • It promotes fat loss in target areas

While fat distribution normally follows a pattern, some individuals suffer from conditions where fats are only concentrated in certain areas of the body but not in some other regions. Studies show that 3.3 Diiodo-L-Thyronine helps promote fat loss in specific areas of the body which are susceptible to unequal fat distribution which include the arms, the thighs and the abdomen.


In terms of safety, there are no side effects associated with the use of 3.3 Diiodo-L-Thyronine. There are, however, possibilities of developing untoward symptoms when the compound is taken beyond recommended doses.
