What is Liothyronine Sodium?

New to is Liothyronine.  Though we recommend using it only for research purposes, as is the case with all of the products that we sell, Liothyronine Sodium has been approved for prescription use and marketed to treat hypothyroidism.  You may already know but hypothyroidism is a condition in which the thyroid gland doesn’t produce enough thyroid hormone. Not producing enough thyroid hormones can lead to serious problems with the metabolism, often resulting in obesity.  Subsequently, it’s not rare to find people struggling with hypothyroidism will also have heart problems.

Liothyronine Sodium can presumably be used for more than just under active treatment though.  The man-made hormone has rare side effects, most of which aren’t too severe, and can be used to prevent other issues like goiter and rare thyroid disorders.  

Side Effects

Like with many prescription drugs, the only really serious side effects that you need to concern yourself with are brought on by poor use practices.  For example, if you ingest more than you are prescribed, you’re going to wildly increase the risk of heart attack-like symptoms. Understand there is no correlation between Liothyronine Sodium supplementation and cardiac arrest but if you use more than prescribed, you may experience some shortness of breath and even chest tightness.  It’s extremely rare to experience these side effects when using Liothyronine in moderation.

The common side effects are far less serious.  There are two real side effects that nearly half of all users have recognized.  The first of which is something you’ve almost come to expect from prescription medication: Temporary nausea.  The upset stomach feeling, particularly if you haven’t had much to eat, is one that we’re all familiar with. The second common side effect is not something you’d expect.  In fact, it is a reason that many people, women in particular, request alternate prescriptions. Hair loss. That’s right. Moderate hair loss is completely normal and while not everybody experiences it, enough users to make it noteworthy do notice some hair loss in the shower.

Liothyronine Sodium Sounds Good… Why Research?

Good question.  As of late, scientists have been exploring alternate uses for Liothyronine and Liothyronine sodium.  It turns out that cancer cells seem to react favorably when introduced to the substance. Just a few months ago, a research study was completed and published showing that Liothyronine Sodium changes the makeup of tumors in the breasts and in the pancreas.  This is groundbreaking.  While it doesn’t cure the patient of cancer, it certainly seems to alter the tumors to the point of growth prevention, or at the very least, it would seem to slow the process.  Now your wheels are spinning and the gears are going. It is very much within the realm of possibility that we will soon be able to figure out how to leverage Liothyronine Sodium in the war against cancer.  Obviously more work needs to be done and we’re a ways off, but the groundwork is there.
