What Is T3?

T3 (Liothyronine Sodium)

T3 (Liothyronine) is a naturally occurring hormone produced by the thyroid. It is important for normal energy and metabolism. For a variety of reasons, the body may not produce enough of this hormone on its own. In these cases, liothyronine is taken to replace the body’s natural thyroid hormone.

More information on T3

The thyroid hormone T3 liothyronine, otherwise known as T3, plays a crucial role in our chemical makeup which controls virtually every physiological process in our bodies. Our metabolism, growth, and overall physical development are affected by this. Moreover, this hormone also has an immediate effect on our bones and central nervous system such as neurotransmitters as well as our bone’s rate of growth. In addition, it has a direct effect on the development of embryos and fetuses. T3 liothyronine is regarded as the powerful type of thyroid hormone. Consequently, it acts on the body to increase the basal metabolic rate, have an effect on protein synthesis and also increase the body’s level of sensitivity to catecholamines (like adrenaline) by permissiveness. The thyroid hormones are essential to proper growth and differentiation of all cells of the human body. These types of hormones also regulate protein, fat, and carbohydrate metabolism, which affects how human cells use energetic compounds.

Facts about Thyroid Hormone T3 liothyronine

Among all the thyroid hormones that are produced, nearly 20% of such hormones areT3 liothyronine. The extra 80% is taken up by the thyroxine hormone. The impacts are also almost 4 times greater than other hormones released in the. T3 liothyronine is produced once the iodine atom is removed from the carbon atom number five inside the thyroxine outer layer. Basically, T3 liothyronine is close to 1/40 of the hormones created by the thyroid. Its life span is merely 2 ½ days compared to the life span of the thyroxine hormone which is almost 6 1/2 days.

The Production and Location of T3 liothyronine

T3 liothyronine and thyroxine are bound to three forms of proteins in our plasma; both these hormones are bound by serum albumin due to its high capacity. Whenever our pituitary gland releases stimulating hormones (TSH), liothyronine will likely then be activated. If there’s a large activation of T3 and thyroxine in our blood plasma, the development of the Thyroid Stimulating Hormone will probably be lowered. Thus, when T3 liothyronine and thyroxine are lowered, TSH will increase as well. Consequently, our body has set up a feedback control system to ensure that the hormones created by our thyroid are controlled in our blood stream.

The Purpose of Hormone T3 liothyronine

The Thyroid Hormone T3 liothyronine is important to improve our body’s oxygen and energy ingestion. The energy intake, or minimum caloric requirement, is needed by our bodies to preserve life during an individual’s period of rest. Also, liothyronine is a powerful hormone which is necessary for just about every major organ and tissue within the body excluding your spleen and testis. The thyroxine hormone, which is much less active, is only waiting to be converted into T3 once the body requires it.

Therapeutic actions:

The mechanisms by which thyroid hormones exert their physiologic action are not well understood. These hormones enhance oxygen consumption by most tissues of the body and increase the basal metabolic rate and the metabolism of carbohydrates, lipids and proteins. Thus, they exert a profound influence on every organ system in the body and are of particular importance in the development of the central nervous system.

What is T3 used for?:

Cytomel is prescribed for treating low thyroid function. It is also used to treat or prevent different types of goiters, as an aid to diagnose certain thyroid conditions, or to treat patients who are allergic to other thyroid medicines. It may also be used for other conditions as determined by your doctor.

Contraindications and cautions:

Thyroid hormone preparations are generally contraindicated in patients with diagnosed but as yet uncorrected adrenal cortical insufficiency, untreated thyrotoxicosis and apparent hypersensitivity to any of their active or extraneous constituents. There is no well-documented evidence from the literature however, of true allergic or idiosyncratic reactions to thyroid hormone.
