Information about the drug

Thyroid hormones play a very important role in human organisms. Thyroid hormones have a wide range of actions and are particularly necessary for the normal development of the organism. They have stimulating action on the rate of oxygen consumption by both the whole organism and separate tissues. Also, thyroid hormones play an important role in the regulation of the cardiovascular system's functioning. They control heat production, take part in the maintenance of normal functioning of the respiratory center, stimulate the synthesis of many structural proteins in the body.

Synthroid is a drug that includes a synthetic analogue of the human thyroid hormone (Levothyroxine), also known as T4. The history of using this substance has many years, it is mostly used for the medical treatment of a disease called Hypothyroidism. Hypothyroidism is the result of any condition that results in thyroid hormone deficiency. Two well-known examples include Iodine deficiency and primary thyroid disease. Iodine is absolutely necessary for the production of thyroid hormones in our organism. Without adequate intake of this substance, thyroid hormones cannot be synthesized. In the case of primary thyroid disease, the main cause of hypothyroidism is an inflammatory disease of the thyroid that destroys the gland cells, which produces hormones and leads to hypofunction of the gland.

Levothyroxine (T4) is involved in many metabolic processes, including processing and absorption: Carbohydrates; Fat, and protein. Thus, the lack of this hormone leads to a number of undesirable consequences, in the form of obesity, low energy levels, poor physical endurance, and even lethargy.

Levothyroxine (T4) is less active than its predecessor (T3, triiodothyronine) several times. According to this, only T4 is used in pharmacology.

Well knowing the properties of this substance it is widely used not only for therapeutic purposes, Levothyroxine also takes an active and important part in the sport. The main users of Levothyroxine are athletes for whom it is important to speed up the metabolic process and reduce the total amount of body fat.

Bodybuilders also use T4 in the cycle of the cut, to give the muscles a more relieved appearance by eliminating subcutaneous fat.

At the time of burning fat reserves, an athlete using Levothyroxine remains quite energetic, even despite strict dieting, which is an integral part of the preparation for the performance. In the body fat stores a huge amount of calories and fat-soluble vitamins. When Levothyroxine interacts with fat, the process of lipolysis starts which provides the entire organism with energy.
