1.Levothyroxine, also known as L-thyroxine or T4, is a synthetic form of the thyroid hormone thyroxine, usually secreted by the follicular cells of the thyroid. It can also be used to treat thyroid hormone deficiency and occasionally prevent the recurrence of thyroid cancer. Like its naturally secreted counterpart, levothyroxine is chemically chiral L-shaped. The related drug D-thyroxine (D-thyroxine) was used to treat hypercholesterolemia (elevated cholesterol levels) in the past, but was withdrawn due to side effects from the heart.
2.L-Thyroxine is a hormone, and your body only converts it to T3 at the necessary rate, so it can be considered to be milder and safer than T3.
3.L-thyroxine is an excellent fat burner, because its metabolism will be greatly increased. You can slack off when dieting before the game, because when you consume a lot of calories, it will still burn fat because the metabolism will be dull and boring.
4.L-thyroxine is widely used by bodybuilders and fitness addicts in the pre-match cycle to reduce stress, and is also used by overweight people to reduce weight. It increases metabolism and produces general stimulation. However, the substance should be used wisely.
L-thyroxine can be used to treat hypothyroidism and is the preferred treatment for hypothyroidism patients who often require lifelong thyroid hormone therapy. It can also be used to treat goiter to reduce the ability of thyroid stimulating hormone (TSH),which is considered to be a hormone that induces goiter. Levothyroxine is also used in the interventional treatment of patients with nodular thyroid disease or thyroid cancer to suppress the secretion of thyroid stimulating hormone (TSH).
