It is a hormone that is naturally produced by the synthesis of thyroid hormone - thyroid hormone. In general, thyroid replacement drugs are generally taken. Your symptoms may take several weeks to improve. Learn more about how it works to help restore thyroxine balance
L-thyroxine (T4) is widely used by bodybuilders and fitness addicts for pre-competition cycles to get relief and overweight for weight loss. It increases metabolism and produces a general stimulating effect. However, this substance should be used wisely.
Levothyroxine is commonly used to treat hypothyroidism and is the preferred treatment for patients with hypothyroidism. Hypothyroidism often requires lifetime thyroid hormone therapy.

The thyronines act on nearly every cell in the body. They act to increase the basal metabolic rate, affect protein synthesis, help regulate long bone growth and neural maturation, and increase the body's sensitivity to catecholamines by permissiveness. The thyroid hormones are essential to proper development and differentiation of all cells of the human body. These hormones also regulate protein, fat, and carbohydrate metabolism, affecting how human cells use energetic compounds. They also stimulate vitamin metabolism. Numerous physiological and pathological stimuli influence thyroid hormone synthesis.
Thyroid hormone leads to heat generation in humans. However, the thyronamines function via some unknown mechanism to inhibit neuronal activity; this plays an important role in the hibernation cycles of mammals and the moulting behaviour of birds. One effect of administering the thyronamines is a severe drop in body
