What does Liothyronine 25mcg (GearLio) do?
Liothyronine or T3 (L-triiodothyronine) is one of the thyroid hormones, synthesized and secreted by the thyroid gland. T3 contains three iodine atoms and is derived from peripheral monodeiodination of T4 (at the 5th position of iodothyronine nucleus); T3 is the main hormone delivered and used by the tissues. Thyroid hormones increase oxygen consumption by the majority of tissues throughout the body; both T3 and T4 increase the BMR (basal metabolic rate) and the metabolism of lipids, carbohydrates, and proteins. Therefore thyroid hormones exhibit significant effects on every organ system and are crucial in the CNS development.
Liothyronine 25mcg (GearLio) is used mainly as a replacement or supplemental therapy in patients with hypothyroidism, except for transient hypothyroidism during the recovery phase of subacute thyroiditis.
How does Liothyronine 25mcg (GearLio) work?
T3 is a tyrosine-based hormone produced by the thyroid gland. Although the major form of thyroid hormone in the blood is thyroxine (T4), T4 is converted to the more active T3 form (liothyronine) by deiodinases in peripheral tissues. Thyroid hormones are essential for the development and differentiation of all cells in the human body; they regulate protein, fat, and carbohydrate metabolism, as well as how individual cells utilize energetic compounds. Thyroid hormone derivatives initiate their downstream effects through binding to nuclear thyroid hormone (TR) receptors. In a bound active state, TR can regulate gene expression via direct interaction with DNA components. Various intercellular signaling pathways lead to a direct effect on metabolism; T3 promotes an increase in BMR, protein synthesis, and sensitivity to catecholamines (e.g. adrenaline).
How should Liothyronine 25mcg (GearLio) be taken?
Cytomel should be taken orally, with or without food following the prescribed dosage regimen. It works best when taken at the same time each day and for at least a few weeks to relieve symptoms of a patient’s condition.
Cytomel should be taken 4 hours apart from calcium salts (like calcium carbonate), cholestyramine, or sucralfate. Double doses should not be taken at any time; in case of a missed dose – one should be taken as soon as possible unless, it is time for the next dose, in which case the missed dose should be skipped and regular dosing schedule followed.
Safety Information of Liothyronine 25mcg (GearLio)
Cytomel is contraindicated if: the patient is allergic to any ingredient in cytomel; in the presence of a history of heart attack; the presence of untreated thyrotoxicosis or uncorrected adrenal gland problems.
Medical assistance is required if any of the following apply:
• The dose should be adjusted in case of any of the following: tremor, nervousness, insomnia, headaches, change in appetite, weight loss, diarrhea, increased sweating or sensitivity to heat, increased heart rate, chest pain, and shortness of breath;
• Concomitant treatment with blood thinners will require dosage adjustment in the blood thinner;
• Diabetes. Cytomel may affect blood glucose levels;
• Elderly patients may be more sensitive and should use Cytomel with caution;
• T3 may cause temporary hair loss in children;
• T3 can be passed into breast milk; breastfeeding or pregnant women should consult a doctor whether treatment with Cytomel should be continued;
• Thyroid function test may be required on a regular basis;
• Doctors should be informed if patients are undergoing therapy with T3 prior to receiving any medical or dental treatment, emergency care, or surgery;
• Cytomel will be taken for life unless a patient is suffering from temporary low thyroid activity associated with thyroid inflammation.
How Liothyronine 25mcg (GearLio) controls weight and energy levels.
T3 directly controls the body’s metabolic rate.
When the amount of thyroid hormones produced in the body falls, the rate of metabolism falls with it. In this regard, the amount of circulating T3 is more important than that of T4.
Because of the reduced metabolic rate, low thyroid functioning results in difficulty reducing body weight. When overweight individuals adopt healthy, low-calorie diets and take up regular exercise but still cannot shed weight, the most likely reason is low metabolic rate caused by low T3 levels.
Even a 10% reduction in metabolic rate can make weight loss very difficult. However, available clinical data suggest that most people who find it difficult to lose weight have 15 – 40% reduction in metabolic rate.
For this group of people, T3 is the magic remedy for losing weight.
Unlike stimulants like caffeine and synephrine, T3 increases the rate of metabolism without such side effects as jitters. It does not make the user “hyper”. Instead, it simply energizes the user without the crash that comes from overstimulation with stimulants.
Increased Growth Hormone Secretion for Liothyronine 25mcg (GearLio).
Invitro, animal and human studies have all demonstrated that T3 administration increases growth hormone production. Since GH is calorigenic, elevated GH may contribute to some of the fat burning associated with T3 administration.
What is Side effects for Liothyronine 25mcg (GearLio)?
Most common side effects include partial, temporary hair loss in children; tachycardia, jittery feeling, and weight loss.
In case of any of the following severe side effects, a patient should seek immediate medical assistance: allergic reaction, changes in menstrual period, chest pain, difficulty breathing, irregular heartbeat, leg cramps, diarrhea or vomiting.
