Many patients have tried synthetic thyroid hormones, such as levothyroxine and liothyronine, and have found that Natural Thyroid is the only form that works adequately for them, reporting that they simply do not feel as well when they take levothyroxine alone or with liothyronine. Certain forms and strengths of Natural Thyroid are available only through compounding pharmacies. In addition, we can blend T4 and T3 pure powders in a specific ratio by prescription. Commercially available tablets contain fillers and excipients that may not be tolerated by all patients. When we compound customized dosages, we have the ability to omit any problem-causing inactive ingredients and substitute non-reactive fillers. We welcome your questions and the opportunity to help your patients.Thyroid Hormone Therapy for Women & Men:
Symptoms of hypothyroidism (low levels of thyroid hormone) include fatigue, cold and heat intolerance, hypotension, fluid retention, dry skin and/or hair, constipation, headaches, low sexual desire, infertility, irregular menstrual periods, aching muscles and joints, depression, anxiety, slowed metabolism and decreased heart rate, memory impairment, enlarged tongue, deep voice, swollen neck, PMS, weight gain, hypoglycemia, and high cholesterol and triglycerides. Yet, more than half of all people with thyroid disease are unaware of their condition.
Although both T4 (thyroxine, an inactive form that is converted to T3 in other areas of the body) and T3 (triiodothyronine, the active form) are secreted by the normal thyroid gland, many hypothyroid patients are treated only with levothyroxine (synthetic T4). Some hypothyroid patients remain symptomatic, and T3 may also be required for optimal thyroid replacement therapy. However, the only commercially available form of T3 is synthetic liothyronine sodium in an immediate release formulation which is rapidly absorbed, and may result in higher than normal T3 concentrations throughout the body causing serious side effects, including heart palpitations. Research indicates there is a need for sustained-release T3 preparations in order to avoid adverse effects.
A randomized, double-blind, crossover study found inclusion of T3 in thyroid hormone replacement improved cognitive performance, mood, physical status, and neuropsychological function in hypothyroid patients. Two-thirds of patients preferred T4 plus T3, and tended to be less depressed than after treatment with T4 alone. Patients and their physicians may wish to consider the use of sustained-release T3 in the treatment of hypothyroidism, particularly when the response to levothyroxine (T4) has not been complete.
