Thyroid hormones are naturally synthesized in our body, but since the molecules are not complex, many pharmaceutical companies make the synthetic variety of the hormones. There are two basic types of thyroid hormones- T4 known as levothyroxine and T3 known as liothyronine. Both are manufactured and stored in the thyroid gland.
Thyroid hormone from the pharmaceutical companies are obtained in 2 ways.- either derived from animal thyroid gland (bovine or ovine sources) or made synthetic. In the USA, the content and quantity of iodine in the thyroid preparation is well regulated.

Thyroid hormone preparations belong to two categories: (1) natural hormonal preparations derived from animal thyroid, and (2) synthetic preparations. Natural preparations include desiccated thyroid and thyroglobulin. Desiccated thyroid is derived from domesticated animals that are used for food by man (either beef or hog thyroid), and thyroglobulin is derived from thyroid glands of the hog. The United States Pharmacopeia (USP) has standardized the total iodine content of natural preparations. Thyroid USP contains not less than (NLT) 0.17 percent and not more than (NMT) 0.23 percent iodine, and thyroglobulin contains not less than (NLT) 0.7 percent of organically bound iodine. Iodine content is only an indirect indicator of true hormonal biologic activity.

One should take caution if considering using this drug. Liothyronine Sodium (T3) comes with an extensive list of warnings and precautions which are not to be ignored. Side effects include, but are not limited to, heart palpitations, agitation, shortness of breath, irregular heartbeat, sweating, nausea, headaches, and psychic/metabolic disorders. It is a powerful hormone, and one that could potentially alter the normal functioning of the body if misused. When administering Liothyronine Sodium (T3), one must remember to increase the dosage slowly. Generally one 25 mcg tablet is taken on the first day, and the dosage is thereafter increased by one tablet every three of four days for a maximum dosage of 100 mcg. This will help the body adjust to the increased thyroid hormone, hopefully avoiding any sudden “shock” to the system. The daily dose is also to be split evenly throughout the day, in an effort to keep blood levels steadier. Women are more sensitive to the side effects of Liothyronine Sodium (T3) than men, and usually opt to take no more than 50 mcg daily.
