The thyroid, a small gland in the neck, controls a wide variety of processes in the human body. When the body isn’t producing enough of the thyroid hormones, an individual is likely to experience a range of thyroid-related symptoms. For example, a person may suffer from one or many of the following: depression, poor memory, brittle hair, increased cholesterol, poor tolerance of cold, constipation, lack of energy, weight gain, swelling or puffiness of the face, hoarseness of voice, and an increased risk of heart problems. Adequate levels of thyroid hormones increase blood flow, heart rate and body heat production as well as raising your level of HDL (good cholesterol) and boosting the immune system.
It is strongly recommended that any thyroid therapy undertaken to counter thyroid-related symptoms should utilize bio-identical T3 and T4 (the principal thyroid hormones) rather than synthetic T3 and T4. The former is well tolerated by the human body whereas the latter frequently is both less efficacious and may give rise to undesirable side-effects.
