Changes in thyroid binding proteins may affect thyroid test results without true dysfunction. Total T3 test measures overall levels of T3 in a blood sample. This includes protein bound hormones and free hormones. Dosing is always guided by candy96.fun your symptoms, not just the numbers. We retest every few months while you are adjusting to make sure your levels are where they need to be — and that how you feel matches what the labs show. Medical-grade supplements from Taylor MD Formulations are part of our thyroid support protocols. Progesterone also directly supports thyroid receptor sensitivity. We may use adaptogens, adrenal glandulars, or other targeted support alongside thyroid therapy. For patients who have been on T4-only medications with poor results, adding T3 is often the missing piece. At the end of the day, estrogen dose equivalents are best thought of as reference points, not absolutes. There have been some questions about progestogen doses, so I will work on a post. The biggest difference is North America uses a different transdermal to oral estradiol conversion than the Australian and British Menopause Societies. Clinical laboratory units online conversion from conventional or traditional units to Si units. Management of menopausal symptoms. If you’re switching formulations, think of it more as an informed starting place and less as a precise dosing recommendation—then adjust as needed in shared decision making with your health care professional. And if enough people want me to put together a similar chart for low or higher dose regimens, let me know. The reality is that it takes combing through multiple studies, looking at the relief of symptoms and the pharmacokinetics (that is if they were done), and creating a rather complex document to see how they all compare. Everyone seems to be in agreement (or close enough) for the transdermal products and Premarin (oral conjugated equine estrogens). Free hormone testing helps clarify true thyroid levels. Most hormones circulating in the blood are protein bound. Total T4 and Total T3 reflect all hormones circulating in the blood. The total T4 test measures the bound and free hormone circulating in the blood. Slightly higher doses are required for injectable estradiol esters relative to endogenous production amounts since they contain less estradiol by weight due to the ester components (Table). C Much lower doses of transdermal estradiol can be used in the case of genital application relative to conventional skin sites (potentially e.g. 5-fold lower doses for similar estradiol levels) (Aly., 2019). Low Free T3, high Reverse T3, or elevated antibodies can all produce hypothyroid symptoms with a completely normal TSH. That is part of why hypothyroidism gets missed or misdiagnosed for years. One of the most telling signs we use is basal body temperature. It does not tell you how much T3 your cells are actually getting, whether your body is converting T4 to T3 properly, or whether reverse T3 is blocking the whole process. If it comes back in range, they tell you your thyroid is fine and move on. Hypothyroidism Atlanta at Taylor Medical Group goes beyond the standard TSH test. Why do some people have normal thyroid labs yet still feel exhausted, foggy, or gain weight? One of the most common questions where hormones are concerned is what dose of one form is equivalent to another. Hence, the high to very high doses are indicated for estradiol monotherapy (i.e., estradiol alone without an antiandrogen). On average, the high dose will suppress testosterone levels by about 90%, to around 50 ng/dL (Wiki; Aly, 2018). We run the full thyroid panel along with cortisol, sex hormones, nutrients, and other relevant markers depending on your picture. If elevated cortisol is blocking T3 conversion, addressing adrenal function is part of the thyroid plan — not a separate issue. Poor gut health — dysbiosis, leaky gut, inflammation — reduces that conversion and impairs absorption of thyroid medication. The result is lower Free T3 and Free T4 even if your total thyroid levels look fine.
