When I looked at her Reverse T3 – the thyroid hormone that does the opposite (the reverse) of T3 – was at the 100th percentile – right at the top of the reference range. When Reverse T3 becomes elevated, the metabolism of the body shuts down. It is more of an “inactivating” hormone, which interferes with T3 function if the Reverse T3 gets too high.
Her anti-thyroid antibodies (anti-thyroglobulin and anti-thyroid peroxidase) were all low throughout the testing. She did not have autoimmune thyroid disease. Her problem was too much Reverse T3.
In the first month after starting ThyroMend™ her Reverse T3 dropped to the 90th percentile, while her free T3 increased to the 38th percentile and free T4 increased to the 40th percentile. In the third month of taking ThyroMend™ her Reverse T3 dropped to the 50th percentile – close to the middle of the reference range.
As you can tell, I use percentiles to analyze hormone levels. Looking at levels as being “in range” does not give the full picture. I also compare hormones with each other. A good way to get the big picture is to compare the “active” hormones with the “inactivating” hormone. That “Thyroid Hormone Ratio” would be a ratio of free T3% + fee T4% / RT3%. The Thyroid Hormone Ratio is the definitive proof of improved thyroid hormone function. A common mistake is to look at just T4 and T3 and not pay attention to the Reverse T3.
Her ratio went from 55% up to 129% - demonstrating that her metabolism had increased. As a result, she started to lose weight, had more energy and her thinking became more clear – less “brain fog”. The attached image shows how the Reverse T3 (red line) dropped, while the Thyroid Hormone Ratio (green line) rises significantly.
I advise that all of the thyroid hormones be tested as I mention on the page about Thyroid Lab Tests at ThyroMend.com.
