For those who are wondering why Thyroid Rescue 911 Review they have all the symptoms of hypothyroidism (low thyroid hormone) but always test in the ‘normal’ range, take heart-you are not crazy and there may indeed be something not quite right with your thyroid. First of all, the thyroid tests used by laboratories are notoriously inaccurate, being ‘off by three standard deviations’ (pretty much useless except in certain cases).
Adding to the confusion is the difference between T3 and rT3 (Triiodothyronine and reverse Triiodothyronine). T3 is the active form of thyroid hormone in the blood and is converted from T4, which is produced in much larger amounts than T3. Synthetic T4 is what is provided in pharmaceutical medicines, which works fine as long as everything else in the pathway is working.
The tricky part comes when T3 is no longer being converted from T4, instead being converted into rT3 (reverse triiodothyronine). Think of it like this: reverse forms of the natural substances that we need are chemical mirror images. They are exactly flipped and don’t work the same way. Because the chemical ‘lock’ is oriented either right or left and the reversed form is oriented in the opposite direction, the reversed ‘key’ just doesn’t fit.
For instance, our bodies use D-glucose (dextrose) with is a right-rotatory molecule. L-glucose-a left-rotatory molecule–cannot be metabolized. It can taste the same, look the same, often have the same properties (dissolving in water the same, burning the same, etc) but it still is not D-glucose. So since the tissues of the body need T3, and rT3 won’t fit the lock, the symptoms of hypothyroidism occur.The symptoms of hypothyroidism have been treated by many physicians as indicative of hypothyroidism despite ‘normal’ lab tests. Those symptoms include the following.
