The thyroid drug Synthroid (levothyroxine sodium), as the name implies, is anything but natural. It is not bio-equivalent to the natural hormone thyroxine, but is instead a synthetic, hormone-like substance with very different properties.
In conventional medical treatment for hypothyroidism, once blood variables fall into a range deemed "normal" thanks to the introduction of synthetic chemicals, the "treatment" is deemed a success. Unfortunately, the quality of life of the patient may actually worsen as the synthetic chemicals compete with the remaining natural hormones still being produced by their thyroid.
