Please answer! what prevents halogen substitution in thyroid hormones?

Please answer! what prevents halogen substitution in thyroid hormones?

Thyroid and iodine: I found this question on some blogs; sounds like the kind of myth that springs up from a little knowledge and an axe to grind. The thyroid traps iodine to make t3 (liothyronine) and t4. It does not trap Fluoride or bromide. The amount of iodine in the diet is far more than the other halogens. I wonder if this comes from the people who continue to believe (against all evidence) that fluoridated water is bad. ...Read more

Sedative : Xanax (alprazolam) is a sedative and should calm you. Some people enjoy the way it makes them feel calm and a bit out of it, and begin abusing it. It is an addictive medication and should only be used as directed. Thyroid medication does not make you high.
