F.A.N. Discussion Forum > fluoride substituted thyroxine

AS fluorine can displace iodine in compounds due to its greater reactivity, the possibility is that thyroxine (T4) and tri-iodothyronine (T3) can have iodine substituted by fluorine. Has anyone a link that might shed light on this problem.
Does a fluoro-di-iodothyronine have less activity than the parent molecule, or none at all?
Paediatric hypothyroidism is linked to precocious puberty, How strongly? Is fluorine a contributor to this significant trend.
ADHD has, as one of its possible comorbidities,resistance to thyroid hormone. Any links to thyroid activity in gestation and ADHD? The purported (and probably very real) increase in Autistic Spectrum Disorders (of which ADHD is one) might be telling.
Thanks

Presumably you have familiarized yourself with the info and links at the FAN Fluoride and Thyroid page: http://www.fluoridealert.org/health/thyroid/.
The first two bulletins sent out by PFPC articulated Andreas Schuld's findings on the influence of fluoride on the thyroid. They are now available through membership at http://poisonfluoride.com/pfpc/html/newsletters.html.
And lastly, Russell Dobkins, B.S, C.W.K., expounds on fluoride/thyroid effects and the possible ADHD/cerebral hypothyroid connection in his posting at: http://health.groups.yahoo.com/group/FluoridePoisoning/message/6755. Elsewhere he states he has written an article entitled "Monitoring and Correcting Maternal Levels of Thyroid Hormones to Optimize Neurological Development of the Fetal Brain".
