Fluoride is Classified as a Neurotoxin

While the Centers for Disease Control (CDC) would have us all believe that fluoride is perfectly innocuous and safe, scientists from the EPA’s National Health and Environmental Effects Research Laboratory have classified fluoride as a “chemical having substantial evidence of developmental neurotoxicity”. Consistent with the EPA’s conclusion, a continually growing body of human and animal research strongly suggests that fluoride can damage the developing brain.
Consider for example:
24 studies have now reported an association between fluoride exposure and reduced IQ in children
Three studies have reported an association between fluoride exposure and impaired neurobehavioral development
Three studies have reported damage to the brain of aborted fetuses in high fluoride areas, and
Over 100 laboratory studies have reported damage to the brain and/or cognitive function among fluoride-exposed animals.
