US government analysis finds moderate confidence in the connection between elevated fluoride and reduced cognitive scores in kids.
- The report is the first federal acknowledgment of a potential neurological risk from high fluoride levels.
- Studies reviewed indicate children exposed to over 1.5 mg/L of fluoride have consistently lower IQs.
- Approximately 1.9 million Americans are on water systems with naturally high fluoride levels.
- The American Dental Association is reviewing the findings, which counter previous endorsements of water fluoridation.
