Fluoride exposure appears to slightly decrease IQ scores in children, a new federal meta-analysis has concluded -- but not at the low levels recommended for U.S. drinking water.

A rigorous nine-year research review looking at the relationship between fluoride and intelligence in children concludes that as fluoride levels rise, IQ drops.

A new report linking fluoridated drinking water to lower IQ scores in children is sure to ratchet up the debate over a practice that's considered one of the greatest public health achievements of the 20th century.

(CNN) – Being exposed to high levels of fluoride could impact intelligence. According to a new government survey, fluoride levels in children’s urine were measured. They reported a drop in IQ scores as fluoride levels rose. The study was published in the medical journal JAMA Pediatrics Monday, but the research was released in late 2024.

A new study commissioned by the National Institute of Environmental Health Sciences looked at the effect that high fluoride consumption can have on childre

A controversial new study out Monday in a US medical journal could reignite debate over fluoride's safety in water, linking higher exposure levels to lower IQ in children.

"There is scientific consensus that the urinary sample collection approaches used in almost all included studies (ie, spot urinary fluoride or a few 24-hour samples, many not adju

A report out today concludes there is a statistically significant correlation between higher levels of fluoride and lower IQ levels in children. The analysis looked at previous studies conducted overseas.

An analysis of more than 70 studies on fluoride and IQ levels concluded there was a relationship between higher levels of the common water additive and lower IQ levels in children, though a large percentage of the studies were noted as having a “high risk of bias.
