  • Fluoride’s Brain Damage Studies Mounting

    Studies showing fluoride can lower IQ are just the tip of the iceberg in fluoride/neurotoxicity research, according to evidence presented by attorney Michael Connett, Fluoride Action Network’s (FAN) Special Projects Director at the 5th Annual FAN Conference on September 6, 2014. Public health officials never considered brain effects before instigating fluoride’s addition to water supplies […]

  • A Benchmark Dose Analysis for Maternal Pregnancy Urine-Fluoride and IQ in Children.

    Discussion … The increased precision using the average maternal U-F concentration as an indicator of prenatal fluoride exposure results in stronger statistical evidence of fluoride-associated deficits, compared with using cross-sectional or retrospective studies. Still, the amount of fluoride that reaches the brain during early brain development is unknown, and even the maternal U-F concentration measurements […]

  • Studies show fluoridated tap water can have negative effect on health

    Most toothpaste boxes have a portion that reads drug facts on the back. Underneath that it states sodium fluoride. Elsewhere on the box it states if you swallow more than used for brushing teeth, get medical help or contact Poison Control right away. According to the South Central Connecticut Regional Water Authority, New Haven has […]

  • Dunedin fluoride-IQ study finds no ill-effect

    A planned Dunedin study into whether fluoridated water reduces IQ has been shelved. However, another University of Otago study looking at the same controversial question has been completed, its findings accepted for publication later this year in a prominent American public health journal. Co-authored by public health dentistry specialist Dr Jonathan Broadbent, it found no […]

  • Fluoride & IQ: 76 Studies

    • As of July 18, 2022, a total of 85 human studies have investigated the relationship between fluoride and human intelligence. • Of these investigations, 76 studies have reported that elevated fluoride exposure is associated with reduced IQ in humans. • The studies which reported an association of reduced IQ with exposure to fluoride, are […]

  • Study claiming fluoride does not lower IQ is flawed

    A recent New Zealand study published in the American Journal of Public Health, which claims to exonerate a link between fluoride and lowered IQ, is scientifically flawed and reveals blatant examiner bias, says the Fluoride Action Network (FAN). The study’s co-author, pro-fluoridation activist and dentist Jonathan Broadbent, claimed: “Our findings will hopefully help to put […]

  • FAN campaign targets pregnancy and water fluoridation

    The Fluoride Action Network (FAN) launched its “Moms2B Avoid Fluoride” campaign to alert pregnant women that consuming fluoride, especially from fluoridated water, can potentially harm the developing brain of their unborn child, according to newly published research. FAN pointed to to two “mother-child” studies in 2017 and 2018 on the cognitive effect of fluoride on […]

  • Chemicals like fluoride in toothpaste may be eroding child IQs: disputed study

    Paris:  Two public health experts warned on Saturday about the stunting effects that a wide array of industrial chemicals, including toothpaste ingredient fluoride, may be having on child brain development, in a report some called alarmist. The pair, Philippe Grandjean of the Harvard School of Public Health and Philip Landrigan from New York’s Icahn School […]

  • 64 studies have linked fluoride with reduced IQ in children.

  • Fluoride Studies funded by the U.S. Government

    Overview The human studies funded by U.S. government agencies, particularly Bashash 2017, Green 2019 and Till 2020, reveal that in fluoridated communities the fetus and the formula-fed infant are the most vulnerable to fluoride’s neurotoxicity. Certain high levels of fluoride in the pregnant women’s urine were found to significantly impact the IQ, or neurodevelopment, of […]
