  • Introduction to the 63 IQ Studies

    Overview As of November 2019, a total of 71 studies have investigated the relationship between fluoride and human intelligence, and over 60 studies have investigated the relationship fluoride and learning/memory in animals. Of these investigations, 63 studies have found that elevated fluoride exposure is associated with reduced IQ in humans, while over 60 animal studies […]

  • Fluoride Lowers IQ in Kids, New Study Shows

    A review of some two dozen studies by Harvard University researchers published this month in a peer-reviewed federal journal suggests that fluoride added into water supplies “significantly” decreases the IQ of children, leading to renewed calls by activists to end the controversial practice of fluoridation. Most public water supplies in the United States still have […]

  • Harvard Study Finds Fluoride Lowers IQ

    Harvard University researchers’ review of fluoride/brain studies concludes “our results support the possibility of adverse effects of fluoride exposures on children’s neurodevelopment.” It was published online July 20 in Environmental Health Perspectives, a US National Institute of Environmental Health Sciences’ journal (1), reports the NYS Coalition Opposed to Fluoridation, Inc. (NYSCOF) “The children in high […]

  • 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 […]

  • 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 […]

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

  • Fluoride Opposition: Scientific, Respectable & Growing

    Since the Fluoride Action Network (FAN) first issued a statement in August 2007 calling for an end to fluoridation, over 1300 additional professionals signed on as even more evidence emerges to condemn fluoridation. Also, 53 cities rejected fluoridation on election day. Now over 1,950 professionals urge Congress to stop water fluoridation until Congressional hearings are […]

  • Fluoride & IQ: The 64 Studies

    As of December 2019, a total of 72 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 64 studies have found that elevated fluoride exposure is associated with reduced IQ in humans, while over 60 animal studies have found that fluoride exposure impairs the learning and/or memory capacity of animals. The […]

  • Dopamine receptor D2 gene polymorphism, urine fluoride, and intelligence impairment of children in China: A school-based cross-sectional study.

    EXCERPTS … In China, endemic fluorosis is classified into drinking-water type, drinking-tea type, and coal-burning type. Humans are exposed to high fluoride mainly through drinking groundwater with high fluoride content (Barbier et al., 2010). When fluorine is absorbed, it enters the blood and distributes throughout the body, mainly in bones and teeth (Barbier et al., […]

  • Harvard scientists: Data on fluoride, IQ not applicable in U.S.

    Harvard University scientists say that Wichita voters shouldn’t depend on a research study they compiled to decide whether to put fluoride in the city’s drinking water to fight tooth decay. While the studies the Harvard team reviewed did indicate that very high levels of fluoride could be linked to lower IQs among schoolchildren, the data […]
