  • 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 […]

  • Neurotoxic effects of fluoride

  • Is fluoride in private wells causing an IQ decline?

    Excess fluoride, which may damage both brain and bone, is leaching out of granite and into Maine’s drinking water—and potentially other New England states … Like the majority of the state, many of Dedham’s denizens rely on private wells for the water they drink, bathe in and perhaps use to make infant milk formula. … […]

  • 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 […]

  • Introduction to the 69 IQ Studies

    Overview As of June 2021, a total of 77 studies have investigated the relationship between fluoride and human intelligence, and over 60 studies have investigated the relationship between fluoride and learning/memory in animals. Of these investigations, 69 studies have found that elevated fluoride exposure is associated with reduced IQ in humans, while over 60 animal […]

  • New studies reveal that drinking certain kinds of tea poses dangerous health risks

    Fortunately, there are ways to minimize them Next to water, tea is the most popular beverage in the world, which is generally a good thing: Besides being tasty and soothing—or energizing, depending on what you’re going for—a seemingly endless body of research has linked it with a huge number of mental and physical health benefits. […]

  • 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 […]

  • Michael Connett on Fluoride & IQ Studies

    Michael Connett of the Fluoride Action Network gives a presentation on the mounting evidence that fluoride reduces IQ in children. The IQ studies are just the “tip of the iceberg” when these animal and non-IQ studies are considered. Research continues to support the idea that fluoride is a neurotoxin. Video from the 2014 Fluoride Action […]

  • Fluoride still used in most Oklahoma cities despite reports of brain damage, low IQ in children

    OKLAHOMA CITY – Most Oklahoma municipalities continue to inject fluoride into public drinking water despite global reports that the mineral can lead to brain damage and a lower IQ in children. Some cities across the nation have engaged in controversial debates over fluoride and whether its benefits outweigh the risks. In other parts of the […]
