  • Iodine Status Modifies the Association between Fluoride Exposure in Pregnancy and Preschool Boys’ Intelligence

    In animal studies, the combination of in utero fluoride exposure and low iodine has greater negative effects on offspring learning and memory than either alone, but this has not been studied in children. We evaluated whether the maternal urinary iodine concentration (MUIC) modifies the association between maternal urinary fluoride (MUF)

  • Thyroid function, intelligence, and low-moderate fluoride exposure among Chinese school-age children.

    Highlights Low-moderate fluoride was related to alterations in childhood thyroid function. Fluoride exposure was associated with a decrease in children’s intelligence. TT3, FT3 were positively related to the odds of developing high normal intelligence. TSH may modify the association of fluoride with children’s intelligence. Background: Thyroid hormones (THs) are critical for

  • Studies of relationships between the polymorphism of COMT gene and plasma proteomic profiling and children’s intelligence in high fluoride areas

    Part I – Effect of high F drinking water on children’s IQ Objective: To investigate the relationships among the children’s serum F, urine F, thyroid hormone levels and children’s IQ in the high fluoride areas. Methods: We collected the samples of the drinking water, urine and blood and measured the F concentrations,

  • Prenatal Fluoride Exposure and Cognitive Outcomes in Children at 4 and 6–12 Years of Age in Mexico

    Background: Some evidence suggests that fluoride may be neurotoxic to children. Few of the epidemiologic studies have been longitudinal, had individual measures of fluoride exposure, addressed the impact of prenatal exposures or involved more than 100 participants. OBJECTIVE: Our aim was to estimate the association of prenatal exposure to fluoride with

    Note: See the Updated list of fluoride IQ studies at https://fluoridealert.org/researchers/fluoride-iq-studies/the-fluoride-iq-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

  • Fluoride, Water Hardness, and Endemic Goitre

    Variations in goitre prevalence were found to correlate closely with the fluoride content (p=0-74; P<0-01) and with the hardness (p=0.77; P<0-01) of the water in each village. The effects of fluoride and water hardness seem to be independent.

  • The Relationship Between Fluoride Exposure & Goitre in South Africa

    As a general rule simple goitre, irrespective of the cause, can be very, or fairly, satisfactorily combated by an adequate increase in man's daily iodine intake, except when the enlargement of the gland is due to the ingestion of excessive amounts of fluorine. The only correct solution to fluorine-induced endemic goitre is the removal of this element from the drinking water.

  • Fluoride Affects Learning & Memory in Animals

    An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out

  • Nutrient Deficiencies Enhance Fluoride Toxicity

    It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,
