At the Arkansas Department of Health quarterly board meeting on July 23, 2015, Sandra Young, M.D. spoke about fluoride lowering I.Q. as well as causing other chronic health problems. This article is written from a doctor’s standpoint and will address those topics in more detail; it should especially capture the attention of our medical and scientific audience.
Michael Connett, son of Paul Connett, PhD-author of “The Case Against Fluoride”, has recently given an excellent talk reviewing results of 48 studies on the effects of fluoride on the brain. (We highly recommend watching it!) Michael’s presentation was given at the 2014 Fluoride Action Network Conference and addresses the mounting evidence that fluoride reduces IQ in children. The IQ studies are just the “tip of the iceberg” when other animal and human studies are considered. Research continues to support the idea that fluoride is a neurotoxin.

“Fluoride compounds which are put in water (fluoridation), toothpaste, and supplement tablets (including some vitamins) were never tested for safety before approval. [If you can find evidence to the contrary, email it to Secure Arkansas! [email protected]] Recent independent research by scientists not associated with dental trade organizations has shown the following”:
Neurotoxic and lowers IQ
Alzheimer’s disease and dementia
Changes bone structure and strength
Causes birth defects and perinatal deaths
Impairs immune system
Causes acute adverse reactions
Causes initial stages of skeletal fluorosis
Increase lead and arsenic exposure
Fluoride causes osteoarthritis
Contributes to the development of repetitive stress injury
Causes permanent disfigurement of teeth in many children (dental fluorosis)
Inhibits key enzymes
Suppresses thyroid function (or conversely can cause hyperthyroidism if it stimulates the pituitary)
Causes large number of acute poisonings – This is why the FDA requires a poison warning on every tube of fluoride toothpaste sold in the U.S. (See picture below)
Independent experts oppose dumping fluoride into water
Banned in most of Europe and many other countries

In addition to the fluoride warnings published in the journal, a recent meta-analysis from Harvard found a correlation between fluoridated water and low IQ scores in children who grew up in the most fluoridated areas.

Another study says that fluoride impairs learning and memory, and this separate study links fluorosis with brain cell apoptosis (cell death). Other rat studies have linked brain damage with aluminum and fluoride in water.
Fluoride can also affect fetal brain development. This was well known previously but has apparently been forgotten. In the 1960s, the FDA banned the use of prenatal fluoride supplements based on its concern about possible untoward effects on the fetus. Yu Y, et al. (1996). Click here to read about neurotransmitter and receptor changes in the brains of fetuses from areas of endemic fluorosis. Chinese Journal of Endemiology 15:257-259; re-published in Fluoride 2008, 41(2):134–138 Areas of endemic fluorosis have higher levels than should be in our water supply, barring some malfunction of equipment. It is known that fluoride can cross the placenta from the mother’s blood to the developing fetus. “The passage of fluorine through the placenta of mothers with chronic fluorosis and its accumulation within the brain of the fetus impacts the developing central nervous system and stunts neuron development.” Du L. (1992). This article explains the effect of fluorine on the developing human brain. Chinese Journal of Pathology 21(4):218-20; republished in Fluoride 2008, 41(4):327–330.
Another Chinese study showed that fluoride retarded the growth and division of cells in the cerebral cortex. Han H, et al. (1989): Effects of fluorine on the human fetus. Chinese Journal of Control of Endemic Diseases 4(3):136-138, 1989; republished in Fluoride 2008, 41(4):321–326. A separate study showed that maternal exposure to fluoride resulted in damage to cell structures that was multifaceted. Cell membranes, mitochondria, rough endoplasmic reticulum, and nuclear membranes could all be damaged at the time of fluorosis. Yu Y. (2000): Effects of fluoride on the ultrastructure of glandular epithelial cells of human fetuses. Chinese Journal of Endemiology 19(2):81-83
In 2006, the National Research Council printed “Fluoride in Drinking Water: A Scientific Review of EPA’s Standards“. A summary of the Neurotoxicity and Neurobehavioral Effects can be found at this link.
The NRC’s recommendations were:
The possibility has been raised by the studies conducted in China that fluoride can lower intellectual abilities. Thus, studies of populations exposed to different concentrations of fluoride in drinking water should include measurements of reasoning ability, problem solving, IQ, and short-and long-term memory. Care should be taken to ensure that proper testing methods are used, that all sources of exposure to fluoride are assessed, and that comparison populations have similar cultures and socioeconomic status.
Studies of populations exposed to different concentrations of fluoride should be undertaken to evaluate neurochemical changes that may be associated with dementia. Consideration should be given to assessing effects from chronic exposure, effects that might be delayed or occur late-in-life, and individual susceptibility (see Chapters 2 and 3 for discussion of subpopulations that might be more susceptible to the effects of fluoride from exposure and physiological standpoints, respectively).
Additional animal studies designed to evaluate reasoning are needed. These studies must be carefully designed to measure cognitive skills beyond rote learning or the acquisition of simple associations, and test environmentally relevant doses of fluoride.
At the present time, questions about the effects of the many histological, biochemical, and molecular changes caused by fluorides cannot be related to specific alterations in behavior or to known diseases. Additional studies of the relationship of the changes in the brain as they affect the hormonal and neuropeptide status of the body are needed. Such relationships should be studied in greater detail and under different environmental conditions.
Most of the studies dealing with neural and behavioral responses have tested NaF. It is important to determine whether other forms of fluoride (e.g., silicofluorides) produce the same effects in animal models.
Neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, affect millions of children worldwide, and some diagnoses seem to be increasing in frequency. Industrial chemicals that injure the developing brain are among the known causes for this rise in prevalence. In 2006, we did a systematic review and identified five industrial chemicals as developmental neurotoxicants: lead, methylmercury, polychlorinated biphenyls, arsenic, and toluene. Since 2006, epidemiological studies have documented six additional developmental neurotoxicants — manganese, fluoride, chlorpyrifos, dichlorodiphenyltrichloroethan
Also, click here to read a paper by Varner et al in Brain Research (1998). We think you will relish reading it if you haven’t already. One of their many findings in a low-dose, long-term rat study was beta-amyloid deposits in rats exposed to either NaF or AlF3 (sodium fluoride or aluminum fluoride). These are seen in Alzheimer’s Disease.
