Neurotoxicity: Fluoride & IQ

As of November 2021, a total of 81 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 73 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 Mother-Offspring Fluoride Studies

There are now 9 mother-offspring fluoride studies. The latest study examined associations between maternal fluoride intake from food and beverages during pregnancy and offspring neurodevelopment. Eight of the studies revealed that in fluoridated communities the fetus and the formula-fed infant are the most vulnerable to fluoride’s neurotoxicity. Read more about fluoride’s neurotoxicity in utero here.

National Toxicology Program

The National Toxicology Program (NTP) is the research arm of U.S. regulatory agencies. The NTP is part of the National Institute of Environmental Health Sciences (NIEHS), an agency that has been able to perform good science amidst a battlefield of conflicting inter-agency interests. However, time will tell whether the good reputation of the NIEHS and NTP will survive the battle on fluoride’s neurotoxicity. The NIEHS comes under the umbrella of the National Institutes of Health (NIH). NTP has spent four years and millions of dollars to produce two draft systematic reviews on fluoride’s neurotoxicity. Read more about the NTP’s work on fluoride here.

Your State’s Fluoridation Facts

The FAN State Fluoride Database is designed to enable you to access key fluoride-related information relevant to your state and community. With this database you can read the latest fluoride news from your state; find out if your town is fluoridated, see if any communities have recently rejected fluoridation, learn if your state has a law that mandates fluoridation, and other fluoride-related information. Read more about what  your state is doing with fluoridation.
