US Government Report Says That Flouride At Twice The Recommended Limit Is Linked To Lower IQ In Kids.
A recent federal report has reignited debate over fluoride in drinking water, revealing potential risks associated with high fluoride levels. The study, conducted by the National Toxicology Program (NTP), suggests that fluoride concentrations above the recommended limits might be linked to lower IQ levels in children.
The 324-page report is the first from a federal agency to find a connection between elevated fluoride exposure and reduced cognitive function. Although the report does not quantify the exact IQ loss at various fluoride levels, some studies included in the review indicated a drop of 2 to 5 IQ points in children with higher fluoride exposure.
Since 2015, U.S. health officials have recommended a fluoride concentration of 0.7 milligrams per liter (mg/L) in drinking water. This is a reduction from the previous upper limit of 1.2 mg/L, in response to growing concerns about dental fluorosis—a condition that causes discoloration of teeth. The World Health Organization sets a safe upper limit of 1.5 mg/L for fluoride in drinking water.
The report highlights that approximately 0.6% of the U.S. population—around 1.9 million people—use water systems with naturally occurring fluoride levels of 1.5 mg/L or higher. This raises questions about how to protect those affected and whether current standards are sufficient.
Interestingly, the report did not address the effects of fluoride at lower levels or its impact on adults. The American Dental Association, which supports water fluoridation for its dental benefits, had criticized earlier drafts of this analysis but has yet to provide a formal response to the final report.
Fluoride, a mineral found naturally in water and soil, became a focal point in dental health discussions in the mid-20th century after studies showed that higher fluoride levels could reduce tooth decay. Grand Rapids, Michigan, became the first U.S. city to fluoridate its water in 1945, and by 1950, the practice was endorsed nationally.
The Environmental Protection Agency (EPA) has maintained a maximum allowable fluoride concentration of 4 mg/L in drinking water to prevent skeletal fluorosis—a disorder causing bone stiffness and pain. However, growing evidence suggests that high fluoride levels may affect brain development, particularly in developing fetuses and young children who consume water used for baby formula.
Rick Woychik, director of the National Toxicology Program, emphasized the importance of accurate science in addressing fluoride's health impacts. The report has reignited discussions about whether further regulations or public health advisories are needed.
Ashley Malin, a researcher from the University of Florida, suggests that reducing fluoride intake, particularly among pregnant women and from sources like certain teas, might be prudent. She also proposed considering policies for fluoride content labeling on beverages.
As the debate continues, the findings from this report could lead to further scrutiny of fluoride use in public health and potentially influence future guidelines and policies.

Call your water companies and tell em you don't want that flouride in your water supply... naturally occuring isnt the same thing. God Speed Viewers.
