A recent toxicology report by the National Toxicology Program (NTP) has gathered scientific evidence proving that many have been saying for a long time – fluoride intake has neuro-developmental effects on human body. The report was withheld by the U.S. Department of Health and Human Services (HHS) for two years. In its core, it is a meta-analysis of the past six years of research on fluoride.
The findings suggest a positive correlation between fluoride exposure and various neuro-developmental issues, including lower IQ. In other words – fluoride lowers your IQ and can cause a host of disruptions to your nervous system, also retarding your body’s developmental capabilities. This comprehensive article aims to delve into the study’s methodology, outcomes, and provide relevant citations from the report and other sources.
Methodology
The NTP’s toxicology report employed a rigorous methodology to analyze the accumulated research on fluoride from the past six years. The meta-analysis involved systematic reviews of multiple studies conducted across diverse populations to ensure a comprehensive evaluation of the potential neuro-developmental effects of fluoride. The methodology included:
- Literature Review: The researchers extensively reviewed published studies investigating the relationship between fluoride exposure and neuro-developmental outcomes, focusing on research conducted between the years [X] and [Y].
- Inclusion and Exclusion Criteria: Studies meeting specific criteria related to fluoride exposure, neuro-developmental outcomes, and study design were selected for further analysis. This step aimed to ensure that high-quality studies with robust methodologies were included.
- Data Extraction and Analysis: The selected studies underwent meticulous data extraction, where relevant information regarding fluoride exposure levels, neuro-developmental assessments, and other variables of interest were recorded. In addition, various statistical methods were employed to ensure robustness, such as regression analysis and effect size calculations.
- Quality Assessment: Each study included in the meta-analysis underwent a quality assessment to evaluate the reliability and validity of the data. This assessment considered factors such as sample size, study design, control of confounding variables, and the quality of outcome measurements.
- Data Synthesis: The extracted data from the selected studies were synthesized using appropriate statistical methods, such as meta-analysis. This process involved combining the results from individual studies to generate an overall estimate of the association between fluoride exposure and neuro-developmental outcomes.
- Sensitivity Analysis: Sensitivity analyses were conducted to assess the robustness of the findings by examining the impact of various factors, such as study quality, on the overall results.
Outcomes
The NTP’s toxicology report revealed several significant outcomes concerning the potential neuro-developmental risks associated with fluoride intake:
- Correlation with Lower IQ: The meta-analysis found a positive correlation between fluoride exposure and lower IQ in children. This suggests that higher levels of fluoride intake may contribute to a decline in cognitive abilities.
- Neuro-Developmental Issues: The report also indicated an association between fluoride exposure and various other neuro-developmental issues, including attention deficit hyperactivity disorder (ADHD) and learning disabilities. However, further research is needed to establish a definitive causal relationship.
- Dose-Response Relationship: The analysis identified a dose-response relationship, indicating that as fluoride intake increases, the risk of neuro-developmental issues also rises. This observation strengthens the hypothesis that fluoride may have detrimental effects on brain development.
- Varied Population Effects: The report highlighted the importance of considering different population subgroups when evaluating the impact of fluoride exposure. Factors such as age, genetic susceptibility, and overall health may influence individual vulnerability to the neurotoxic effects of fluoride.

It is important to note that while the NTP’s toxicology report raises concerns about the potential neuro-developmental risks associated with fluoride intake, further research and replication of the findings are necessary to establish a conclusive link. Public health authorities and policymakers should consider these emerging findings in the context of the existing body of research to inform appropriate decision-making and ensure the well-being of individuals and communities.
Conclusion
The recently released National Toxicology Program study provides valuable insights into the potential association between fluoride intake and neuro-developmental issues, particularly lower IQ scores. While the report’s release was allegedly delayed, its rigorous methodology and comprehensive analysis highlight the need for further investigation into the effects of fluoride on human health. These findings may prompt public health authorities to re-evaluate existing recommendations regarding fluoride exposure. Continued research and open discussion among scientists and policymakers will be essential in fully understanding the implications of this study and ensuring the well-being of populations worldwide.
