Pilot study underway to confirm superior method of diagnosing fluoride levels in the body

Dr. Phyllis Mullenix, FTRC Research Program Director, in conjunction with FTRC, has been in charge of this study.  So far, results are consistent and excellent.  This study should lead the way toward easy and accurate diagnosing of fluoride poisoning.

Pilot project plan to study fluoride content in supplements and other common products, as well as other avenues of possible fluoride exposure

FTRC plans to run a pilot study a soon as feasible, to determine the fluoride content in various food supplements and other products, as well as places that people commonly can be exposed to fluoride, such as swimming pools. The results of this research will be used to inform fluoride sensitive people who must always be vigilant about possible fluoride exposure. We will make results public as soon as they are determined.

International Journal of Occupational and Environmental Health, Vol.20/Issue 2, April/June 2014: 404-414. For access to this paper:


Fluoride additives contain metal contaminants that must be diluted to meet drinking water regulations. However, each raw additive batch supplied to water facilities does not come labeled with concentrations per contaminant. This omission distorts exposure profiles and the risks associated with accidents and routine use.

This study provides an independent determination of the metal content of raw fluoride products.

Metal concentrations were analyzed in three hydrofluorosilicic acid (HFS) and four sodium fluoride (NaF) samples using inductively coupled plasma-atomic emission spectrometry. Arsenic levels were confirmed using graphite furnace atomic absorption analysis.

Results show that metal content varies with batch, and all HFS samples contained arsenic (4·9–56·0 ppm) or arsenic in addition to lead (10·3 ppm). Two NaF samples contained barium (13·3–18·0 ppm) instead. All HFS (212–415 ppm) and NaF (3312–3630 ppm) additives contained a surprising amount of aluminum.

Such contaminant content creates a regulatory blind spot that jeopardizes any safe use of fluoride additives.

Forthcoming FTRC book on fluoride poisoning

The Fluoride Illness Handbook: A Guide to Identification and Treatment is meant to help health professionals recognize fluoride-poisoning symptoms, and suggest ways for them to treat the condition. We expect that our book will help to dramatically change the landscape in terms of acceptance and understanding of fluoride’s extremely toxic effects. Check this space for more detailed summary when book has been published.

Second Look/FTRC is proud to announce the first peer-reviewed publication we have helped to sponsor - Dr. Phyllis Mullenix's article: Fluoride Poisoning: A Puzzle with Hidden Pieces. International Journal of Occupational and Environmental Health, Vol.11/No.4, Oct/Dec 2005: 404-414. For the full paper:


Key industry data regarding harm from chronically inhaled fluoride have been unavailable publicly for decades. Recent unveiling of unpublished reports reveals three examples of data mishandling that disguised the need for more stringent occupational standards for particulate and gaseous fluorides and fluorine. Injury reports from workers handling chemicals show that unjustifiable reductions of injury and disability numbers in the process of publication shifted concern from respiratory to mineralized tissue damage. Selective editing and data omissions allowed bias that fluoride reduces caries without detrimental effects. Finally, industry's failure to publish an important industry-funded laboratory study buried knowledge of low thresholds for fluoride-induced lung disease. Data from that study are presented to clarify the dose- and duration-dependent changes caused by chronic inhalation of calcium fluoride. Key words: fluorides; fluorine; chronic inhalation; respiratory injury; occupational standard.
