I have been involved in a research study assessing transdermal absorption of fluoride from fluoridated water. The current results indicate that skin absorption fromthe bathing water is quite significant. This shows that people who want to avoid fluoride in drinking water by buying bottled water containing no significant concentration of fluoride cannot avoid fluoride unless they stop washing and bathing themselves.

This research is being finalized for a publication in a peer refereed scientific journal.


Dear Professor, would welcome any more you can offer on this subject pre-publication. Maybe you could send us a summary or a first draft.




Question: It would seem to me that a person who has to bathe in fluoridated water would be better off bathing instead of showing because he would inhale less fluoride and chlorine in water droplets.


Is there any calcium or magnesium lotion which one could apply after showering which would supply the fluoride the positive ions if seeks.


I have been trying magnesium oil from Ancient Minerals after doing a quick bath in one inch of water. It stings. I am not sure it is safe or helpful.

    From James Robert Deal: Whether the fluoride is naturally occurring calcium fluoride, sodium fluoride or fluorosilicic acid, fluoride forms some hydrogen fluoride. There is more HF formed if the pH is more acidic, and stomach pH is highly acidic. There is less HF formed at neutral pH in bath water or on the skin, however, the amount is not zero. When you wash your clothes in fluoridated water, the fluoride remains in your clothing, and as you perspire, you will have fluoride against your skin. Some of it will be HF, and it will pass through your skin.

    Was this study published? If so what is the name of journal and title of article?

    It is disturbing that Fluoride has been added to water supplies for over 60 years and yet I have been unable to locate any studies by the EPA regarding trans dermal absorption!

    One source by DHSS Delaware reported Hydrogen Fluoride absorbs through the skin at alarming levels. This is not the same form of Fluoride used by majority of municipalities. However, logic dictates skin absorption levels would be similar with variations of the same substance.

    It has been 5 years since this was posted. Has the study results been published? If so what is the journal name and article title so I may read the results?

    The EPA has yet to publish any studies on this subject that I could find. Hydrogen Fluoride was reported to absorb via skin at alarming levels but no information regarding fluorsilic Acid (63% municipality use), Sodium Fluorisicate (28% use), or Sodium Fluoride (9% use). It seems like information is missing on purpose!

    Fluoride has been added to public water supplies for over 60 years. It is disturbing to find find such a lack of information. I am not a science major but logic would dictate the different forms of Fluoride would have a similar reaction for trans dermal absorption.

    When assessing transdermal absorption of fluoride from fluoridated water, I am under the assumption that it would have to performed on living , breathing people.

    Could the absorption data be used to diagnose chronic fluoride intoxication, espically in suceptable populations?

    A protocall of tests in combination with transdermal absorption might include kidney function, thyroid function and even brain function.

    Could PET/CT scanning using F18 in bath/shower water be used to show , in virtually real time, how the fluoride is taken up and the target organs and tissues revealed?
