Mary Byrne and Kane Titchener of Fluoride Free NZ present the case against fluoridation including the latest neurotoxicity science from the National Toxicology Program. The NTP is in the final stages of publishing a 6 year review of the neuroscience research. The NTP found that 52 of 55, 95% consistency, showed a lowering of IQ. 18 of 19 High quality studies showed a lowering of IQ. There is no safe threshold of fluoride in water and the average IQ loss is 3 - 5 IQ points on average.
