Latest Fluoride Research

January 2020

A study published on November 21, 2019 found a significant decrease in the IQ of children who had been fed infant formula reconstituted with fluoridated tap water, compared to formula-fed children living in un-fluoridated areas. The study, by a research team based at York University, followed a large cohort of Canadian mother-child pairs through age 3-4 years (Till et al. 2020). This study supports earlier research demonstrating neurological harm to children whose mothers were exposed to fluoride during pregnancy (Bashash et al. 2017).

We recommend the use of Distilled or Reverse Osmosis (R.O.) water for mixing infant formula. Using either of these waters will result in formula with the same low levels of fluoride found naturally in breast milk. We aim to raise awareness about this important issue and as a commitment to the health of our customers, we are providing free R.O. Water to new mothers who use infant formula. Please contact our office for more information about other sources of fluoride exposure.
