FDA Recommends Putting Limits to the Amount of Fluoride Added to Bottled Water

May 20, 2015

The US Food and Drug Administration (FDA) released a recommendation to set limits to the amount of fluoride added to bottled water. The recommendation comes from the US Public Health Service (PHS) and specifies that bottled water manufacturers, distributors and importers should limit the amount of fluoride they add to bottled water to no more than 0.7 milligrams per liter (mg/L). The recommendation also states that this is the optimal fluoride level that provides the best balance of dental protection while limiting the risk of dental fluorosis.

The new recommendation replaces the old limit of 0.7-1.2 mg/L for fluoride.
