As of 2014, the International Bottled Water Association lists more than 20 brands of bottled water that contain fluoride. A few of the brands are Arrowhead, Deer Park, Hinkley Springs, Nursery Water, Ozarka and many more. DS Services and Nestle Waters North America are the most common manufacturers listed. The full list can be found on the International Bottled Water Association website.
Adding fluoride to drinking water is a highly protested practice. According to Real Farmacy, fluoride is added to 70 percent of drinking water despite peer-reviewed scientific evidence against the practice. The website claims that fluoride is a by-product of the phosphate fertilizer industry. According to the Lancet, a peer-reviewed medical journal, fluoride has been classified as a developmental neurotoxicant, meaning it can interfere with the normal development of a child.
Fluoride Alert states that while fresh surface water contains a small amount of fluoride, fluoridated water has a concentration about 14 to 24 times higher. The organization cites that in 2012, a spokesman for the American Dental Association admitted that drinking bottled water versus fluoridated drinking water did not lead to increased tooth decay. Fluoride is found in food, other beverages and most toothpastes. Too much exposure to fluoride can lead to fluorosis, a condition that stains teeth.
