SEATTLE — A study published in the Journal of the American Medical Association (JAMA) has found that each of the five brands of oxygenated water the researchers tested contained less oxygen in 12 ounces than is contained in a single human breath, The Seattle Times reported.
The study was conducted by researchers at Seattle's Virginia Mason Medical Center and at Duke University in North Carolina. Testing 11 adults, they also found "no significant differences in exercise results" based on whether the person drank oxygenated bottled water or ordinary tap water, the article stated.
Two Northwest producers of oxygenated water responded to the study in different ways. A spokeswoman for Talking Rain, of Preston, WA, said the company makes no health claims for its product, called airwater, while Aqua Rush, of Coeur d'Alene, ID, told the paper that its oxygen-infusing technique gives its product a higher level of "stable" oxygen than any others.
The researchers would not identify any of the five brands they tested, nor whether either of the Northwest brands was included in the study, according to the paper.
