Do oxygenated waters deliver more oxygen?
Manufacturers of oxygenated water claim that it contains up to 40 per cent more oxygen as ordinary water, and that it can enhance sports performance. These claims were tested in a recent study in the Journal of the American Medical Association when volunteers exercised to exhaustion on two different days, once after drinking the oxygenated water and once after drinking the same brand with oxygen removed. There was no significant difference in performance between the two tests, with the researchers adding that a single breath contains more oxygen than a bottle of oxygenated water.
