Do you drink tap water, regular bottled water, or oxygenated (also known as “super-oxygenated”) water? Do you think any one of these choices makes a difference?
Some people have said they feel more energized after drinking oxygenated water. Some people feel no difference at all. With our bodies being composed of 60% water and the need for oxygen to sustain life perhaps there is something to this oxygenated water thing after all…or is there?
The American Council on Exercise (ACE) sponsored a study in 2001 using a few of the oxygenated (or “super-oxygenated”) waters out there on the market at the time. The purpose was to test the theory that the body would absorb the extra oxygen from the oxygenated water, thus resulting in improved stamina and athletic performance, reduced recovery time, and better mental clarity. The conclusion of the study was that the oxygenated water showed no measurable effects on blood pressure and heart rate and that it was no more beneficial than tap water. Any potential benefits were assumed to be a result of the placebo effect.
In 2006, a study was conducted to test the placebo effect using, once again, oxygenated water. Participants either drank bottled water or water that they thought was “super-oxygenated”. That conclusion was the same, in showing no relationship between the type of water and exercising.
The Journal of the American Medical Association (JAMA) published a research letter to the editor regarding oxygenated water. Five brands of oxygenated water and tap water were tested to measure the amounts of oxygen contained in each. Study participants were asked to then perform certain standard exercises, however, 5 minutes prior to each exercise each participant drank in random order either the oxygenated water or a bottle of the same brand that had been deoxygenated. Neither the participants nor the researchers knew which one was which. The study found there were no differences in the exercise results.
Further research needs to be conducted to see if oxygenated water truly makes a difference or if it is all just marketing hype to boost product sales. Just don’t forget what water is to begin with: H2O. It already is made up of oxygen remember, so will buying oxygenated (or “super-oxygenated”) water make that much of a difference? Probably not.
