Have a Drink of Oxygen

Can you drink your way to a better workout with super-oxygenated bottled water?


Although the performance-boosting pitch for pumped-up H2O is intriguing -- who doesn't want getting fit to feel like a walk in the park? -- several studies have failed to show any benefit from drinking oxygen-rich water before, during, or after exercise. No increased stamina, no improvement in heart rate, no speedy recovery time. So save your money and just turn on the tap.



Oxygenated waters can have up to 10 times more oxygen than regular bottled water, but that's the only claim that holds up. For starters, since oxygen doesn't dissolve well in water, most of it fizzes out shortly after you twist off the cap. (Think of how bubbles escape from a soda can when you pop the top.) Then there's this fact of life: Very little of the extra oxygen will make it from your gut to your bloodstream, because your intestines aren't great at transferring gases.



So what's with your neighbor who insists he runs faster after downing a bottle of high-test H2O? It's the placebo effect at work, not anything in the water.
