Q: Can drinking oxygenated water have any health benefits?
A: No. Makers of oxygenated water (bottled or canned) claim the water is infused with at least seven times more oxygen than regular water. This, supposedly, will help your muscles, improve athletic performance, and “purify” the body.
But this makes no sense. First, there’s little free oxygen gas in water to begin with; adding more doesn’t amount to much. Even if it does contain extra oxygen, a bottle of oxygenated water would have less oxygen than the amount you get taking a single breath.
Most important, it doesn’t matter how much oxygen is in the water because we absorb oxygen into our blood through our lungs, not our digestive tract. And, in general, healthy people’s blood already contains all the oxygen it needs. Adding a little more won't improve health or performance.
