My doctor said the GI tract does not absorb oxygen from water and that drinking oxygen-rich water is a waste of time and money. Why would he say this?
It is true that your GI tract is not designed to absorb gases such as oxygen. But your GI tract CAN and DOES absorb liquid. Your GI tract absorbs liquid saturated with oxygen, just as it absorbs liquid with no oxygen, liquids with sugar, such as soft drinks, and liquids which scavenge oxygen, such as alcohol. Oxygen becomes a property of the water itself – it is no longer a free gas. This is a law of physics easily referenced.
