Oxygenated water is water that has extra oxygen added to it during the bottling or canning process, raising the waters dissolved oxygen levels. The added oxygen is claimed to provide health benefits, including aiding exercise recovery, flushing toxins out of the body, and improving alcohol metabolism. However, evidence to support these benefits is limited, and most of the oxygen may escape the bottle when opened. While studies on oxygenated water are limited, some suggest that it may offer some benefits, such as improving lactate clearance during exercise. Nevertheless, more research is needed to confirm these benefits. Drinking oxygenated water is not harmful, but it doesnt contain any significant nutrients.
