Bottled waters infused with extra oxygen may provide no more exercise benefits than breathing ordinary air, a medical expert told the Beveragedaily.com news service earlier this year, as also reported this week by the The Water Connoisseur newsletter.
Dr. Claude Piantadosi, director of the Center for Hyperbaric Medicine and Environmental Physiology at Duke University Medical Center, wrote in the British Journal of Sports Medicine that there is more oxygen in a breath of fresh air than in a liter of the most "hyperoxygenated" bottled waters, according to the report.
Piantadosi said several studies suggest that the body can ingest only very small amounts of oxygen from drinking water compared with the amount required for exercise and that no significant amount of oxygen is absorbed through the intestine, according to Beveragedaily.com.
Bottled waters promoting their added oxygen, some at premium prices, have been big sellers in recent years; one such brand, Netherlands-based OGO, claims to have 35 times the oxygen of ordinary water.
The OGO Web site says this: "OGO oxygen products, in the form of water or oxygen canisters, enhance your everyday life. Use them to awaken your senses for the busy day ahead, whether you need to stay alert during meetings or whether you are in preparation for active sports. OGO helps you perform to the best of your abilities by enabling faster recovery from fatigue."
An OGO spokesman earlier this year told Beveragedaily.com that the company makes no medical claims "because we haven't done that kind of research," but he added that there was considerable anecdotal and documentary evidence that the water improved customers' well-being, although the effects could be partly psychological.
Supplementary oxygen in air is used in medical situations to aid breathing and may have benefits during exercise, according to the report.
