Debunking oxygenated water: Why 'oxygen-nanobubble' performance claims lack scientific evidence
By
Asker Jeukendrup and Nick Tiller
Summary
This article critically examines the pseudoscience behind oxygenated water products, specifically debunking a recent study claiming that an 'oxygen-nanobubble beverage' can improve athletic performance by 2.4-7.1%. The author argues that there is no plausible biological mechanism for orally consumed oxygen to enhance performance, as oxygen is absorbed through the lungs, not the gut. The piece systematically dismantles the study's methodology, highlighting issues like lack of blinding, inappropriate statistical analyses, and conflicts of interest. It concludes that such products are marketing gimmicks preying on wishful thinking, and calls for better scientific literacy and skepticism in sports nutrition.
