Active O2 and Oxygenated Water Explained
Active O2, produced by Adelholzener, is a brand of oxygenated mineral water that includes added oxygen, electrolytes, and flavorings. The manufacturer claims that this extra oxygen can provide health benefits beyond simple hydration, such as boosting energy and improving athletic performance. The process, often called aeration, involves infusing water with a higher concentration of dissolved oxygen than naturally occurs. While this creates a unique, sometimes described as 'crisper' taste, its physiological impact on the human body is a point of contention among experts.
The Science (or Lack Thereof) Behind the Claims
Multiple controlled studies have investigated the effects of oxygenated water on physical performance and have consistently found no significant difference between subjects who consumed oxygenated water and those who consumed regular water. These studies measured factors like maximal oxygen uptake, blood lactate levels, and time to exhaustion, showing that the minute quantities of extra oxygen are physiologically insignificant.
Experts point out that the human body's respiratory system is highly efficient at absorbing oxygen through the lungs, and the amount of oxygen that can be absorbed through the gastrointestinal tract from water is negligible. One breath of fresh air contains more oxygen than a litre of hyperoxygenated water, putting the purported benefits into stark perspective. Marketing tactics often leverage the general knowledge that oxygen is vital for life to imply that 'more is better,' even if the delivery method is ineffective.
Why the Flavoring and Electrolytes?
Unlike plain tap or bottled water, Active O2 is often a flavored beverage, with options like apple, citrus, and orange. The pleasant taste makes it a more appealing option for some consumers who might otherwise find plain water boring. Additionally, some versions include electrolytes, which can be beneficial for athletes needing to replenish lost minerals after intense exercise. For the average person, a balanced diet is sufficient for electrolyte intake, making the added cost of flavored, oxygenated water potentially unnecessary for daily hydration.
Comparison: Active O2 vs. Regular Water
| Feature | Active O2 (Oxygenated Water) | Regular Water (Tap or Bottled) |
|---|---|---|
| Composition | Mineral water with added oxygen, flavors, and electrolytes | Plain H₂O, may contain naturally occurring minerals |
| Oxygen Content | Infused with a higher concentration of dissolved oxygen | Contains naturally dissolved oxygen, significantly less than in Active O2 |
| Cost | Significantly more expensive due to processing and marketing | Affordable and widely accessible |
| Taste | Flavored options available, often described as crisp | Tasteless, though can vary slightly depending on the source |
| Proven Benefits | Primarily offers hydration and flavor. The effects of added oxygen are not substantiated | Provides essential hydration for proper bodily function |
| Target Audience | Marketed towards fitness enthusiasts and health-conscious consumers | Universal for all hydration needs |
The True Verdict on Active O2 vs. Regular Water
Ultimately, the choice between Active O2 and regular water boils down to personal preference for taste and willingness to pay for unproven benefits. Scientific evidence overwhelmingly suggests that the extra oxygen infused into Active O2 does not provide a meaningful physiological advantage over regular water. Your respiratory system, not your digestive system, is responsible for meeting your body's oxygen demands. While Active O2's flavors can make hydration more enjoyable for some, plain water remains the most effective, economical, and scientifically validated choice for staying hydrated.
Can Oxygenated Water Boost Athletic Performance?
No, robust scientific research shows that drinking oxygenated water does not significantly enhance athletic performance or recovery. The quantity of oxygen provided is miniscule compared to what is absorbed through breathing.
Is the Added Oxygen in Active O2 Absorbed?
While a minimal amount may be absorbed through mucous membranes, the majority of the added oxygen is not effectively absorbed through the digestive system and does not significantly impact blood oxygen levels.
Is Active O2 Just Flavored Water?
In essence, for the average person, it functions much like flavored water. The primary difference from plain flavored water is the inclusion of extra dissolved oxygen, the benefits of which are scientifically unproven.
Is Active O2 Hydrating?
Yes, like any water-based beverage, Active O2 is hydrating. However, it is not more hydrating than regular water, as the extra oxygen does not improve the body's hydration processes.
Why Do People Report Feeling More Energetic?
Reported energy boosts are likely due to the placebo effect or simply the act of rehydrating. If a person believes a product will enhance their performance, their perception and effort can sometimes reflect that belief.
Are There Any Risks to Drinking Active O2?
For most people, drinking Active O2 is generally safe. The primary risk is financial, as you are paying a premium for a product whose key health claims are not supported by science.
What About the Electrolytes in Active O2?
Some varieties of Active O2 contain electrolytes, which can be helpful for those who have sweated heavily. However, for everyday hydration, a balanced diet provides sufficient electrolytes. For serious athletes, a more specifically formulated sports drink may be more effective.
