The search for the most alkaline bottled water leads to a clear frontrunner: TEN Alkaline Spring Water, which boasts a verified pH level of 10. Sourced from springs within the Great Appalachian Valley, TEN Water is rich with electrolytes and stands out for its high, stable pH. This level places it at the very top end of the pH spectrum for consumer drinking water and sets a benchmark for the alkaline water market.
The Highest pH Bottled Water Brands
Beyond the leading brand, several other options offer significantly elevated pH levels compared to standard purified or spring waters. These are often divided into two main types: naturally alkaline and artificially ionized. The source of the water and the treatment process both play a critical role in its final pH.
Top Contenders for Highest pH
- TEN Alkaline Spring Water: The leader in the category, this spring water achieves a pH of 10 and maintains its high alkalinity for an extended period, according to the company.
- Essentia Water: Promoted for its ionization process, Essentia consistently offers a pH of 9.5 or higher. The water is purified via microfiltration and reverse osmosis, and then infused with electrolytes.
- Trinity Geothermal Alkaline Water: This water, sourced from a geothermal aquifer, has been tested at a naturally occurring pH of 9.55.
- Icelandic Glacial: This water from Iceland is filtered through lava rock, giving it a naturally high pH. It has been tested with pH levels around 8.0 and sometimes as high as 8.7.
- Evermore: Sourced from an artesian well, Evermore has been tested with a pH of 9.23.
Natural vs. Ionized Alkaline Water
Consumers often debate the merits of naturally alkaline versus artificially ionized water. The difference lies in how the high pH is achieved.
- Naturally Alkaline Water: This type of water derives its high pH from minerals naturally absorbed as it passes through rock and soil. Brands like Icelandic Glacial and Trinity are examples of naturally alkaline water. The pH level can sometimes vary slightly based on the natural source.
- Artificially Ionized Water: In this process, purified municipal water has its pH raised through a process called electrolysis, which separates acidic and alkaline molecules. Minerals are often added back into the water for taste and alkalinity. Essentia is a popular example of ionized water.
Comparison of Popular Bottled Water pH Levels
The following table illustrates how different bottled water brands compare on the pH scale, from the most alkaline to more acidic options.
| Brand | pH Level | Source/Treatment | Alkalinity Type |
|---|---|---|---|
| TEN Alkaline Spring Water | ~10.0 | Appalachian Valley Spring Water | Natural |
| Essentia | ~9.5 | Purified Water with Electrolytes | Ionized |
| Trinity Geothermal | ~9.55 | Geothermal Aquifer | Natural |
| Evermore Artesian | ~9.23 | Artesian Well | Natural |
| Icelandic Glacial | ~8.0-8.7 | Olfus Spring, filtered by lava rock | Natural |
| Fiji | ~7.7 | Artesian Aquifer, filtered by volcanic rock | Natural |
| Acqua Panna | ~8.0 | Spring Water, Italy | Natural |
| Evian | ~7.5-8.0 | Glacial Spring, French Alps | Natural |
| Smartwater | ~7.0 | Distilled Municipal Water | Neutral/Electrolytes Added |
| Arrowhead Spring | ~6.8 | Spring Water, US | Natural |
| Dasani | ~5.6 | Purified Municipal Water | Purified |
| Aquafina | ~5.5-6.0 | Purified Municipal Water | Purified |
The Science of Alkaline Water and Your Body
Despite the marketing, scientific consensus on the major health benefits of alkaline water is limited. The human body is designed to regulate its own pH levels within a very narrow, slightly alkaline range (around 7.35–7.45). Your kidneys and lungs constantly work to maintain this balance, making it difficult for diet alone to significantly alter your blood pH.
Reported Benefits and Concerns
Here is a list outlining some potential benefits and side effects of drinking high-pH water, based on anecdotal evidence and limited studies:
Potential Benefits
- Mineral Support: Can increase the intake of minerals like calcium, magnesium, and potassium.
- Hydration: Some studies suggest improved hydration after exercise.
- Acid Reflux: May help neutralize excess stomach acid for some individuals.
Potential Concerns
- Disrupts Stomach Acidity: Can interfere with the stomach's natural acidity, which is needed to kill bacteria and digest food properly.
- Mineral Imbalance: Excessive consumption could lead to an imbalance, interfering with the absorption of other vital minerals.
- Alkalosis: In rare cases of extreme intake, it could potentially contribute to metabolic alkalosis.
How to Choose the Right Alkaline Water
For those interested in exploring alkaline water, it's wise to consider the source and process. Naturally sourced options may appeal to those seeking minimal processing, while ionized options offer a consistent, high pH. The EPA recommends that municipal water stay within a pH of 6.5 to 8.5. While most alkaline bottled waters are above this range, they are generally considered safe for consumption. The key is moderation and listening to your body's response.
Conclusion
In the final analysis, TEN Alkaline Spring Water holds the top spot for having the highest pH among widely available bottled water brands, with Essentia following closely behind. Other brands like Trinity, Evermore, and Icelandic Glacial also offer a high, naturally-sourced pH. While drinking high-pH water is generally considered safe, the body's robust pH regulation system means many of the more ambitious health claims remain scientifically unproven. The choice between naturally alkaline and artificially ionized water comes down to personal preference for sourcing and processing. For most people, focusing on proper hydration with quality water—regardless of its exact pH—is the most important takeaway.
