Which Bottled Water Is Naturally Alkaline? A Comprehensive Guide

5 min read

According to the UK's Drinking Water Inspectorate, natural water typically has a pH between 6.5 and 8.5, and when this is above 7, it is considered alkaline. However, not all bottled alkaline water is created equal; many brands artificially boost their pH. Understanding which bottled water is naturally alkaline is key for consumers seeking mineral-rich, unprocessed options.

Quick Summary

Several brands offer naturally alkaline bottled water, which gains its high pH from minerals absorbed as it filters through rock formations at its source. Brands like Fiji, Icelandic Glacial, and Eternal are sourced from volcanic or deep spring aquifers, providing a mineral-rich composition without artificial additives. This guide explores the difference between natural and enhanced versions, highlights leading brands, and outlines the benefits of each.

Key Points

  • Source is Key: Naturally alkaline water gets its pH from minerals absorbed from geological rock formations like volcanic rock or limestone.

  • Fiji Water: Is a naturally alkaline artesian water, filtered through volcanic rock and sourced from an aquifer in the Fiji Islands.

  • Eternal Water: Another naturally alkaline option, sourced from protected springs and aquifers in the U.S., with a pH ranging from 7.8 to 8.2.

  • Icelandic Glacial: Bottled from Iceland's Ölfus Spring, this water is naturally filtered through lava rock and has a pH of 8.4.

  • Not All Alkaline Is Natural: Many brands use electrolysis or added minerals to artificially increase the pH of purified water, distinguishing them from naturally sourced options.

  • Minimal Processing: Naturally alkaline brands like Mountain Valley Spring Water often undergo minimal processing, retaining their natural mineral balance.

  • Health Claims Are Debated: While marketed with health benefits, scientific consensus on the superiority of alkaline water over regular water is still developing.

The Difference Between Naturally Alkaline and Artificially Enhanced Water

The fundamental difference between naturally and artificially alkaline water lies in its source and processing. Naturally alkaline water originates from springs or aquifers where water flows through mineral-rich rock layers, like limestone or volcanic rock. During this process, it absorbs minerals such as calcium, magnesium, potassium, and bicarbonates, which naturally increase its pH level. This results in a mineral-rich profile with inherent alkalinity.

Conversely, artificially enhanced alkaline water starts as regular tap or purified water and undergoes a process called electrolysis or has minerals and additives infused post-filtration. While this can achieve a higher pH, it lacks the naturally occurring mineral composition and potential benefits found in spring-sourced water. Some popular brands use this method, while others rely purely on natural sourcing.

The health considerations of alkaline water

While marketing for alkaline water often touts numerous health benefits, such as neutralizing acid reflux, improving hydration, and slowing biological aging, the scientific consensus is mixed. Some studies suggest potential benefits for specific conditions, such as reducing pepsin activity in acid reflux sufferers or improving viscosity in dehydrated athletes. However, many health professionals caution that robust, large-scale studies on humans are still needed to confirm these claims.

It's also important to note that the human body is designed to regulate its own pH levels, and drinking alkaline water is not a shortcut to overall bodily pH balance. Natural alkaline water is generally considered safe for consumption as it contains beneficial minerals. However, some concern exists regarding artificially ionized water, particularly for those with kidney issues, as excessive consumption could potentially interfere with mineral absorption. Always consult a healthcare professional with specific health concerns.

How natural alkalinity is formed

The geological journey of water is what makes it naturally alkaline. As rainwater or snowmelt seeps into the ground, it travels through different rock and soil layers. Along this path, it collects dissolved minerals. For instance, water passing through limestone absorbs calcium and magnesium bicarbonates, increasing its pH. Water sourced from areas with volcanic rock, such as Fiji or Iceland, interacts with these specific mineral deposits to achieve its high pH naturally.

This process is entirely natural and doesn't require any chemical manipulation. This is what differentiates true natural alkaline water from products that are artificially processed and supplemented with minerals after purification. The mineral content from the natural source gives the water its distinct taste profile and inherent benefits.

The environmental impact of bottled water

When considering your choice of bottled water, the environmental impact is a significant factor. Brands that source water from across the globe, like Fiji or Evian, have a large carbon footprint due to transport. Many brands are shifting to more sustainable packaging, including glass bottles (like Mountain Valley) and plant-based cartons (like Flow) to mitigate plastic waste. Consumers can support these more environmentally conscious brands or opt for local spring water sources to reduce their carbon footprint. Making an informed choice involves balancing personal health preferences with environmental considerations.

Conclusion

For those seeking a bottled water with a naturally high pH, several brands offer excellent options. Fiji, Eternal, Icelandic Glacial, Mountain Valley, and Flow are all sourced from unique geological formations that enrich the water with natural minerals and electrolytes, providing inherent alkalinity without artificial processing. While scientific evidence on health benefits is still evolving, choosing naturally alkaline water ensures a mineral-rich and less processed product. Evaluating factors like sourcing, packaging, and personal taste preferences can help you find the best naturally alkaline bottled water for your needs.
