What Is Alkaline Water?

Alkaline water is water that has a pH level higher than 7, which is considered neutral on the pH scale. Most alkaline waters have a pH between 8 and 10, though some products claim pH levels as high as 11 or 12. The term “alkaline” refers to the water's position on the pH scale, indicating it is less acidic than neutral water.

To understand alkaline water, it helps to know that pH stands for “potential of hydrogen.” It measures the concentration of hydrogen ions in a solution. The more hydrogen ions present, the more acidic the solution; the fewer hydrogen ions, the more alkaline (or basic) it becomes. This is a logarithmic scale, meaning each whole number change represents a tenfold difference in acidity or alkalinity.

Water becomes alkaline in one of two primary ways: naturally, when water flows over rocks and picks up minerals like calcium, magnesium, and potassium, or artificially, through a process called ionization (electrolysis) or by adding alkaline minerals directly to the water.

Regular tap water in the United States typically has a pH between 6.5 and 8.5, as regulated by the Environmental Protection Agency (EPA). This range is considered safe for drinking. Most bottled waters also fall within this range, with some being slightly acidic (pH 6.5-7) due to the purification processes used or natural carbon dioxide absorption.

The appeal of alkaline water extends beyond just pH. Many proponents point to additional properties such as mineral content, oxidation-reduction potential (ORP), and perceived taste improvements. However, it is important to evaluate these claims critically and understand what science supports versus what remains theoretical.

In South Florida, where Hydralife operates, tap water quality varies by municipality. Miami-Dade and Broward County water tends to be slightly alkaline due to the limestone aquifer, but it also contains chloramines and may have other contaminants that affect taste and quality. This is one reason many residents seek alternative water sources. For a deeper comparison, see our article on alkaline water versus tap water.

The Science of pH: Understanding Acidity and Alkalinity

The pH scale is a foundational concept in chemistry that measures how acidic or basic (alkaline) a substance is. The scale runs from 0 to 14, with 7 being perfectly neutral. Solutions with a pH below 7 are acidic, while those above 7 are alkaline. This scale was developed by Danish biochemist Soren Peter Lauritz Sorensen in 1909 and remains the standard measurement today.

What makes the pH scale particularly interesting is its logarithmic nature. This means that each unit change represents a tenfold difference in hydrogen ion concentration. For example, water with a pH of 6 is ten times more acidic than water with a pH of 7, and water with a pH of 5 is one hundred times more acidic than pH 7 water. This logarithmic relationship helps explain why even small pH changes can have significant effects.

In everyday life, we encounter substances across the entire pH spectrum. Lemon juice (pH 2) and vinegar (pH 2-3) are common acidic substances. Baking soda solution (pH 9) and household ammonia (pH 11) are alkaline. Our own bodies contain areas with vastly different pH levels: stomach acid is highly acidic (pH 1.5-3.5) to break down food, while our blood is maintained at a slightly alkaline pH of 7.35-7.45.

Understanding pH is essential when evaluating alkaline water claims. While it is true that many processed foods and beverages are acidic (sodas, coffee, alcohol), the human body has robust systems for maintaining internal pH balance. Your lungs, kidneys, and blood buffers work together to keep your blood pH stable regardless of what you consume.

This is where we need to be careful about claims. Drinking alkaline water will not “alkalize your body” or significantly change your blood pH - and this is actually a good thing. If your blood pH changed dramatically, it would be a medical emergency. What alkaline water may do is provide temporary localized effects, such as neutralizing stomach acid (similar to how antacids work) and potentially affecting the digestive environment.

How Alkaline Water Is Made: Natural vs. Ionization

There are several methods for producing alkaline water, each with different characteristics and outcomes. Understanding these methods helps you evaluate the various alkaline water products available and choose one that aligns with your preferences and values.

Natural Mineral Alkaline Water

In nature, water becomes alkaline as it flows through mineral-rich environments. Spring water that passes over rocks containing calcium, magnesium, potassium, and other minerals absorbs these elements, raising its pH naturally. Famous alkaline spring waters from places like Fiji, Iceland, and certain mountain regions acquire their mineral content and alkalinity through this geological process that can take years or decades.

This natural mineralization typically produces water with a pH between 7.5 and 8.5, though some sources can reach pH 9 or higher. The mineral content gives this water its characteristic taste and potential health properties. Natural mineral water is generally considered safe and beneficial, as humans have consumed it throughout history.

Ionization (Electrolysis)

Ionization is the most common method for producing alkaline water commercially. This process uses electrolysis to separate water into acidic and alkaline streams. Here is how it works:

Ionized water typically has a negative oxidation-reduction potential (ORP), which proponents claim gives it antioxidant properties. ORP measures the ability of a substance to oxidize (positive ORP) or reduce (negative ORP) other substances. While the antioxidant claims are still being studied, this is one of the distinguishing features of ionized alkaline water.

Mineral Addition

Some manufacturers create alkaline water by adding minerals such as calcium carbonate, magnesium oxide, or potassium bicarbonate to purified water. This method raises the pH and provides mineral content but does not produce the negative ORP associated with ionization.

The Hydralife Process

At Hydralife, we use a comprehensive six-step process that combines the benefits of thorough filtration, mineral enhancement, and ionization:

Ionized vs Alkaline Water: Understanding the Key Differences

One of the most common points of confusion in the alkaline water space is the difference between “ionized alkaline water” and “alkaline water.” While all ionized alkaline water is alkaline, not all alkaline water is ionized. This distinction matters because the two types have different properties and potential effects.

What Is ORP and Why Does It Matter?

ORP (Oxidation-Reduction Potential) measures a substance's ability to act as an oxidizer or a reducer. Positive ORP indicates oxidizing potential (like chlorine in pool water), while negative ORP indicates reducing (antioxidant) potential.

Ionized alkaline water typically has a negative ORP ranging from -200 to -800 mV (millivolts). Proponents claim this gives the water antioxidant properties, potentially helping to neutralize harmful free radicals in the body. However, it is important to note that the body has its own sophisticated antioxidant systems, and the extent to which drinking water with negative ORP contributes to antioxidant activity remains an area of ongoing research.

The molecular structure claims about ionized water (smaller water clusters or “micro-clustering”) are more controversial. While some proponents claim that electrolysis creates smaller water molecule clusters that can be absorbed more easily by cells, the scientific evidence for this is limited and the claims are not universally accepted by the scientific community.

Potential Health Benefits of Alkaline Water

The potential health benefits of alkaline water have been the subject of both enthusiastic claims and scientific scrutiny. Here, we will present what proponents suggest while being clear about what evidence supports these claims. It is essential to approach this topic with balanced expectations.

It is worth noting that proper hydration itself provides numerous health benefits, including better cognitive function, improved physical performance, healthier skin, and support for kidney function. If drinking alkaline water encourages you to stay better hydrated because you prefer the taste or experience, that alone is a meaningful benefit.

What the Research Says: A Balanced Scientific Perspective

Scientific research on alkaline water is still evolving. While there are promising studies, it is important to understand that much of the research has limitations, and more large-scale clinical trials are needed to draw definitive conclusions. Here is an honest assessment of where the science stands.

Studies Supporting Potential Benefits

• Acid Reflux Study (Koufman & Johnston, 2012)

  Found that water with pH 8.8 irreversibly inactivated human pepsin in laboratory conditions, suggesting potential for acid reflux management. Published in The Annals of Otology, Rhinology & Laryngology.

• Blood Viscosity Study (Weidman et al., 2016)

  A study of 100 adults found that those who drank high-pH water had reduced blood viscosity by 6.3% compared to 3.36% for standard water after exercise. Published in the Journal of the International Society of Sports Nutrition.

• Hydration Status Research

  Multiple smaller studies have shown improvements in hydration markers when participants consumed alkaline water, particularly after exercise.

Limitations and Areas Needing More Research

• Small Sample Sizes

  Many studies have small participant groups, making it difficult to generalize findings to the broader population.

• Short Duration

  Most studies are short-term, and long-term effects of regular alkaline water consumption are not well documented.

• Placebo Effects

  Some reported benefits may be due to placebo effects, especially in studies where participants knew they were drinking alkaline water.

• Lack of Replication

  Many positive findings have not been consistently replicated by independent researchers.

Our perspective at Hydralife is that alkaline water is a safe, pleasant-tasting hydration option that may offer some benefits, but it should not be viewed as a miracle cure or replacement for medical treatment. We encourage our customers to drink alkaline water as part of a healthy lifestyle while maintaining realistic expectations about what it can and cannot do.
