Ionized Water: Is It Really Good for You?
Curious about ionized water? Discover the science-backed benefits, how it differs from regular water, and why it might be the hydration upgrade your body deserves.


Published April 23, 2025.

You've probably heard the buzz about ionized water and its potential health benefits. But what exactly is it, and could it be the hydration upgrade you've been looking for?
Let's look into the science behind ionized water and discover what it can do for your well-being.

What Is Ionized Water?
Water consists of hydrogen and oxygen atoms at its core. When electricity passes through water, it splits into hydrogen and oxygen ions or atoms carrying an electrical charge, which is ionized water.
The process happens in a water ionizer with a cathode (negative terminal) and an anode (positive terminal) immersed in a salt solution. As electricity flows, the water separates into acidic and alkaline components. The alkaline stream has a pH greater than 7, which is considered neutral on the pH scale.
To put this in perspective, lemon juice has a highly acidic pH of 2.2, while human blood maintains a slightly alkaline pH of 7.45. The alkaline nature of ionized water is where many of its potential benefits originate.

Health Benefits of Drinking Ionized Water
Ionized water offers several evidence-backed benefits that set it apart from regular filtered water:
- Refreshing Taste: Many people describe ionized water as sweeter and more refreshing.
- Reduced Risk of Metabolic Syndrome: Studies show alkaline ionized water may lower risks of high blood sugar, blood pressure, and waist circumference [1].
- Potential Longevity Support: A 3-year study found that drinking alkaline water increases lifespans [2].
- Relief From Chronic Conditions: Research also showed reduced pain and inflammation in gout patients [3].

Targeting Specific Health Conditions with Ionized Water
Researchers found that adults who consumed alkaline ionized water had better hydration status, reduced muscle fatigue, and improved exercise performance than those who drank ordinary water [4].
Gastrointestinal symptoms, such as bloating, nausea, stomach pain, acid reflux, and diarrhea, significantly improved in those who drank alkaline ionized water.
Another promising study showed the ability of ionized water to mitigate cancer growth [5]. Alkaline ionized water provides an alkaline environment to reduce cancer growth and fights cellular damage and inflammation.

Ionized vs. Alkaline Water: What's the Difference?
Though often used interchangeably, there's a key difference between ionized and alkaline water. Alkaline water can occur naturally in mountain springs rich in alkaline minerals or soda lakes with pH values of 9 or higher.
Beyond being alkaline, ionized water contains ions with antioxidant and anti-inflammatory properties. This makes it particularly beneficial for managing chronic conditions like diabetes or gout.
Both waters effectively support hydration, but alkaline water might give you an edge in performance and recovery if you're into competitive sports.

Practical Uses for Ionized Water
The benefits of ionized water extend beyond hydration:
- Rice cooked in alkaline ionized water has improved texture, flavor, aroma, and digestibility
- Its antimicrobial properties make it excellent for disinfecting and cleaning
- You can use it to clean fruits and vegetables more effectively
- There are potential benefits for treating certain skin conditions

Modern Approaches to Water Enhancement
The traditional water ionizer splits water into hydrogen and oxygen streams using an electric current. A semi-permeable membrane prevents the two streams from mixing.
But the type of materials used to make the electrodes influences electrolysis efficiency. Some materials can corrode quickly and contaminate the water.
Specialized water enhancement systems, such as MAYU's vortexing technology, go beyond just alkalizing water.
The system restructures the water molecules by creating gentle swirls, enabling our cells to absorb water more efficiently. The aeration process removes CO2 and volatile organic compounds and increases pH levels naturally and safely.
A Balanced Approach to Ionized Water
While ionized water offers many benefits, it's important to maintain perspective before drinking:
- Those with kidney, heart, or liver conditions should consult their doctor first.
- Safety during pregnancy and lactation isn't fully established.
- Very high pH levels (above 9.8) should be avoided.
For most adults, consuming 500 ml to 1 liter of ionized water daily appears beneficial. Athletes and physically active individuals might benefit from up to 10 ml per kg of body weight.
