What is Alkaline Reduced Water?
Alkaline reduced water (ARW), also known as electrolyzed reduced water (ERW), is a type of water that has a higher pH level than standard drinking water (typically above 7.0) and a negative oxidation-reduction potential (ORP). The negative ORP indicates antioxidant properties, which are attributed to the presence of dissolved molecular hydrogen gas. The electrolysis process used by ionizers produces this dissolved hydrogen, setting it apart from simply adding alkaline minerals to water.
Method 1: The Baking Soda Method
One of the simplest and most accessible ways to increase your water's alkalinity is by adding baking soda. This DIY method is affordable and can be done instantly with ingredients you likely already have. However, it is important to note that this method does not produce the dissolved hydrogen that provides the 'reduced' aspect of ARW, but it does effectively raise the pH.
How to Prepare Water with Baking Soda
- Use filtered water to start. While tap water is fine, filtered water ensures you aren't adding baking soda to water with other contaminants.
- Add a small amount of aluminum-free baking soda to the water. A good starting point is about 1/8 to 1/2 teaspoon per eight ounces of water.
- Stir the mixture thoroughly until the baking soda is completely dissolved. Adding it gradually can help prevent excessive fizzing.
- Use pH test strips or a digital meter to check the pH level. The goal is to reach a gently alkaline level, typically between 8 and 9.5. Avoid excessively high pH levels, which can be detrimental.
Method 2: Using a Water Ionizer
For those serious about consistent, high-quality alkaline reduced water, a home water ionizer is the most effective solution. These countertop or under-sink units use a process called electrolysis to create both alkaline reduced water and acidic water. The machine is equipped with platinum-coated titanium plates that pass an electrical current through the water, separating it into streams of high-pH and low-pH water.
How Water Ionizers Work
- The machine connects directly to your home's water supply.
- Water is first filtered to remove contaminants like chlorine and heavy metals.
- The filtered water enters an electrolysis chamber where an electric current separates the acidic and alkaline components.
- The alkaline reduced water, rich in dissolved hydrogen and with a negative ORP, is dispensed from the main spout for drinking.
- The acidic water, which is not for consumption, is expelled through a separate hose and can be used for cleaning or beauty purposes.
Method 3: Using Alkaline Mineral Drops
If you want the convenience of increasing alkalinity without the cost of a high-end ionizer, commercially available alkaline mineral drops are another option. These drops contain a concentrated mix of alkaline minerals like potassium, magnesium, and calcium.
How to Use Alkaline Mineral Drops
- Follow the manufacturer's instructions for the correct number of drops per glass or bottle of water.
- Add the drops to your filtered water and shake or stir well.
- As with other methods, it's wise to test the pH periodically to ensure you're getting the desired level.
How to Measure Your Water's pH and ORP
Regardless of the method you choose, it is crucial to verify your water's pH and, for reduced water, its ORP. Measuring helps ensure you are creating water that is in a safe and beneficial range.
Tools for Measuring Water
- pH Test Strips: Inexpensive and easy to use, these papers change color when dipped into water, and the color is compared to a chart to determine pH. They offer a quick, but less precise, measurement.
- Digital pH Meter: For greater accuracy, a digital meter uses an electrode to provide a specific numerical pH reading.
- ORP Meter: A specialized meter is needed to measure the oxidation-reduction potential. This is especially important when using a water ionizer to confirm the water is truly 'reduced'.
Method Comparison: DIY vs. Ionizer
To help decide which method is right for you, here is a breakdown of key differences:
| Feature | Baking Soda Method | Water Ionizer | Alkaline Mineral Drops |
|---|---|---|---|
| Cost | Very Low | Very High | Medium |
| Ease of Use | Very Easy | Moderate (Installation) | Very Easy |
| Equipment | Spoon, Baking Soda | Ionizer Machine | Concentrated Drops |
| Reduced (ORP) | No | Yes | No |
| Mineral Content | Sodium only | Added via electrolysis | Added via drops |
| Consistency | Manual, requires testing | Automated, consistent | Requires manual dosage |
| Safety Risk | High pH if overused | High pH if settings are too strong, electrode degradation | High pH if overused, chemical spills |
| Best For | Casual users | Serious, long-term use | Travelers, occasional use |
Important Safety Considerations
While alkaline reduced water has proponents, it is not without risks, especially if consumed excessively or at very high pH levels. High alkalinity can disrupt your body's natural pH balance and affect nutrient absorption, especially for those with low stomach acid. People with kidney disease are at a particularly high risk of developing hyperkalemia (high blood potassium) from drinking high pH water, and should consult a doctor before use. High pH levels can also cause electrode degradation in ionizers, potentially leaching heavy metals into the water. It is recommended to keep drinking water pH below 9.8 to minimize these risks.
Conclusion
Making alkaline reduced water is possible through several different methods, each with its own level of convenience and cost. For a simple pH boost, the baking soda method or mineral drops are sufficient. However, to get true alkaline reduced water with a consistent negative ORP and dissolved hydrogen, a water ionizer is the most reliable option. Regardless of your chosen method, exercising moderation and monitoring your water's pH is crucial. For anyone with underlying health conditions, especially kidney problems, consulting a healthcare professional is strongly advised before making a daily practice of consuming alkaline reduced water. By understanding the processes and risks, you can make an informed choice that best fits your wellness goals.
