Understanding Alkaline Water and the pH Scale
Alkaline water has a higher pH than regular tap water. The pH scale measures acidity and alkalinity from 0 to 14, with 7 being neutral. Below 7 is acidic, and above 7 is alkaline. While bottled alkaline water is readily available, you can also make it by adding minerals or using specific filtration methods.
Method 1: The Baking Soda Technique
A simple and inexpensive way to raise water's pH is by using baking soda (sodium bicarbonate).
How to do it:
- Add about 1/8 teaspoon of baking soda to 8 ounces of filtered water.
- Stir until it is fully dissolved.
Considerations for this method:
Baking soda can give water a slightly salty taste. It also adds sodium, which is a concern for those on low-sodium diets. You can use a pH test kit to check the water's pH level.
Method 2: The Lemon or Lime Infusion
Adding lemon or lime to water, despite their initial acidity, can create an alkalizing effect after the body metabolizes their minerals.
How to do it:
- Add slices of lemon or lime to a pitcher of about 64 ounces of filtered water.
- Let it steep for 8 to 12 hours at room temperature.
Why it works:
The alkaline minerals from the fruit remain after digestion, adding a refreshing taste and contributing to the body's alkaline load.
Method 3: Using pH Drops
For a convenient and controlled approach, pH drops containing concentrated alkaline minerals are available.
How to do it:
- Add the recommended number of drops to a glass of water.
- Stir or shake.
Advantages of this method:
This method is portable and provides a consistent way to increase water's pH.
Method 4: Mineral-Adding Water Filters
Filter systems can provide a continuous supply of alkaline water.
Options for filtration:
- Alkaline Filter Pitchers: These pitchers use cartridges with minerals like calcium and magnesium to raise pH.
- Under-Sink Remineralization Filters: These can be added to reverse osmosis systems to restore beneficial minerals and increase pH.
Method 5: Water Ionizers
Water ionizers are the most advanced option, using electrolysis to separate water into alkaline and acidic streams.
How ionizers work:
Electrodes split water, creating separate alkaline and acidic outputs. Most models allow you to choose the desired pH level.
Comparison of Methods: DIY vs. Equipment
| Feature | DIY Methods (Baking Soda, Lemons) | Equipment (Filters, Ionizers) |
|---|---|---|
| Cost | Very low | High initial investment, plus replacement parts |
| Ease of Use | Simple, but requires daily preparation | Convenient and automated once set up |
| pH Consistency | Can be inconsistent due to manual measurements | Highly consistent and often customizable |
| Mineral Content | Varies by ingredient; baking soda adds sodium, lemon adds potassium | Adds a balanced profile of minerals like calcium and magnesium |
| Maintenance | Minimal | Requires filter changes and/or periodic cleaning |
| Portability | Excellent for small, individual batches | Fixed in place; not portable |
Potential Benefits and Safety Considerations
Research on the health benefits of alkaline water is limited. Some studies suggest it might help with acid reflux by deactivating pepsin and potentially improve rehydration in athletes.
Important Safety Reminders
The body naturally regulates its pH. Excessive alkaline water intake could potentially interfere with this, possibly leading to metabolic alkalosis with symptoms like nausea in rare cases. Those with kidney problems should avoid alkaline water without a doctor's advice.

Conclusion
Making alkaline water at home is possible using simple methods like baking soda or lemon, or more advanced filters and ionizers. While DIY options are cheaper, equipment offers more convenience. It's crucial to consume alkaline water moderately and consult a healthcare professional, especially with existing health conditions.
