Can you add something to water to make it alkaline?

3 min read

Alkaline water, defined as having a pH of 8 or higher, can be created by adding certain substances to water. This practice has grown in popularity due to purported health benefits.

Quick Summary

Several methods are available for creating alkaline water at home, such as adding baking soda or using pH drops. Equipment like alkaline pitchers and ionizers are also available. Caution should be used with some methods and products.

Key Points

  • Baking Soda Method: Add ⅛ teaspoon of baking soda to 8 ounces of filtered water to create an instant alkaline solution with a pH of around 9.0.

  • pH Drops: Highly concentrated mineral drops are a precise and portable way to raise water's pH reliably by following the manufacturer's instructions.

  • Alkaline Water Filters: Specialized pitchers and filter systems add beneficial minerals like calcium and magnesium while filtering impurities, offering a consistent supply of alkaline water.

  • Lemon Water Myth: Adding lemon juice to water makes it more acidic, and its supposed alkalizing effect on the body is a health myth not supported by scientific evidence.

  • Risks and Regulation: Excessive consumption of alkaline water, especially with a pH over 9.8, can carry risks like mineral imbalances or metabolic alkalosis, particularly for those with certain health conditions.

  • Body's pH Balance: Your body has its own robust, naturally controlled systems for maintaining a stable blood pH, which is not significantly affected by diet or drinking water.

  • Best for Everyday Hydration: Pure, filtered water with a neutral pH remains the safest and most recommended option for daily hydration for the majority of people.

Simple and Effective Ways to Make Alkaline Water

Several methods exist for increasing the alkalinity of water at home, from using common household ingredients to investing in specialized equipment. The best method depends on budget, convenience, and how consistently one wants to consume alkaline water.

Using Baking Soda

Baking soda, or sodium bicarbonate, is a naturally alkaline substance with a pH of around 9.0. Adding a small amount to water is a simple and cost-effective way to increase its pH. Mix ⅛ teaspoon of baking soda into 8 ounces (1 cup) of filtered water. Stir until fully dissolved. Baking soda is high in sodium, so individuals watching their sodium intake should use this method sparingly.

Trying Alkaline pH Drops or Tablets

For a more controlled and convenient approach, alkaline mineral drops or tablets can be purchased from health food stores or online. These products are formulated specifically to raise the pH of water. Add the recommended number of drops to water and stir or shake. The mineral concentration provides a reliable way to achieve a higher pH, and the small bottles are portable for on-the-go use.

Investing in Alkaline Water Filters

For a long-term solution, an alkaline water filter pitcher or in-line filter system offers continuous access to alkalized water. These filters use cartridges that add beneficial alkaline minerals like calcium, magnesium, and potassium back into the water as it passes through. This not only raises the pH but can also improve the taste of the water. The initial investment is higher than other methods, it is often more cost-effective over time than buying bottled alkaline water.

The Misconception of Lemon Water

One widely circulated but misleading claim is that adding lemon juice to water makes it alkaline. A fresh lemon has an acidic pH of 2 to 3. However, adding lemon juice directly to water makes the water more acidic, not alkaline. Furthermore, the human body tightly regulates its own blood pH, and dietary changes have a minimal, if any, effect. The idea that lemon water can alkalize the body is largely considered a health myth.

Important Considerations and Risks

While making and drinking alkaline water is generally safe for most people, certain precautions should be taken. Using too much baking soda can lead to excessive sodium intake. Extreme pH levels, above 9.8, could potentially lead to conditions like metabolic alkalosis, especially for individuals with kidney disease.

Homemade vs. Commercial Alkaline Water

Feature Homemade Methods (Baking Soda, Drops) Commercial Filters & Ionizers
Cost Very low Moderate to High
Convenience Easy and quick to prepare per serving Effortless and continuous supply
Consistency Varies based on user measurements Highly consistent and controlled pH
Flavor May alter taste (e.g., salty from baking soda) Often improves taste by adding minerals
Mineral Content Dependent on the specific additive (e.g., sodium from baking soda) Often adds beneficial minerals like calcium and magnesium
Filtration Does not filter; requires pre-filtered water Combines filtration and remineralization

The Body's Natural pH Regulation

The body has a system for maintaining a stable blood pH between 7.35 and 7.45. The kidneys and lungs work together to regulate this balance, and external factors like food and drink have little to no impact on overall body pH. The primary effect of alkaline water is temporary and localized, such as neutralizing stomach acid, which can provide temporary relief from acid reflux, though more effective treatments exist. The long-term health benefits of alkaline water are not yet supported by strong scientific evidence.

Conclusion

Substances can be intentionally added to water to make it alkaline, using methods from baking soda to filtration systems. However, the premise that consuming alkaline water can dramatically alter body pH for health benefits is not well-supported by science. While some may find it helps with temporary issues like acid reflux, pure, filtered water is generally considered the best and safest choice for everyday hydration for most people. For those interested, experimenting with safe, controlled methods like pH drops or filtered pitchers is a viable option, but it is important to manage expectations regarding its effects on overall health. Ultimately, the choice to consume alkaline water should be informed, considering both the methods available and the scientific evidence.

Frequently Asked Questions

No, this is a myth based on a misunderstanding of metabolism. Lemon juice is highly acidic and will make water more acidic when added directly. While your body's metabolic process creates alkaline byproducts from lemon, it does not alter your body's overall pH, which is tightly regulated.

Yes, adding a small amount of baking soda to water is a safe and effective way to increase its pH. However, baking soda contains sodium, so individuals on low-sodium diets should monitor their intake. Use about ⅛ teaspoon per cup of water.

Some small studies suggest alkaline water may provide temporary relief for acid reflux symptoms by neutralizing stomach acid. However, this effect is temporary, and there is no scientific consensus that it is a long-term solution or better than standard medical treatments.

An alkaline pitcher uses filters to add minerals, like calcium and magnesium, to water to increase its pH. An ionizer uses electrolysis to separate acidic and alkaline water, a more advanced process that is generally more expensive.

You can purchase an inexpensive pH test kit, which usually includes test strips and a color chart, at a health store or online. This allows you to measure the pH of your tap water before and after adding alkalinizing agents.

Excessive consumption of strongly alkaline water (pH above 9.8) can potentially lead to metabolic alkalosis, mineral imbalances, or digestive issues. This risk is higher for people with pre-existing conditions like kidney disease. It is always wise to consult a doctor before making significant dietary changes.

No. Claims that alkaline water can prevent or treat cancer are not supported by scientific evidence. Your body has effective natural mechanisms to regulate blood pH, and dietary changes have a negligible impact.
