Alkaline water has a potential hydrogen (pH) level above 7, typically ranging from 8 to 9.5, in contrast to neutral tap water, which is generally a pH of 7. This higher pH is achieved through dissolved alkaline minerals like calcium, magnesium, and potassium. The appeal of consuming alkaline water stems from the belief that it can help neutralize excess acidity in the body. Naturally occurring alkaline water acquires its pH from flowing over mineral-rich rocks, while homemade versions rely on simple additives to increase the pH level. These do-it-yourself methods offer an accessible way to create water with higher alkalinity.
Alkalizing Water Using Baking Soda
Baking soda (sodium bicarbonate) is a highly alkaline substance that provides a direct way to increase the pH of water. It has a high pH, typically around 8.3 to 9.0, making it an effective agent for raising alkalinity. The process involves dissolving a small, measured amount of the powder into water.
To prepare alkaline water, mix about one-eighth to one-quarter teaspoon of baking soda into one liter of clean, filtered water. Stir or shake the mixture thoroughly until the baking soda is completely dissolved. This addition works by chemically neutralizing acidity and introducing alkaline ions.
The resulting water will have a slightly salty taste due to the sodium content. Individuals on a low-sodium diet should be mindful of the added sodium from this method. This technique easily achieves the target consumption pH, generally between 8.0 and 9.5.
Alkalizing Water Using Citrus Fruits
Alkalizing water with citrus fruits, such as lemons or limes, is a popular method that works differently than direct chemical addition. Although the fruits are acidic due to their citric acid content, they contain alkaline-forming minerals like potassium, calcium, and magnesium. These minerals contribute to the alkalizing effect.
Once the fruit’s organic acids and minerals are metabolized by the body, they leave behind an alkaline residue. This metabolic process creates the net alkalizing effect on the body’s internal environment, rather than changing the water’s pH before consumption. This method is considered milder than using baking soda.
To infuse the water, slice a whole lemon or lime and add the slices to a pitcher of water. Allow the fruit to soak for at least eight hours, or overnight, so the minerals can infuse. This long soaking time facilitates the release of the fruit’s components, providing a subtle, flavorful, and mineral-rich option.
Testing and Safe Consumption Practices
Measuring pH at Home
Testing the pH of your homemade alkaline water is important to ensure it falls within the safe and desired range. The most accessible methods for home testing involve using either liquid pH reagent drops or pH test strips. pH strips are small pieces of paper impregnated with a dye that changes color when dipped into the water, indicating the pH level.
To use the strips, dip one end into the water sample for a few seconds, then compare the color change to the manufacturer’s chart. For a more precise measurement, liquid pH drops, often used for pools or aquariums, are added directly to the water sample. The water’s color then changes, and you match it against a color-coded chart to determine the pH.
A digital pH meter can also be used for the most accurate reading, though these tend to be more expensive. Testing before consistent consumption is advisable to confirm the alkalinity is not too high, as a pH above 9.5 can sometimes lead to an overly bitter taste. The water is safe to drink if it registers a pH between 8.0 and 9.5.
Safe Consumption Guidelines
Alkaline water is generally safe for most people, but practicing moderation is beneficial. Excessive intake of highly alkaline water may upset the stomach or interfere with the body’s natural digestive acidity. The goal is to avoid disrupting the body’s tightly regulated natural pH balance.
Individuals with pre-existing kidney conditions should consult a healthcare professional before drinking alkaline water regularly. The kidneys are primarily responsible for regulating the acid-base balance, and consuming high-pH water could potentially increase their workload. Those taking medications, especially proton pump inhibitors for acid reflux, should also discuss consumption with a doctor, as alkaline water may affect drug absorption.
For storage, using glass containers is preferable to plastic, especially for long-term storage, to avoid the potential leaching of plastic compounds. Generally, a daily intake matching typical hydration guidelines, around 64 to 80 ounces, is considered safe for most healthy adults, provided the pH is maintained within the optimal 8.0 to 9.5 range. Listening to your body and stopping consumption if any discomfort occurs is the simplest guideline to follow.
