The concept of “naturally ionized water” refers to increasing the water’s alkalinity, measured by its pH level, and enriching it with beneficial minerals. This is a simple, cost-effective way to achieve a higher pH without using expensive electric ionizer machines. Many people are interested in do-it-yourself methods to raise the pH of their drinking water to a mildly alkaline level, typically between 8 and 9. These methods focus on introducing alkaline-forming compounds or minerals directly into the water supply to shift the chemical balance toward alkalinity.
Understanding Water Alkalinity vs. Ionization
While “ionized water” is often used interchangeably with “alkaline water,” they represent two different chemical processes. Alkalinity measures the water’s capacity to neutralize acids, determined by dissolved alkaline minerals like calcium, magnesium, and bicarbonate. Raising the water’s pH above 7 makes it alkaline. Commercial electric water ionizers use electrolysis to split water molecules, separating the water into acidic and alkaline streams. This process creates water with a negative Oxidation-Reduction Potential (ORP) and dissolved hydrogen, which is scientifically considered true ionization. The natural, at-home methods discussed here focus solely on mineral addition to achieve a measurable increase in alkalinity and mineral content.
Direct Mineral Addition Methods
One of the most immediate and predictable ways to create alkaline water is by adding pure mineral compounds directly into the liquid. These methods allow for a precise and measurable shift in the water’s pH balance.
Baking Soda
Sodium bicarbonate, commonly known as baking soda, is a highly alkaline compound with a pH of around 9. Dissolve approximately one-quarter of a teaspoon of baking soda into one liter of filtered water. This addition can raise the water’s pH to a mildly alkaline range, often around 8.5, but requires thorough stirring. Individuals monitoring sodium intake should exercise caution, as this method increases the water’s sodium content.
Alkaline Mineral Drops
Alkaline mineral drops offer a highly concentrated source of electrolytes, including calcium, magnesium, and potassium. These liquid concentrates are designed to rapidly raise the pH of water with just a few drops. The exact dosage should follow the product label, but typically, five to ten drops are sufficient to alkalize one liter of water. These drops are convenient for travel and remineralize water stripped by purification systems like reverse osmosis.
Himalayan Pink Salt
A small pinch of Himalayan pink salt can introduce trace minerals into the water. This salt contains trace elements that act as electrolytes, contributing to the water’s overall mineral profile. While the amount needed to significantly shift the pH is negligible, adding about one-eighth of a teaspoon to a liter of water provides subtle remineralization.
Fruit and Vegetable Infusion Techniques
Infusing water with certain fruits and vegetables is a gentle method for creating an alkalizing beverage. This process relies on the metabolic effect of the produce’s mineral content after consumption, rather than directly changing the water’s pH.
Citrus fruits like lemons and limes are acidic outside the body, but they have an alkalizing effect once metabolized. The minerals they contain, such as potassium and magnesium, are released during digestion and create alkaline byproducts. This process reduces the body’s potential renal acid load, contributing to an overall alkaline environment.
To prepare infused water, slice half a lemon and a lime, placing the pieces into one liter of water. Allow the fruit to infuse at room temperature for at least eight to twelve hours so the minerals and flavor compounds leach into the water. Adding a few slices of cucumber can further enhance the mineral content and provide a refreshing taste.
Monitoring pH and Safety Guidelines
Before regularly consuming homemade alkaline water, monitor its pH level to ensure it falls within a safe range. Use inexpensive pH test strips or a digital pH meter to check the water after using natural methods. Regulating bodies recommend that drinking water generally remain between a pH of 6.5 and 8.5 for palatability and safety.
While water with a pH up to 9.5 is usually considered safe, avoid concentrations above this level, as highly alkaline water can develop a bitter taste. Excessive alkalinity may also lead to minor gastrointestinal issues, such as constipation or mild upset stomach. Moderation is recommended to prevent the risk of mineral overload from water too rich in added minerals.
Individuals with pre-existing medical conditions, particularly kidney disease, should consult a healthcare professional before making significant changes to their drinking water’s pH. Those taking medications like proton pump inhibitors for acid reflux should also seek medical advice, as alkaline water could potentially interfere with drugs that alter stomach acidity.
