How much lemon juice to make water alkaline?

6 min read

The pH of raw lemon juice is between 2 and 3, making it highly acidic, yet many people believe it can make water alkaline. This article explores the truth behind this popular wellness claim and answers the question: how much lemon juice to make water alkaline.

Quick Summary

Lemon water's alkaline effects occur after metabolism, not by changing the water's initial pH. A small amount of lemon juice is used to create this refreshing drink.

Key Points

  • Metabolic Magic: The 'alkalizing' effect of lemon water occurs in your body after metabolism, not by changing the water's pH in the glass.

  • Small Amount Needed: For the metabolic effect, the juice of half a lemon in a glass is sufficient and common.

  • Protect Your Teeth: Use a straw and rinse your mouth with plain water to protect tooth enamel from the acidic lemon juice.

  • Immediate Alkalinity: For truly alkaline water from the start, use a pinch of baking soda, specialized filters, or a water ionizer.

  • Hydration is Key: The primary benefits of lemon water are hydration and Vitamin C, regardless of its effect on your body's pH.

  • Metabolism Matters: Your body, specifically your kidneys and lungs, tightly regulates your blood's pH, not your diet.

Understanding the Lemon Water Myth

Before discussing how much lemon juice to add, it's crucial to understand the scientific principle behind the 'alkaline' claim. On the pH scale, a reading below 7.0 is acidic, while above 7.0 is alkaline. Pure water has a neutral pH of 7.0. Lemon juice, which contains citric acid, has a pH of approximately 2-3, making it strongly acidic. Adding lemon juice to plain water will inevitably lower the water's initial pH, making the liquid more acidic, not alkaline.

The misconception arises from the metabolic process that occurs after the lemon water is consumed. When your body digests and metabolizes the lemon's citric acid, it produces alkaline-forming byproducts, primarily potassium carbonate. These byproducts can influence the acidity of your urine, but they do not alter the pH of your blood, which is tightly regulated by the body's buffer systems. Drinking lemon water is a great way to hydrate and get a dose of Vitamin C, but it will not magically turn the liquid in your glass alkaline.

The Correct Ratios for an 'Alkalizing' Effect

Since the goal isn't to change the water's immediate pH but to consume an alkalizing food, the amount of lemon juice is more about taste and personal preference than a specific, pH-changing quantity. A simple and popular method is to use the juice of half a lemon in a glass of water.

For a 1-liter pitcher of water, many recommend using about 2 tablespoons of fresh lemon juice. It is important to use filtered, purified, or reverse osmosis water rather than tap water to start with a clean slate, as tap water's pH can vary based on your location. To enhance the flavor and potential alkalizing effect, you can also add other natural ingredients. Popular additions include cucumber slices, fresh mint, or a pinch of sea salt. Allowing the mixture to sit for 30 minutes can help the flavors meld.

Protecting Your Tooth Enamel

One of the main drawbacks of regularly consuming acidic beverages, even diluted ones like lemon water, is the risk of damaging tooth enamel. To mitigate this risk, consider the following steps:

  • Drink your lemon water through a straw to minimize contact with your teeth.
  • Rinse your mouth with plain water immediately after finishing your drink.
  • Wait at least 30 minutes before brushing your teeth, as brushing immediately after consuming acidic food can further harm softened enamel.

Other Ways to Create Truly Alkaline Water

If your primary goal is to drink water with a higher pH, there are more effective and immediate methods than relying on lemon's metabolic effect. These methods can instantly raise the pH of water and provide a consistently alkaline beverage.

Comparison Table: Methods for Making Alkaline Water

Method How It Works Benefits Drawbacks
Lemon Juice Creates alkaline byproducts after being metabolized by the body. Natural, refreshing flavor, provides Vitamin C. Does not make the water itself alkaline, can damage tooth enamel.
Baking Soda Dissolves sodium bicarbonate directly into water, instantly raising the pH. Instantly and reliably increases pH, inexpensive. Can have a slightly salty taste, should be used in moderation due to sodium intake.
Water Filters Ionizes or adds minerals to the water as it passes through the filter. Purifies water, reliably increases pH, consistent results. Initial investment cost, requires filter replacement.
Water Ionizers Uses electrolysis to separate water into alkaline and acidic streams. Precise control over pH level, includes built-in filtration. Significant upfront investment, can be expensive.

A Simple Recipe for 'Alkalizing' Lemon Water

Creating your own lemon water is a straightforward process. Here is a simple recipe to get you started:

  1. Wash and rinse a fresh, organic lemon thoroughly.
  2. Fill a glass or pitcher with 8-12 ounces of filtered water.
  3. Cut the lemon in half and squeeze the juice from one half into the water, using a strainer to catch any seeds.
  4. For extra flavor, add a few slices of the other half of the lemon to the water.
  5. Stir the mixture gently.
  6. Let it infuse for a few minutes before drinking, or refrigerate for 2-4 hours for a more robust flavor.

This simple preparation method provides a healthy and refreshing drink. For those wanting a true pH boost, the addition of a very small amount of baking soda (about 1/4 tsp per glass) can instantly raise the pH, but do so carefully and observe how your body responds.

Conclusion: The Final Verdict on Lemon Water's Alkalinity

In summary, the notion that you can simply add a large quantity of lemon juice to water to make it alkaline is a myth based on a misunderstanding of chemistry. While the lemon water mixture remains acidic outside the body, its metabolic byproducts are alkaline-forming, which can affect the pH of your urine but not your blood. The amount of lemon juice to use is more a matter of taste and personal preference, with the juice of half a lemon per glass being a common recommendation. For those with a specific goal of consuming alkaline water, other methods like using baking soda or specialized filters are more direct and reliable. Regardless of its pH-shifting properties, drinking lemon water remains a fantastic way to stay hydrated and enjoy a boost of flavor and Vitamin C. Just remember to protect your teeth from the initial acidity.
