How to Make Alkaline Water?

Struggling with complex or pricey alkaline water options? It’s frustrating! Good news: you can easily make natural, low-cost alkaline water right in your kitchen, and I’ll show you how.

You can make alkaline water by adding simple ingredients like baking soda or lemon juice to regular water. Using a water ionizer machine or special alkaline water filters are other common methods available.

So, those are the basic ways. But you probably want to know the details, especially how to do it safely and effectively at home without spending a fortune. Let’s dive into the specifics and explore the popular methods people are talking about.

How do you make alkaline water at home?

Thinking about making alkaline water at home? Maybe you’re concerned about safety or the high cost of specialized machines you see online. Luckily, simple, reliable, and very affordable DIY methods are easily available.

The easiest ways I’ve found to make alkaline water at home involve adding a small pinch of baking soda¹ or a squeeze of fresh lemon juice to your water. You can easily check the pH using test strips.

Making alkaline water at home doesn’t have to be complicated or break the bank. Many people, myself included, started exploring this out of curiosity or a desire for potential health benefits without investing heavily upfront. There are a few popular routes you can take, each with its pros and cons.

The Baking Soda Method

This is probably the simplest way.

• How: Just add a tiny amount of baking soda (sodium bicarbonate) – about 1/8th teaspoon to a large glass (8 ounces) of water – and stir until it dissolves.
• Pros: It’s incredibly cheap, readily available, and definitely increases the water’s pH quickly.
• Cons: The taste isn’t great for everyone. More importantly, baking soda is high in sodium. If you’re watching your sodium intake due to high blood pressure or other health reasons, this method isn’t ideal for regular use. I tried it for a while but found I needed to be careful about the amount.
• Tools: Just baking soda, water, and maybe pH test strips² if you want to verify.

The Lemon Juice Method

This one sounds counterintuitive, right? Lemon juice is acidic!

• How: Squeeze about 1/8th to 1/4th of a lemon into a glass of water.
• The Twist: While acidic initially, proponents believe that after your body metabolizes the lemon juice, it has an alkalizing effect on your system. The water itself doesn’t become highly alkaline immediately.
• Pros: It’s natural, adds a fresh taste, and provides Vitamin C³.
• Cons: It doesn’t significantly raise the water’s pH in the glass. The alkalizing effect⁴ is metabolic and debated in scientific circles.
• Tools: Lemons, water.

Comparing Home Methods vs. Machines

Feature	Baking Soda Method5	Lemon Juice Method	Water Ionizer Machine	Alkaline Filter Pitcher
Cost	Very Low	Low	High	Moderate
Ease of Use	Very Easy	Very Easy	Easy (once set up)	Easy
pH Change	High (immediate)	Minimal (in glass)	High (adjustable)	Moderate
Added Benefit	None (adds sodium)	Vitamin C3	Often adds minerals	Often adds minerals
Potential Issue	High Sodium	Metabolic effect debated	Cost, Maintenance	Filter replacement cost

Ultimately, starting with baking soda (sparingly) or lemon water are easy entry points. If you decide you want consistently higher pH water, then looking into filters or machines might be the next step, but try the simple ways first.

Does lemon water make water alkaline?

Does adding acidic lemon juice somehow make your water alkaline? It sounds confusing, almost contradictory, doesn’t it? But the surprising answer lies not in the glass, but in how your body actually processes the lemon.

Lemon juice itself is acidic (low pH). However, once your body metabolizes it, proponents claim it produces alkaline byproducts⁶, potentially helping to balance your body’s overall pH. It doesn’t make the water highly alkaline.

This is one of the most common questions I hear, and it took me a while to wrap my head around it too. The key is understanding the difference between the food’s pH before you consume it and its effect after digestion and metabolism.

The Science Bit: Metabolism Matters

Foods are often categorized as acid-forming or alkaline-forming⁷ based on the residue they leave behind after your body breaks them down.

• Acidic taste ≠ Acid-forming: Lemons and other citrus fruits taste acidic due to citric acid. However, during metabolism, citric acid is used up in the Krebs cycle (our body’s energy production process).
• Alkaline Minerals: Lemons also contain minerals like potassium and magnesium. When the citric acid is metabolized, these alkaline minerals⁸ are left, contributing to an overall alkaline load or alkaline ash. This is thought to help buffer acidity in the body, particularly showing up as increased urine pH. I remember reading a study suggesting citric acid consumption could lead to less acidic urine, which supports this idea.

Lemon Water pH: In the Glass vs. In the Body

So, when you add lemon juice to water:

• In the Glass: The pH of the water will drop slightly, becoming more acidic because you’ve added an acid. If you test it with pH strips⁹, it won’t show an alkaline reading.
• In the Body: After drinking it, your digestive system and metabolic processes take over. The citric acid¹⁰ is converted to energy, and the remaining minerals exert an alkaline effect¹¹ within your system.

It’s crucial to understand this distinction. You aren’t drinking high-pH water when you drink lemon water. You’re consuming something that may help promote alkalinity internally through metabolic processes. It’s a more indirect effect compared to drinking water that is already alkaline (like from an ionizer or with baking soda). Think of it less as changing the water, and more as providing ingredients your body uses to maintain its balance.

Is alkaline water just water with baking soda?

Wondering if that expensive bottled alkaline water, or the water from fancy machines, is just tap water with a bit of baking soda mixed in? It feels like maybe companies are just hyping up something simple. Baking soda is one way, but it’s definitely not the whole story.

No, alkaline water¹² isn’t just water with baking soda. While adding baking soda does raise water’s pH temporarily and cheaply, other methods like water ionizers¹³ use electrolysis to change water structure and add minerals, offering potentially different effects.

It’s easy to be skeptical, especially with all the marketing buzz around alkaline water. When I first looked into it, I had the same question. Let’s break down the differences because simply adding baking soda is quite distinct from other methods, particularly water ionization.

Baking Soda: The Quick pH Fix

Adding sodium bicarbonate¹⁴ (baking soda) is a chemical method.

• Mechanism: It directly dissolves in water, releasing bicarbonate ions which are alkaline and raise the water’s pH.
• Effect: It’s a temporary boost. The underlying water structure isn’t fundamentally changed beyond the addition of sodium and bicarbonate.
• Key Concern: As mentioned before, the big drawback is the added sodium. Regular consumption can significantly increase your daily sodium intake, which is a health concern for many, especially those managing blood pressure. I personally avoid relying on this method for that reason.

Water Ionizers: Electrolysis in Action

These machines work differently.

• Mechanism: They use electrolysis. Water passes over charged plates (electrodes). This process splits water molecules (H2O) into acidic ions (H+) and alkaline ions (OH-). It also concentrates alkaline minerals¹⁵ already present in the tap water (like calcium, magnesium) into the alkaline stream.
• Effect: This produces water with a higher pH and potentially a negative Oxidation-Reduction Potential (ORP)¹⁶, which proponents claim has antioxidant effects. The change is more structural, not just additive.
• Key Concern: The main barrier here is cost. Ionizers can be expensive, ranging from hundreds to thousands of dollars. They also require proper maintenance.

Other Methods Matter Too

Beyond these two, you also have alkaline water filters (pitchers or under-sink systems) that typically use mineral cartridges to add alkaline minerals¹⁵ (like calcium, magnesium, potassium) and raise pH, often while filtering contaminants.

Here’s a quick comparison:

Method	Primary Mechanism	Key Added Substance	Main Pro	Main Con
Baking Soda	Chemical Addition	Sodium Bicarbonate	Cheap, Fast	High Sodium, Taste
Water Ionizer	Electrolysis17	Concentrated Minerals	High pH, Neg ORP	Very Expensive
Alkaline Filter	Mineral Addition	Alkaline Minerals	Filters + Alkalizes	Filter Cost, Variable pH

So, while baking soda can make water alkaline, it’s a specific method with significant drawbacks (sodium). True ionized alkaline water or filtered alkaline water are produced differently and don’t rely on adding baking soda.

Does adding Himalayan salt to water make it alkaline?

You’ve probably seen the wellness trend: adding a pinch of pink Himalayan salt¹⁸ to your morning water. It looks pretty, and people claim various benefits. But does this trendy mix actually make your water significantly alkaline? The answer is a bit more nuanced.

Adding Himalayan salt to water generally has a minimal effect on its pH, meaning it doesn’t make it significantly alkaline. Its main contribution is adding trace minerals¹⁹ and electrolytes, not drastically changing the water’s alkalinity.

I remember trying the Himalayan salt trend myself, curious about the hype. While it adds a slightly different taste and the idea of extra minerals is appealing, I didn’t notice a significant alkaline shift when I tested the pH. Here’s a deeper look.

Salt and pH: A Tiny Bump, If Any

• Neutral Salt: Pure sodium chloride (table salt) is a neutral salt. Dissolving it in pure water doesn’t really change the pH.
• Himalayan Salt Minerals: Himalayan salt isn’t pure sodium chloride; it contains dozens of trace minerals. Some of these minerals might have a very slight alkalizing effect depending on their form and the starting water’s chemistry, but it’s generally considered negligible compared to methods like adding baking soda or using an ionizer. The amount of salt you’d need to add to make a meaningful pH difference would likely make the water unpalatable and excessively high in sodium.

The Real Benefit: Minerals and Electrolytes

The more recognized benefit of adding Himalayan salt (or other mineral-rich salts like Celtic sea salt) to water is hydration support through electrolytes.

• Electrolytes: Salt provides sodium and chloride, key electrolytes. The trace minerals in Himalayan salt (like potassium, magnesium, calcium, though in small amounts) also contribute.
• Hydration: Electrolytes help your body regulate fluid balance and nerve function. Adding a small pinch of salt to water can sometimes help with hydration, especially after sweating heavily or if you’re drinking highly purified water (like reverse osmosis) that lacks minerals.
• Taste: Some people simply prefer the taste.

Combining for Effect?

If you enjoy the mineral aspect but still want a more noticeable alkaline boost, you could combine a pinch of Himalayan salt with other methods. For instance:

• Add salt and a squeeze of lemon (for the metabolic alkaline effect + minerals).
• Use filtered alkaline water and add a pinch of salt for extra electrolytes.
  I’ve sometimes added a tiny pinch to my lemon water in the morning.

So, while Himalayan salt water is popular for its potential mineral and electrolyte benefits, don’t rely on it as your primary method for making water alkaline. Its effect on pH is minimal at best. Think of it more as a mineral supplement for your water.

Who should not drink alkaline water?

Is alkaline water good for absolutely everyone? You might be wondering if there are any potential downsides or if certain people should perhaps avoid it. For most healthy individuals, it’s generally considered safe, but there are specific groups who should be cautious or steer clear.

People with kidney problems²⁰, those with low stomach acid²¹ (hypochlorhydria), or individuals taking certain medications that are affected by stomach pH should avoid alkaline water or consult their doctor before drinking it regularly.

Safety should always come first when trying something new related to health. While proponents highlight benefits, it’s crucial to consider potential contraindications. Based on medical advice and research I’ve encountered, here are the main groups who need to be careful:

Kidney Concerns

• Why: Your kidneys play a vital role in regulating your body’s pH balance and managing minerals. If you have chronic kidney disease or impaired kidney function, your kidneys might struggle to process the excess minerals or handle the pH load from consistently drinking highly alkaline water.
• Recommendation: Definitely talk to your doctor or nephrologist before considering alkaline water if you have any kidney issues.

Stomach Acid Issues

• Why: Your stomach relies on a highly acidic environment (low pH) to properly digest food (especially proteins) and kill ingested bacteria or pathogens. Regularly drinking highly alkaline water, especially around mealtimes, could potentially neutralize stomach acid.
• Conditions: People with conditions causing low stomach acid (hypochlorhydria or achlorhydria) should be particularly cautious. Temporarily neutralizing stomach acid might worsen digestion and nutrient absorption. I personally try to avoid drinking it right before or during meals for this reason.
• Recommendation: If you have digestive issues or known low stomach acid, consult your doctor.

Medication Interactions

• Why: The absorption of certain medications depends on the acidic environment of the stomach. Altering stomach pH with alkaline water could potentially interfere with how these drugs are absorbed and how effective they are.
• Recommendation: If you are taking any prescription medications, especially those for stomach conditions or drugs known to have pH-dependent absorption²², discuss alkaline water use with your doctor or pharmacist.

General Precautions

Even for healthy individuals, moderation is key.

• pH Level: Drinking water with an extremely high pH (e.g., above 10) isn’t generally recommended. Most commercially available alkaline waters are in the 8-9.5 pH range.
• Listen to Your Body: Pay attention to how you feel. If you experience any digestive upset or other unusual symptoms after starting alkaline water, stop drinking it and consult a healthcare professional.

The bottom line is: alkaline water isn’t a magic bullet, and it’s not suitable for everyone. When in doubt, especially if you have pre-existing health conditions, always prioritize professional medical advice.

Conclusion

Making alkaline water at home is definitely possible using simple methods like baking soda or lemon, but it’s important to understand the differences, potential drawbacks like sodium, and who should avoid it.
