If you’ve heard of quinoa, juice detox, or coffee enema, then this is probably not the first time you come across the concept of alkaline water.

How To Make Alkaline Water

With a new diet trend spun out and fading almost every other year, it can be challenging to decide if alkaline water is a fad, or actually a healthy regimen to maintain in the long term. Perhaps if the latter is the case, you’d be interested in learning how to make alkaline water. That way, you won’t have to spend ridiculous money buying premium bottled water.

Hence the exploration we will make today.

What’s Alkaline Water?

The alkalinity of water, as well as that of many other liquids, is determined by the pH (potential of hydrogen) level. The higher the pH, the more alkaline or basic a liquid is, and vice versa.

The pH level of normal drinking water is usually seven. Alkaline water has a higher pH than seven, usually somewhere between eight and nine.

Alkaline water may come from springs or artesian wells in areas where there is a large amount of dissolved minerals. You can also produce it using very simple methods. Among which, the most effective is using a commercial or residential water ionizer. It’s worth noting, however, that there are claims that the water quality is not on par with that of alkaline water from natural sources.

Benefits and Risks of Alkaline Water Consumption

Like the case with other health trends, there is a debate around the benefits and risks associated with consuming alkaline water.

Alkaline Water Benefits

The hype of drinking alkaline water stems, as far as we know, from the acid-ash hypothesis of osteoporosis.

Benefit of Alkaline Water

As the hypothesis goes, foods that turn into acidic ash after burning in the metabolic process can make blood more acidic. This causes osteoporosis, a condition where our bones become weakened, fragile, and more prone to breaking. A high acidity also leads to faster aging and nourishes cancer cells, according to advocates.

This is the root of the alkaline diet, a diet consisting mostly of foods that, when burned, produce ash that has a basic pH. Followers of this diet believe it can improve your health and skin condition, slow down the aging process, and reduce the risk of cancer. Alkaline water is a widely accepted part of this diet.

The claimed benefits of alkaline water include:

  • Hydration
  • Easing digestion, as it softens your stool
  • Improving skin health
  • Aiding weight loss by increasing satiety and boosting your metabolism
  • Detoxing, as it helps flush out acidic waste in your system
  • Anti-aging
  • Balancing your blood pH
  • Preventing cancer, allegedly thanks to its ability to neutralize harmful free radicals

You may have noticed that most of these benefits are associated with staying hydrated by drinking normal water. That said, we have found some studies that suggest alkaline water may be the superior choice in certain cases.

In a study published in the Journal of the International Society of Sports Nutrition in 2016, Weidman et al. found that alkaline water was more effective than neutral water in reducing blood viscosity after exercise. Viscosity is, in layman’s term, the thickness and stickiness of blood. High viscosity is associated with increased risks of heart disease and stroke.

In a study in 2012, Koufman and Johnston suggested that pH 8.8 water might help with acid reflux. They found that the water denatured the agent pepsin, a digestive enzyme that adheres to and causes damage on laryngeal cells when someone has acid reflux. The alkaline water also acted as a buffer against stomach acid, which helps with the flux symptoms.

Those are small-scale studies, and more evidence would be necessary before we can confirm the benefits of high pH water. The good news is, if it may not be beneficial, alkaline water is likely safe to drink.

Of course, the overconsumption of it does come with side effects.

Risks From a High Alkalinity

The chances are slim, but metabolic alkalosis may occur if you drink too much alkaline water and take in an excessive amount of bicarbonate. Alkalosis can cause hand tremors, muscle twitching, and mild nausea. In more serious cases, it can lead to shock or coma. Luckily, it is extremely unlikely that one would drink enough alkaline water to get to this point.

When discussing the negative effects of basic water, overhydration is also a possibility. Overhydration, which may lead to confusion and seizures, happens when you drink too much of any liquid and your body doesn’t have enough time to get rid of it. This, again, is also not very common. As an adult with normal, healthy kidneys, you would have to drink more than six gallons a day before you can over-hydrate yourself.

Another possible non-healthwise side effect of drinking alkaline water is the overspending on bottled water. This, however, is reversible. There are many ways you can produce your own high pH water for drinking without bleeding the wallet.

How to Make Alkaline Water

Here are the six common ways you can turn your tap water into high pH water.

1. Baking Soda

Baking soda

With a pH level of 9, adding baking soda is one of the most popular ways to alkalize your drinking water.

The Canadian Society of Intestinal Research (CSIR) recommends 1/2 teaspoon of baking soda mixed in "at least 125 ml" (4 fluid ounces) of water for temporary relief from heartburn symptoms. For healthy adults, a popular recipe is ⅛ tablespoon (or 1/3 teaspoon) of baking soda in 8 fluid ounces of purified water. Stir or shake the mixture thoroughly so that the baking soda becomes completely dissolved, and you got your alkaline water ready for drinking.

Note, though, that baking soda may have side effects if consumed at large amounts. Also, baking soda is high in sodium. You may not like the taste of it in your water. More importantly, if you’re sensitive to sodium or are on a special diet that needs cutting down of salt, the benefits may not be worth the risks to try this method.

2. Lemon Juice

Lemon

This may sound counterintuitive, but lemon juice is part of an alkaline diet. The juice, while highly acidic (typically having a pH of 2 or 3), is claimed to produce basic byproducts when metabolized. It was, in fact, found that lemon juice can increase urine pH. However, science has yet to confirm the real impact this juice has on your blood pH or the claimed alkalinity-related health benefits of this drink.

If you’d like to try this method, the good news is, diluted lemon juice is safe (and tasty) to drink. If anything, it’ll add some vitamin C, and a tart scent and taste to your drink. The aesthetic effects are similar to when you add lemon slices into your water jug.

Similar to the baking soda recipe, you can add ⅛ tablespoon of lemon juice in 8 fluid ounces of clean water. You may want to juice the lemons beforehand, and store the juice in the fridge for future use.

3. pH Drops

PH-drops

The use of pH drops is on the rise, as drinking alkaline water becomes a trend.

pH drops are liquids with highly concentrated minerals and electrolytes. You only need to add a couple drops to each glass of water to increase its pH. The liquids usually come in small handy bottles so you can carry them everywhere with you. One single bottle can improve the pH of hundreds of glasses of water. This makes these dops a favored choice compared to lemon juice or baking soda.

You can find the most popular pH drops here.

4. Water Filter Pitcher

A water filter pitcher

A water filter pitcher is a jug with a water filtration function. The water you fill it with passes through some layer of filtration materials. Depending on the type of filter used, it can come out slightly alkalized. Note that not every pitcher filter can make high pH water.

The alkalization is rather only a byproduct. The main function of filter pitchers is to reduce the amount of chlorine and other impurities in the water. They can significantly improve the water smell and taste. They are also very affordable. The problem with them is that it takes a little while for the water to go through the filter cartridge. You have to wait a few minutes before the filtered water is available. Filter pitchers are thus not an ideal option for large households.

5. Water Filtration System

A water filtration system

Household water filters not only remove various pollutants and contaminants like fluoride, chlorine and toxic heavy metals. Some of them are designed to make the water more alkaline.

Simple filters like multi-stage faucet-mount filters may include mineral balls among the layers of filtration materials for this purpose. On more advanced and complicated systems, this happens during remineralization. During this stage, a small amount of calcium and magnesium is released into the water to slightly increase the pH. This stage is popular on systems such as the under sink filter or the whole house filtration system, especially those of the reverse osmosis type.

6. Water Ionizer

The most efficient way to make alkaline water at home is to use a water ionizer/electrolyzer.

This type of machine works by taking advantage of the electrolysis phenomenon. It separates the negative and positive electrodes in the water. The machine returns two streams of water: alkaline in one stream, and acidic in the other.

The ionizer is highly effective in producing basic water. The icing on the cake is that it does so without introducing any substances into it. Beware, however, that some can be a little over-effective. They can the pH to up to 12, which might be a tad too high for drinking.

Compared to buying bottled water, ionizing machines are the more affordable option money-wise in the long term. They also reduce the need for plastic bottles, and are thus better for the environment. Unfortunately, this type of machine can be cost-prohibitive upfront to most people. They typically have a price tag of more than $1500 each.
