TOP ALKALINE BOTTLED WATER PICKS: Evamor and Icelandic Glacial Spring Water

Alkaline water and it’s proposed health benefits have become a hot topic over the past few years and many people are turning to bottled alkaline water to help balance the excess acidity associated with many Western diets and lifestyles.

This excess acidity in the body (known as acidosis) is increasingly associated with a range of health issues – from fatigue and headaches to skin conditions and digestive issues. Advocates of alkaline water believe it may help to balance this acidity, as well as increase detoxification and protect our cells from ageing.

This has led to a host of different brands of bottled alkaline water appearing on the market.

Below you’ll find a comparison table featuring 10 of the top brands.

What’s So PHenomenal About pH Anyway? A Quick Lesson!

To better understand which alkaline water brand to choose, it helps to understand the basics of pH.

Alkaline water is generally described as water with a pH higher than 7.0. A pH level can range from zero to 14, with 7 being neutral. Anything under 7 is considered acidic and anything over 7 alkaline.

Although it varies depending on where you live, most municipal tap water generally has a neutral pH of 7 or is slighty acidic (a pH less than 7). Many common brands of bottled water also tend to be on the acidic side.

Here’s a quick video from Qure Water which helps explains the pH Scale:

Alkaline bottled water brands such as Qure above, claim to offer drinking water with a pH over 7, which as we’ve seen, may be more beneficial to the body, especially an acidic one.

Not all alkaline bottled water is created the same though.

Whilst some bottled alkaline water is derived naturally from springs, other brands of alkaline water undergo processes such as ionization to increase the pH.

Let’s look briefly at the difference between the two.

Alkaline Spring Water Vs ‘Artificial’ Alkaline Water

Natural alkaline water, from sources such as springs, is water that’s passed through rocks and soil, where it picks up naturally alkalizing minerals, such as calcium, silica, potassium, magnesium and bicarbonate.

The body needs a constant supply of these alkalizing minerals in order to maintain it’s complex pH regulation system. The presence of these alkalising minerals produce what’s known as a ‘buffering effect’ and it’s this that helps neutralise excess acids, not a high pH alone.

‘Artificial’ alkaline water on the other hand is generally tap water that has been treated though a process such as ionization. Ionization has two affects on water – it makes the pH more alkaline and it alters the ORP (oxidation reduction potential) of water to a negative state.

Water with a -ORP is considered to have antioxidant (detoxyfying potential). The effectiveness of ionization, however, depends largely on the original quality of the water being ionized.

The Problem With Some Bottled Alkaline Water

A problem with alkaline bottled water that’s been engineered, (for example through ionisation), is that it can start to lose it’s pH and antioxidant potential pretty rapidly. The antioxidant (ORP) potential tends to go first, in as little as 24 hours, whilst the pH tends to drop in around 1-2 weeks.

So without testing the water yourself, it’s often impossible to know how alkaline the bottled water truly is by the time you drink it.

Which Alkaline Water Brand Should I Choose?

At the end of the day, it’s a personal choice. But if you choose to drink alkaline bottled water, our recommendation is to opt for an alkaline water brand that sources their water 100% naturally from a spring, as it’s likely to contain naturally alkalizing minerals, such as calcium and magnesium, which are essential to health.

A natural artesian spring water, such as Evamor, also doesn’t tend to lose its pH value in the way engineered water may do.

Our top choices for bottled alkaline spring water Evamor and Icelandic Glacial.

Both brands source their water directly from natural springs, offer a pH over 8, plus bottle the water at source, with nothing added and nothing removed. You can see Evamor’s lab reports here.

To avoid the potential of plastic toxins, it’s also an excellent idea to look for bottles they state they are BPA free.

A Cost Effective Alternative to Alkaline Bottled Water Brands

Many people choose to drink bottle alkaline water because it’s convenient and also because a fully blown alkaline water machine is costly and beyond many people’s budget.

So you might find that a good alternative to bottled alkaline water is an alkaline water filter pitcher.

Alkaline pitchers are very affordable and ensure a constant supply of fresh, alkaline drinking water, negating the need to buy it in bottles. Even with the cost of replacing the filter periodically, it’s likely you’ll save long term on the cost of bottled alkaline water brands. You also avoid the issue of your water losing pH or antioxidant potential over time, as with a pitcher, the water is alkalized on a daily basis.

Alkaline Bottled Water FAQS

Here are some more commonly asked questions with reagrds to alkaline bottled water.

Which Brand of Alkaline Bottled Water Has The Highest pH?

It’s hard to say for sure, as without testing the water at the point the bottle is opened, it’s impossible to know the exact pH of the water at the time of drinking. However, Alkalife and Qure both claim their bottled water has a pH of 10, which is among the highest of the different alkaline bottled water brands on the market.

Qure also claim to use a curing process, which ensures the stability of the pH for up to 2 years in its sealed bottle. Alkalife also state on their website that their Alkalife Ten water will retain it’s pH for a minimum of 2 years.

Can You Drink Too Much Bottled Alkaline Water?

As with anything, balance is key. Drinking too much alkaline water may deplete stomach acids to low levels and drinking a lot of water, with a high pH, may also disrupt the body’s pH balance. If unsure or you have a medical condition, always consult a health/medical professional first.

What Are The Benefits of Drinking Alkaline Water?

There are many potential health benefits associated with drinking alkaline water. These include helping to balance the pH system, aiding with skin conditions, such as psoriasis and excema, as well as improving the digestive and immune system and soothing acid reflux.

How Can I Test The pH Of Bottled Water Myself?

If you want to test the pH of bottled, or any other type of water, it’s recommended you use a pH Reagent or a pH meter as an indicator of pH value. People often use pH strips to measure water pH, but these are designed more for use with saliva or urine and considered unreliable for water readings.

What Does Science Say About Alkaline Water?

There is a lot of anecdotal evidence on the health benefits of alkaline water. Holistic approaches to health, such as Ayurveda and Chinese Medicine have also long promoted the importance of maintaining an alkaline balance in the body.

Modern scientific evidence, however, is more limited. This can lead to much debate and sometimes misinformation on the subject. Qure Water offer a helpful summary of much of this research if you wan to delve into this area further.

Best Brands of Alkaline Water – A Final Word

Alkaline water may have a number of key health benefits.

However, keep in mind the pH of bottled alkaline water that’s been engineered generally starts to drop within 1-2 weeks. The antioxidant potential (ORP) drops even quicker.

So if you wish to drink bottled alkaline water, research suggests water sourced from a natural spring probably has the most potential health benefits, since the water will have undergone natural alkalization from natural minerals in rocks and soil. A natural alkaline water brand such as Evamor is a good choice.

Alternatively, you may want to consider an alkaline water filter pitcher. They’re affordable and offer you a fresh supply of alkaline water on a daily basis, which you can easily decant to your own personal water bottle for ‘on the go’.
