Discovering the Best Alkaline Water

In the quest for optimal health, alkaline water has emerged as a key player. A product that once seemed niche, it’s now gaining widespread popularity. But what exactly makes the best alkaline water? Let’s dive in and find out.

Understanding Alkaline Water

Alkaline water is not your everyday tap water. It has a higher pH level, typically around 8 or 9, compared to regular water, which is generally around 7.

This high pH level can neutralize acid in your body. Some people believe this can provide various health benefits, from boosting energy to slowing aging. However, more research is needed to validate these claims.

The Benefits of Alkaline Water

Alkaline water is not only refreshing to drink but also comes with numerous health benefits. These include:

  • Balancing the body’s pH levels: Regular consumption of alkaline water can help neutralize acid in your body, thereby maintaining optimal pH levels.
  • Hydration: Alkaline water is believed to be more hydrating than regular water. This is particularly beneficial for individuals who work out regularly and require more water to stay hydrated.
  • Detoxification: Alkaline water can aid in the detoxification process, helping your body to cleanse itself of toxins more effectively.
  • Immunity Boost: By neutralizing harmful free radicals and boosting the immune system, alkaline water can help keep you healthier and less prone to disease.
  • Anti-aging properties: Alkaline water is rich in potent antioxidants that help to slow down the aging process by counteracting oxidative damage to cells.

Criteria for the Best Alkaline Water

Identifying the best alkaline water isn’t as simple as picking up the first bottle you see. Here are some key factors you should consider:

pH Level

The pH level is the first thing to look at. The optimal level is typically between 8 and 9.5. Anything above this may be too alkaline and can cause side effects.


The source of the water is also essential. Natural spring water is often considered the best source of alkaline water.


Finally, check for any additives. The best alkaline water should be free from artificial sweeteners, colors, and flavors.

Top Alkaline Water Brands

While there are many brands on the market, here are some that consistently rank among the best:

Health Benefits of Alkaline Water

Alkaline water is often praised for a range of health benefits it provides. Supporters of alkaline water highlight several potential advantages:

  • Improved Hydration: Alkaline water, particularly those with added electrolytes like Essentia Water, can enhance hydration. This is especially beneficial for athletes or those who engage in high-intensity workouts, where efficient hydration is crucial.
  • Neutralizing Body Acidity: Some proponents argue that a diet high in acidic foods can lead to a variety of health issues. Alkaline water, with its higher pH level, may help neutralize the acid in your body.
  • Supporting Bone Health: Some studies suggest that alkaline water may support bone health. It’s believed to aid in the reduction of bone resorption, the process where old bone cells are broken down and replaced by new ones.

Please consult with your healthcare provider before making any changes to your diet, including adding alkaline water.

Scientific Research and Studies

The popularity of alkaline water has sparked interest and research into its health benefits. However, the scientific community’s consensus is not entirely established.

While some studies suggest potential health benefits such as improved bone health, many experts believe more comprehensive research is needed. There are also conflicting views on whether the body’s natural mechanisms for managing pH levels render alkaline water’s effect negligible.

It’s crucial for consumers to approach health claims about alkaline water critically and to rely on reputable sources of information.

How to Choose an Alkaline Water Brand

When selecting an alkaline water brand, several factors should be considered:

  • pH Level: Look for brands that provide the pH level on their labeling. The higher the pH, the more alkaline the water.
  • Source: Consider where the water comes from. Brands like Icelandic Glacial source their water from natural springs, which some consumers prefer.
  • Purification Process: Understand the purification process the brand uses. For instance, Smart Water uses a vapor distillation method, while ZenWTR undergoes an 8-step purifying process.
  • Company Values: If environmental sustainability and corporate responsibility are important to you, choose brands that prioritize these values. For example, ZenWTR is known for using recycled plastic bottles, and Icelandic Glacial operates a sustainable facility.

DIY Alkaline Water

If you prefer a hands-on approach or wish to save money, making alkaline water at home can be an option. Here are a few methods:

  • Baking Soda: Adding a small amount of baking soda to a glass of water can increase its alkalinity. However, remember that baking soda is high in sodium, so this may not be a suitable option for everyone, especially those monitoring their sodium intake.
  • Water Ionizer: Water ionizers are machines that use electrolysis to increase the pH of water. The water is separated into acidic and alkaline components—the alkaline water is then ready for drinking.

Again, it’s important to consult with a healthcare provider before making significant changes to your water consumption habits.

Environmental Impact of Alkaline Water

The environmental impact of bottled water, including alkaline water, is a significant concern for many consumers. Here’s how some of the top alkaline water brands are addressing this issue:

  • Essentia Water: Owned by Nestle, this brand has demonstrated a commitment to environmental initiatives, donating more than $1.5 million to humanitarian and environmental causes. However, like all bottled water companies, the environmental impact of their plastic bottle production and distribution is a factor to consider.
  • ZenWTR: This brand stands out for its commitment to environmental sustainability. ZenWTR uses 100% recycled ocean-bound plastic for its bottles. In fact, every bottle of ZenWTR is made from up to 5 recycled ocean-bound plastic bottles. The company aims to rescue 50 million pounds of ocean-bound plastic by 2025. They also claim to have reduced their energy use by 84% and greenhouse gases by 71% per pound of plastic, compared to using virgin plastic.
  • Smart Water: As a product of Coca-Cola, Smart Water is part of a company with wide-reaching environmental initiatives. However, specific information about Smart Water’s environmental impact or sustainability efforts is not readily available.
  • Icelandic Glacial: Icelandic Glacial is an entirely carbon-neutral company. The brand operates a sustainable facility that runs on geothermal and hydroelectric power. To offset any other emissions formed in production or shipping, the company invests in forestry, renewable energy, and global conservation projects.

While these brands have made strides toward sustainability, it’s important to remember that bottled water still has a significant environmental footprint. Opting for reusable water bottles and home filtration systems can be a more eco-friendly choice. As consumers, we can make a difference by making informed choices and advocating for more sustainable practices.


When it comes to choosing the best alkaline water, the decision ultimately comes down to personal preference and your specific health needs. Whether you choose a top-rated brand or opt to make your own at home, always remember to stay properly hydrated and consult with a health professional if you have any concerns.

Remember, it’s not just about drinking water. It’s about making a conscious choice for better health and well-being.
