The 10 Best Alkaline Water On The Market of 2025, Tested and Reviewed

The healthiest alkaline water is one that not only has a high pH but is also free from contaminants and contains beneficial minerals. Brands like Essentia and Fiji are often recommended due to their rigorous purification processes and high pH levels. Essentia, for instance, has a pH of 9.5 and is noted for its purity and mineral content. Fiji water, sourced from natural springs, also provides a high pH and essential minerals. For the healthiest option, look for water that is filtered and tested to ensure it meets safety and quality standards.

What Water Has the Highest Alkaline?

When it comes to commercially available water, those with the highest alkaline pH levels often range between 9.0 and 10.0. Essentia water is well-known for its high pH of 9.5. Other brands like Alkaline88 offer water with a pH of 9.0. Some home water ionization systems can produce water with a pH as high as 10.0, but these systems are typically more expensive and require regular maintenance. Natural sources, like certain mineral springs, can also offer high pH levels, but they are less commonly found in bottled form.

What is the Best Homemade Alkaline Water?

To make homemade alkaline water, you can use a variety of methods:

1. Water Ionizers: These devices are installed in your home and use electrolysis to increase the water’s pH. They can produce water with a pH of 8.5 to 10.0. Brands like Kangen and Tyent are popular in this category.

2. Alkaline Water Filters: These filters, which can be attached to your faucet or used in pitcher form, add minerals like calcium and magnesium to increase the pH. Products from brands like Brita and ZeroWater offer options for enhancing your water’s alkalinity.

3. Additives: You can also add a pinch of baking soda (sodium bicarbonate) or lemon juice to water to raise its pH. However, this method is less precise and might not be as effective or safe for daily use.

Is 9.5 Alkaline Water Better for You?

Water with a pH of 9.5, such as Essentia, is often considered better for those seeking a more pronounced alkaline effect. It may help neutralize acidity in the body more effectively compared to water with a lower pH. Some proponents believe it can aid in digestion, reduce acid reflux, and enhance hydration. However, scientific research supporting these benefits is still ongoing. While many people find 9.5 pH water beneficial, it's essential to consume it in moderation and consult with a healthcare provider if you have any health concerns.

Who Should Not Drink Alkaline Water?

Alkaline water may not be suitable for everyone. People with the following conditions should be cautious:

• Kidney Issues: Individuals with kidney disease or those on dialysis should consult their healthcare provider, as excessive alkaline water can impact kidney function.
• Metabolic Conditions: People with metabolic alkalosis or similar conditions should avoid excessive intake of alkaline water, as it can worsen their condition.
• Certain Medications: Some medications may interact with changes in body pH, so it’s wise to check with a healthcare provider if you are on medication.
• Pregnant or Breastfeeding Women: While generally safe, pregnant or breastfeeding women should consult their healthcare provider to ensure it aligns with their nutritional needs.
