In recent years, alkaline water has gained significant attention as a trendy health drink, with proponents claiming it offers unique health benefits that regular drinking water does not. This article will explore the differences between alkaline water and regular drinking water, examining the scientific evidence behind the health claims, potential benefits, and considerations for consumers thinking about incorporating alkaline water into their daily routines.

What is Alkaline Water?

Alkaline water is characterized by its higher pH level compared to regular drinking water. While regular water typically has a neutral pH of around 7, alkaline water boasts a pH of about 8 or 9. This increased pH level is the result of adding minerals like calcium, potassium, sodium, and magnesium, which raise the water’s overall alkalinity.

How is Alkaline Water Produced?

  • Water Ionizers: These devices are attached to a home’s water supply where they use a process called electrolysis to split water molecules into acidic and alkaline components. The alkaline part is then siphoned off to be consumed.
  • Additives: Alkaline water can also be created by adding alkaline minerals directly to the water.
  • Natural Sources: Some natural waters are inherently alkaline due to the minerals they acquire from their environment.

Health Claims of Alkaline Water

Proponents of alkaline water believe it offers multiple health benefits, including:

  • Acid Reduction in the Body: It is thought that alkaline water can neutralize excess acid in the body, helping to prevent diseases related to acidosis.
  • Antioxidant Properties: Some claim that alkaline water can act as an antioxidant, seeking out and neutralizing harmful radicals in the body.
  • Enhanced Hydration: Due to its smaller molecular content, advocates suggest that alkaline water is more easily absorbed by your body, which improves hydration.
  • Bone Health: There is some evidence suggesting that consuming alkaline water may help to preserve bone density and mitigate bone resorption.

Scientific Evidence and Skepticism

Despite these claims, the scientific community remains skeptical about the purported health benefits of drinking alkaline water. Most peer-reviewed studies have found little concrete evidence that drinking alkaline water provides health benefits beyond those of normal water. Here are a few key points from the research:

  • Digestive Function: The highly acidic environment in the stomach neutralizes the alkalinity of the water, negating its alkaline properties once ingested.
  • Bone Health Claims: While some studies have suggested that alkaline water might aid in decreasing bone resorption, these studies are not sufficient to confirm a direct beneficial link to overall bone health.
  • Antioxidant Benefits: There is limited scientific backing for the claim that alkaline water acts as an antioxidant.

Practical Considerations

For most people, drinking regular water is sufficient for staying healthy and hydrated. However, for those considering trying alkaline water, there are a few practical aspects to keep in mind:

  • Cost: Alkaline water is typically more expensive than tap or filtered water.
  • Equipment: Installing a water ionizer at home can be costly and requires regular maintenance.
  • Taste: Some people may find the taste of alkaline water to be different or more palatable, which could encourage them to drink more water overall.


While the idea of drinking alkaline water can be appealing due to its supposed health benefits, there is limited scientific evidence to support many of the health claims. For the average person, drinking regular, clean water is still the best choice for hydration. That being said, if individuals find that drinking alkaline water helps them consume more water or if they prefer the taste, it may be a worthwhile personal choice. As always, consumers should approach health trends with caution and be informed about the scientific support behind any health product.
