How Does Alkaline Water Affect Your Body’s pH Levels?

Alkaline water has gotten a lot of attention in recent years, particularly among health enthusiasts and individuals who are towards enhancing their overall good health and lifestyle. However, what actually alkaline water is, and how does it affect the pH levels of the human body? In this blog, we’ll learn about the science behind alkaline water, its effects in the body’s pH balance, and if it truly offers the health advantages that many enthusiasts claim.

Understanding Alkaline Water

Alkaline water is characterized by a pH level that is always higher than that of ordinary potable water. i.e 7. The pH scale is neutral, with a range of 0 to 14. Anything with a pH value below 7 is categorized as acidic, while a pH value above 7 is classified as alkaline. Typically, alkaline water is produced by natural processes (such as mineral springs) or artificial processes (such as ionization) and has a pH of 8 or 9.

Natural vs. Artificial Alkaline Water

Natural Alkaline Water: This form of water is derived from natural springs or wells, where it is exposed to minerals such as calcium, magnesium, and potassium, which increase its alkalinity.

Artificial Alkaline Water: Created through a process called the electrolysis process or the ionization artificial alkaline water has undergone treatment to increase its pH level. This procedure involves processing the water through an ionizer, which uses electricity to separate the water into acidic and alkaline components.

The Concept of pH Balance in the Body

The pH balance of the human body is meticulously maintained, with blood pH being slightly alkaline, with a range of 7.35 to 7.45. The maintenance of this equilibrium is essential for the proper functioning of cells and your overall health. The body utilizes a variety of mechanisms, such as the kidneys, lungs, and buffer systems, to control and sustain this pH balance.

Diet and pH Balance

Your diet can influence the pH of your urine, but it has little effect on the blood’s pH level. Foods and beverages are categorized as acid-forming or alkaline-forming based on the residue they leave in the body after digestion and metabolism.

  • Acid-Forming Foods: Meat, eggs, dairy, and processed foods.
  • Alkaline-Forming Foods: Fruits, nuts, vegetables and seeds.

How Alkaline Water Affects Your Body’s pH Levels

The science behind drinking alkaline water is that it can help neutralize acid in the body, promoting a more alkaline state and thus better for  health. Here’s how alkaline water can potentially impact various parts of body:

Digestive System

When we consume alkaline water, it first interacts with your stomach, which is highly acidic (with a pH around 1.5 to 3.5) due to the presence of hydrochloric acid. This acidity is essential for digestion and killing harmful bacteria. Some experts argue that the stomach’s acid neutralizes the alkalinity of the water, rendering it ineffective in altering the body’s overall pH balance. However, others believe that the bicarbonate ions in alkaline water can help buffer stomach acid, potentially easing symptoms of acid reflux.

Blood pH

One of the most debated topics is whether alkaline water can affect blood pH. The body has powerful regulatory systems to maintain blood pH within a narrow range. Any significant change in blood pH can be life-threatening. While drinking alkaline water might have a minor temporary effect on blood pH, the body’s homeostatic mechanisms quickly restore balance.

Urinary pH

Drinking alkaline water can influence the pH of your urine, making it more alkaline. This is because the kidneys filter excess minerals and bicarbonate, which are then excreted in the urine. Monitoring urine pH can give an indication of the body’s acid-alkaline balance, but it doesn’t necessarily reflect the blood’s pH.

Bone Health

There is some evidence suggesting that a more alkaline diet can help prevent bone loss. The theory is that when the body is too acidic, it may leach minerals like calcium from the bones to neutralize the acid. By consuming alkaline water and maintaining an alkaline diet, you might reduce this effect and support bone health. However, more research is needed to confirm these benefits.

Potential Health Benefits of Alkaline Water

While scientific evidence is still limited, proponents of alkaline water claim several potential health benefits:


Some studies suggest that alkaline water can enhance hydration, especially after strenuous exercise. The theory is that alkaline water is more easily absorbed by the body, leading to better hydration.

Antioxidant Properties

Alkaline water is believed to have antioxidant properties, helping to neutralize free radicals that cause cellular damage and contribute to aging and disease.

Acid Reflux Relief

As mentioned earlier, alkaline water may help neutralize stomach acid, providing relief from symptoms of acid reflux.


Alkaline water may aid in detoxifying the body by neutralizing acidic waste products and promoting their excretion through urine.


The effect of alkaline water on the body’s pH levels is a complex and somewhat controversial topic. While drinking alkaline water may offer some health benefits, such as improved hydration and potential relief from acid reflux, its impact on overall pH balance and other claimed benefits require more scientific validation.

It’s important to approach the consumption of alkaline water with a balanced perspective. Maintaining a healthy diet rich in fruits and vegetables, staying hydrated, and following a healthy lifestyle are the cornerstones of good health. As with any health trend, it’s advisable to consult with a healthcare professional before making significant changes to your diet or wellness routine.

Whether you choose to drink alkaline water or not, understanding how it interacts with your body can help you make informed decisions about your health and wellness journey.
