Alkaline water, also known as ionized water, has gained popularity in recent years for its potential health benefits. However, some have raised concerns about the potential risks of drinking alkaline water, particularly with regard to kidney stones. In this article, we will explore the current evidence on does alkaline water cause kidney stones?
We will also examine the role of pH in kidney stone formation and the pros and cons of drinking alkaline water. The aim of this article is to provide a comprehensive overview of the topic and to help readers make informed decisions about their hydration habits.
Alkaline Water and Kidney Stones: The Evidence
- Alkaline water and kidney stones: the evidence. The relationship between alkaline water and kidney stones has been the subject of much debate and research in recent years. Some studies have suggested that drinking alkaline water may reduce the risk of kidney stone formation, while others have found no significant effect.
- Studies on Alkaline Water and Kidney Stones: Several studies have investigated the impact of alkaline water on kidney stone formation. One study published in the Journal of Renal Nutrition found that alkaline water with a pH of 8.8 reduced the formation of calcium oxalate crystals, which are a common cause of kidney stones. Another study published in the International Urology and Nephrology Journal found that drinking alkaline water with a pH of 9.5 increased the pH of urine and reduced the formation of calcium oxalate stones.

- What the Research Says: The research on alkaline water and kidney stones is somewhat mixed, with some studies showing a positive effect and others finding no significant effect. However, the majority of the research suggests that alkaline water may reduce the risk of kidney stone formation. This is thought to be due to the alkaline water’s ability to increase the pH of urine and reduce the formation of calcium oxalate crystals.
- Limitations of the Research: It’s important to note that most of the studies on alkaline water and kidney stones have been performed on animals or in a laboratory setting. More research is needed to confirm the findings in humans. Additionally, the studies that have been performed have had small sample sizes, making it difficult to draw definite conclusions.
In conclusion, the evidence on the relationship between alkaline water and kidney stones is mixed, but the majority of the research suggests that drinking alkaline water may reduce the risk of kidney stone formation. However, more research is needed to confirm these findings and to determine the optimal pH for reducing the risk of kidney stones.

Alkaline Water and Kidney Stone Formation
Alkaline water and kidney stone formation. Kidney stones are formed when substances in the urine, such as calcium, oxalate, and uric acid, form crystals that stick together and become stones. The formation of kidney stones is influenced by several factors, including the pH of urine.
- The Role of pH in Kidney Stones: The pH of urine plays a crucial role in the formation of kidney stones. Urine that is too acidic can lead to the formation of certain types of stones, such as uric acid stones. On the other hand, urine that is too alkaline can lead to the formation of other types of stones, such as calcium oxalate stones.
- How Alkaline Water Affects the pH of Urine: Alkaline water is water that has a higher pH than neutral water, with a pH of 7. Drinking alkaline water can increase the pH of urine, making it more alkaline. This change in pH can impact the formation of kidney stones by reducing the formation of calcium oxalate stones, which are more likely to form in an acidic environment.
- Other Factors that Contribute to Kidney Stone Formation: The formation of kidney stones is influenced by several factors, including genetics, diet, hydration, and certain medical conditions. For example, a diet high in salt, sugar, and animal protein can increase the risk of kidney stones, while a diet rich in fruits and vegetables can reduce the risk. Additionally, staying hydrated by drinking plenty of water is important for preventing kidney stones.
In conclusion, the pH of urine plays a crucial role in the formation of kidney stones, and drinking alkaline water can affect the pH of urine by making it more alkaline.
However, there are several other factors that contribute to kidney stone formation, and a balanced diet, adequate hydration, and regular check-ups with a healthcare provider can help reduce the risk of kidney stones.

The Pros and Cons of Drinking Alkaline Water
The pros and cons of drinking alkaline water are widely debated, with proponents claiming numerous health benefits and critics questioning the science behind these claims.
Pros of drinking alkaline water:
- Neutralizes Acid in the Body: Alkaline water has a high pH and is believed to neutralize the acid in the body, reducing inflammation and promoting a healthy pH balance.
- Improved Hydration: Alkaline water is often marketed as being better for hydration than regular water due to its smaller molecular size and ability to penetrate cells more easily.
- Antioxidant Properties: Some proponents claim that alkaline water has antioxidant properties that can help to neutralize harmful free radicals in the body.
- Better for Bone Health: Some studies have suggested that alkaline water may improve bone health by reducing the loss of calcium and other minerals.
Cons of drinking alkaline water:
- Lack of Scientific Evidence: Despite the numerous claims made about the health benefits of alkaline water, there is limited scientific evidence to support these claims.
- Cost: Alkaline water can be more expensive than regular water, making it less accessible for some people.
- Potential Side Effects: Drinking excessive amounts of alkaline water can lead to a condition known as alkalosis, which can cause a variety of symptoms such as nausea, muscle twitching, and confusion.
- No Impact on Overall Body pH: The body has a sophisticated system for regulating its pH, and drinking alkaline water will not have a significant impact on overall body pH.
While there are some potential benefits to drinking alkaline water, it is important to approach these claims with a critical eye and understand that the evidence is limited.
It is always a good idea to speak with a healthcare provider before making any significant changes to your diet or hydration habits.
Conclusion
In conclusion, the relationship between alkaline water and kidney stones is complex and not fully understood.
While drinking alkaline water may have some benefits, it is important to consider all of the factors that contribute to the formation of kidney stones, including diet, hydration, and genetics.
It is also important to understand that the scientific evidence supporting the health benefits of alkaline water is limited, and that more research is needed to fully understand the impact of this type of water on kidney stone formation and overall health.
As always, it is important to speak with a healthcare provider before making any significant changes to your diet or hydration habits.
