Mineral water is one of the most popular beverages worldwide and is preferred by many as a natural and healthy source of drinking water. However, little attention is paid to purification and disinfection processes. One of the most common disinfection methods in the mineral water industry is ozone (O₃). Although this method is highly effective against bacteria, long-term consumption of ozonated mineral water can have negative effects on human health. In this article, we examine the dangers of ozone in mineral water and provide scientific recommendations for safe consumption.
1. What is ozone and why is it used in mineral water?
Ozone is a triatomic oxygen molecule that is considered a highly effective water disinfectant due to its strong oxidizing properties. Many mineral water companies use ozone to kill bacteria, viruses, and other microorganisms for the following reasons:
-
It leaves fewer harmful chemical residues in the water than chlorine.
-
It works quickly and requires less time for cleaning.
-
The taste and smell of the water change less.
However, these benefits should not lead us to ignore the potential harms.
2. The oxidizing effect of ozone on the human body
Ozone is a strong oxidizing agent, meaning it can oxidize compounds with which it comes into contact. When drinking ozone-enriched mineral water, small amounts of ozone can react with organic compounds in the body to form oxidation products. These include:
-
Cell and tissue damage: The resulting free radicals can damage the body’s cells and accelerate the premature aging process.
-
Increased risk of inflammation: Chronic exposure to oxidants can lead to chronic inflammation in body tissues and contribute to the development of heart disease, diabetes, and liver problems.
-
Weakened immune system: Long-term use of antioxidants can reduce the body’s ability to fight infections.
3. Effects on the digestive system
One of the main concerns surrounding ionized water is its effect on the digestive system. Studies have shown that regular consumption of ionized water can:
-
It can irritate the stomach lining and cause problems such as heartburn, upset stomach, and gastritis.
-
It reduces the amount of beneficial intestinal bacteria (normal intestinal flora) and changes the balance of intestinal microorganisms .
-
Long-term use may increase the risk of chronic gastrointestinal diseases such as irritable bowel syndrome.
4. Effects on the respiratory and cardiac systems
Although drinking ozonated water is not directly linked to respiratory diseases, its oxidation products can indirectly affect respiratory and heart health:
-
Oxidants can increase vascular inflammation and raise blood pressure.
-
Studies have shown that oxidants can damage vascular endothelial cells and thus increase the risk of atherosclerosis and heart disease.
-
People with respiratory or heart diseases should avoid long-term consumption of ozone-enriched water.

5. The impact of ozone use on the environment
The widespread use of ozone in mineral water has not only an impact on personal health but also on the environment:
-
Industrial ozone production consumes large amounts of energy and increases a company’s carbon footprint.
-
Byproducts of ozone oxidation can be released into the environment and affect the quality of natural water resources.
-
The use of plastic bottles in ozonated mineral water and their mixing with oxidation products leads to additional problems of chemical contamination.
6. Tips for drinking mineral water safely
Despite the potential dangers, drinking spring water is sometimes necessary, especially in areas where purified tap water is unsafe. To reduce the risk, consider the following:
-
Diversify your water sources: It is better not to limit yourself to mineral water, but also to drink healthy, clean, homemade or boiled and cooled water.
-
Check the label: Some brands indicate the amount of ozone remaining in the water. It’s recommended to choose a brand with controlled ozone levels.
-
Limit your water intake: It is better to drink oxygenated water temporarily and in limited amounts than to rely on it as your main daily water source.
-
Proper storage: Ozone is highly unstable and can produce harmful byproducts in plastic bottles. Therefore, avoid storing water at high temperatures for extended periods.
7. Conclusion
Ozone in mineral water is an effective disinfectant and antimicrobial agent, but long-term use can have negative effects on human health. Its oxidative effects on cells , the digestive and cardiovascular systems, and the environment are significant. By taking precautions and limiting use, you can avoid potential harm and ensure the consumption of safe, high-quality mineral water.
Ultimately, consumer awareness and careful research into water treatment methods and ozone levels are crucial for making informed decisions and maintaining good health. While mineral water may seem healthy and natural, understanding the chemical processes that go into its production can significantly improve your quality of life.
