Ozonated water is essentially water that has undergone treatment with ozone gas, a process that has garnered attention for its potential health benefits. Advocates assert that ozonated water can provide various advantages in both clinical and industrial applications, ranging from its ability to help prevent cancer and combat free radicals in the body to enhancing dental health and ensuring food safety. However, it is important to note that recent research on this subject is somewhat limited, making it challenging to fully assess the numerous claims associated with ozonated water.

This article delves into the existing evidence surrounding ozonated water, exploring its production methods, various uses, potential benefits, and possible drawbacks.

What is Ozonated Water?

Ozone is a colorless, odorless gas made up of three oxygen atoms. In its gaseous state, ozone is an unstable molecule that can potentially harm the lungs if inhaled. However, when ozone is infused into water, it transforms into ozonated water, which is believed to possess a range of therapeutic benefits. These benefits may include antioxidant and antimicrobial properties, making it a popular choice in dental therapy, cancer treatment, and various food safety practices.

Despite the promising claims surrounding ozonated water, it's important to note that many of the studies conducted on this topic are outdated, highlighting the necessity for more contemporary research to validate these effects. The therapeutic potential of ozonated water extends from combatting cancer to enhancing food preservation, making it an intriguing subject for further exploration.

How it’s Made

Creating ozonated water is a straightforward process that involves filling a cylinder with purified water while ozone gas is continuously bubbled through it. This method should be sustained for a minimum of five minutes to achieve optimal saturation levels, ensuring that the ozone gas dissolves completely into the water. The result is a solution that is not only effective but also safer to handle compared to ozone in its gaseous state.

It’s important to note that while ozone in its gaseous form can pose risks to the respiratory system, ozonated water is a much more manageable alternative. This water has potential applications in both industrial settings and therapeutic initiatives, making it a versatile option for various uses.

Advantages of Ozonated Water

In the last twenty years, a multitude of studies have explored the health benefits associated with ozonated water, revealing intriguing possibilities.

Below are several notable advantages of incorporating ozonated water into your routine.

Cancer Treatment and Prevention

Treating cancer is often a challenging journey. Traditional therapies, such as chemotherapy and radiation, may not always effectively target tumors. Research from the early 2000s indicates that ozonated water might improve the effectiveness of chemotherapy drugs against tumors. However, it's important to note that these findings stemmed from animal studies and have yet to be validated in human trials.

Another investigation from the same period examined the incidence of bladder cancer among adults who consumed ozonated water compared to those who drank chlorinated water. Both methods aim to disinfect water and eliminate harmful bacteria and microbes. The results suggested that individuals drinking ozonated water had a reduced risk of developing bladder cancer. Nevertheless, further long-term studies are essential to substantiate these findings.

Dental Treatment

Recent studies suggest that ozone may serve as a viable treatment option in dentistry. Its applications include eliminating harmful bacteria in the mouth and promoting the healing of oral injuries. In one study focusing on the impact of ozonated water on tooth decay, researchers compared it to a chlorhexidine mouth rinse. The trial included 23 adults, with salivary samples collected at intervals of 7 and 14 days of consistent ozonated water use. The findings revealed a substantial reduction in Mutans Streptococci, a bacterium linked to an increased risk of cavities. Additionally, another study indicated that using ozonated water on oral wounds accelerated the healing process by enhancing cell turnover.

Antioxidant and Antimicrobial Effects

Ozone is classified as an oxidant, which means it can form free radicals and potentially harm cells within the body. Exposure to ozone gas can induce a stress response, prompting the body to produce various antioxidants that help eliminate free radicals.

A case study involving a 62-year-old woman highlighted the benefits of ozonated water, in conjunction with antibiotics, for treating a urinary tract infection (UTI). The ozonated water was introduced into the urinary tract three times over a week. The patient successfully recovered from the UTI, and no reinfection occurred during the four-month follow-up period. However, more comprehensive research is necessary, as this study focused on a single individual who was also undergoing antibiotic treatment.

Furthermore, ozonated water may expedite the cell repair process, diminish bacterial presence, and alleviate symptoms associated with urinary tract infections. In addition to its antioxidant capabilities, ozonated water may also enhance the efficacy of antibiotics against certain microbes.

Food Safety and Water Purification

The antibacterial characteristics of ozone, along with its ability to eliminate industrial contaminants, have rendered it a promising alternative to chlorine.

In 1901, cities in Germany and France became pioneers in using ozone for drinking water purification. Today, over 3,000 cities worldwide employ ozone for the same purpose. In 1995, the United States Food and Drug Administration (FDA) classified ozone as “generally recognized as safe” for use with bottled water and contact with food. According to both historical and contemporary studies, ozonated water can effectively wash fresh produce, significantly reducing surface bacteria and extending shelf life. However, its application should occur within controlled environments.

Potential Downsides

Ozone gas is widely recognized as a pollutant, leading to an inflammatory response that can inflict damage on the airways upon inhalation. Even brief exposure has been shown to intensify respiratory symptoms in both adults and children. Furthermore, some older research indicates that ozone exposure during the second or third trimester may be linked to low birth weight. However, it is essential to note that additional contemporary studies are required to substantiate this theory and to fully comprehend the underlying mechanisms involved.

Most investigations have primarily focused on the effects of ozone gas instead of those associated with ozonated water. At present, there appears to be a lack of research connecting ozonated water to respiratory issues or low birth weights. While ozone gas poses certain risks if not managed by a qualified professional, the full extent of these risks remains unclear.

On a more positive note, ozonated water is known for its antibacterial and antioxidant-promoting qualities. When handled appropriately, it may offer several health benefits, including the prevention of tooth decay, reduction of bladder cancer risk, purification of drinking water, and enhanced efficacy of cancer treatments.

The Bottom Line

Although ozone gas can present certain health risks, the use of ozonated water reveals significant therapeutic potential. The FDA acknowledges that ozonated water is safe for drinking and for food contact. In controlled environments such as industrial water treatment facilities or under medical supervision, there is evidence suggesting that ozonated water can be safe for consumption and may play a role in specifi
