What is ORP? How does the ORP index in drinking water affect health?
1. What is the ORP index?
ORP (short for Oxidation Reduction Potential) is an index used to measure the oxidation level of a product in units of Millivolts (mV). In other words, ORP is a measure of the oxidation or reduction potential of a substance.
Metabolism occurs every minute, every second in the human body. This process is based on a chain of oxidation-reduction reactions and provides the necessary amount of energy through daily eating to maintain balance.
Therefore, when using food or drink, you need to know the ORP index to know whether you are taking oxidants or antioxidants into your body. The ORP index is a representation of the oxidation - reduction level of the product.
A positive ORP result indicates that a substance is oxidizing, and the higher the number, the more oxidizing it is. For example, a substance with an ORP reading of +500 mV is 5 times more oxidizing than a substance with an ORP reading of +100 mV.
Conversely, the lower the index, the more reducing and antioxidant properties the substance has. For example, a substance with an ORP of -500 mV has 5 times more antioxidant capacity than a substance with an ORP of -100 mV.
The ORP index tells us the oxidation level of a substance.
2. Meaning of ORP index
Positive value
A substance with a positive ORP index means that the substance has the ability to oxidize, if used regularly can cause the risk of forming and developing free radicals.
This is the reason why aging occurs rapidly and causes negative effects on health. The ORP indexes of commonly used soft drinks are: tap water (+200mV), bottled spring water (+200mV), carbonated soft drinks (+400mV).
Negative value
Conversely, a negative ORP index represents the reducing properties (antioxidant properties) of that substance. The lower the ORP of a substance, the higher its antioxidant capacity. Examples of some drinks and foods with negative ORP that are recommended for use include: olive oil (-200mV), green tea (-100mV), vitamin C (-100mV), alkaline ionized water (between -300mV and -800mV),...
The rate of people suffering from diabetes, cardiovascular disease, blood pressure, neurological diseases, etc. is increasing due to unhealthy diets and environmental pollution. Therefore, using foods with negative ORP index can help slow down the aging process, increase resistance, and prevent diseases.

3. The role of ORP index in drinking water
This index is used to evaluate the oxidation level of ingredients in food, drinking water and even in the human body. Therefore, the role of the ORP index in drinking water is very important, it is one of the indexes that users need to pay attention to, especially when investing in water purifier products at home.
3.1. Assessment of drinking water quality
Through the ORP index, customers can evaluate the quality of the water source they are using:
- Clean drinking water: Has an ORP value ranging from +200 to +600 mV. For example, water containing chlorine has a high ORP because chlorine is a strong oxidizer. Research conducted by the US Centers for Disease Control and Prevention (CDC) shows that water with a high ORP value from chlorine can kill most disease-causing bacteria and viruses within minutes.
- Alkaline ionized water source: Has a negative ORP index, from -200 to -400 mV, indicating that alkaline ionized water has strong reducing properties. According to a 2020 study on the Benefits of Alkaline Ionized Water for Human Health , alkaline ionized water can neutralize free radicals, help protect cells from damage, and help people prevent dangerous disease symptoms.
Alkaline ionized water has a deep negative ORP level, chosen by many customers for family use.
3.2. Determining domestic biosafety
A high ORP level in clean water may indicate the presence of a disinfectant, such as ozone or chlorine. For example, a study by the American Chemical Society (ACS) found that water with an ORP above +650 mV has the same disinfection ability as traditional chemical methods. Customers can use this index to assess whether the water is safe to drink directly.
In addition, the World Health Organization (WHO) report recommends using the ORP index as a measure in measuring water quality management system standards, ensuring safe, direct drinking water.
From there, we can see that the ORP index plays an important role and has great significance in assessing the quality of drinking water and human health.
4. What ORP index is good for health?
The reality of environmental pollution, ultraviolet interference, dirty food intake, etc. is increasingly serious. This causes the human body to produce many free radicals, creating negative impacts on health such as: dry skin, lack of vitality, cancer, cardiovascular disease, etc. Therefore, WHO - World Health Organization recommends that users should use foods and drinks with negative ORP index which are good for health, not exceeding the threshold of -500mV .
About food
Customers can find negative ORP index within the standard range in some foods such as: Brown rice, blueberries, cauliflower, dark chocolate, goji berries, barley,... These are all foods with high nutritional content, and are also a rich source of antioxidants.
Some foods rich in antioxidants
About drinking water
Water sources with negative ORP are rich in reducing properties and have the ability to donate electrons to neutralize free radicals, increasing the amount of oxygen that nourishes the body. Including alkaline ionized water - possessing only negative ORP and the ability to donate electrons, helping to neutralize free radicals and increase the amount of oxygen for the body. Created by electrolysis technology from an electrolysis machine, alkaline ionized water retains minerals. ultra-small, rich in OH- and Hydrogen gas, with a pH of 8.5 – 9.5.
With a low ORP index, superior to foods rich in vitamins C, A, E and 2.5 times higher antioxidant capacity than green tea, alkaline ionized water has been proven to neutralize free radicals, slow down the oxidation process, thereby helping to protect the body from diseases such as stress, fatigue, high blood pressure, cardiovascular disease, and metabolic disorders.
To create a source of alkaline ionized water to protect health and use daily in the family, customers can refer to Mutosi Hydrogen water purifier products manufactured using advanced Japanese technology, ensuring the quality of hydrogen water output is negative to -600mV.
Using Mutosi alkaline ionized water every day helps increase the body's resistance and reduce pathogens.
5. Factors affecting ORP index in water
The ORP index in water can be affected by factors such as:
1. pH: The relationship between pH and ORP is very close. The higher the pH (alkaline, pH value>8), the deeper the negative ORP index, indicating that the water has strong reducing properties. Conversely, low pH (acidic, pH value<7) is often accompanied by positive ORP. Experts recommend only using water sources with a pH between 7.0 - 9.5 to ensure body balance.
2. Temperature: As water and ambient temperature increase, ORP also tends to increase.
3. Light and air: Light and air affect the ORP index by changing the oxidation-reduction reaction and ionization properties of substances in water. The stronger the light intensity and the higher the humidity in the air, the more the ORP increases to a positive level.
4. Water treatment process: Water treatment methods such as chlorination, ozone or electrolysis can also affect the ORP index of water. Customers should use drinking water treated by electrolysis to ensure that the ORP index in water is maintained at the standard level.
To avoid the ORP index being affected by many external factors, customers should use Hydrogen water purifiers with advanced water filtration and storage systems, ensuring that appropriate output water indexes are maintained.
