Kangen Water Health Benefits

Kangen water ionizers are in-home medical devices. The company was funded in Japan by Mr. Hironari Oshiro in 1974. The word Kangen means "return to origin" in Japanese. Machines are found in hundreds of hospitals in Japan, including Kyowa Hospital, Kitari Institute Medical Center, Showa University Hospital, Meiseki Hospital, Nara College of Medicine Hospital, Iida Hospital, Tokyo Women’s College of Medicine Hospital, Hanabatake Hospital, and many more. Over 6,500 doctors have tested Enagic’s Kangen Water life science devices in clinical applications with their patients.

Alkaline water containing molecular hydrogen is produced at the negative electrode (cathode). There are many names given to this water including: alkaline water, ionized water, alkali ion water, cathodic water,  electrolyzed reduced water (ERW), and more.

Electrolyzed reduced water (ERW) is the most common term in the scientific literature. It is called “electrolyzed” because the water has undergone electrolysis and is called “reduced” because the water at the cathode has been reduced to hydrogen gas and hydroxides. This alkaline water has reductive characteristics due to the presence of dissolved hydrogen gas.

Some of the biggest benefits of this water is the molecular hydrogen, antioxidants, anti inflammatory properties, and it's negative oxidation-reduction potential (ORP) between -100 mV to-700 mV.

Here is a brief introduction to Kangen water and it's uses. Kangen machines produce 7 different levels of custom pH water that can be used to replace all kinds of household products.

Kangen water is one of the higest sources of antioxidants

What are antioxidants? Let's start with oxidation. Oxidation is a chemical reaction that can produce free radicals, thereby leading to chain reactions that may damage the cells of organisms, and lead to aging. Think about when you bite into an apple, then leave it out for 10 minutes. It turns brown and softens very fast. The same thing happens with rust on iron when it is exposed to oxygen and moisture. This is the process of oxidation, and the same concept goes with our bodies aging.


So what are free radicals? Put simply, a healthy human cell has a negative and a positive charge (this as the harmonious balance of your cell). When the cell becomes unhealthy (due to oxidative stress), it looses it’s negative charge and becomes a free radical, and too many of these can lead to disease. Too many free radicals will lead to oxidative stress, which is linked to aging and a host of diseases. Reactive oxygen species (ROS) are a type of free radical that contains oxygen. A build up of reactive oxygen species (ROS) in cells may cause damage to DNA, RNA, and proteins, and may cause cell death. Numerous articles discuss the negative consequences of ROS and their implications on virtually every disease: Immune disorders, such as diabetes mellitus, multiple sclerosis, asthma, rheumatoid arthritis, chronic inflammation, and other fatal diseases such as cardiovascular disease, cancer, neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease as well as aging.

Antioxidants give their food/water/herbs a NEGATIVE electrical charge. These charges go into the body, and pair up with free radicals (which are positively charged), and NEUTRALIZE them. They are then able to be flushed out of our bodies. Antioxidants protect our cells from oxidative stress, and promote detoxification. So we want to get as many antioxidants as possible. Some foods high in antioxidants are blueberries, broccoli, spinach, oranges, garlic, green tea, bananas, acai berries. One glass of Kangen water is equal (in antioxidants) to 5 pounds of blueberries or 12 pounds of broccoli!!

Negative Oxidation-reduction Potential (ORP)

A negative oxidation-reduction potential (ORP or redox potential) reading indicates that a substance is a reducing agent. This is a measure of how well the water can reduce free radicals and protect against oxidative damage to cells. A liquid can either be positively charged (oxidizing) or negatively charged (reducing). Negatively charged water gives off electrons, neutralizing free radicals. This can prevent and even reverse cellular and tissue damage due to oxidative stress. The lower the reading, the more anti-oxidizing it is. As such, a substance with an ORP reading of -400 mV is 4 times more anti-oxidizing than a substance with an ORP reading of -100 mV. When the ORP value is high, there is lots of oxygen present in the water. Normal tap water, bottled water, and rain water have a positive ORP generally between 200 to 400 mV, and even as high as 500 to 600 mV depending on location.

This video shows a demonstration of an ORP test comparing some popular drinks and types of water. A negative ORP reading means the substance is less oxidizing (causes aging) and has more antioxidants.

This video shows how alkaline ionized water prevents rust from forming, compared to normal tap water, thus showing it's antioxidant properties.

Benefits of Molecular Hydrogen

Molecular hydrogen is the smallest molecule in the world, but don’t let its size fool you, molecular hydrogen (H2) has been studied as one of the most potent antioxidants available to us. Molecular hydrogen is able to both cross the blood-brain barrier and diffuse through cell membranes to influence the cytosol (fluid within cells), mitochondria (cell's energy powerhouse) and nucleus (“brain” of cells). This means we are able to feel true hydration as a result of drinking hydrogen-rich water because it rapidly penetrates bio-membranes and reaches sub-cellular compartments where it can exert its therapeutic benefits. It acts as an antioxidant and is thought to protect cells from oxidative stress-related damage. The correlative relationship between gut health and immune health grows more apparent as studies show the benefits of molecular hydrogen facilitating intestinal fermentation and gut health.

Medical research on hydrogen is still in its early stages with around 1000 articles, but these publications and researchers suggest that hydrogen has therapeutic potential in over 170 different human and animal disease models, and in essentially every organ of the human body. The therapeutic effect in cells, tissues, animals, humans and even plants is becoming widely accepted due to the now over 1,600 researchers on the medical effects of hydrogen.

The K8 (Kangen 8 machine) has 8 platinum coated titanium plates. These plates are larger and offer greater surface area that those of competitors, which means more room for ionization to occur, leading to more molecular hydrogen and a higher pH with less power applied.

PubMed study on molecular hydrogen therapy

Dixon and colleagues reported that hydrogen has potential to help with the top 8/10 disease-causing fatalities as listed by the Centers of Disease Control. The CDC describes the following as the top ten causes of death in America: cardiovascular disease, malignant neoplasms, chronic lower respiratory diseases, cerebrovascular diseases, accidents (unintentional injuries), Alzheimer’s disease, diabetes mellitus, influenza and pneumonia, nephritis (nephritic syndrome and nephrosis), and suicide (intentional harm). Interestingly enough hydrogen therapy can either be linked or speculated to be a potential treatment in each of those top causes of death, excluding deaths caused by accidents (unintentional injuries) and suicides (intentional harm)

11.5 Strong Kangen Water to Emulsify Pesticides

Most pesticides are oil based. They have to be pretty hardy or else they would just wash off anytime it rains. That means they also won't wash off with normal tap water.

11.5 strong Kangen water is able to emulsify oils. This will leave your produce tasting better and removing these harmful residues will actually increase the life of leafy greens and other veggies.

Note: Organic produce may still be grown with pesticides. The difference is these pesticides must be natural in origin, non synthetic. But that does not mean these are good for our health.

Strong Kangen 11.5 water can also be used as a de-greaser to clean surfaces such as the stove-top and oven, as well as floors and cutting boards. It can be used in place of laundry detergent and works as a great make-up remover.

Acidic Water Benefits

Electrochemically reduced water (ERW) is produced near a cathode and electrochemically oxidized water (EOW) is produced near an anode. EOW is also termed electrolyzed acidic water and is functional water exhibiting a sterilizing action, mainly due to hypochlorous acid, chlorine gas, and ozone. Acidic water is being used in hospitals and custodial services with a huge benefit being that it is non-polluting. When introduced into the environment, acidic water rapidly returns to its resting pH state. Acidic water is naturally free of phosphates and other pollutants that risk our environment and the future of our world.

Kangen's 2.5 acidic water is perfect for cleaning and disinfecting. Acidic water has a natural bleaching action. It can be used as hand sanitizer and even as mouth wash. It can replace many household cleaning products that contain different chemicals, while keeping your home clean and safe. It is also helpful in speeding up the healing of cold sores.

Anti-inflammatory Properties

Inflammation has been found as the root cause of most chronic disease. Some common factors that can cause inflammation are eating inflammatory foods (such as sugars, gluten, dairy, processed meats, fried foods, eggs, syrup and soft drinks, fast food), blood sugar imbalances, leaky gut syndrome, chronic stress, poor sleep habits, environmental toxins (such as pollution, personal care products, cleaning products, pesticides), and chronic infections. This can lead to diseases such as cancer, type 2 diabetes, stroke, heart disease, bowel diseases, Alzheimer's, asthma, arthritis, metabolic syndrome, etc.

The term anti-inflammatory is the property of a substance or treatment that reduces inflammation or swelling. Staying hydrated is essential to flushing inflammation-causing toxins out of your body. Kangen water is able to penetrate into cells and flush out toxins, making it a powerful anti-inflammatory agent. The molecular hydrogen has an important role to play in the prevention of chronic pain by neutralizing the free radicals (so they can be flushed out of our system), as well as in pain management through mitigation of inflammation and direct removal of reactive oxygen species.

Alkaline Ionized

Ionization means to gain or lose an electron. Water that has been ionized becomes either alkaline or acidic, meaning that the pH has been adjusted up or down. Many people have heard that we should be focused on eating an alkaline diet. This means more fruits, vegetables (whole foods) and less acidic foods (such as caffeine, alcohol, and sugar) in order to lose weight, have more energy, and ward off disease. An alkaline diet is also said to decrease inflammation. Now while all of this is true, and drinking alkaline water can help to offset some of the positive charge from eating acidic foods, the fact that Kangen water is alkaline is not it's top feature. The alkaline charge is merely a result of the negative oxidation-reduction potential (ORP). It can be beneficial to drink alkaline water when eating acidic food, or mix alkaline water with pineapple juice (acidic) to even out the negative affects, but once it gets to your stomach, the body knows how to regulate it's pH and the stomach acids will do their job to break everything down. So just because you drink alkaline water, it doesn't mean your whole body will turn alkaline.

The more you exercise, the more acid you may have. The more acidic foods you eat, the more acid you may have. Consuming a large amount of antioxidants will not change the pH level of your blood, but it will help your body to have less stress in maintaining its pH systems. When you exercise a lot, your blood will be slightly acidic due to a build up of lactic acid and other internal waste products. Drinking Kangen water can help with recovery after workouts.

Study on alkaline fluids

This study finds that drinking alkaline water with a pH of 9 before intense exercise was proven to inhibit the increase of lactic acid level of blood, thus increasing the lactic acid level slower. This also helped to balance the blood pH level, so that the pH of blood remains at a

normal level, when compared to the group who were not given alkaline liquids before intense exercise.

The Gut

Known as one of the top 10 surgeons in the world, Dr. Hiromi Shinya needs no introduction to the medical community. He pioneered modern colonoscopic techniques, and invented the electrosurgical polypectomy snare now common on colonoscopes, allowing for removal of colon polyps without invasive surgery. Dr. Shinya has his patients drink alkaline kangen water as part of their treatment. This is the before and after of drinking kangen water.

What is Electrolysis?

The K8 works through the process of electrolysis which is similar to the water being struck by lightning. Electricity is used to split molecules that normally are stable and wouldn’t split on their own without the electricity being applied. The water (H2O) is split into Hydrogen gas (H2), Hydrogen ions (H+), and Hydroxyl ions (OH-). The cathode breaks water up into hydrogen and hydroxyl. The hydroxyl (OH-) goes to the anode, where it is dispensed with the acidic water. This is because it is negatively charged. The hydrogen and positively charged minerals are dispensed with the Kangen water. The water is called “reduced” because the water at the cathode has been reduced to hydrogen gas and hydroxides. This alkaline water has reductive characteristics due to the presence of dissolved hydrogen gas.

In order to go through electrolysis, water must contain certain minerals, or electrolytes. Pure water with absolutely nothing (no minerals) in it is a very poor conductor of electricity and therefore it is not possible to ionize water significantly enough to change the pH or hydrogen content. These minerals, referred to as electrolytes, include: sodium, calcium, potassium, chloride, sulfate, phosphate, magnesium.
