• How much can I drink?

    Recommended 2 Litres a day.

  • Can I use my filtered alkaline water?

    Yes. But if possible, we recommend using the pH 7 water option.

  • Is there any expiry date for the HRW?

    Please refer to the next two questions.

  • How long will the hydrogen in the water last?

    Recommend to drink within 2 hours. It is still drinkable after but may not have
    high therapeutic concentration.

  • How long can I store the hydrogen water?

    Once generated in the normal plastic or glass bottle, up to two hours to remain
    in therapeutic range. In a full aluminium bottle, up to 60 hours.

  • What should I store it with if I want it longer than 2 hours?

    Aluminiums are the best sort of bottle to store hydrogen, glasses are second

  • Can I Store HRW in fridge?

    Yes! By putting your HRW in the fridge, you will be able to keep the hydrogen
    in for a longer period of time (we’ve tested it, the hydrogen loss is significant
    lesser as compared to the one left outside the fridge – loss of 0.05ppm for the
    fridge as compared to 0.24ppm for the one left outside). Not only that, it will
    encourage you to drink more of it especially in warm climate.

  • Is it okay for babies to drink hydrogen-dissolved water?

    Yes, it is safe.

  • Can I attach the portable into soft drinks, juices and vitamin drinks?

    No, it is meant for filtered/drinkable water only.

  • Can I share the portable with another person?

    Yes, but that is a personal choice.

  • Can I use hot or cold water? (Variation of temperature Q)

    Cold and room temperature is okay to use. Warm water and hot water above
    50oC is not recommended. Heat provides hydrogen with more kinetic energy to
    Escape into its surroundings.

  • Can I put the HRW into Milo, tea, coffee, other hot drinks?(variation of Q with temperature)

    Yes, but please note that hydrogen easily escapes into the air at high

  • Can I use the water for cooking?

    Not encouraged, the hydrogen escapes fast at high temperatures.

  • Can I use the water to make cordials like ribena or orange or put lemon juice?

    Yes! You can use it in drinks as long as it is cold or room temperature. Don’t
    stir too much though!

  • Can I use it to make ice cubes?

    Yes. You can use the ice cubes on your mouth ulcers as well!

  • Can I use it to blend with juices? (variation of Q with agitation)

    Not encouraged. Excessive agitation or motion will cause hydrogen to escape

  • Can I use 1.5L water bottles on the portable?

    Yes, but it is discouraged because of its weight and water generated needs to
    be finished in two hours.

  • When is it not safe to consume HRW?

    When a patient has limited fluid restriction, follow the doctor’s, nutritionist or
    the healthcare professional’s advice.

  • Is it possible to drink too much HRW?

    Only when you have illness that requires fluid restriction, in that case, the
    amount should be adjusted to your needs.


  • How long do I need to charge the IDROGEN portable?

    One to 1.5 hours

  • When does the battery run low?

    It will indicate when the white light turns to blinking red light.
    Note: When it blinks in the middle of infusion, fear not that cycle will still
    complete. When it blinks in the beginning, you may not have a complete cycle.

  • One charge produces can use how many times?

    About 10 complete cycles, may drop to 7-8 cycles after long use.

  • How can I tell if it’s charging?

    If it is charging, the light on the charger will be red.
    If charging is complete, the light on the charger will be green.

  • Does IDROGEN produce scaling?

    No, the pH of the water isn’t changed and calcium deposits will not form.

  • How long is one generation/cycle?

    Portable takes about 5 minutes. The dispenser is instantaneous.

  • How can I know the ppm is high?

    There are two methods of testing the reagent and the meter. You can buy
    them or come to our HQ, we can do the testing for you!

  • What is the product guarantee?

    Portable: 2 years warranty of hydrogen concentration of at least 1.0ppm
    Dispenser: 5 years warranty of hydrogen concentration of at least 1.2ppm

  • Do I need to use the silicon rubber to close it? (Maintenance Q)

    Recommend to protect the portable unit.

  • Isn’t the current price of HRW expensive?

    With just RM2.70 – RM3.30per day, IDROGEN allows you to provide unlimited,
    warrantied hydrogen- rich water (HRW) to you and your family, daily, for 2-5

  • Where can I register my device?

    You may register your device here

  • Where can I find the manual?
  • Which material does the PEM cell plate use?

    The IDROGEN Portable and Desktop uses a PEM cell containing: gold, iridium, and platinum.
    All noble metals that do not corrode easily.

Hydrogen and miscellaneous

  • Heard of hydrogenated fats/saturated fats? Will drinking this hydrogenate the healthy oil I eat and turn it into saturated fats?

    No, it needs a catalyst and be in the right temperature and condition for it to be hydrogenated.

  • Are there any side effects from drinking HRW?

    No, studies so far demonstrated its safety likely owing to its hormetic effect.

  • What about alkaline water?

    Benefits of alkaline water after further studies have been found to attribute to
    hydrogen molecule, not the high pH

  • Is it okay for pets like dogs or cats to drink hydrogen rich water?


  • How about taking a bath with HRW?

    There are benefits in doing so, but it might not be practical. Using a spray and fill it with water may be a more practical idea.

  • Is there any possibility that the HRW will explode?

    No. when the gas is dissolved in water it is not explosive at all, just like if you
    mixed gunpowder in water it wouldn’t be explosive either.  Even when it is in
    the air, it is only flammable above a 4.6% concentration by volume, which is
    not a concern when talking about HRW.

  • Has hydrogen-dissolved water been proven its effectiveness by Ministry of food and drug safety in Korea, Department of health and human services in Japan, or FDA in US?
  • I thought that if water is “hydrogen rich”, then it must be acidic?

    Great question! If the water is rich in positive hydrogen ions (H+). then yes it IS acidic. But in this case, we’re talking about neutral hydrogen gas (H2), which is two hydrogen atoms tied together.
    It can be confusing to hear “hydrogen water” because we usually think of hydrogen (meaning the hydrogen ion, H+) as acidic, and that is basically the definition of pH.  The p stands for potential or power, meaning a mathematical exponent (in this case a logarithmic function), and the H stands for the hydrogen ion, which is just a proton and no electron. So pH literally means the logarithmic concentration of the hydrogen ion.
    But when we say “hydrogen water” we are referring to dihydrogen or molecular hydrogen, which is a neutral gas that is dissolved in the water.

  • I read that if you add hydrogen to water, then it makes hydrogen peroxide?

    Water has the chemical formula H2O,  and hydrogen peroxide has the chemical formula H2O2, which by comparison contains an extra oxygen, not hydrogen. So it does not, indeed it cannot, form hydrogen peroxide. The fact is, hydrogen gas does not bond to or react with the water molecules, it just dissolves into the water. It does not create some novel molecule like H4O, which would in fact be chemically impossible to form. Therefore,  hydrogen water and hydrogen peroxide are completely different substances.

  • Since hydrogen gas doesn’t dissolve very well in water, how can there even be enough for it to be beneficial?

    It is true that hydrogen is not very water soluble as it is a neutral, non-polar molecule with a solubility of 1.6 mg/L, which is relatively low. But when we consider that molecular hydrogen is the lightest molecule in the universe, we really need to compare the number of molecules as opposed to the number of grams. For example, if a single molecule weighed 2 mg (which is impossible, but used as an example), then having just one of those molecules in a liter of water would give you 2 mg/L, but there would only be one molecule.  For reference, vitamin C (176.2 g/mole) weighs 88 times more than hydrogen gas (2 g/mole). Therefore, hydrogen water at a concentration of 1.6 mg/L would have more “antioxidant” molecules than 100 mg of vitamin C, as there are more total molecules in 1.6 mg of hydrogen compared 100 mg of vitamin C. That is, 0.8 mmoles of H2 vs. about 0.6 mmoles of vitamin C.
    But more importantly, hundreds of scientific studies clearly show that these concentrations of hydrogen are effective.

  • Won’t any dissolved hydrogen gas immediately escape out of the water?

    Yes, it does immediately start coming out of the water, but it doesn’t just vanish immediately. Depending on the surface area, agitation, etc., the hydrogen gas can stay in the water for a few hours or longer before it drops below a therapeutic level. This is much like carbonated water or soda that contains carbon dioxide gas (CO2), but because it does leave, it is best to drink the water promptly before it goes “flat”.

  • Does more hydrogen equal more benefits?

    Maybe, maybe not…. there is obviously a minimum required amount needed to offer any health benefits, which may vary from person to person. Importantly, it appears that you cannot get too much hydrogen, as it doesn’t build up in your system.—you just exhale it out.  In many cases there is a clear dose-dependent effect, meaning the more hydrogen the better or greater the effect. There are also many anecdotal reports that suggest that consuming more hydrogen may offer even more benefits. But more research needs to be done in this area.

  • Is hydrogen safe?

    Yes. Hydrogen gas has been shown to be very safe at concentrations hundreds of times higher than what is being used for therapy.  Here are a few examples:
    Hydrogen’s safety was first shown in the late 1800s, where hydrogen gas was used to locate gunshot wounds in the intestines. The reports showed that there were never any toxic effects or irritation to even the most sensitive tissues.
    Another good example of its safety is that hydrogen gas has been used in deep sea diving since 1943 (at very high concentrations) to prevent decompression sickness. Studies have shown no toxic effects from hydrogen when at very high levels and pressures of 98.87% H2 and 1.26% O2 at 19.1 atm.
    Furthermore, hydrogen gas is natural to the body because after a fiber-rich meal, our gut bacteria can produce liters of hydrogen on a daily basis (which is yet another benefit from eating fruits and vegetables).
    In short, hydrogen gas is very natural to our bodies, not like  a foreign or alien substance that can only be synthesized in a chemistry lab.

  • When was hydrogen’s therapeutic benefits first discovered?

    The earliest account of hydrogen gas having medicinal properties was in 1798, for things like inflammation. But, it didn’t become a popular topic among scientists until 2007, when an article about the benefits of hydrogen was published in the prestigious journal of Nature Medicine by Dr. Ohta’s group.

  • I heard that drinking alkaline water can neutralize excess acid.

    Alkaline water is not a buffer and has low alkalinity. As such, it cannot neutralize very much acid. Many people have seen that just a small amount of soda can easily lower the pH of a gallon of alkaline water. To help put this into perspective, consider that 1 tsp of baking soda (sodium bicarbonate) can neutralize the same amount of acid as 10,000 liters of alkaline water at a pH of 10.  This is a primary reason why medical professionals have been skeptical about “alkaline ionized water”. It simply wasn’t known that the benefit of this water is attributed to the dissolved hydrogen gas until around 2007.

  • I heard that “every sick person as an acidic blood pH”. Is this true?

    Healthy blood pH varies between 7.35 to 7.45. Blood pH is tightly regulated. In physiology, if someone has a blood pH of 7.1 they are said to have acidosis even though 7.1 is actually alkaline according to the pH scale.  Very rarely do people ever get truly acidic blood (pH<7.0). If the blood pH drops below 7, the body will not survive very long. Therefore, virtually every sick person actually has an alkaline blood pH even though some may have acidosis.  Similarly, some diseases can actually cause alkalosis (elevated blood pH).  It is the disease that causes the changes in blood pH, as opposed to the changes in blood pH  causing the disease. Of course, a low blood pH can cause serious damage to the body and needs to be quickly corrected.

  • I heard that Dr. Otto Warburg won the Nobel Prize for proving that “the the root cause of all cancer is too much acidity in the body and low oxygen levels”. Is this true?

    No, it is not. Dr. Otto Warburg did do some cancer research and did make the simple observation that once a cell becomes cancerous, it relies upon glycolysis for its energy resulting in a higher production of acid. But, he did NOT receive the Nobel Prize for proving that cancer can’t survive without adequate oxygen or in an alkaline pH. In fact, his work shows that cancer thrives just as well in an oxygenated environment that is alkaline as it does under hypoxic/anaerobic conditions. In 1931, Otto Warburg received the nobel prize for his “discovery of the nature and mode of action of the respiratory enzyme” now known as cytochrome oxidase, which transfers electrons to oxygen during aerobic metabolism. In 1944, he was nominated for a second Nobel prize for his discovery and work on flavoproteins used for dehydrogenation reactions with their coenzymes.

  • How does the blood maintain an alkaline pH?

    The three main systems the body uses to maintain normal blood pH levels are:
    -Buffering components (e.g. proteins, phosphates, etc.)
    -Respiratory system (removal of CO2)
    -Renal system (excretion or reabsorption of bicarbonate HCO3)
    When acid is introduced into or produced by the body, it is quickly neutralized by the blood’s buffering components. The most important buffer is the bicarbonate/carbonic acid mechanism. Carbon dioxide (CO2) dissolves in the blood to form carbonic acid (H2CO3), which then forms bicarbonate (HCO3, alkaline buffer) and the hydrogen ion (H+). This is according to the equation
    CO2 + H2O ⇋ H2CO3 ⇋ HCO3 + H+.

  • What are free radicals?

    An uncharged molecule (typically highly reactive and short-lived) having an unpaired valence electron.

  • What are ROS?

    “Reactive Oxygen Species” (ROS) is an oxygen containing molecule that has one or more unpaired electrons, making it highly reactive with other molecules.
    Free radicals can chemically interact with cell components such as DNA, protein or lipid and steal their electrons in order to become stabilized. This, in turn, destabilizes the cell component molecules which then seek and steal an electron from another molecule, therefore triggering a large chain of free radical reactions.Excessive reactive oxygen species(ROS) causes oxidative stress which needs antioxidants to intervene in order to defend the body before it progresses into other diseases.

  • Heard of hydrogenated fats/saturated fats? Will drinking this hydrogenate the healthy oil I eat and turn it into saturated fats?

    No, it needs a catalyst and be in the right temperature and condition for it to be hydrogenated.

  • What About hydrogen, ATP, and energy metabolism?

    There is need to understand the body’s metabolism process to see how hydrogen raises body temperature.Cars run by rapidly combusting petrol, a compound of carbon and hydrogen. Humans maintain life with energy obtained through the slow combustion of food compounds (i.e. carbon, hydrogen, and oxygen) in the engines of cells called mitochondria. The nutrients in food, such as sugar, fat, and protein, are absorbed and then turned into blood sugar (glucose) before being delivered to individual cells. A high-energy substance called ATP is produced in reaction to oxygen in the mitochondria. As hydrogen is used in the process after being separated, it can be said that hydrogen plays a central role in energy metabolism.

  • Will Deuterium be produced in PEM electrolysis in the process of producing hydrogen gas?

    Deuterium is always present in water, so you do not “produce” it during electrolysis. The ratio of hydrogen to deuterium in water is approximately 6400 to 1. Using electrolysis, it is theoretically possible to “enrich” its concentration. But, to make a significant change in the deuterium levels would require performing electrolysis on the SAME water in continuous loops, thousands of times. Performing electrolysis on the water a single time (as PEM machines do) will not make a significant change in the deuterium concentration.
