Hydrogen water contains hydrogen molecules that can act as powerful antioxidants. These molecules may help neutralize oxygen free radicals that contribute to disease development, inflammation, and aging. Read more to learn about some exciting research and the potentially miraculous benefits of hydrogen water.

When I first heard about hydrogen water, scam bells started to go off in my brain.  But then I started to read and realized that hydrogen water has serious potential.

What Is Hydrogen Water?

Hydrogen (H2) is the most abundant molecule in the Universe. It’s an odorless, colorless, and tasteless gas. But only in 2007 did a team in Japan discover that inhaled hydrogen gas could act as an antioxidant and protect the brain from free radicals. This sparked the interest in its potential health benefits worldwide and led to some breakthrough research [R, R].

Hydrogen water is loaded with hydrogen molecules. It was formulated as the most practical and easy way to get hydrogen into the whole body. But it’s not the only way — hydrogen can also be inhaled, injected, or absorbed through a bath [R].

Since the Japanese discovery, the effects of hydrogen have been researched in 63 diseases [R]!

It’s less known that hydrogen was therapeutically used for the first time in humans in the early 90s. It was given to 3 divers to successfully help them overcome the effects of high pressure on the brain in deep-sea diving [R, R].

Hydrogen is the smallest existent gas molecule. Because of this unique property, molecular hydrogen could penetrate into virtually every organ and cell in the body (including the brain) where it may have antioxidant, anti-inflammatory, weight-loss, and anti-allergy activity. Molecular hydrogen seems like the perfect therapeutic the world has been eagerly searching for — with very few known side effects and such wide-ranging action [R, R].

Many studies, however, are still in the early stages. It will take more clinical research to uncover all the effects of molecular hydrogen in humans.

Hydrogen Water Snapshot


  • Neuroprotective
  • Excellent antioxidant
  • Anti-inflammatory
  • Protects organs
  • Lowers cholesterol and blood sugar
  • Improves a wide variety of diseases
  • Is not toxic even at high concentrations


  • Although it has no known side effects, more research is needed to understand the  long-term effects

Health Benefits of Hydrogen Water

1) Hydrogen Water is an Antioxidant and Protects the Brain

It was first shown that molecular hydrogen (H2) could protect from damage by reducing the most toxic reactive oxygen species (ROS) in cells. Inhaled hydrogen also easily reached the brain to reduce injury in rats with stroke [R].

In the first pilot study of 38 stroke patients, a hydrogen solution (IV) was safe and had a mild antioxidant effect [R].

In a small study (DB-RCT) of 17 patients with Parkinson’s disease, those who drank hydrogen water had improved symptoms. Those who drank regular “placebo” water, however, experienced a worsening. There were also no adverse effects to drinking 1L of hydrogen water daily for almost one year [R].

No study so far has looked at the effect of hydrogen water alone on Parkinson’s Disease, though. In the completed studies, patients drank hydrogen water as an add-on to regular medications (L-Dopa) [R+].

In rats, hydrogen water reduced oxidative stress and prevented Parkinson’s Disease. Curiously, hydrogen seems to achieve better results with lower doses. Rats who drank hydrogen water did better than those who constantly received higher amounts of hydrogen intravenously [R].

Hydrogen water prevented cognitive, learning, and memory problems in mice under stress by acting as an antioxidant. It also protected cells in the brain’s memory hub — the hippocampus — from the detrimental effects of stress [R].

Hydrogen water could potentially be used to prevent cognitive and stress-induced disorders with more research.

2) Hydrogen Water May Improve Mood Disorders

Hydrogen water restored the natural growth of brain cells in mice. Since this also happens in people who overcome depression (with antidepressants or otherwise), hydrogen water has the potential for improving depression and other mood disorders [R, R].

3) Hydrogen Water Suppresses Inflammation

In one pilot study, 20 patients with rheumatoid arthritis drank 0.5 L/day of hydrogen water for 4 weeks. By the end of the study, all patients with early rheumatoid arthritis achieved remission and 20% became symptom-free [R, R].

Molecular hydrogen (H2) also had anti-inflammatory effects in many animal studies [R, R].

4) Hydrogen Water Reduces Muscle Fatigue and Weakness

In an experiment with 10 young athletes (DB-CT), drinking hydrogen water reduced lactic acid build-up during heavy exercise and decreased muscle fatigue [R].

Drinking 2 L of hydrogen water daily helped 8 cyclists power through sprints with more energy and less exhaustion in one small 2-week study [R].

In a study on mice with a serious muscle-wasting disease (Duchenne muscular dystrophy), hydrogen water prevented abnormal body mass gain and increased the production of the antioxidant glutathione peroxidase. Hydrogen water could potentially improve muscular dystrophy in DMD patients [R].

5) Hydrogen Water May Prevent Metabolic Syndrome

Hydrogen water reduced fatty liver in mice with type 2 diabetes, obesity, and those fed a high-fat diet. It also boosted energy use and reduced levels of glucose, insulin, and triglycerides [R].

In rats, hydrogen water could prevent hardening of the arteries, atherosclerosis [R].

In a pilot study on patients prone to metabolic syndrome, drinking hydrogen water (1.5 – 2 L/day) for 8 weeks increased in HDL-cholesterol and decreased total cholesterol [R].

6) Hydrogen Water May Boost Weight Loss

Long-term drinking of hydrogen water helped lose body fat and weight in rats. It boosted burning fats and sugars for energy, without any change in diet. In fact, drinking hydrogen water had similar effects in the body as calorie restriction [R].

7) Hydrogen Water Enhances Energy Metabolism

Drinking hydrogen water protected the body’s energy powerhouse, the mitochondria, in several studies of 41 people with muscle diseases. They drank 0.5-1 L of hydrogen water per day [R].

Drinking hydrogen water also stimulated energy metabolism in mice  [R].

8) Hydrogen Water Helps Diabetes

Drinking hydrogen water decreased cholesterol, improved glucose tolerance and insulin resistance in a study (DB-RCT) of 36 patients with type 2 diabetes or prediabetes (impaired glucose tolerance). The patients drank 900 mL of hydrogen water daily for 8 weeks. This may be a safe and simple way to reduce the risk of type 2 diabetes in those at risk [R].

9) Hydrogen Water May Alkalize the Body

Metabolic acidosis is when the blood drops and becomes more acidic, which can happen from intense exercise. Drinking 2 L of hydrogen water daily increased the blood pH before and after exercise after 2 weeks with no side effects in a study of 52 healthy, active men (DB-RCT). Hydrogen water was safe and had an alkalizing effect on the blood that can neutralize the post-exercise pH dip [R].

10) Hydrogen Water May Fight Cancer

So far, only cellular studies point to the potential of hydrogen water for fighting cancer.

Hydrogen water combined with increased temperature (hyperthermia) had a strong cancer-killing effect in cells [R].

In human cancer cells, hydrogen water suppressed tumor growth by reducing oxidative stress [R].

Hydrogen water also blocked the creation of new blood vessels in human lung cancer cells, preventing cancer from spreading and growing [R].

11) Hydrogen Water May Reduce Side Effects of Chemotherapy and Radiation

In one study (RCT) of 49 patients on radiation therapy for liver cancer, drinking hydrogen water (1.5 – 2 L/day) improved the patients’ quality of life and appetite. Hydrogen water could reduce oxidative stress and damage from radiation without compromising its cancer-killing effects [R].

In mice, drinking hydrogen water increased survival, reduced kidney damage and weight loss from a chemotherapy drug (cisplatin) [R].

12) Hydrogen Water Boosts Skin Health

Hydrogen water given through an IV solution safely improved skin health in 4 patients with skin redness and inflammation, and pain. The skin redness went away after a couple of days of treatment and did not come back [R].

Bathing in hydrogen water for 3 months noticeably reduced skin wrinkles in 6 people. Hydrogen water could also boost collagen production, reduce UV damage and act as an antioxidant in skin cells. Warm hydrogen-infused baths could be a pleasant, safe way to reverse skin aging [R].

13) Hydrogen Water Enhances Wound Healing

Hydrogen water intake via tube feeding in elderly patients reduced the wound size of pressure ulcers and enhanced recovery [R].

14)  Hydrogen Water May Improve Bladder Health

In rats with a blockage in the bladder, drinking hydrogen water reduced bladder volume by neutralizing oxidative stress. It also improved the responsiveness of bladder muscles. As a strong antioxidant, hydrogen water could potentially help those with a bladder obstruction [R].

15) Hydrogen Water May Protect The Heart

In diabetic mice, hydrogen water significantly improved heart health and prevented heart disease. It could become a nutritional intervention for preventing heart problems in people with diabetes [R].

16) Hydrogen Water May Protect the Eyes

Hydrogen-loaded eye drops aided the recovery of eye injuries caused by high eye pressure in rats. It protected the nerves in the eye by its antioxidant action [R].

A hydrogen solution reduced detrimental blood vessel growth in mice with eye injuries from chemicals. Hydrogen solutions could be used as a first-aid eye rinse to prevent blindness from chemical burns [R].

17) Hydrogen Water May Prevent Hearing Loss

Hearing loss often results from oxidative damage (due to aging, noise, or drugs). Molecular hydrogen protected the cells responsible for hearing from this damage and increased their survival [R].

In guinea pigs, hydrogen water prevented the death of cells responsible for hearing after noise exposure. Hydrogen water could potentially protect against hearing loss caused by noise or other types of oxidative stress [R, R, R].

18) Hydrogen Water May Combat Allergies

Drinking hydrogen water stopped immediate-type allergic reactions in mice. These occur within a couple of minutes and are more characteristic of Th2 dominance. Hydrogen stopped the allergies not only by its antioxidant action but also by blocking the whole allergic pathway [R].

Hydrogen water is a promising potential remedy for people with allergic, inflammatory conditions like eczema as it seems to balance the immune response. In mice with eczema, hydrogen water improved symptoms by suppressing inflammation and balancing both Th1 and Th2 responses [R].

19) Hydrogen Water May Protect the Kidneys

Hydrogen-rich water protected the kidneys from damage in rats. It could reduce oxidative stress, improve kidney blood flow and function (lowering creatinine and BUN) [R+].

Hydrogen added to the dialysis solution reduced inflammation and high blood pressure in 21 patients on dialysis because of kidney failure [R].

20) Hydrogen Water May Protect the Liver

In 60 patients with Hepatitis B (RCT), drinking hydrogen water as an add-on to regular treatment was safe and reduced oxidative stress  [R].

Drinking hydrogen water suppressed liver scarring in mice by protecting liver cells from free-radical damage [R].

Hydrogen water also significantly improved liver function and reduced oxidative stress in patients with chronic hepatitis B [R].

22) Hydrogen Water Could Promote Gut Health

Hydrogen-rich water prevented damage to the stomach lining in rats by its antioxidant and anti-inflammatory effects. Hydrogen water could potentially protect healthy individuals from gut damage [R, R].

23) Hydrogen Water Could Protect the Lungs

Rats who drank hydrogen water were protected against lung tissue injury. Hydrogen water reduced inflammation and oxidative stress (by reducing NF-κB) [R].

24) Hydrogen Water May Protect From Radiation

Molecular hydrogen has the potential to be used as a safe radioprotective remedy. Giving mice hydrogen water before radiation increased their survival rates and protected the heart from damage [R].

Hydrogen also increased the survival of white blood cells exposed to radiation [R].

25) Hydrogen Water May Relieve Pain

Hydrogen water was not better than the placebo in one study (DB-RCT) of 30 patients with painful, inflamed bladder (cystitis). It did help reduce pain in 11% of the patients [R].

Drinking hydrogen water could reduce neuropathic pain in mice due to its well-known anti-inflammatory and antioxidant effects. Clinical trials would need to confirm this success, but hydrogen water holds promise for safely improving otherwise hard-to-treat neuropathic pain [R].

26) Hydrogen Water May Increase Longevity

The ability of molecular hydrogen to protect the DNA and the mitochondria from oxidative damage may have beneficial effects on chronic diseases and cancer. But perhaps it could help slow down or reverse the aging process itself. A couple of cellular studies give us some interesting clues [R, R].

It was already discovered that hydrogen can prolong the life of stem cells by reducing oxidative stress [R].

A hydrogen-rich environment reduced both oxidative stress and aging in cells. Some scientists think that drinking hydrogen water could increase longevity in humans [R].

27) Hydrogen Water May Kill Bacteria and Improve Oral Health

Drinking hydrogen water 4-5 X daily improved gum health in 13 patients with inflamed gums after 8 weeks. It also boosted blood antioxidants and enhanced the effects of other gum disease treatments [R].

Hydrogen water could kill the bacteria that most commonly cause gum disease and cavities. It could be used to improve overall oral health [R].

28) Hydrogen Preserves Transplant Organs

Hydrogen water could help preserve and reduce damage to transplant organs without any toxic effects. It reduced the inflammation and injury that usually happens when donated organs are stored, which could help save more lives [R].

Mechanism of Action and Genetics

Hydrogen has the unique capability of entering cells and even tiny structures within the cells (organelles), such as the mitochondria and nucleus (where DNA is stored). Other molecules cannot penetrate this deep into cells [R, R].

Hydrogen water affects various pathways, such as:

Where to Get Hydrogen Water

As hydrogen water is becoming more popular, you can now find:

  • Hydrogen water in a bottle (around $3 per bottle)
  • Hydrogen tablets to dissolve in water yourself
  • Small portable hydrogen water makers
  • More sophisticated hydrogen water generators and machines you can use to add hydrogen gas to water in your home

Taking lactulose is another way to naturally increase hydrogen in the body. Although humans can’t produce molecular hydrogen, our gut bacteria can. When we take in lactulose, our gut bacteria create a large amount of hydrogen. Lactulose increased hydrogen in the body similarly to hydrogen water in a study on 65 healthy people and those with Parkinson’s Disease [R].

Safety, Dosage, Side effects

Molecular hydrogen (H2) has no known side effects. It’s not toxic even at high concentrations. In fact, it seems that smaller amounts of molecular hydrogen have a stronger, more beneficial effect than very high amounts [R].

In most clinical studies, people drank 0.5-2 L of hydrogen water daily.

After drinking hydrogen water, about 40% of the H2 is absorbed by the body [R+].

  • Tara Zenker

    Which affordable hydrogen rich water generator do you recommend?

  • Lind

    Well this is worrisome if you read through the studies…

    As described above, recent studies indicate that oral consumption of hydrogen-rich water produces many beneficial effects on the body, including positive effects on the intestine, brain, liver, muscles and bones. On the other hand, a recent study [1] in mice showed that the neuroprotective effects of oral hydrogen water are mediated mainly by enhanced production of ghrelin by the stomach. Unfortunately, ghrelin is a peptide hormone that may induce many negative effects, including weight gain, fat deposition, reduced fertility and a higher risk of cancer [2,3].

    I find myself unable to leave your blog! As the detailed view about Hydrogen water. I also like to add one more advantage of drinking hydrogen-rich water. It can protect against the neurological damage of brain injury, both the type that occurs during surgery and stroke and that which occurs over time due to oxidative stress.

  • Junaidi Lim

    I live in Singapore and travel between Singapore and Jakarta for work. I get to know about Hydrogen water in Exhibition in Singapore , and I purchase the hydrogen bottle water, which can produce 330 ml hydrogen water, so its great to bring around. What I get direct benefit is : i have more energy when i am do weight lifting in the gym , and no muscle pain after my gym exercise . Moreover, I feel i can clean all my urine when i went to the toilet . This is amazing. You should try get a reputable product and take it as your daily water. Health is very important , i am 48 yo male

    Hi everyone! I have a Mobile Molecular Hydrogen Generator that turns potable water into super anti-oxidant water. It can Create up to 1,500 parts per billion (PPB) unlike kangen it can only produce 100-200 PPB and no monthly filter maintenance.

    1. Lind

      Cathlyn, what is the brand??

  • Filibert

    H2 molecules directly convert the two worst cytotoxic radicals into harmless substances. H2 therapy also up regulates or down regulates several different groups of genes, which may be why there is such a wide range of health effects. Modern life has conserved many of the genes that were required for ancient life to live in a reducing atmosphere with abundant hydrogen. Hydrogen is the smallest and most abundant chemical in the universe.

  • Michael Edwards


    I am new to this site and just bought a Japanese system. I don’t care about the science per se, after being told trans fats are fine I realized science will never catch-up to real world demand in regards to health, but the personal testimonies are great. Just wondering if someone could recommend five tangible health life-hacks that could change the quality of my life. So far I am tracking apple cider vinegar daily.
    Thanks for your time.

  • Kay Vogt

    Hydrogen water machines can be purchased at and for a limited time you can participate in a medical study to get the machine for free.

  • K B

    Hi everyone. I’ve been taking Hydrogenized water (made in Japan, this is not from a machine) for 2 years and I know actual people have many amazing results including myself. People exactly have “The Health Benefits of Hydrogen Water” that is written on this page by Joe. However we have to choose a good one. There’re some low quality products out there.

    I was told any water that using a machine at home is risky and costly, because it’s expensive and needs high maintenance of a machine. So I won’t get a machine anyway.

    Thanks, Ron

  • Anthony Magness

    Angela I respectfully and professionally have to disagree with you. Although you are correct that chemical alkaline water is not only a scam but it’s dangerous for your health and the vast majority of ionizers on the market are a complete waste of money there is one that does make a non chemical alkaline water that is rich in hydrogen. Unfortunately there is a lot of false and misleading information online.

    There are a handful natural sources around the world that produce hydrogen rich water. In the 1970’s the company Mel is referring to were the first to study those water sources and to successfully recreate it in a lab. Since then they has successfully developed medical devices that make a hydrogen rich water source with more than sufficient amounts for humans. These machines are backed by more that 1600 doctors and used in hospitals in several countries to prevent and treat chronic diseases.

    For 3 years as a hydration and water quality specialist I worked directly with the WQA with water improvement and distribution. I have seen the studies first hand of these medal grade devices and the hydrogen levels that they produce. They are the ONLY ionizers on the planet that meet the WQA’s standards and because their technology is patented it will most likely remain the only one.

    1. Cristina Mojica

      Hi Anthony. May i know the hydrogen machine and the manufacturer. Where can i buy it? Do they manufacture mobile hydrogen generator machine? Thank you. GOD Bless!

  • S. Bari Mian

    Paul, Sir did you test the water using H2-Blue? It is the PPM (mg/L) that matters, higher the concentration, better it gets! Would you please share your findings!

  • VRP

    Hi Cody, Same request here if you could let me know which study’s conclusion doesn’t match with its text. This will be helpful.. thanks!

  • Angela McNabe


    All so-called alkaline ionizers and the high pH water they produce have been declared worthless by experts in biochemistry and physiology. Why? Because alkaline water is instantly acidified in the stomach – how long did it take someone to figure that one out? Then, the ionizer devices don’t make enough H2 for a mouse experiment so forget that claim. Alkaline pH water was a nothing more than a mistake that became a fad and promoters need to get over it…

  • Paul Bond

    I have yet to try H2, I’m hoping my H2 generator will arrive in 2 days, but regarding the H2 Water, I got the impression that it was a gas delivery system as much as anything (which I imagine would be good at targeting the digestive system in particular), but with gas maybe that’s not necessary, and it would be all pervasive.

    My intention is to use it to breathe it, and also get a little bit in drinking water as well. I wouldn’t rule out using tablets either if for no other reason than convenience when travelling.

    I also get the impression that although alkalizing devices have their fans, it appears that their benefit all this time wasn’t the pH, but the Hydrogen.

    I have a couple of niggles I’m eager to test it out on (eg. a slow healing very deep surgical scar on my foot, and want to bag it and flood it with gas). Time will tell, as that is something I can measure progress myself visually.

  • Alex Tarnava

    Caitlin this is incorrect in every possible interpretation. Izumio is a decent product however the small container sizes may be insufficient dosing for some of the benefits derived from H2. Izumio is not even the highest ready to drink concentration, H2Bev is. There are machines on the market that produce hgiher concentrations such as sold by trusii, and the open cup tablets produce significantly higher concentrations of H2 using patent pending dissolution kinetics, in much larger quantities of water(so higher concentration and dosage)

  • Caitlin

    Amy, as far as I know, Izumio has the greatest amount of hydrogen atoms in comparison to other products. That is the most impressive and valuable part of Izumio that makes it stand out, makes it more effective than any other product. I’ve been using it since the beginning of January. I had the awful flu this weekend, felt so bad on Friday. I drank 3 or 4 packets (I cannot remember the exact number) and woke up feeling so much better on Saturday. If you’ve heard anything about the flu going around, that kind of recovery rate is unheard of. Now, I am a fairly healthy person, and my liver is not as damaged as others. Everyone’s body will react differently. This is just my findings that feel supportive to the taking of Izumio.

  • Mel

    Kangen water! The best and the original tha t others try and imitate.

  • Amy

    Have anyone tried Izumio hydrogen water from Japan ? It has a 2.6ppm , any comments will be appreciated.some people told me that Hydrogen machine easily get moldy and the water source is not as clean.

  • Philip Goulopoulos

    Mike, I would appreciate your input, so please make your recommendation, and also mention the runner up product you passed on.

    This is fraud plain and simple. Take a beginners chemistry class and see how many ways hydrogen is chemically available for the body (aka acid). Look at the references listed in this article and you will find that the conclusions don’t match the text. ….and they forgot to add that it regrows hair, makes you see into the past, and helps you pick better lottery numbers…sheesh.

    How I’d the cheaper version by cooks companion is it worth it I saw it on a shopping channel Evie does if work like they say it’s from China n I don’t trust too much stuff from chins

  • Ryan

    Electrolyzed Hydrogen Water works. Last May, I bought two portable hydrogen generator branded Kenho Lumbini in Singapore. Passed a unit to my brother in law who is suffering from type 2 diabetes. After 3 months consuming Hydrogen water , approx. 1.5 liters per day, the diabetes improved tremendously. As for me, being disease free, there is no changes.

  • Nikolay D

    What brand did you buy? Did you perform the test? There may knock offs on the market. $400 machine will not going to last. In a year or two you might start drinking mold and rust from the machine. Be very cautious. I bought my machine for several grands. It lasts 20-25 years. The company is 44 years on the market!! If your machine does’t have 3 types of cleaning, immediately return it to the seller!

  • Gianna

    Can anyone recommend a good hydrogen machine?? Does this help with lymphatic flow? Thanks

  • Skypp

    My first try of hydrogen water was with the tablets, specifically Aquah2 from Amazon. They’re great. I add one more than the directions say: for example 3 tablets in a 23-ounce Perrier bottle, cap tightly, wait 20-30 minutes, drink within a day and keep it tightly capped & cool. Nevertheless, I quickly bought a hydrogen machine and use the tablets when I’m busy or traveling. Some people add a small amount of lime juice when brewing, but no other additives are generally added before it’s made. I am still experimenting, but I love this water and won’t be without it again.

  • Skypp

    You cannot speak to the efficacy of something until you’ve tried it. I bought the tablets just to see. One week later, I was investing in a $400 hydrogen water machine and hope to upgrade that soon. Why? BECAUSE IT’S AWESOME STUFF. I feel better, look better and even wash my face with it. (Immediate glow, freckles diminishing, soft, healthy skin). People who decide something doesn’t work because their “science” tells them so are a special kind of ignorant. MANY very competent scientists are drinking hydrogen water and sharing how to make their own without buying a machine. They seem to think it’s good stuff. Personally, I went for the machine because it was was an easy way to make the water I’ve come to LOVE. Try things for yourselves and don’t ever listen to naysayers, especially ones who have never even tried what they are criticizing.

  • Josh

    So Hydrogen water has PH of WHAT ?

    H2 in solution with NO H+ ions????

    You are telling me Hydrogen water has PH of 7 ?

    this is not alkaline water which is PH above 7 and
    is Hydrogen ion hungery – obviously

    BTW have you guys studied CHI CULITVATION –
    and CHI GONG ? I think you are becoming so BRAIN
    heavy that you might not be grounded !

  • moon

    whether it’s Hydrogen water or regular water one should not over drink like anything else (read that some place, that you can “drown”) — there should be a balance to everything.

  • Alex Tarnava

    You are confusing molecular hydrogen with ionic hydrogen which is a function of pH, and getting that wrong as increasing h+ would lower the pH.

    This is saturating molecular hydrogen, a neutral gas, into water.

    I won’t touch on your latter (incorrect) comment as you don’t even understand the basic premise.

  • Anonymous

    I seriously doubt that hydrolyzed water has any benefit at all(except perhaps a placebo effect benefit). Here’s why:
    When we drink water regardless of its PH it has to go through our digestive track, so by the time the water is absorbed into our bodies it will have its PH changed multiple times. At the final stage its PH will be determined by all our bodies processes to it. More important then, it seems, is the purity of the water and the levels of toxic substances that may be found in it. So apparently the only way to obtain the benefit of the anti-oxidant function of hydrogen would be to inject it, but this could be potentially very dangerous or even fatal.

  • KP Lim

    We have measured the amount of H2 in Izumio and our H2 portable generated water, Izumio is slightly more than the H2 we generated. However, portable generator is much much more economical.

  • Jacqkat

    What’s your opinion on Molecular Hydrogen tablets?

  • K9mom

    What is your opinion on Izumio Hydrogenized Water, any side effects? Can I get sick from drinking too much of it? I have MS & was told it was good for that but not about any possible adverse effects. Thank you & have a Blessed day. 🙂

  • Ed C

    I read several of the studies referenced in the “hydrogen water” section of the the site. I noticed that the studies that showed significant effect often/always(?) generated their water by placing magnesium in water, did nothing to remove the magnesium hydroxide from the water, did not compare result to that obtained from drinking a magnesium hydroxide solution. I am suspicious that all significant effects are due to magnesium and/or hydroxide in the water rather than from dissolved hydrogen.

    Did anyone find any studies which eliminated this possibility?

    Note that some abstracts do not mention the source of their “hydrogen” water so you may have to find the full study text and even then there may not be any mention. In such a case, the study does not tell us whether the dissolved hydrogen has really done anything.

    We are seeking the truth, right?

    1. Alex

      There are hundreds which use different methods. Also hydrogen rich salines, hydrogen inhalation… many use magnesium, and the magnesium intake will have an additive effect, however there are many studies using neutral h2 water via bubbling gas into the water.

      studies on [Molecularhydrogenfoundation] is a good database

  • Shawn Wells

    Aqua magic HE is $99 on Amazon and has the best reviews. It does .8ppm, but can be run a second time to get twice that if needed. It’s portable which is nice. Any thoughts on that one? The two Anself ones have bad reviews. I’d like to get something that works in line with the refrigerator water dispenser too. Does that exist?

      Dear friends. Greetings to all and of course Joe Cohen!

      My recommendation after buying three (3) different types of equipment is definitely the equipment with SPE (PEM)
      Are expensive but there is nothing better worldwide (I import teams from Japan too)
      This is a summary on the subject very complete

    hello self hackers, anyone willing to recommenced a product. I’m interested in therapeutic dose H2 (5-7ppm), portable or at home machine. Thanks

    1. Alex Tarnava


      tablets, not a machine but they hit those levels

  • Alex

    Molecular hydrogen is showing to be dose dependent. All clinical studies underway and the human studies already published have achieved 4-5 PPM of H2 through a complex system. The only product on the market that can achieve this is Drink HRW’s Rejuvenation

    Hydrogen sticks and ionizers tend to get 0.1-0.5 PPM so only a fraction of the required dosage has videos demonstrating prep and testing with the methylene blue reagent

    1. Angel

      These videos show the technical measurement of ORP and ppm of hydrogen in water.

  • Diarmuid Galvin

    Have you measured the ppm H2 in the water content from the device you have linked to?

    2. Alex

      Yes. There are also videos on the site

  • Ali

    I just bought the Anself product you recommended and don’t feel any noticeable effects after 3 days. One review of this product states :

    “Creates lots of pretty H2 bubbles, however, when I tested the water using H2Blue the water stayed blue after the very first drop, proving that the product does not work as claimed.”

    Have you tested the product yourself, or can you recommend another that will definitely produce hydrogen-rich water?

    Thanks for your time and all the effort you put into this site!!

      and the Lourdes one seems to be the best stationary.

      the one recommended on this site is not good enough plus it does NOT separate the water between + and -.

    Alkaline Water (pH measurement) is missing the point, it is the ORP measurement which matters, it needs to be a negative 3 figure milli-Volts value, but never as negative as -500mv.

    I stopped using water pitcher filters, because construction is noticeable cost cut, the monthly cartridges cost mounts up, they have trivial water capacity, may use potentially harmful plastics (BPA is not the only plasticiser which can be a harmful hormone mimic), and most have poor and/or harmful filtration.

    I have a Big Berkey for the filtration part (excellent filtration/sterilisation, mostly Steel and much cheaper over the years of life of the two huge Black filter sticks, and can have post filters added for nasty stuff like Fluorine and agricultural chemicals) and an Anself Portable Hydrogen Rich Water Ionizer, the resulting water read as -200mv on a brand new, quality ORP meter.

      ORP measurement is also missing the point, since ORP is only the potential. You have to know what made the negative ORP and you also have to know the concentration of it present.

      The concentration of H2 (and thus more/easier availability of therapeutic dosages) is what matters. A low -ORP can easily be orthogonal to what we are after. Water can have a -ORP reading and still have a low concentration of H2.

      It is the PPM (mg/L) that matters. The higher concentration, the more you can take in.

      1. josh

        not to mention somewhere I read the Hydrogen needs to be “active”?
        Found a website somewhere debunking ORP. and said PPM is only guidelines but cant be a perfect element of measure.

    Picked up the model that was recommended on this past Monday, 8/29/16. Biggest difference I’ve noticed besides a subjective mild anti-inflammatory effect is that my post-meal and fasting blood glucose has stayed somewhat low. During the following readings I was consuming hydrogen water as my primary water source, first meal of day was fat-rich, unless noted otherwise, carbohydrates were concentrated in evening.

    With H2 enriched water:
    91 mg/dL 23:35 8/29 (post meal, carb rich)
    81 mg/dL 10:06 8/30 (low carb morning)
    83 mg/dL 21:36 8/30 (post meal, carb rich)
    84 mg/dL 23:13 8/30 (ate more p.c’d white sweet potatoes)
    77 mg/dL 8:19 8/31
    79 mg/dL 17:34 9/1 (unintentional concomitant intake of carbs following a high fat meal, measured ~1 hr after intake)
    83 mg/dL 10:46 9/2
    91 mg/dL 17:59 9/3 (consumed abundance of carbs , ate a few coconut hi-maize cookies two hours ago)

    Some very recent pre-H2 enriched water samplings of post-carb meal spikes, magnesium adequacy was ensured throughout:

    101 mg/dL 23:01 8/28
    179 mg/dL 19:50 8/28 (ate a rather large serving of sweet potato fries)
    101 mg/dL 23:45 8/25 (post meal, carb rich)
    137 mg/dL 23:59 8/24 (sweet potato fries)
    99 mg/dL 23:59 8/23 (before bed, meal >2 hours prior)

    Very interesting to see that my own objective measurements are corroborating with the research.
    Mood effect is present, although somewhat subtle; probably secondary to reducing pro-inflammatory cytokines.

    Since it increases endogenous anti-oxidants it’s likely that it works in part as a pro-oxidant.
    If you got your nrf2 epigentically blocked by mycotoxins you can damage yourself very serious.

    I have cfs and the hydrogen water oxidized my brain away. Gave me terrible “adrenal fatigue”.
    Got over it by resting, pqq, lllt and sleep.
    I have similar experiences with R-Lipoic Acid, garlic, green tea, gymnostemma, grape seed, etc wich are all strong nrf2 inducers.

      Use DIM to remove mold toxins from Nrf2…Bacopa also good for mold + nrf2 upregulation.

  • Van Beran

    Seems exciting Joe. Have you honed in on the best way to incorporate its daily use into a household? Which machines are best? Or if the sticks work?

    1. Joseph M. Cohen

      I don’t think stick works

  • GM

    Great article! One question: Are you happy with the product recommended here? (Anself Portable Hydrogen Rich Water Ionizer). Does it really work? Lack of reviews make me a little worried. This stuff looks amazing…

    1. Joseph M. Cohen

      I bought a different, more expensive one, but I were buying now, I’d go for the cheaper linked one. Haven’t tried that one, though.

  • Santino

    Could hydrogen water harm if someone wants to treat chronic infections such as intracellular mycobacteria? For example by attenuating inflammation are being a strong antioxidant?

    1. Joseph M. Cohen

      i don’t think so

  • Astir

    What do you think of this product?

    1. Ed C

      It doesn’t tell you what minerals are in the “mineral stones” in the filter.

      Why not buy a cost-effective filter and buy beneficial mineral salts to add to your pitcher. You’d know what was dissolved in your water and would not be overpaying for someone to put “stones” in your filter when you really don’t know that they dissolve anything of benefit in the water.
