How To Test Dissolved Hydrogen Level in Water


The new Trend In Japan “Hydrogen Water,” which has been popular in Japan since 2014; also known as “H2 Water,” “Hydrogen Rich Water,” “Negative Hydrogen Ion Water,” or “reduced water,” etc. the main water is rich in hydrogen molecules, which can resist oxidation and achieve beauty and health effects. It is also famous from Japan to Taiwan. Not only have manufacturers launched related products, but there are also products on the market that can be separated into hydrogen water by home appliances. Machine. But how does hydrogen water work? Is the hydrogen concentration marked on the product the actual concentration when drinking?

The machines that electrolyze water to generate hydrogen on the market used to be called “alkaline ionized water.” However, “hydrogen water” and “alkaline ionized water” come from the same machine, and they are also the same water, but the marketing appeal is different. This type of machine has been recognized by the Ministry of Health, Labor and Welfare, the competent authority of Japan, as a medical machine that can improve gastrointestinal symptoms. However, the hydrogen water produced by this machine has a hydrogen concentration of only 0.1-1ppm, which is lower than other hydrogen water products.

Japan’s Mainichi Shimbun reported on August 2, 2016, that the hydrogen water on the Japanese market is labeled as “hydrogen concentration 1.8-2.7ppm”, “0.3-0.8ppm”, and also labeled as “up to 7.0ppm”. However, looking closer at the label, you will find words such as “when generated” or “when filled” near the concentration number. It indicates the hydrogen concentration injected when the product is made, not the actual hydrogen concentration when purchased and drunk at the store.

Shinichi Hirano, a visiting researcher at Japan’s National Adult Medical Research Center (National Adult Medical Research Center), led a research team to investigate the hydrogen concentration in hydrogen water products on the Japanese market. 0.2ppm, about 0.8-1.2ppm in aluminum foil bags, and about 0.1-0.5ppm in alkaline ionized water produced by electrolysis.

The study pointed out that under normal pressure conditions, the upper limit of hydrogen concentration is 1.6 ppm. Still, the injected hydrogen molecule concentration can be increased by increasing the pressure during processing, so many products are marked above 1.6 ppm. But, when the public buys, the hydrogen concentration in the product may already be lower than the labeled concentration. In addition to the gradual loss of hydrogen from the gaps in the packaging container after the product leaves the factory because it is already in a standard pressure environment, which is lower than the pressure during processing, it will also affect the hydrogen concentration.

At present, neither Japan nor Taiwan’s regulations have a clear definition of hydrogen water. As long as it contains a little hydrogen molecule, it can be called hydrogen or hydrogen water. Hirano Shinichi believes that it should be clearly defined that the hydrogen concentration of such products must be above a few ppm to be called hydrogen water, and consumers will not be misled.

In addition, research on hydrogen water has only emerged in the past ten years. Relevant clinical trials are limited, and the effect on the human body is still unclear. Even in Japan, where hydrogen water originated, there are no products certified by the government as having health benefits. Consumers should not mindlessly follow fashion when purchasing related products.

Eight facts about hydrogen water (hydrogen water)
1. There is no clear definition in the regulations
2. The object of relevant research is hydrogen, not hydrogen water
3. No matter what kind of container packaging is used, hydrogen will gradually lose from the water
4. Utilization The hydrogen water produced by electrolysis has a lower hydrogen concentration than ordinary hydrogen water.
5. The upper limit of hydrogen concentration is 1.6 ppm under normal pressure. Still, the upper limit will increase as the pressure increases.
6. There are about 400 researches on hydrogen. Among them, there are only about 20 clinical studies on humans.
7. Although there are clinical studies on patients, there is almost no research data to confirm the effect of drinking on ordinary healthy people.
8. At present, there are no hydrogen water products certified by the government as having health benefits

Hydrogen Emerges as An Effective Treatment For Cognitive Disorders

Hydrogen Water is an Antioxidant and Prevents Brain Damage
Molecular hydrogen (H2) can protect cells and tissues from oxidative damage by selectively reducing reactive oxygen species.
Unlike other antioxidants, H2 has the unique capability of crossing cell membranes and targeting organelles such as the mitochondria and nucleus.
Drinking hydrogen water prevented the development of Parkinson’s disease in an experiment on rats. Hydrogen water reduces oxidative stress and prevents cognitive impairment associated with dementia and Parkinson’s disease [
Hydrogen water prevented both the development and progression of neural degeneration and suppressed neuronal loss in another Parkinson’s disease mice study.
Additionally, in a study on patients with Parkinson’s disease, it was found that the intake of hydrogen water reduces neurotoxic damage, which agrees with previous studies on animals. The hydrogen water had no adverse effects at high doses (1000 mL/day) [R]. Drinking hydrogen water and intermittent hydrogen gas exposure, but not lactulose or continuous hydrogen gas exposure, prevent 6-hydorxydopamine-induced Parkinson’s disease in rats. Consumption of molecular hydrogen prevents the stress-induced impairments in hippocampus-dependent learning tasks during chronic physical restraint in mice.

Hydrogen water is rapidly emerging as a potentially significant antioxidant, demonstrating promising results in protecting cells and tissues from oxidative damage. This is achieved through its ability to selectively reduce reactive oxygen species (ROS), harmful compounds that can lead to cellular damage [ .

An important distinguishing feature of hydrogen (H2) is its ability to cross cell membranes and target organelles such as the mitochondria and nucleus. This quality allows it to act at the heart of cells, where oxidative stress can be most damaging .

Scientific studies reveal the exciting potential of hydrogen water as a preventative agent against neurodegenerative conditions like Parkinson’s disease. An experiment on rats demonstrated that drinking hydrogen water can prevent the onset of Parkinson’s disease, reducing oxidative stress, and thwarting cognitive impairment linked to dementia and Parkinson’s disease ].

Furthermore, hydrogen water was found to arrest the development and progression of neural degeneration and suppress neuronal loss in another Parkinson’s disease study on mice .

A clinical trial with patients suffering from Parkinson’s disease discovered that hydrogen water intake can reduce neurotoxic damage. This aligns with previous animal studies, indicating a positive therapeutic potential for humans. The study also found no adverse effects from high doses (1000 mL/day) of hydrogen water .

Further studies on rats showed that both drinking hydrogen water and intermittent hydrogen gas exposure could prevent the onset of 6-hydroxydopamine-induced Parkinson’s disease. Notably, these benefits were not seen with lactulose or continuous hydrogen gas exposure .

Lastly, in a study on mice, it was found that the consumption of molecular hydrogen can shield against stress-induced impairments in the hippocampus, which plays a crucial role in learning tasks. This protective effect was observed during chronic physical restraint, suggesting that hydrogen water could potentially help maintain cognitive function under conditions of physical stress .

The unfolding research on hydrogen water’s neuroprotective properties is truly encouraging, pointing towards new potential preventative strategies and treatments for neurodegenerative diseases. However, as always, more extensive human clinical trials are needed to confirm these initial findings.
