Mechanism of hydrogen generation ceramic.


The hydrogen generation ceramic used for DOKOSUI MX is mixed with our company’s original blend of metals such as calcium, magnesium, potassium, iron, and zinc.The hydrogen generation ceramic is configured in a way so that oxidation and reduction start simultaneously when it comes in contact with water due to the potential difference. Therefore, when DOKOSUI MX is put in water, direct current (DC) electricity is generated. The water (H2O) is electrolyzed by this DC electricity to produce hydrogen bubbles.Furthermore, unlike conventional hydrogen generation materials (mainly made of magnesium metal), extremely small volumes of different types of metals used for our hydrogen generation ceramic are sintered without being oxidized. As a result, oxidation of metals caused by electrolysis is almost completely prevented. For that reason, our hydrogen generation ceramic can produce water containing a high concentration of hydrogen for approximately two to three months* without the need to replace the stick with a new one.
The amount of dissolved hydrogen in water made with DOKOSUI has been approved by the Japan Hydrogen Water Promotion Association. →

Electrolysis of water


Measuring DC electricity using a tester
You can use a tester to confirm that DC electricity of 334mv* is flowing in the water. *The voltage (mv) varies depending on a measuring point.




High concentration hydrogen.


We put DOKOSUI in a 500-milliliter PET bottle of water * (the water was refilled everyday) and measured the hydrogen concentration using the ENH-1000 Dissolved Hydrogen Meter.

*We used tap water of Suita City in Osaka for this measurement test. The hydrogen concentration varies depending on the water temperature and water hardness.


  ・1st day : 1,456ppb

  ・1st week : 1,104ppb
  ・2nd week : 966ppb
  ・3rd week : 825ppb
  ・4th week : 704ppb
  ・8th week : 567ppb

Safe and free from dissolution of foreign substances.

Environmental Management and Technical Center (EMATEC) has certified that water made using DOKOSUI conforms to the water quality standards for drinking -water in terms of arsenic,lead,cadmium,chromium,mercury, cyanide, aluminum,copper, and manganese content, as well as compounds of these substances..

Large quantities of magnesium oxide dissolution and the danger of it being absorbed into a human body have been pointed out for conventional hydrogen water sticks (products mainly made of magnesium metal) in the market.
