Doctors Man’s on-site hydrogen inhaler [H2JI1] has scientifically proved to be the world’s first inhaler capable of increasing blood hydrogen concentration to 2.5%, advanced medical level.
And Doctors Man has launched a service to offer this INHALER for fitness clubs.

It has been proved in joint research with Keio University School of Medicine Hydrogen Gas Treatment Development Center that hydrogen inhalation with this inhaler H2JI1 can achieve a blood hydrogen concentration equal to or higher than that of advanced medical treatment, and it has also been published in the medical journal ELMER PRESS. By introducing a hydrogen inhaler that has been proven to be effective based on EBM (Evidence-based medicine), the company aim to further expand hydrogen services by providing opportunities for hydrogen fitness club members in addition to the daily intake of hydrogen water with a normal hydrogen water generator.

Hydrogen gas inhalation by has attracted a lot of attention since the “hydrogen gas inhalation therapy” promoted by the Keio University Hydrogen Gas Treatment Development Center was registered in Advanced Medical B established by the Ministry of Health, Labor and Welfare in 2016. However, the bioconcentration and pharmacokinetics of commercially available products have not been proven.

In a joint study with the Hydrogen Gas Treatment Development Center of Keio University School of Medicine, Doctors Man proved that hydrogen inhalation using their Inhaler H2JI1 can increase the blood hydrogen concentration to 2.5%.

In response to this, the world’s first hydrogen gas pharmacokinetics of an on-site hydrogen inhaler was published in the medical journal ELMER PRESS.

Published paper concludes, “From the results of non-clinical and clinical studies, it was confirmed that the hydrogen concentration in arterial blood can be increased to a sufficient level where the therapeutic effect has been demonstrated”.

Furthermore, on November 27, 2020, a press release was issued by Keio University School of Medicine stating that “one hour of daily hydrogen inhalation balances the autonomic nerves and exerts an antihypertensive effect”. The Press release also suggested that hydrogen inhalation by Inhaler H2JI1 has a preventive effect on hypertension, arteriosclerosis, stroke, and cardiovascular disease.

In response to the Press release, Doctors Man started a hydrogen inhalation service with inhaler H2JI1 at fitness clubs, not only for medical treatment of sick people, but also for spreading hydrogen inhalation to healthy people, aiming to expand varieties of hydrogen healthcare services.
