Reltech is a medical device manufacturer that researches and commercializes reduction electron technology designed to harness the antioxidant power of electrons.

Oxidation is not only the primary cause of aging but is also considered one of the causes of various diseases. Since the human body is constantly exposed to oxidative stress, reducing it is the key to a long and healthy life.

Oxidation is the process of losing electrons, while reduction (antioxidation) is the process of gaining electrons. Reltech has been researching a series of technologies designed to efficiently, effectively, and safely supply electrons to the human body for the purpose of antioxidation, and has been developing and manufacturing products that incorporate these technologies for many years.

Reltech internally refers to its comprehensive technology for efficiently and safely supplying electrons to the human body through the skin (transdermally) for antioxidant purposes as “Reduced Electron Technology,” and refers to its own medical devices and electron supply units—which incorporate Reduced Electron Technology to provide transdermal electron supply to the human body—as “Reduced Electron Therapy Devices.”Furthermore, treatment and the maintenance and promotion of health using Reduced Electron Therapy Devices are referred to as “ Reduced Electron Therapy®.”
This website uses these internal designations and terms in its content.

Reltech products that incorporate electron reduction technology include medical devices, power supplies, and negative ion generators that utilize the structures and mechanisms of these products. Reltech manufactures all of its products at its own factory in Japan in compliance with the Ministry of Health, Labor and Welfare’s QMS Ordinance for Medical Devices, and has also obtained ISO 13485 certification.
