Safety Test

In a world large number of Universities experiments on hydrogen including our company FDR・Friendear Inc. for a while.
More than 300 thesis on improvement of ⅡModel diabetes, cerebral infarction, myocardial infarction, arteriosclerosis, dementia by hydrogen was announced in International Science Journal and others.
We are expecting that more university in a world will study about hydrogen in a future.


Safety Test of DHW Hydrogen Water:

Safety examination of Doctor Hydrogen Water (DHW) Stick’s hydrogen-rich water according to the standard examination of pharmaceutical product was performed by oral administration, carried out maximum dose.
The toxicity of the short-term, long-term dosage nor hereditary, carcinogenic preliminary examination was not recognized and it was revealed that DHW was extremely safe.
The side effect of DHW hydrogen drinking water was not recognized by clinical trial in the people at all.

General toxicity test and genotoxicity test assessment of hydrogen water; acute and subacute toxicity test of mice by 90 days oral administration and genotoxicity assay by the Ames test.
There were no abnormal symptoms nor abnormal organs were found in all study groups during the observation period.
Results of the back mutation test using bacteria also showed negative in a relatively higher dose; all the mutagen test (Ames test) results were judged to be negative.

An Open Label Pilot Study on Antioxidant:

Effectiveness of Hydrogen Rich Water on Antioxidant Status of subjects with Potential Metabolic Syndrome.
Drinking DHW hydrogen-rich water represents a potentially novel therapeutic and preventive strategy for metabolic syndrome.
The portable magnesium stick(DHW stick) was a safe, easy and effective method of delivering hydrogen-rich water for daily consumption by participants in the study.
