We receive many inquiries about the appropriate amount of hydrogen gas to ingest, so we conducted an in-house test and compiled an explanation.
*Details and explanations of the test results can be found here .
In conclusion, even if you inhale Alivio's low-volume hydrogen gas, it cannot be completely absorbed by the lungs after 5 minutes, and remains there until it is exhaled. Therefore, we have concluded that expensive generators that produce 100ml or 200ml of hydrogen gas per minute, such as those available on the market, are clearly over-specified, and that a low-volume hydrogen gas generator like Alivio's is sufficient to match the functions of the human body.
