rH2 means “relative hydrogen”, a scale that measures the true reduction capacity of simple components (antioxidants of low molecular weight) in aqueous solution.
The scale ranges from 0 to 42, where 28 is considered the neutral value.
Values between 0 and 28 represent antioxidant substances; while values between 28 and 42 are found in oxidant substances.
What does it mean?
Even though this parameter is not yet very well known, it is the largest indicator of the ability of water to reduce any acids present in the body.
It should be noted that complex reducing agents (e.g. Vitamin C, Vitamin E, Coenzyme Q10…) will not necessarily influence the ORP and thus will not enhance its anti-oxidant capacity.
In contrast to the ORP – which is an indicator of the anti-oxidant capacity of hydrogen, but highly dependent on pH, rH2 represents the true index of oxidation/reduction potential – the number of electrons available.
How to find out the value?
Unfortunately, it is a value that – unlike the pH – does not appear on bottled water labels. It can be measured by a suitable probe: a value of rH2 of less than 10 represents a higher reduction potential.
