Simply put, Free Radicals are unstable molecules that are missing an electron. They are highly reactive, and readily “attack” & “steal” electrons from other molecules. This process of Free Radicals attacking other molecules in our cells is called oxidation. If you’ve ever seen a piece of brown fruit that’s gone bad, it became that way through oxidation.
Free Radicals are formed within the mitochondria (energy center) of all human cells as a by-product of metabolism. Free Radicals are always being produced in our cells due to natural lifestyle and environmental factors; even breathing oxygen contributes to their formation. In fact, up to 5% of the oxygen we breathe is converted into harmful Free Radicals.
Hydroxyl (OH) radicals are the most potent oxidants causing most of the oxidative related deceases. Hydrogen Selectively neutralizes only these Hydroxyl Radical, converting them into water, which the body can utilize or eliminate. So there is no worry of overdose of Hydrogen as the end product is pure water. ( This is same the Hydrogen Fuel Cell that is being used for running electric cars, the output is pure natural water)
