H2Cap - The World's Smallest Hydrogen Water Generator - Drink Healthiest Water on the go - NOW

h2cap in its box

"Delivered on time, works great! Weird thing... People notice it on the train or in town when they see it on my buxton or highland spring water bottle (or whatever I picked up and filled from the tap that morning) and they want to know what it is. It seems to get more attention than my 8 Month old Westy Terrier when I'm at the park" - M Forwell, Cheshire UK


Meet H2CAP...

the hand held H2cap hydrogen generator

The effects of drinking H2 water are:

Fatigue recovery

Negatively charged hydrogen ions in the water donate electrons directly to cells and enhance the production of energy current, ATP (Adenosine Triphosphate). As the energy supply in the body increases, the effects of fatigue diminish and vitality increases.


By eliminating and reducing Free radicals involved in the inflammatory reaction, it has effect on suppressing various allergies.

Muscle-Energy supplementation

Drinking hydrogen rich water has a positive effect on athletes who perform repetitive movements by improving their resistance to muscle fatigue, increasing endurance and shortening recovery time.


By maintaining a healthy level of Vitamin C intake, hydrogen assists in suppressing melanin and cellulite, in addition protecting the skin from ultraviolet rays and collagen breakdown.


Hydrogen water reduces oxidative stress in the liver and contrib­utes to the reduction of serum glucose, insulin and triglycer­ides. It is similar in effect to a good diet, whereby it acts to inhibit the effect of hyperlipidaemia.


It acts to increase the number of NK cells which seek out and kill cancer cells, inhibiting the proliferation of cancer cells in our body. Some drugs companies have observed increased cancer cell death rate when giving H2 water with their chemotherapy drugs. (see study)

And so much more....

Molecular Hydrogen is the most powerful "Antioxidant"

Hydrogen rich water has an abundance of "active hydrogen" (H2), which is the lightest and most unstable element in the universe. The abundance of active hydrogen (more than 1000 PPB) works as a powerful ANTI-OXIDANT in our bodies by donating excess free electrons to unstable FREE RADICALS (especially OH- hydroxyl radicals) rendering them stable and unable to damage DNA. When this occurs and the OH- radical receives an extra electron from active hydrogen (H2), resulting in pure water being discharged from our bodies.

Active hydrogen is strong enough to restore and cure OXIDISED cells and DNA to its original state
