Although research is in its early stages, with the seminal article being published in Nature Medicine in 2007, so far over 600 studies have been published indicating improvements in over 170 different disease models across every organ in the body. While more research is needed, studies have suggested that hydrogen-rich water is an effective tool in reducing oxidative stress, amongst many other potential benefits.

There is limited evidence to suggest the best dosing protocols of molecular hydrogen, but we have found that a minimum of 1-2 tablets per day is required, with some using 5-6. Many people find greatest effect by consuming 4 tablets, or 4 bottles of water per day for the first 30 days, and then if you choose, reduce the dosage to 2 per day.

The tablets require slight stirring as the reaction finishes. Some find it easiest to swirl the cup, blow on the top as you would a hot beverage or give it a quick stir. Slight agitation allows the residue on the top to fully react.

Yes: Being a reaction between the element magnesium, and water- to create H2, or molecular hydrogen, a molecule comprised of 2 hydrogen atoms, which is the Universe’s oldest atom, not much could qualify as more natural!

 In over 1000 published articles no side effects have been observed. Hydrogen is used to prevent decompression sickness at thousands of times higher concentrations. 

Note that these tablets do contain magnesium- so exceeding the RDA of Magnesium can have associated risks (i.e diarrhea). We suggest limiting to no more than 6 tablets daily. In certain people with diabetes H2 may exert a hypoglycemic effect, which can be normalized by patients lowering their insulin injection levels. So it is important to monitor glucose and insulin for diabetics.

The short answer is no. The longer explanation is this: Dextrose is present in the tablet as a binding agent, in a minuscule amount. It amounts for a fraction of a calorie and is not used as a sweetener.

 No. The levels of magnesium in the Rejuvenation tablet are too low to be flammable, as is the level of hydrogen in the water created. Hydrogen has to exceed 4% of the atmospheric pressure to be explosive.

Rejuvenation is by far the most powerful hydrogen creator on the market. Capable of producing enough H2 to saturate 500ml of water with 13 PPM*(parts per million) of H2, this far exceeds what any of the other methods can achieve. By contrast, both ionizers and hydrogen sticks typically produce between 0.1-0.5 PPM of H2, while degrading in performance over time. Ingestible tablets give off a constant H2 level, which has shown to be ineffective in some disease models(such as Parkinson’s), and the competing tablets produce only a fraction of the total H2 as Rejuvenation on account of lower active ingredients and an inefficient design. Many of the best human studies have relied on labs creating H2 water in excess of 4-6 PPM, so Rejuvenation is the only reliable choice!

While popular in some circles for claimed therapeutic benefits for specific ailments, food grade hydrogen peroxide [H2O2] is in no way similar to dissolved molecular hydrogen [H2] other than they both contain the word ‘hydrogen’. Hydrogen peroxide is a strong oxidizer and is used as a bleaching agent and disinfectant. Molecular hydrogen [H2] is a reducing agent/anti-oxidant.


Hydrogen rich water is regular water that has been saturated with molecular hydrogen, or hydrogen gas (H2). Water, or H2O, is a chemical compound consisting of 2 hydrogen atoms (H) bonded with an oxygen atom (O). Hydrogen-rich water is a solution of H2 (molecular hydrogen) gas, that is simply dissolved in to H2O (water). Think of ‘carbonating’ water, used in sparkling waters and soda pops, but instead of using CO2 (carbon dioxide) gas, using H2 (molecular hydrogen) gas.

Some people enjoy adding lemon or lime juice to the water for taste. It may also slightly increase retention in an open cup, and will increase saturation in a sealed bottle.

The best way to prepare this is to prepare the water with the cap off for the beginning of the reaction. Wait until the tablet is roughly 80% reacted, and then seal the bottle and shake until it finishes. Take with you to go, waiting at least 5 minutes for the external pressure to saturate the H2 into the water and reach a new equilibrium.

The tablet has been refined and maximized to achieve the highest levels of h2 while being prepared in an open cup. See the 'how it works' and 'h2blue' sections for more details. The only reason to use a sealed bottle is if you want to take your h2 water to go.

While any type of water will work, with no difference between filtered, distilled, or tap, we recommend you do not use high pH water from an ionizer or other method. The reaction to create H2 relies on delicate chemistry, and using high pH water, such as '9.5' pH water from an ionizer, will reduce the amount of hydrogen created. For best results use water as close to 7 pH as possible.
