Hydrogen-rich water is ordinary water (H₂O) in which gaseous dihydrogen molecules (H₂) have been dissolved. Its basic chemical composition does not change. What changes is the presence of millions of free hydrogen molecules capable of crossing all biological barriers in your body without exception: cell membranes, mitochondria, and the blood-brain barrier.
Tap water contains less than 1 ppb (part per billion) of dissolved H₂. A quality hydrogen water generator produces between 1,000 and 5,000 ppb. It is this high concentration of active H₂ that produces the effects documented in clinical studies. Below 500 ppb, no measurable biological effect is observed.
No. These are two distinct products with different biological mechanisms. Alkaline water changes the pH of the water. Hydrogen-rich water introduces active H₂ molecules into the body. The levels of scientific evidence are very unequal: the literature on H₂ has over 1,700 medical publications compared to very few for alkaline water.
Once ingested, H₂ molecules immediately cross all biological barriers thanks to their nanometric size. They specifically neutralize hydroxyl radicals (•OH), the most destructive free radicals for your cells, without disturbing the radicals useful for cell signaling. They also activate the Nrf2 pathway, which stimulates the natural production of your endogenous antioxidants, including glutathione and superoxide dismutase.
The systematic review by Dhillon et al. (2024), analyzing 25 clinical studies conducted on humans, confirms documented antioxidant and anti-inflammatory effects. The most well-established benefits are accelerated athletic recovery with reduced blood lactate (Aoki et al., 2012), more stable daily energy, reduced chronic inflammation, and improved mental clarity.
Yes. H₂ has been used for over 80 years in professional deep-sea diving without any documented toxicity. It is classified as GRAS (Generally Recognized As Safe) by the US FDA. No drug interactions are currently reported. As a precaution, pregnant women and people undergoing medical treatment should consult their doctor before use.
The first effects on energy and digestion generally appear between 7 and 14 days of regular daily consumption. Effects on athletic recovery, skin, and mental clarity consolidate between 3 and 4 weeks. Consistency is the non-negotiable condition for any result.
The minimum threshold documented in clinical studies is 500 ppb. The optimal range is between 1,000 and 3,000 ppb. Below 500 ppb, no measurable biological effect is observed regardless of consumption regularity.
The reference formula is 30 to 40 ml per kilogram of body weight per day. For a 70 kg adult, this represents between 2.1 and 2.8 liters. For athletes or people with high oxidative stress, this volume can be increased up to 3 to 4 liters.
Both options exist. Hermetic cans sold in pharmacies can contain correct concentrations, but their cost for daily use is prohibitive, between €90 and €240 per month. A quality hydrogen-rich water generator represents a one-time investment that pays for itself in less than a month, while ensuring fresh water produced on demand, at maximum concentration at the time of consumption.
Three criteria are non-negotiable. The SPE/PEM dual chamber technology, which guarantees pure H₂ without oxidizing by-products in the water. A certified concentration greater than 1,000 ppb by an independent laboratory. A European CE certification.

It's not a supplement. Not a drug. Just water, but not just any water.
I was looking for a 100% natural solution to optimize my recovery. I discovered hydrogen water and it changed everything. Less inflammation, more energy, top concentration. Today, it's my routine. Every day, without exception.
