A curated collection of scientific publications, brochures, and expert reports on molecular hydrogen (H₂) – as drinking water, for inhalation, and for therapeutic applications. For over 15 years, we at AQUACENTRUM have been working with molecular hydrogen (H₂) – as drinking water, for inhalation, and in its diverse therapeutic forms. During this time, we have amassed an extensive collection of scientific studies, […]
> The most important FAQ's about alkaline water
What is hydrogen water or water containing hydrogen (hydrogen rich water)?
Hydrogen-enriched water (H₂ water) is drinking water enriched with molecular hydrogen and is gaining increasing importance in the health and wellness sector. Over 1.000 scientific studies indicate that it can reduce oxidative stress in the body and thus support processes such as cell protection and regeneration. Users report increased well-being, greater mental clarity, and noticeable freshness—[…]
What measurable value does optimal ionized hydrogen water have and are ionization and alkalinization linked? Which water do you recommend?
Pankaia K.: You hear a lot about ionization. Is there a device that can measure ionization? Is there a scale? What is the value of non-ionized hydrogen water? Now you're asking for a scale because you want to rate the water to decide what you should drink. Unfortunately there are 3 scales, but […]
Redox potential
Armin K.: Why do you actually need to measure the redox potential of the alkaline activated water if you have already determined the pH value? There is the Nernst equation for conversion?
HRW – Hydrogen Rich Water
Heinrich H.: The US researcher Tyler Le Baron writes that the dissolved hydrogen content is the sole therapeutic advantage of activated water, even if he drinks mildly alkaline water from a water ionizer in about the same drinking range as you, i.e. between pH 8 and 9 recommends. Now if I'm not overly acidic because I [...]
What is a hydrogen booster or hydrogen booster?
The Hydrogen Booster – a portable water ionizer for producing hydrogen-rich water from any water source. Measuring hydrogen content: Drop test and shake test. Drop test (precise measurement): One drop of the measuring liquid corresponds to approximately 0,1 ppm. The H2 Turbo 3.0 achieves approximately 50 drops in 5-minute mode – that is, around 5 ppm. With a 1-liter bottle and a 30-minute runtime, even 70 to 80 ppm are possible.
What is Kangen® Water?
As of 2026 · From AQUACENTRUM Water Retailers since 2007: Kangen Water is alkaline activated water produced by Japanese Leveluk™ devices from the company Enagic. The term has been trademarked since 2005. In this guide, you will learn everything about its effects, production, prices, measurements, and what truly distinguishes Kangen Water from other activated waters—including a direct hydrogen measurement comparison between the Kangen K8, […]
Does it make sense to buy a pH redox combination meter?
pH redox combination meter?
Increased calcium content in alkaline activated water?
Increased calcium content in alkaline activated water? Eberhard P.: In your video lecture “The Redox Revolution” you talk about an increased calcium content in alkaline activated water. You can also see this on the bottles when a whitish limescale separates after a while. I really believe in drinking active water, but isn't there a risk of hardening of the arteries if I drink it constantly [...]
Value comparison °dH (degree of German hardness), mmol/l, mg/l.
Frieda S.: When you recommend water ionizers, you always state the hardness levels in 0dH (degree of German hardness). However, my drinking water supplier's analysis states mmol/l. On the other hand, mineral water bottles say mg/l. How can these values be compared?
Can alkaline water neutralize stomach acid?
How does alkaline water survive stomach acid to have an alkaline effect in the body? The question about the alkaline effect in view of stomach acid is answered as the first question in the interview video: And here is the experiment with stomach acid, which cannot be diluted so easily: You can drink alkaline active water in the recommended drinking range up to pH 9,5 to […]
Alkaline water – activated water – ionized water: what is what?
Herrmann K.: Alkaline water, alkaline activated water, ionized water, electro-activated drinking water, electrolyte water, hydrogen-rich water... I'm starting to no longer know my way around. Which water do you recommend and which is which? When water is electrolyzed in an electrolytic cell with a diaphragm membrane, the two water ions H+ and OH- are not only formed from water molecules. It […]
