With its antioxidant properties, hydrogen gas (H2) has been evaluated in vitro, in animal studies and in human studies for a broad range of therapeutic indications. A simple search of “hydrogen gas” in various medical databases resulted in more than 2000 publications related to hydrogen gas as a potential new drug substance. A parallel search in clinical trial registers also generated many hits, r

It is known that molecular hydrogen is a relatively stable, ubiquitous gas that is a minor component of the atmosphere. At the same time, in recent decades molecular hydrogen has been shown to have diverse biological effects. By the end of 2022, more than 2000 articles have been published in the field of hydrogen medicine, many of which are original studies. Despite the existence of several review

As diabetes rates surge globally, there is a corresponding rise in the number of patients suffering from diabetic kidney disease (DKD), a common complication of diabetes. DKD is a significant contributor to chronic kidney disease, often leading to end-stage renal failure. However, the effectiveness of current medical treatments for DKD leaves much to be desired.

Over the last two decades, a plethora of disease models and human studies have confirmed the beneficial effects of molecular hydrogen (H2), a simple biotherapeutic gas. Recent small-scale studies evaluating the effects of hydrogen-rich water (HRW) on various metabolic conditions pointed to advantageous effects of HRW in regulating blood lipid profiles. However, to the best of the authors’ knowledge,

Oxidative stress is one of the major causes of most age-dependent neurodegenerative disorders. Neurons accumulate oxidative damage over time due to post-mitotic cells. Thus, modulation of oxidative stress is essential to overcome these disorders. Molecular hydrogen (H2) has great potential for treating various diseases and improving quality of life by exerting multiple functions including anti-oxi

Age-related diseases represent the largest threat to public health. Aging is a degenerative, systemic, multifactorial and progressive process, coupled with progressive loss of function and eventually leading to high mortality rates. Excessive levels of both pro- and anti-oxidant species qualify as oxidative stress (OS) and result in damage to molecules and cells. OS plays a crucial role in the dev

Numerous benefits have been attributed to alkaline-electrolyzed–reduced water (ERW). Sometimes these claims are associated with easily debunked concepts. The observed benefits have been conjectured to be due to the intrinsic properties of ERW (e.g., negative oxidation–reduction potential (ORP), alkaline pH, H2 gas), as well enigmatic characteristics (e.g., altered water structure, microclusters, fre

Many studies demonstrate the safety of alkaline-electrolyzed–reduced water (ERW); however, several animal studies have reported significant tissue damage and hyperkalemia after drinking ERW. The mechanism responsible for these results remains unknown but may be due to electrode degradation associated with the production of higher pH, in which platinum nanoparticles and other metals that have harmf

Hydrogen gas (molecular hydrogen, H2) has significant effects in a range of organisms, from plants to humans. Many inert gases have been reported to have similar effects, and such responses may be most pronounced when cells are stressed. Xenon (Xe), for example, is a well-known anesthetic. The direct targets of these gases, in most cases, remain elusive. Myoglobin and hemoglobin are known for their

Background: Hydrogen rich water (HRW) was used as an auxiliary treatment for periodontitis and peri-implantitis due to its good antioxidant properties. However, the stability of artificially added active hydrogen was far less than that of pure natural active hydrogen, which greatly reduced active hydrogen molecules number in HRW. Meanwhile, the effect of HRW was relatively slow. Finally, long-term

Diatomic hydrogen (H2) is the lightest and most abundant molecule in the universe. Hydrogen's reactivity with oxygen is well recognized as a thermodynamically favorable redox reaction that forms water. H2's small size results in unsurpassed diffusivity (even diffusing through steel), enabling it to reach therapeutic targets effectively even in low-flow states. In vivo, inhaled H2 undergoes solubil
