Initiation and progression of periodontal disease include oxidative stress. Systemic application of antioxidants may provide clinical benefits against periodontal disease including gingivitis. Recently, a jelly containing a high concentration of hydrogen (40 ppm) was developed. We hypothesized that oral intake of this hydrogen-rich jelly may be safe and effective on gingivitis. This clinical trial was designed to investigate the safety …
Hydrogen-rich water for cage density stress
This study investigated the impact of drinking hydrogen-rich water (HRW) on growth performance, organ weights, thiol/disulphide homeostasis, oxidative status and some hormonal, histopathological and immunohistochemical changes in rats fed in a restricted housing environment. The eight groups (each group [male/female] eight rats) comprised two control, two hydrogen, two stress and two stress + hydrogen. All animals were given feed and …
Hydrogen-rich water affects milk properties
This study aimed to investigate the effects of hydrogen-rich water (HRW) consumption in goats on the chemical composition, antioxidant activity, total phenolic content, in vitro antidiabetic activity (α-amylase and α-glucosidase inhibitions), free fatty acid profile, and volatile compounds of colostrum and mature milk. Goats were fed ad libitum with either normal water (NW) or HRW for 20-22 days before and …
Protective effect of hydrogen-rich water on spermatogenesis
Obesity can impair spermatogenesis by various mechanisms such as decreased sperm concentration and increased oxidative DNA damage. Hydrogen-rich water (HRW) possesses therapeutic antioxidant properties that may help offer protection to sperm. This study aimed to investigate the therapeutic potential of HRW on spermatogenesis dysfunction in rats with high-fat diet (HFD)-induced obesity. In this experiment, thirty male Wistar Albino rats were …
Hydrogen for stem cell regeneration
Mesenchymal stem cells (MSCs) are properties of self-renewal and differentiation potentials and thus are very appealing to regenerative medicine. Nevertheless, their therapeutic potential is frequently constrained by senescence, limited proliferation, and stress-induced apoptosis. The key role of the p53-p21 biology in MSC biology resides in safeguarding genomic stability while promoting senescence and limiting regenerative capacity upon over-activation demonstrated. This pathway …
Hydrogen-rich water for retinal degeneration
Long-term spaceflight can lead to changes in eye structure and decreased visual function. At present, there are almost no effective methods to prevent and treat eye damage caused by microgravity environments. Oxidative stress has been identified as one of the contributing mechanisms of spaceflight-associated neuro-ocular syndrome (SANS), and hydrogen (H2) has demonstrated significant antioxidant and anti-inflammatory effects. The aim of …
Dual benefits of hydrogen gas inhalation and hydrogen-enriched dialysate
The combination of H₂ gas inhalation and H₂-enriched dialysate offers a novel and promising approach to managing oxidative stress and improving the quality of life in patients on HD. However, further research is essential to optimize treatment protocols, ensure safety, and develop comprehensive clinical guidelines for the widespread adoption of this therapy.

Hydrogen for skin autoimmune disorders
AGEs are molecules formed by nonenzymatic glycation of proteins, lipids, and nucleic acids, a process accelerated under hyperglycemic conditions such as DM1. These molecules interact with specific receptors, particularly the Receptor for AGEs (RAGE), triggering intracellular signaling cascades that promote oxidative stress through the generation of Reactive Oxygen Species (ROS) and activation of inflammatory pathways. A critical pathological mechanism involves …
Hydrogen-rich saline against hemorrhagic shock
The endothelial glycocalyx is a gel-like layer on the vascular endothelial surface that is crucial for maintaining vascular homeostasis. Massive bleeding leads to the shedding of the glycocalyx, which can lead to vascular leakage during fluid administration. Recently, the beneficial effect of hydrogen inhalation in the treatment of hemorrhagic shock has been reported. However, the efficacy of hydrogen-rich saline in …
Magnesium-assisted hydrogen for heart failure
Heart failure (HF) is a leading cause of mortality among patients with cardiovascular disease and is often associated with myocardial apoptosis and endoplasmic reticulum stress (ERS). While hydrogen has demonstrated potential in reducing oxidative stress and ERS, recent evidence suggests that magnesium may aid in hydrogen release within the body, further enhancing these protective effects. This study aimed to investigate …
