Consumption of hydrogen-rich water (HRW) has been shown to have anti-inflammatory and metabolic-modulatory benefits. A randomized, placebo-controlled trial was conducted to assess the potential blood uric acid-lowering effects of HRW consumption with different doses (low and high doses) and duration (4 and 8 weeks) in patients with hyperuricemia. The Placebo group consumed three bottles of ordinary drinking water (330 mL …
Hydrogen inhalation for reactive oxygen stress
Reactive Oxygen Species (ROS) play a key role in physiological processes. However, the imbalance between ROS and antioxidants in favor of the former causes oxidative stress linked to numerous pathologies. Due to its unique attributes, including distinguished permeability and selective antioxidant capability, molecular hydrogen (H2) has become an essential therapeutic agent. Hydrogen Inhalation Therapy (HIT) has come to light as …
Hydrogen-rich water and metabolic syndrom
Metabolic syndrome is associated with several medical risk factors including dyslipidemia, hyperglycemia, and obesity, which has become a worldwide pandemic. The sequelae of this condition increase the risk of cardiovascular and neurological disease and increased mortality. Its pathophysiology is associated with redox dysregulation, excessive inflammation, and perturbation of cellular homeostasis. Molecular hydrogen (H2) may attenuate oxidative stress, improve cellular function, …
Hydrogen-rich water attenuates pre-diabetic DNA oxidative injuries
Hydrogen-rich water is conventionally prepared by direct current-electrolysis, but has been not or scarcely prepared by alternating current (AC)-electrolysis. The AC preparations from tap water for 20-30 minutes exhibit a dissolved hydrogen concentration of 1.55 mg/L, which was close to the theoretical maximum value of 1.6 mg/L. These preparations also displayed an oxidation-reduction potential of -270 mV (tap water: +576 …
Breath hydrogen produced by ingestion of commercial hydrogen water
This study compared how and to what extent ingestion of hydrogen water and milk increase breath hydrogen in adults. Five subjects without specific diseases, ingested distilled or hydrogen water and milk as a reference material that could increase breath hydrogen. Their end-alveolar breath hydrogen was measured. Ingestion of hydrogen water rapidly increased breath hydrogen to the maximal level of approximately …
Hydrogen-rich water decreases serum LDL-cholesterol levels and improves HDL function
Authors have found that hydrogen (dihydrogen; H2) has beneficial lipid-lowering effects in high-fat diet-fed Syrian golden hamsters. The objective of this study was to characterize the effects of H2-rich water (0.9-1.0 l/day) on the content, composition, and biological activities of serum lipoproteins on 20 patients with potential metabolic syndrome. Serum analysis showed that consumption of H2-rich water for 10 weeks …
Molecular hydrogen consumption in the human body during the inhalation of hydrogen gas
Inhaling or ingesting hydrogen (H2) gas improves oxidative stress-induced damage in animal models and humans. It has been previously reported that H2 was consumed throughout the human body after the ingestion of H2-rich water and that the H2 consumption rate (VH2) was 1.0 μmol/min/m(2) body surface area. To confirm this result, authors evaluated VH2 during the inhalation of low levels …
Hydrogen-rich water improves lipid and glucose metabolism in patients with type 2 diabetes
Oxidative stress is recognized widely as being associated with various disorders including diabetes, hypertension, and atherosclerosis. It is well established that hydrogen has a reducing action. We therefore investigated the effects of hydrogen-rich water intake on lipid and glucose metabolism in patients with either type 2 diabetes mellitus (T2DM) or impaired glucose tolerance (IGT). We performed a randomized, double-blind, placebo-controlled, …
Effectiveness of hydrogen rich water in subjects with potential metabolic syndrome
Metabolic syndrome is characterized by cardiometabolic risk factors that include obesity, insulin resistance, hypertension and dyslipidemia. Oxidative stress is known to play a major role in the pathogenesis of metabolic syndrome. The objective of this study was to examine the effectiveness of hydrogen rich water (1.5-2 L/day) in an open label, 8-week study on 20 subjects with potential metabolic syndrome. …
