role of molecular hydrogen H2 water in the regression of HYPERCHOLESTEROLEMIA and ATHEROSCLEROSIS



We have found that hydrogen (dihydrogen [H2] (water)) decreases plasma low-density lipoprotein (LDL) cholesterol levels and improves high-density lipoprotein (HDL) function in patients with potential metabolic syndrome in a before-after self-controlled study.


The purpose of this study was to further characterize the effects of H2-rich water (0.9 L/day) on the content, composition, and biological activities of plasma lipoproteins on patients with hypercholesterolemia and their underlying mechanisms in a double-blinded, randomized, and placebo-controlled trial.


This was a case-control study.


The setting was the Zhoudian community, Tai’an, China.


A total of 68 patients with untreated isolated hypercholesterolemia were randomly allocated to either drinking H2-rich water (n = 34) or placebo water (n = 34) for 10 weeks.


HDL isolated from the H2 hydrogen water group showed an increased ability to promote the ATP-binding cassette transporter A1-mediated cholesterol efflux ex vivo. Plasma pre-β-HDL levels were up-regulated although there were no changes in plasma HDL-cholesterol levels. Moreover, other HDL functions, assessed in protection against LDL oxidation, inhibition of oxidized-LDL-induced inflammation, and protection of endothelial cells from oxidized-LDL-induced apoptosis, were all significantly improved by H2 hydrogen water  treatment. In addition, molecular hydrogen water H2 treatment increased the effective rate in down-regulating plasma levels of total cholesterol (47.06% vs 17.65%) and LDL cholesterol (47.06% vs 23.53%). Western blot analysis revealed a marked decrease in apolipoprotein B100 and an increase in apolipoprotein M in plasma of the molecular hydrogen water H2 group. Finally molecular hydrogen water H2 treatment resulted in a significant reduction in the levels of several inflammatory and oxidative stress indicators in whole plasma and HDL particles.


H2 hydrogen water  activates ATP-binding cassette transporter A1-dependent efflux, enhances HDL antiatherosclerotic functions, and has beneficial lipid-lowering effects. The present findings highlight the potential role of H2 hydrogen water in the regression of hypercholesterolemia and atherosclerosis.

molecular hydrogen water improves lipid and glucose metabolism in patients with TYPE 2 DIABETES or impaired glucose tolerance

Supplementation of molecular hydrogen-rich water improves lipid and glucose metabolism in patients with type 2 diabetes or impaired glucose tolerance.

It is well established that molecular hydrogen (water) has a selective oxidation/free radical reducing action.

Oxidative stress is recognized widely as being associated with various disorders including diabetes, hypertension, and atherosclerosis.

We therefore investigated the effects of molecular 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, crossover study in 30 diabetes patients with T2DM controlled by diet and exercise therapy and 6 patients with IGT.

The diabetes patients consumed either 900 mL/d of  hydrogen-rich pure water or 900 mL of placebo pure water for 8 weeks, with a 12-week washout period. Several biomarkers of oxidative stress, insulin resistance, and glucose metabolism, assessed by an oral glucose tolerance test, were evaluated at baseline and at 8 weeks.

Intake of  hydrogen-rich water was associated with significant decreases in the levels of modified low-density lipoprotein (LDL) cholesterol (ie, modifications that increase the net negative charge of LDL), small dense LDL, and urinary 8-isoprostanes by 15.5% (P < .01), 5.7% (P < .05), and 6.6% (P < .05), respectively.

Hydrogen-rich water intake was also associated with a trend of decreased serum concentrations of oxidized LDL and free fatty acids, and increased plasma levels of adiponectin and extracellular-superoxide dismutase. In 4 of 6 patients with IGT, intake of molecular hydrogen-rich water normalized the oral glucose tolerance test.

In conclusion, these results suggest that supplementation with molecular hydrogen-rich water may have a beneficial role in prevention of T2DM and insulin resistance.

molecular hydrogen water for patients with pressure ulcer – effects on normal human SKIN WOUNDS

Pressure ulcer (PU) is common in immobile elderly patients, and there are some research works to investigate a preventive and curative method, but not to find sufficient effectiveness. The aim of this study is to clarify the clinical effectiveness on wound healing in patients with pressure ulcer PU by molecular hydrogen-dissolved in water (HW) intake via tube-feeding (TF). Furthermore, normal human dermal fibroblasts OUMS-36 and normal human epidermis-derived cell line HaCaT keratinocytes were examined in vitro to explore the mechanisms relating to whether molecular hydrogen plays a role in wound-healing at the cellular level.

22 severely hospitalized elderly Japanese patients with pressure ulcer PU were recruited in the present study, and their ages ranged from 71.0 to 101.0 (86.7 ± 8.2) years old, 12 male and 10 female patients, all suffering from eating disorder and bedridden syndrome as the secondary results of various underlying diseases. All patients received routine care treatments for pressure ulcer PU in combination with molecular hydrogen water HW intake via TF for 600 mL per day, in place of partial moisture replenishment. On the other hand, HW was prepared with a hydrogen-bubbling apparatus which produces molecular hydrogen water HW with 0.8-1.3 ppm of dissolved hydrogen concentration (DH) and −602 mV to −583 mV of oxidation-reduction potential (ORP), in contrast to reversed osmotic ultra-pure water (RW), as the reference, with DH of < 0.018 ppm and ORP of +184 mV for use in the in vitro experimental research. In in vitro experiments, OUMS-36 fibroblasts and HaCaT keratinocytes were respectively cultured in medium prepared with molecular hydrogen water  HW and/or reversed osmotic ultra-pure water RW. Immunostain was used for detecting type-I collagen reconstruction in OUMS-36 cells. And intracellular reactive oxygen species (ROS) were quantified by NBT assay, and cell viability of HaCaT cells was examined by WST-1 assay, respectively.


22 patients were retrospectively divided into an effective group (EG, n = 12) and a less effective group (LG, n = 10) according to the outcomes of endpoint evaluation and the healing criteria. Pressure Ulcers  hospitalized days in EffectiveGroup were significantly shorter than in LessseffectiveGroup (113.3 days vs. 155.4 days, p < 0.05), and the shortening rate was approximately 28.1%. Either in EG or in LG, the reducing changes (EG: 91.4%; LG: 48.6%) of wound size represented statistically significant difference versus before molecular hydrogen water HW intake (p < 0.05, p < 0.001). The in vitro data demonstrate that intracellular ROS as quantified by NBT assay was diminished by molecular hydrogen water HW, but not by reverse osmosys water ultraviolet-A (UVA)-irradiated HaCaT cells. Nuclear condensation and fragmentation had occurred for UVA-irradiated HaCaT cells in reverse osmosis water RW, but scarcely occurred in molecular hydrogen water HW as demonstrated by Hoechst 33342 staining. Besides, under UVA-irradiation, either the mitochondrial reducing ability of HaCaT cells or the type-I collagen construction in OUMS-36 cells deteriorated in reverse osmosis water  RW-prepared culture medium, but was retained in molecular hydrogen water HW-prepared culture medium as shown by WST-1 assay or immunostain, respectively.


molecular hydrogen water HW intake via TF was demonstrated, for severely hospitalized elderly patients with PressureUlcers, to execute wound size reduction and early recovery, which potently ensue from either type-I collagen construction in dermal fibroblasts or the promoted mitochondrial reducing ability and ROS repression in epidermal keratinocytes as shown by immunostain or NBT and WST-1 assays, respectively.


PressureUlcer is common in the immobile elderly or other immobile patients suffering from diseases such as spinal cord injury, amyotrophic lateral sclerosis, multiple sclerosis, and muscular dystrophy, etc. Furthermore, aged and weak bedridden patients belong to a high risk population for Pressure Ulcers [1]. It is estimated that there are over one million elderly people who are suffering from the skin peculiarity and are facing the risk factors of Pressure Ulcers in USA [2]. Fundamentally, it is usually pointed out that social, psychological and financial expenses for Pressure Ulcers are immeasurable, patients and their families as well as health care providers are always receiving the mental strain [3].

For Pressure Ulcers , it is a primary research task to explore a cheap but effective preventive and curative method. Although various methods for prevention and treatment have been developed, they are far from sufficiently succeeding. While slightly delayed, basic studies are seen to steadily proceed in the same way as the clinical study. As the basic studies for wound healing, a lot of researchers are focusing on skin-constructing proteins such as collagen, elastin, laminin and fibronectin, and on metabolic activity and proliferating ability of dermal fibroblasts [45].

In relation to this matter, we had confirmed the fact that molecular hydrogen-dissolved in water HW, as an external use for skin, can promote the construction of the type-I collagen in fibroblastic cells of dermis [678]. We prepared molecular hydrogen-dissolved in water HW with a hydrogen-bubbling apparatus, exhibited a DH of 1.13 ppm and an ORP of −741 mV, in contrast a DH of < 0.01 ppm and an ORP of +150 mV for normal water [6]. Simultaneously, normal human dermal fibroblasts OUMS-36 and normal human epidermis-derived keratinocytes HaCaT were cultured using an immunostain, in addition, WST-8 and DAPI stains were conducted to examine the cytoprotective effects of molecular hydrogen-dissolved in water HW against UVA-ray irradiation. Six Japanese subjects were enrolled in a trial of molecular hydrogen water HW-bathing (DH, 0.2-0.4 ppm) every day for 3 months. The results obtained showed that molecular hydrogen water  HW-bathing significantly improved wrinkles on the back of the neck in four subjects on 90th day as compared to day 0. Thus the conclusion was achieved, in which molecular hydrogen water  HW can serve as a daily skin care routine to repress UVA-induced skin damages by ROS-scavenging and promotion of type-I collagen synthesis in dermis. On the other hand, many basic research studies demonstrated that molecular hydrogen water HW is widely applied to various diseases, as an oral intake for absorbing via the gastrointestinal tract [91011121314]. The researches obviously suggest that whether using a bathing type or oral intake type of treatment,molecular hydrogen water HW is still an effective method to repair the skin and scavenge the ROS [151617].

We theorized that a routine care treatment in combination with molecular hydrogen water  HW intake via TF for patients with PressureUlcers may improve wound healing and maintain a better health condition than before. The purpose of this study is to clarify the clinical effectiveness of wound healing for patients with PressureUlcers by means of an oral intake of molecular hydrogen water  HW via TF. Furthermore, OUMS-36 cells and HaCaT cells were examined to analyze the mechanisms relating to whether molecular hydrogen water  plays a role in wound healing at the cellular level, in vitro.


Clinical materials


Medical record data that were analyzed for this study were obtained from twenty-two elderly Japanese patients with Pressure Ulcers who were hospitalized and institutionalized in Kobayashi Hospital, Fukuyama City, Hiroshima Prefecture, Japan, which is a general hospital attached to a mixed long-term care facility. This study was approved by the Ethics Committee of Kobayashi Hospital.

The ages of PressureUlcers patients who we treated in this study ranged from 71.0 to 101.0 (86.7 ± 8.2) years old, and ten patients were women. On the time of admission, they had suffered from one or multiple diseases and complications, and almost all of them were bedridden elderly people at a high risk of PressureUlcers development, and all of them could not eat without other people’s aid. On the time of admission or during the hospitalization, all patients had been or were gradually appearing symptoms of PressureUlcers.

The types of diseases and complications in these patients, not only included eating disorder but 90% also showed the prevalence of being in the aged period, and 100% had impaired mobility. However, it must be emphasized that PressureUlcers incidence of new onset in Kobayashi Hospital remained approximately 2.10% in 2010–2011, persisted in low level. Because it was reported that average PressureUlcer incidence was 2.43% in a nationwide survey executed by Japanese Society of Pressure Ulcers [18].

Twenty-two patients were retrospectively grouped into EG (effective group, n = 12) and LG (less effective group, n = 10) according to the outcomes of endpoint evaluation and the healing criteria. Details with regard to the discharge from hospital for whether cure or not were analyzed, and baseline data were summarized (Table 1). In data processing, results of all patients were classified as stage I-IV according to the Guideline in 2009 of EPUAP (European Pressure Ulcer Advisory Panel) & NPUAP (National Pressure Ulcer Advisory Panel) that is used as assessment for the severity of PressureUlcers. Coincidentally, all patients in this study belonged to stage II or III.

Clinical care treatments

Hospitalized routine care treatment

The treatment focused on preventing PressureUlcers from getting worse and on restoring healthy skin. According to the routine care treatments for all patients, nonsurgical therapies were selected, such as ointment, gauze dressing, wrapping, and bed-pad were used after washing by the acidic water disinfection. The skin care, pressure relief and nutritional support were aggressively used as a part of this care treatment [13]. The main care steps to treat PressureUlcers included:

  1. a.

    Managing the tissue load.

  2. b.

    Keeping the ulcer area clean and covered, and not letting it dry out.

  3. c.

    Body-position changes at least every 2 hours if the patient is confined to a bed, or as often as every 15 min if sitting in a wheelchair.

  4. d.

    To achieve positive nutritional nitrogen balance, patient consumed by TF approximately 30 to 35 calories per kg per day and 1.25 to 1.50 g of protein per kg per day.

Preparation for molecular hydrogen water HW

HW molecular hydrogen water was prepared with a molecular hydrogen-bubbling apparatus which consists mainly of a water supply section for manufacturing reverse osmosis water RW with less 0.018 ppm of DH and +184 mV of ORP, and molecular hydrogen water  HW with 0.8-1.3 ppm of DH and −602 mV to −583 mV of ORP. For comparing molecular hydrogen water  HW with reverse osmosys water RW, the water characteristic parameters were measured with the different dilution rates (Table 2, Figures 1 and 2). It must be emphasized that some stable characteristic indicators and the proprieties for innocuity and harmlessness of molecular hydrogen water were obtained from several separated in vivo and human experiments which we had reported [1920212223]. Meanwhile, via tube-feeding, Pressure Ulcers  patients were enforced to intake molecular hydrogen  water HW of 600 mL per day, in the morning and afternoon for approximately one hour, respectively, immediately after molecular hydrogen  water HW was manufactured everytime.

Measurement results of diluting molecular hydrogen  water HW with reverse osmosys water RW. The dilution rates are showed as Figure 1. Figures 1a and –b show the ever-increasing tendencies on DO (dissolved oxygen concentration) and ORP (oxidation-reduction potential). Meanwhile, as shown by Figures 1c and –d, DH (dissolved hydrogen concentration) shows the ever-decreasing tendency which indicates the dissolved hydrogen in the hydrogen water was evaporated slowly by mixing with normal regular water. On the other hand, both molecular hydrogen  water HW with reverse osmosys water RW have been holding the temperature range of 23.2-24.1°C and pH 7.37-7.48 no matter from 1 to 11-fold dilution rate.

Clinical evaluations

The evaluative indices for clinical therapeutic effects on PRESSURE ULCERS consisted of the hospitalized days, wound size, classifications of PressureUlcers-stage and DESIGN- rating.

Hospitalized days

Because the increased length of hospitalized stay is an important index for a PressureUlcers patient of QOL (Quality of Life), the days from admission to discharge for twenty-two patients were counted.

Wound size

For obtaining precise objective information and monitoring the healing degree about wound, the medical-care staff measured the size, depth and area [24], utilized photography and diagrams for recording the shape and outline of the wound.

Classifications of PressureUlcers-stages

According to a well-known Panel Guideline established by EPUAP and NPUAP in 2009 [3], stage II includes the partial thickness for loss of skin involving epidermis, dermis or both. The ulcer is superficial and presents clinically as an abrasion or blister, but is not deeper than the dermis. On the other hand, stage III involves the full depth of the skin, and may extend into the subcutaneous tissue layer which has a relatively poor blood supply and can be difficult to heal [2526].


DESIGN was an absolute evaluation tool and consumed as a clinical indicator to assess the quality of medical care. But, its score could not be compared the severity of PressureUlcers among different patients and their various ulcers. Because of this, the DESIGN-rating was invented to use as a simple and easy assessment of PressureUlcers [2728]. In our study, the DESIGN-rating score of every patient was recorded by the medical-care staff, at least once monthly.

In vitro experiments

Materials and methods

Normal human dermal fibroblastic cells OUMS-36

OUMS-36 cells were cultivated for 18 hours in molecular hydrogen  water HW or reverse osmosys water RW-prepared Dulbecco’s modified Eagle’s medium (DMEM; Nissui Pharmaceutical Co. Ltd., Tokyo) supplemented with 10% FCS (fetal calf serum) (GIBCO) in a CO2incubator to be kept at 37°C and pH 7.1-7.4 in a moistened atmosphere of 5% CO2. The spent medium was replaced by the fresh molecular hydrogen  water HW or reverse osmosys water RW-prepared culture medium, and was at once irradiated with UVA ray at doses of 12 or 18 J/cm2, corresponding to the normal dose range for the human daily life. The resultant cells were stained for the nuclei with 4′,6-diamidino-2-phenylindole dihydrochloride (DAPI, Ultracruz Mounting Medium, sc-24941, Santa Cruz Biotechnology Inc., Santa Cruz, CA), and observed for type-I collagen reconstruction by immunostain using the first antibody directed against type-I collagen and the secondary antibody conjugated with FITC (fluorescein isothiocyanate), as observed with a fluorescence microscope (ECLIPSE E600, Nikon Corp., Tokyo) as previously described [6].

Normal human epidermis-derived keratinocytes HaCaT

HaCaT cells were similarly cultivated in molecular hydrogen  water HW or reverse osmosys water RW-prepared DMEM supplemented with 10% FCS (GIBCO), and similarly UVA-irradiated. The resultant cells were examined for cell viability by WST-1 methods using (phenyl)-5-(2-disulfophenyl)-2H-tetrazolium, monosodium salt as a redox indicator, and for ROS such as superoxide anion radicals by NBT (nitro blue tetrazorium) assay as previously described [6].

Statistical analysis

Either clinical study or in vitro research, the Student’s t-test was used to compare the difference in means ± SD between the control and treated groups using a Microsoft Office Excel 2010 software (Microsoft, Albuquerque, NM, USA) or a software package SPSS 11.0 (SPSS inc., Chicago, IL, USA) for Windows. A p-value that is below 0.05 was regarded to be statistically significant.

The hospitalized days and the DESIGN-rating of PressureUlcers

For the PressureUlcer patients, the hospitalized days in EffectiveGroup were significantly shorter than in LesseffectiveGroup (113.3 days vs. 155.4 days, p < 0.05), and the PressureUlcers reduction rate was approximately 28.1% (Figure 3-a). Likewise, DESIGN-rating in EG was also decreased for comparing the onset with the endpoint (11.5 rates vs. 14.3 rates, p < 0.05) between pre-post evaluations including both in onset (evaluation in the initial time, at the day for the admission to hospital) and in endpoint (evaluation in the last time, at the day for the discharge from hospital or death day). In LG, no statistically significance was seen, in DESIGN-rating indicative of degree of severity for PU, between both of them (Figure 3-b).

Figure 3

Comparison of PU clinical effects for the hospitalized days and the DESIGN-rating in the effective group and in the less effective group. Figure 3a shows the period for the PU hospitalized days in EG was significantly shorter than in LG. Figure 3b indicates that the DESIGN-rating in EG was decreased for comparing the onset with the endpoint. Pre-post evaluations were performed, where the onset and the endpoint were included. All values are statistically compared. Statistical analysis was performed using Student’s t-test, and the significant differences are defined as p < 0.05. The data are presented as the means with the standard deviation (± SD, indicated by the vertical bar). * p < 0.05.

Results of wound size in two groups

Wound measurement is an important means to know the degrees of PU, and its measuring method was demonstrated in Figure 4-a (Figure 4-a). Either in EG or in LG, the reducing changes (EG: 91.4%; LG: 48.6%) of the wound sizes represent a statistically significant difference (p < 0.05, p < 0.001). Similarly, a significant difference is also seen between both EG and LG groups (p < 0.05) (Figure 4-b).

Figure 4

Measurement methods for wound size and results of wound size in the wound-size reductive change between both the groups. Figure 4a demonstrates the wound measurement method. As a protocol, initially, measure the greatest length along the axial direction (head to toe), and then the greatest width along the transverse direction (side to side) using a centimeter ruler. Finally multiply distances of length and width to obtain an estimate of surface area in square centimeters (cm2). Figure 4b indicates a statistically significant difference to the reducing change of wound size in two groups. Some patients had multiple locations for PU. Values are statistically compared. Student’s t-test, *p < 0.05, ***p < 0.001.

Expression of various PU-assessment indices forcing on both stage II and stage III

For observing the clinical effects in many respects, including the hospitalized days, DESIGN-rating and wound size, EG and LG were subdivided to four subgroups according to classifications of PU-stages (see Methods (3)-3). As a result, in stage II, a period for hospitalized days in EG showed significantly shorter than in LG (87.5 days vs. 387.0 days, p < 0.001). Contrary to this, in two group, there was no significance statistically for hospitalized days in stage III (Figure 5-a) owing to diseases other than PU. Moreover, in EG, the DESIGN-rating obtained from subgroups of stage II and stage III depicted a statistically significant difference (p < 0.05) (Figure 5-b). Meanwhile, the diminishment for wound size within subgroups of stage II and stage III presents any statistical differences (Figure 5-c). In a conclusion, stage II and stage III ulcers of EG healed faster and more effectively than those of LG.

Results of a typical case on time-dependent wound-healing progress: for an 85-year-old female patient with PressureUlcer

Figure 6 showed the time-dependent wound-healing progress for an 85-year-old female patient with PressureUlcer. She was admitted to the hospital for suffering from PressureUlcer. Wound findings at onset included: location: sacrum; wound size (cm2): 20.8; stage: II; DESIGN-rating: 16. Four months after routine care treatment plus a combination with molecular hydrogen water HW intake via TubeFeeding, the crater nearly disappeared. Wound findings at endpoint (vs. of onset) included: wound size (cm2): approximately 0 (disappearance); stage: I (improve); DESIGN-rating: 6 (decrease) (Figures 6-a to -d).

Figure 6

Results of a typical case on time-dependent wound-healing progress. An annual time-dependent wound healing progress for an 85-year-old female PressureUlcer patient is reported. She was admitted to the hospital seeking treatment to PressureUlcer. Figure 6a demonstrates photographs for the time-dependent wound-healing progress obtained from the same patient. Figures 6b to –d represent the decreased tendencies of wound size, DESIGN-rating, and stage, respectively.

Results of another typical case on time-dependent wound-healing progress: for an 80-year-old male patient with PressureUlcer

Figure 7 showed the time-dependent wound-healing progress for an 80-year-old male patient with PressureUlcer. His hospitalized period lasted 10 months and it could be divided into the two sub-periods. During the latter 5-month period, he received molecular  HydrogenWater treatment in the addition to the routine care. The outcome shows an improved result (Figures 7-a, -b).

Figure 7

Results of another typical case on time-dependent wound-healing progress. Similarly to Figure 6, Figure 7 also demonstrates a time-dependent wound healing progress, for an 80-year-old male PressureUlcer patient. Figure 7a shows the features photographed at the former period for routine care treatment alone. On the other hand, Figure 7bpresents ones photographed at the latter period for routine care treatment plus molecular Hydrogen Water intake. The latter period in using HydrogenWater intake shows a marked improved outcome.

In vitro experiments

Promotive effects on reconstruction of type-I collagen, as shown by immunostain, on normal human dermal fibroblasts OUMS-36 that were irradiated with UVA ray and then were administered with reverse osmosis water RW- or molecular hydrogen water HW-prepared culture medium, respectively

To study the reconstructive effect of molecular hydrogen water HW on type-I collagen, we used immunostain on OUMS-36 cells that were irradiated with UVA ray and then were administered with reverse osmosis water RW or molecular hydrogen water HW in vitro, respectively. Representative expressions and pixel values were plotted with a software ImageJ (http://rsb.info.nih.gov/ij/). Nuclear condensation (so-called pycnosis) and fragmentation (so-called karyorrhexis) were occurred for UVA-irradiated OUMS-36 cells in reverse osmosis water RW, but scarcely occurred in molecular hydrogen water HW (Figure 8). HW molecular hydrogen water group shows higher proliferation of cells with rounded morphology in fibroblasts and huge morphology, and more abundant in type-I collagen than ones of reverse osmosis water RW group.

Proliferative effects of nucleus-DAPI stain on UVA-irradiated normal human dermal fibroblasts OUMS-36 that were administered with reverse osmosis water RW- or molecular hydrogen water HW-prepared culture medium, respectively

With fluorescence microscopy, DAPI dye can be excited by UVA ray. To examine the reconstructive effect of molecular hydrogen water HW on type-I collagen by immunostain, we also counterstaind nuclei with a DAPI dye in UVA-irradiated OUMS-36 cells for observing the changes when OUMS-36 cells were administered with Reverse osmosis Water or molecular hydrogen water HW in vitro, respectively. Representative expression and relative fluorescence intensity were plotted with the ImageJ. The facilitative effect on nuclear condensation and fragmentation was observed for UVA-irradiated OUMS-36 cells in Reverse osmosis Water , but scarcely occurred in molecular hydrogen water HW as demonstrated by DAPI staining as like the result obtained from immunostain (Figure 9). Through Figure 9-c, the degrees of DAPI stain on HaCaT cells that were irradiated with UVA ray and were administered with  Reverse osmosis Water or molecular hydrogen water HW, respectively, were clarified.

ROS amounts in normal human epidermis-derived keratinocytes HaCaT as quantified by NBT assay

In HaCaT cells, the intracellular ROS amounts were increased in the Reverse osmosis Water -prepared culture medium with UVA-irradiation in different UVA ray doses, but were restored in the molecular hydrogen water HW-prepared culture medium as shown by NBT-stain for superoxide anion radicals. Cell morphology was observed to be more health and less harmful in molecular HydrogenWater than  Reverse osmosis Water (Figure 10).

Elevation of cell viability by pre-irradiational administration with molecular hydrogen-dissolved water to UVA-irradiated HaCaT cells as assessed by mitochondrial dehydrogenase-based WST-1 assay

In HaCaT cells, the cell viability was obviously increased in the molecular hydrogen water HW-prepared culture medium with UVA-irradiation, comparing with reverse osmosis water RW-prepared culture medium by WST-1 assay (Figure 11-d). Cell morphology was also observed to be less vulnerable in terms of diverse symptoms such as cell shrinkage, nuclear condensation and cell fragmentation for molecular hydrogen water HW than reverse osmosis water RW (Figures 11-b, -c). molecular hydrogen water HW group showed higher proliferation of cells with rounded morphology and huge morphology, in HaCaT cells than ones of Reverse osmosis Water group. All of these evidences predicted that molecular  hydrogen-dissolved water may exert cytoprotective effects against UVA ray on HaCaT cells.

The purpose of the present study was to examine the clinical effectiveness of wound healing for Pressure Ulcers using molecular hydrogen water HW intake via TubeFeeding. We have hypothesized that the routine care treatment in combination with molecular hydrogen water HW intake for PressureUlcer patients may improve wound healing, and maintain more healthy condition for them. Furthermore, normal human dermal fibroblasts OUMS-36 and normal human epidermis-derived keratinocytes HaCaT were examined to explore the mechanisms underlying to whether molecular hydrogen plays a role in wound-healing at aspect for cutis tissue, through in vitro experiments.

Our clinical results seem to suggest that molecular hydrogen water  HW oral intake via TubeFeeding is an effective means for wound healing of PressureUlcer patients, who suffered from eating disorder. Despite the limitations caused by practicing our clinical intervention for PressureUlcers, we were able to obtain the improving results in hospitalized days, wound size and other clinical indices by comparing EG with LG. Therefore, we estimated that molecular hydrogen water  HW absorbed by the gastrointestinal tract plays an important role in oxidative-stress reduction, extracellular matrix reconstitution, and anti-inflammatory effects. Several experiments have supported our considerations as follows.

At first, it was demonstrated that molecular hydrogen gas (H2) has a beneficial influence on the gastrointestinal tract [29]. Kajiya et al. established a mouse model of human inflammatory bowel disease (IBD) by supplying to mice drinking water containing a) 5% dextran sodium sulfate (DSS), b) 5% DSS and molecular hydrogen H2, or c) molecular hydrogen H2 only ad libitum up to 7 days. They found that on day-7, DSS-induced pathogenic outcomes including elevated levels of IL-12, TNF-α and IL-1- β in colon lesion, etc. were significantly suppressed by addition of molecular hydrogen H2 to DSS solution. Thereby, it was concluded that molecular hydrogen H2 can make an anti-inflammatory influence on gastrointestinal tract in vivo[30].

Secondly, Nakashima-Kamimura et al. examined whether drinking water containing the saturated dissolved molecular hydrogen (HW: 0.8 mM molecular hydrogen H2 in water) is applicable by examining the effects of oxidative stress, mortality, and body-weight loss as well as serum creatinine, and blood urea nitrogen (BUN) levels. In in vivo experiments, their results showed that molecular hydrogen was detected in the blood when molecular hydrogen water  HW was placed via gavage at a dose of 15 mL/kg in the stomach of a rat, and molecular hydrogen water  HW is applicable to alleviate nephrotoxic side-effects induced by an anti-cancer drug, such as cisplatin [31].

Thirdly, as molecular hydrogen gas can act as a scavenger of ROS, Cardinal et al. tested the effect of treatment with molecular hydrogen water HW in a rat model of kidney transplantation. In consequence, treatment with molecular hydrogen water  HW improved allograft function, slowed the progression of chronic allograft nephropathy (CAN), reduced oxidant injury and inflammatory mediator production, and improved overall survival. Their conclusion was that molecular hydrogen water HW is an effective antioxidant and anti-inflammatory agent in vivo[32].

It was previously shown that some free radicals inhibit the wound healing process [33]. molecular hydrogen H2 is a colorless, odorless, tasteless gas, and it possesses some peroxidant reducibility. molecular hydrogen H2 is possible to easily pass through the small intestine villi into the human body inside and blood stream [15], because its molecular weight is the smallest of all molecule species, and it has gaseous and electrically neutral properties, as well as it shows a strong diffusion capacity. Moreover, molecular hydrogen H2 maybe has its special channels for transporting into intracellular space, such as the aquaporins (AQPs) for water, especially molecular hydrogen-holding water, and the Rhesus (Rh) proteins [34].

Thus, coupled with the body itself and the enterogenous-H2 molecular hydrogen presence, due to specified intestinal bacteria, molecular hydrogen water HW intake via TubeFeeding can play an important role on improving the formation of wound granulates on disintegrated necrosis loci, and the ability to have an anti-inflammatory effect through an ROS-reduction mechanism.

Additionally, it should be pointed out that apoptotic cells can stimulate proliferation, wound healing, and tissue regeneration [35]. We are focusing on “the apoptosis-induced compensatory proliferation” which occurs in PressureUlcers [36]. Generally, necrosis has an effect of the secondary lethal damage to the wound-surrounding cells of PressureUlcers through cell swelling and burst. By contrast, cell debris that is caused by cell shrinkage and fragmentation in apoptosis in which karyorrhexis (i.e. nuclear fragmentation) and pycnosis (i.e. nuclear condensation) are revealed as an early event, is subjected to endocytosis by both the migratory professional phagocytes (e.g.macrophages and Langerhans cells in the epidermis) and the surrounding non-professional phagocytes. So, it is thought that “the compensatory proliferation” is induced for the reason that cell debris is peaceably handled to restrain the surrounding cells within a minimal deteriorating impact. On this occasion, ROS may be able to be suppressed by the molecular hydrogen water to evoke an apoptosis more gently, and subsequently, apoptosis that is caused in wound-surrounding cells of PressureUlcers stimulates the compensatory proliferation to lead to an early healing. Indeed, Cai JM et al. reported that 2% molecular hydrogen gas inhalation administered to a neonatal hypoxia-ischemia rat model could reduce apoptosis [37].

When molecular Hydrogen Water-intake via TubeFeeding was combined with routine care treatments, the wound healing process can be markedly accelerated. Hence, the effective mechanism of molecular Hydrogen Water possesses at least two possible pathways, firstly is an antioxidant effect and secondly is an anti-inflammatory effect. Moreover, we thought that molecular hydrogen water HW may have additional effects, i.e. reconstruction of collagen and cytoprotection for other dermal as well epidermal cells. Therefore, we carried out an in vitro experiment on normal human dermal fibroblasts OUMS-36 and normal human epidermis-derived keratinocytes HaCaT to examine their interaction. Therefore, either dermal or epidermal cells were respectively cultured in molecular hydrogen water HW or reverse osmosis water  RW-prepared medium. Immunostain was used for observing type-I collagen reconstruction in OUMS-36 cells and showed the promotive effect. And cell viability of HaCaT cells was examined in terms of cell morphological observation and WST-1 assay, and their generated ROS, especially superoxide onion radials, was measured by NBT assay, respectively, all of which showed the cell-death-repressive and ROS-scavenging effects.

We have attempted to draw the illustrations for assuming a cure mechanism from stage III to wound healing during Pressure Ulcers (Figure 12).

Figure 12

Mechanism for wound healing of pressure ulcer by molecular hydrogen-dissolved water. We are predicting that ROS can lead to a pressure ulcer, and the causative process is shown by the left illustration. First of all, such diverse factors as bedridden syndrome, mechanical pressure and local ischemia produce ROS which causes necrosis and apoptosis in combination with other pathologic factors, potently resulting in wounds and tissue defects of pressure ulcer. On the other hand, the right illustration shows the healing mechanism. Oral intake of nano-bubble molecular hydrogen water via drinking or tube-feeding passes by the mouth or esophagus, and it is absorbed by the epithelial cells of the small intestines. It is possible that molecular hydrogen gas transpires in past from molecular hydrogen water  HW and inhaled by the lung. Then, the absorbed nano-bubble molecular hydrogen migrates to cutis tissue through blood circulation and scavenges ROS abundantly generated in Pressure Ulcers. Finally, this process results in collagen reconstruction of fibroblasts in the dermis and the proliferation of keratinocytes in the epidermis, and causes angiogenesis and remodeling for repairs in the defected tissue.

Consequently, our in vitro data demonstrated that intracellular ROS was diminished by molecular hydrogen water  HW, but not by reverse osmosis water RW, in UVA-irradiated OUMS-36 fibroblasts. Nuclear condensation and fragmentation were occurred for UVA-irradiated OUMS-36 cells in reverse osmosis waterRW, but scarcely occurred in molecular hydrogen water  HW as demonstrated by DAPI staining. Besides, in HaCaT cells, the mitochondrial dehydrogenase, especially succinate dehydrogenase activity was diminished in reverse osmosis water  RW-prepared culture medium with UVA-irradiation, but was retained in molecular hydrogen water HW-prepared culture medium as shown by NBT and WST-1 assay. Thus, UVA-induced ROS, especially singlet oxygen and superoxide onion radicals were suggested to be scavenged by molecular hydrogen and result in cytoprotection against ROS-induced mitochondrial dysfunction.

Similar results have been reported from previous research works on reconstruction of collagen in other dermal or epidermal cells by molecular hydrogen water HW [3839].

As a mechanism for using molecular hydrogen water  HW to treat PressureUlcers at aspect of dermal and epidermal cells, we consider that there are three pathways as follows:

(1) the promotion of the formation of dermis structure as well as reconstruction to type-I collagen,

(2) the prevention of the formation of wound granules on disintegrated necrosis loci, and

(3) the repair and restoration of scar tissues.

Healing effects for PressureUlcers patients through molecular hydrogen water  HW oral intake via TubeFeeding as shown by our present study have been scarcely found in the past. Our experience in this study added further evidences to a possible role in medical therapies for Pressure Ulcers. Additionally, as well known, there are different methods to manufacture the hydrogen water by diverse research groups, so there are also different water-parameters about molecular hydrogen water HW. In order to show our data obtained from measurements with the different dilution ratios, we had specially set up Figures 1 and 2, as well as Table 2 to present these achievements. How to manufacture molecular hydrogen water  HW and reverse osmosis water RW is an important and essential matter in the field of hydrogen water medicine.

But, this study has some limitations that should be considered when interpreting the results. Firstly the study design could not be carried out as the randomized control trail (RCT), because generally PU-cure clinical intervention test cannot be executed as RCT owing to other diverse factors such as various diseases concurrence and complication. Clinical situation did not allow us to get clinical data prior to one as we designed. Secondly we could not design the trial into comparing the results both molecular hydrogen water HW oral intake and external washing of injurious sites with molecular hydrogen water  HW, respectively. These deserve the next-step study.


molecular hydrogen water  HW intake via Tube Feeding was demonstrated, for severely hospitalized elderly patients with Pressure Ulcers, to execute wound size reduction and early recovery, both of which potently ensue from either type-I collagen construction in dermal fibroblasts or the promoted mitochondrial reducing ability and ROS repression in epidermal keratinocytes as shown by immunostain, NBT and WST-1 assays, respectively.

Molecular hydrogen water overview-definiton, benefits, research , studies  ,safety

molecular hydrogen water might sound new but it is not .

What is molecular hydrogen rich water ?molecular hydrogen  water or molecular hydrogen -rich water is water enriched or infused with dissolved  molecular hydrogen gas (molecular hydrogen  H2 NOT the H2 linked to O), also known as molecular hydrogen. 2 This means that hydrogen molecules or nano bubbles of molecular hydrogen are dissolved in the water, but do not actually bond with any of the H20 water molecules . another example are carbonated drinks  are enriched with CO2 (carbon dioxide gas) which gives these drinks their fizzy characteristic. 

So we have a gas made of 2 molecules of hydrogen in the water. Please note that alkaline ionize water also has more or less molecular hydrogen  H2 gas in it so Alkaline Ionized Water or Electrolysis Reduced Water is also Molecular Hydrogen Water

What is hydrogen gas?

Hydrogen gas is made up of two hydrogen atoms that are covalently bonded (2 atoms of hydrogen that share common electrons). This gas has a neutral charge and is the smallest and lightest gas in the universe. 6 These qualities make hydrogen gas extremely unique because it means molecular hydrogen  H2 can get anywhere it wants to in your body, including passing the blood-brain barrier, and into subcellular compartments such as the mitochondria of your cells. Molecular hydrogen is also known as a therapeutic medical gas with amazing medical potential in the scientific literature. 7

Is molecular hydrogen-rich water beneficial?

OF COURSE!!! Molecular hydrogen(water) has been demonstrated to be therapeutic in more than 600 scientific studies for more than 170 human disease models. 8 This means molecular hydrogen (water) has the therapeutic potential to help the vast majority of individuals today. Molecular hydrogen(water) has the potential to help the person dealing with seasonal allergies and to the person facing cancer. 9 Molecular hydrogen is one of the newest and simplest ways an individual can take preventative measures in their health.

Here are some examples of scientific studies refferring to molecular hydrogen) : In 1975, an impressive study demonstrated that hyperbaric molecular hydrogen therapy could be a possible treatment for cancer. In this study, the researchers showed that exposing mice with skin cancer (tumors) to 2.5 percent oxygen (O2) and 97.5 molecular hydrogen (H2) for two weeks produced a dramatic and significant regression of the mice tumors. Here is a quote from the study:

 “After a first 10-day period of exposure of the mice to the hydrogen-oxygen therapy it was found qualitatively (i) that the tumors had turned black, (ii) that some had dropped off, (iii) that some seemed to have shrunk at their base and to be in the process of being ‘pinched off,’ and (iv) that the mice appeared to suffer no deleterious consequences.” 5

In 2007 when a groundbreaking study demonstrated that molecular hydrogen is a selective antioxidant that neutralizes only the cytotoxic free radicals. The study was published in the prestigious Journal of Nature Medicine. 6 The study showed that molecular hydrogen neutralizes the hydroxyl radical (OH*), the most cytotoxic free radical in existence, one that the human body has no natural defenses against, and converts it into water.

Since 2007, medical research on molecular hydrogen has exploded proving this gas has remarkable medical potential.

Research studies and reviews about molecular hydrogen water

The evolution of molecular hydrogen (water): a noteworthy potential therapy with clinical significance

“Hydrogen has marked therapeutic potential to help with the top 8 fatality-causing diseases listed by the CDC.” 7

Molecular hydrogen: a therapeutic antioxidant and beyond

“Overall, the impact of molecular hydrogen in medicine is extraordinary. The non-toxic and rapid intracellular diffusion features of this biological gas ensure the feasibility and readiness for its clinical translation.” 8

Molecular hydrogen as a novel antioxidant: Overview of the advantages of hydrogen for medical applications

“Recent publications revealed that, in addition to the direct neutralization of highly reactive oxidants, molecular hydrogen  H2 indirectly reduces oxidative stress by regulating the expression of various genes. Moreover, by regulating gene expression, molecular hydrogen H2 functions as an anti-inflammatory, antiallergic, and antiapoptotic molecule, and stimulates energy metabolism. In addition to growing evidence obtained by model animal experiments, extensive clinical examinations were performed or are under way. Since most drugs act on their specific targets,molecular hydrogen H2 seems to differ from conventional pharmaceutical drugs. Owing to its great efficacy and lack of adverse effects, molecular hydrogen  H2 has potential for clinical applications for many diseases.” 9

Understanding the basic effects

Molecular hydrogen is a selective antioxidant 10

Molecular hydrogen appears to be a selective antioxidant. Molecular hydrogen appears to also reduce a powerful oxidant, Peroxynitrite (ONOO-). This would mean that Molecular Hydrogen has the potential to protect our DNA/RNA and proteins from damage (oxidative stress). Importantly, it does this while not perturbing cellular homeostasis;molecular hydrogen H2 does not neutralize beneficial free radicals (NO, H2O2, etc) necessary for the body to function properly.

Molecular hydrogen is a Nrf2 activator 11

Molecular hydrogen appears to stimulate the production of endogenous antioxidants via the Nrf2 Pathway, meaning it up-regulates the body’s own antioxidant system. This results in the production of more protective enzymes (antioxidants) such as glutathione, catalase, and superoxide dismutase. These antioxidants are powerful and aid in the reduction of excessive ROS and oxidative-stress within the body, which have been linked to nearly all human diseases.11.5

Molecular hydrogen is a signaling molecule/gene regulator 12

Molecular hydrogen appears to be a novel signaling molecule that participates in gene expression, cell modulation, and protein regulation. This means molecular hydrogen  H2 can alter cellular signaling pathways resulting in benefits far beyond its antioxidant function. Research has demonstrated that molecular hydrogen can regulate inflammatory cytokines, hormones, proteins, and much more.  Because of these properties, molecular hydrogen has the potential to give anti-inflammatory, anti-allergic, anti-cell death effects.

This is a short list of the potential therapeutic benefits for the human body that have been associated with molecular hydrogen  H2 research:

  • Selective antioxidant 10
  • Anti-Inflammatory Effects 11
  • Smallest, most bioavailable molecule 12

Who can drink molecular hydrogen water?

One of the best parts about molecular hydrogen water is that it has been shown to have a tremendous safety profile. This has been demonstrated in a few ways:

  • Out of 600-plus scientific studies, molecular hydrogen  H2 has shown no cytotoxic effects or cytotoxic by-products in the human body. 22
  • We have a basal level of molecular hydrogen  H2 in our blood stream at all times, around 1~5 micromolar or less. 23
  • Humans can produce up to 10 liters of molecular hydrogen  H2 a day with a good diet containing fruits, vegetables, and fiber-rich foods. This is due to the production of molecular hydrogen  H2 by our gut flora (gut bacteria). 24
  • Another reason we know molecular hydrogen H2 is safe is because it has been used to ameliorate decompression sickness in deep sea diving since 1945. 25 The molecular hydrogen H2 concentration has been as high 98.87 percent molecular hydrogen  H2 and 1.26 percent of O2, at 19.1 atm with minimal to no adverse or cytotoxic effects. 26 The United States military also has been using molecular hydrogen H2 for deep sea diving since the 60s. 27 Molecular hydrogen has been demonstrated to be extremely safe for the human body. 28


This information tells us that molecular hydrogen-rich water is safe for consumption in all age groups, from children to adults, as a preventive beverage that has the potential to reduce oxidative stress and so much more. Everyone, including children, is exposed to oxidative stress, which has been linked to the pathogenesis of nearly all disease conditions, including cancer. 29 Consuming water infused with molecular hydrogen is exactly what our society needs to aid in the battle against degenerative diseases.

Please note that most studies and research with molecular hydrogen gas were performed using molecular hydrogen rich water
