What is Hydrogen Water?
Definition and Basic Properties
Hydrogen water is essentially regular water into which hydrogen gas has been added. This modification is said to enhance the water’s anti-inflammatory and antioxidant properties, making it a popular choice for health-conscious individuals. It is often marketed for its potential benefits such as increased energy, slowing down the aging process, and aiding muscle recovery post-exercise 47. The basic composition of hydrogen water mirrors that of plain water, containing zero calories, carbohydrates, fats, and proteins. However, depending on the source and manufacturer, it may include trace amounts of vitamins and minerals like Vitamin A, Vitamin C, calcium carbonate, magnesium sulfate, potassium, and sodium sulfate 47.
How Hydrogen is Added to Water
To create hydrogen water, molecular hydrogen gas (H2) is dissolved into water under elevated pressure, creating a supersaturated solution. This process allows the tiny hydrogen molecules, which are the smallest existent gas particles, to penetrate the water and remain dissolved for an extended period 58. These molecules are not only small but also pervasive, capable of reaching every organ and cell in the body, including the brain.
This unique property facilitates the delivery of hydrogen’s health benefits such as antioxidant and anti-inflammatory effects, weight reduction, and anti-allergy actions, without any known side effects 6. Manufacturers offer hydrogen water in various forms, including pre-bottled options or tablets that can be dissolved in water, providing flexibility in how consumers choose to ingest it 47. Additionally, for those interested in a more hands-on approach, hydrogen water machines are available for home use, allowing individuals to infuse hydrogen gas into their water 9.
The production of hydrogen water adheres to high purity standards, with a hydrogen concentration of ≥99.99%, meeting the stringent requirements set by the U.S. FDA for food additives and the EU standards, ensuring its safety and efficacy for consumption [special user request].
Hydrogen Water as an Antioxidant
Mechanism of Antioxidant Activity
Hydrogen water exhibits its antioxidant properties primarily through the selective reduction of cytotoxic reactive oxygen species (ROS) in tissues. Studies have shown that hydrogen is effective against oxidative stress by reducing the oxidative damage that occurs between biological molecules and hydroxyl radicals 141011. This reduction in oxidized macromolecules leads to a decrease in cellular and mitochondrial injuries, enhancing overall cellular health 1. Notably, hydrogen-rich water can aid in the excretion of toxins from the liver to the bile and promote their fecal excretion, thereby supporting detoxification processes in the body 37.
Further, the consumption of hydrogen-rich water has been linked to significant increases in the levels of antioxidant enzymes such as superoxide dismutase (SOD), which plays a critical role in protecting cells from damage caused by superoxide, a by-product of oxygen metabolism 14. Additionally, hydrogen water has been shown to decrease levels of thiobarbituric acid reactive substances (TBARS) in urine, indicating a reduction in lipid peroxidation and thus lower oxidative stress 14.
Comparison with Other Antioxidants
When compared to other antioxidants, hydrogen water offers a unique advantage due to its ability to penetrate deeply into cells and tissues, including the brain, due to the small size of hydrogen molecules 58. This allows hydrogen to exert its antioxidant effects more efficiently throughout the body. Unlike some antioxidants that may exhibit pro-oxidant activity under certain conditions, hydrogen has no cytotoxicity even at higher concentrations, making it a safer option for long-term use 4.
In studies involving animal models, daily consumption of hydrogen-rich water has shown promising results in reducing conditions like atherosclerosis and alleviating cisplatin-induced nephrotoxicity, which are often associated with oxidative stress 1314. These studies highlight the potential of hydrogen water as a therapeutic antioxidant, not only in preventing but also in managing various oxidative stress-related conditions.
Moreover, the effectiveness of hydrogen water has been observed in human subjects, particularly in those with potential metabolic syndrome, where it helped reduce oxidative stress markers significantly 14. This positions hydrogen water as a potentially novel therapeutic and preventive strategy for managing and mitigating the effects of diseases characterized by high oxidative stress.
In conclusion, hydrogen water represents a potent and safe antioxidant source, with distinct advantages over traditional antioxidants. Its ability to provide wide-reaching antioxidant effects makes it a valuable addition to health regimens aimed at reducing oxidative stress and enhancing overall well-being.
Hydrogen Water and Athletic Performance
Improvement in Endurance
Hydrogen-rich water (HRW) has shown promising effects in boosting athletic performance, notably in endurance. Athletes drinking HRW have reported increased energy levels and improved endurance, which are crucial for prolonged physical activities 161718. This improvement is attributed to the antioxidant properties of hydrogen, which protect the body from oxidative stress, commonly experienced during intense physical exertion. Oxidative stress can lead to muscle fatigue and damage, but the antioxidants in HRW help mitigate these effects, thus enhancing endurance and performance 161718.
Recovery Benefits
One of the significant advantages of consuming hydrogen-rich water for athletes is the accelerated recovery rates post-exercise. Studies have indicated that HRW can effectively improve heart rate recovery after strenuous activities, such as dragon boat racing and high-intensity rowing tests 17. This rapid recovery is crucial for athletes who engage in repeated bouts of intense exercise, as it allows them to perform at high levels consistently without prolonged downtime between sessions.
Furthermore, HRW has been found to reduce physical fatigue by acting as an alkalizing agent, which helps decrease the pH levels in blood and muscles, thereby assisting in quicker recovery 1718. Athletes consuming HRW also experience reduced muscle soreness and a decrease in the fatigue index, which measures the decline in performance due to fatigue 18. This is particularly beneficial in sports that demand high-intensity and repeated performance, as it enables athletes to maintain optimal performance longer and recover more quickly from the exertions of their sport.
Anti-inflammatory Benefits of Hydrogen Water
Reducing Inflammation
Hydrogen-rich water has demonstrated significant anti-inflammatory properties, which are vital in the management and treatment of various chronic diseases. Research indicates that hydrogen acts on cells to exert antioxidant, anti-apoptotic, and cytoprotective effects, which are beneficial in reducing inflammation 14. A notable study involving female juvenile soccer players from Suzhou, China, highlighted the impact of consuming hydrogen-rich water over two months. The study observed a decrease in serum malondialdehyde levels, an indicator of oxidative stress, and changes in inflammatory markers such as interleukin-1, interleukin-6, and tumor necrosis factor-alpha (TNF-α), with interleukin-6 levels showing a significant increase from 8.74 ± 2.57 to 12.37 ± 3.2 ng/L in the hydrogen-rich water group 13.
Examples from Studies
Further supporting the anti-inflammatory benefits of hydrogen water, the study on female juvenile soccer players also reported an increase in total antioxidant capacity and a reduction in TNF-α levels, which decreased from 60.57 ± 10.09 to 132.24 ± 10.46 μM in the control group, compared to a more significant increase in the hydrogen-rich water group 13. These findings suggest that regular consumption of hydrogen-rich water could play a crucial role in modulating inflammation and enhancing the body’s antioxidant defenses.
Moreover, the consumption of hydrogen-rich water has been linked to improved outcomes in conditions associated with chronic inflammation. For instance, a study involving patients with liver cancer showed that drinking hydrogen-rich water during radiation therapy improved the quality of life and mitigated side effects such as fatigue and nausea, potentially due to its anti-inflammatory effects 27.
The integration of hydrogen-rich water into daily routines could therefore offer a therapeutic advantage for individuals suffering from inflammatory conditions, enhancing overall health and well-being.
Mental Health Benefits of Hydrogen Water
Mood Improvement
Hydrogen-rich water (HRW) has shown promising results in enhancing mood among various populations. Clinical studies have demonstrated that consuming 600ml of HRW can significantly improve mood by modulating the activity of the sympathetic nervous system 3132. This effect is attributed to HRW’s ability to rapidly permeate through cells and tissues, providing protection against oxidative stress, which is often linked to mood disorders 3132. Additionally, HRW has been found to reduce negative emotions, which are commonly associated with conditions like depression and anxiety, further supporting its role in mood enhancement 32.
Anxiety and Stress Reduction
The impact of HRW on anxiety and stress reduction is notable, particularly in its potential to intervene in stress-related disorders. Its antioxidant and anti-inflammatory properties help in mitigating the physiological responses to stress 31. For instance, HRW has been reported to improve the quality of life by reducing anxiety levels and decreasing the activity of the sympathetic nervous system at rest, which is often heightened during stress 3132.
Moreover, in a context where anticipatory anxiety from panic attacks prevails, HRW’s influence on the inflammatory response and normalization of the hypothalamic-pituitary-adrenal (HPA) axis can be particularly beneficial. This comprehensive intervention helps in restoring effective communication between distal organs, ultimately reducing symptoms associated with anxiety and panic 31.
Hydrogen Water and Oxidative Stress
Impact on Cellular Health
Hydrogen water’s influence on oxidative stress is profoundly beneficial, particularly at the cellular level. It effectively counters oxidative stress by reducing the damage inflicted between biological molecules and hydroxyl radicals 1. This reduction in oxidized macromolecules leads to decreased cellular and mitochondrial injuries, enhancing overall cellular health 1. Notably, hydrogen exhibits no cytotoxicity even at higher concentrations, ensuring its safety and efficacy in combating oxidative stress 4.
Oxidative stress, a significant contributor to lifestyle-related diseases, aging, and even cancer, is exacerbated by internally generated reactive oxygen species as we breathe and consume oxygen 4. Hydrogen water helps maintain a balance, ensuring that these species do not overwhelm the body’s antioxidant defenses, thus preventing cellular damage 4.
Evidence from Research
Research underscores hydrogen’s potential as a novel antioxidant due to its selective scavenging ability, particularly against potent oxidants like the hydroxyl radical. In ischemia/reperfusion injury models, hydrogen has been shown to prevent tissue damage and reduce infarct size 9. Additionally, in rat models of neurodegenerative disorders such as Parkinson’s and Alzheimer’s diseases, hydrogen administration improved memory function and slowed disease progression [10-12].
The tight linkage between oxidative stress and inflammation is also critical, as immune cells stimulated by ROS-damaged biomolecules promote an inflammatory response 34. Hydrogen water intervenes effectively by down-regulating the NF-κB signaling pathway, a key player in inflammation, and suppressing NF-κB-regulated genes in healthy mouse liver 4243. Furthermore, in animal inflammation models, hydrogen administration markedly reduced levels of pro-inflammatory cytokines such as IL-1, IL-6, and TNF-α 4243.
These findings highlight hydrogen water’s dual role in both mitigating oxidative stress and modulating inflammatory responses, making it a promising therapeutic agent for various oxidative stress-related conditions.
Safety and Potential Risks
Current Understanding of Safety
Hydrogen-rich water is generally considered safe for consumption. Experts have not identified any significant risks associated with drinking hydrogen water compared to regular water. However, the benefits of hydrogen water over staying hydrated with normal water are still under investigation 44. It is important to note that while hydrogen water has been found safe in various studies, some research has been supported by organizations with vested interests in hydrogen water products, which could introduce commercial biases 43. Additionally, the lack of placebo control groups in some studies makes it difficult to definitively attribute observed health benefits directly to hydrogen water 43.
Long-term Effects
The long-term effects of consuming hydrogen-rich water are not well-documented. Most studies to date have focused on short-term outcomes, and many of these studies have been conducted on animal models or with small human sample sizes, limiting their generalizability 4348. Furthermore, the variability in hydrogen concentration and hydrogenation methods across different studies makes it challenging to compare results and draw firm conclusions about long-term effects 4348. As such, more research with larger sample sizes and longer durations is needed to fully understand the potential long-term benefits or risks associated with hydrogen-rich water consumption.
In terms of potential risks, excessive consumption of water, including hydrogen water, can lead to hyponatremia. This condition occurs when the kidneys cannot excrete excess water, diluting the sodium in the bloodstream, which can be life-threatening. However, such instances are rare and usually only a concern for athletes engaged in intense exercise 44.
