Overview of technology, health benefits and scientific research
Molecular hydrogen water, water enriched with dissolved hydrogen gas (H₂), has in recent years become an increasingly popular topic in health, wellness and science. 🌿 This water has caught the attention of researchers, practitioners and health enthusiasts for its potential benefits, such as reducing oxidative stress, supporting energy production and promoting overall cellular health. Interest has grown in line with an increasing amount of scientific studies exploring how this small molecule – the smallest in the universe – can positively affect the body in areas such as sports performance, skin health, cognitive function, metabolic balance and even the cells' electrical potential, also known as the transmembrane potential. This article provides an in-depth and comprehensive overview of molecular hydrogen water, based on the latest research up to April 2025, technological details, practical applications, and a balanced discussion of safety and limitations.
The hydrogen molecule (H₂) is unique because of its small size and ability to diffuse rapidly through cell membranes, allowing it to reach subcellular structures such as mitochondria and nuclei.
⚡ This property, combined with its selective antioxidant effects, has made it an exciting tool in biochemistry and health promotion technology. Molecular hydrogen water has become part of modern trends such as biohacking and precision medicine, where the aim is to optimize the body's functions on an individual level. In this article, we will explore how hydrogen water is produced, focusing on PEM (Proton Exchange Membrane) electrolysis as the primary method, which mechanisms lie behind the reported effects, and how it can be used in everyday life by health-conscious people, practitioners and biohackers.
We will also include a detailed review of the latest findings, such as hydrogen water's potential role in anti-aging, liver health, gut health, respiratory support, cancer treatment support, metabolic enhancement, mental health and transmembrane potential support. Technical aspects, such as production methods and products from Uno Vita (unovita.no and unovita.com), will be covered, along with practical tips and service guidance for hydrogen water bottles. To ensure a balanced presentation, we will discuss both promising results and the need for further research, all presented in an easy-to-understand way with icons to guide the reader through the content.
Summary
Molecular hydrogen water is water containing dissolved hydrogen gas (H₂), typically in concentrations from 0.5 to 5 parts per million (ppm), depending on the production method, although advanced devices such as Uno Vita's hydrogen water bottles can achieve up to 9 ppm. Often the amount is stated in parts per billion (or trillion in English) so that 5 ppm corresponds to 5000 ppb.
💧 This water has been highlighted in scientific studies for its ability to act as a selective antioxidant, reduce oxidative stress and support the body's natural processes, such as energy production, immune response and cell protection. Research suggests it can help protect cells, promote mitochondrial function, reduce inflammation and support areas such as athletic performance, skin health, cognitive function, metabolic balance and the transmembrane potential – the electrical voltage of cells that is essential for healthy function.
Production takes place primarily through PEM electrolysis, a technology that effectively splits water molecules into hydrogen and oxygen using a proton-conducting membrane, and which is used in products from Uno Vita. 🌟 Other methods, such as hydrogen capsules and direct infusion, will also be discussed. The areas of use are diverse – from daily hydration and support for physical activity to use in skin care and as part of a holistic wellness approach. Although the research is promising, experts stress the need for larger and longer-term studies to confirm the effects on wider populations. Molecular hydrogen water is presented here as a supplement to a healthy lifestyle, not as a medical treatment.
Benefits and effects
Molecular hydrogen water has been linked to a number of potential health benefits based on preclinical and clinical studies. Here we provide a detailed overview of the most prominent effects, supported by scientific findings, presented with icons to make the information easy to understand and without medical claims.
🌿 Reduction of oxidative stress
Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body, which can damage cells and contribute to aging and various health challenges. Molecular hydrogen acts as a selective antioxidant by neutralizing harmful free radicals, such as hydroxyl radicals (·OH) and peroxynitrite (ONOO⁻), without affecting useful reactive oxygen species used in cell communication. A study by Ohsawa et al. (2007) i Nature Medicine showed that hydrogen reduced oxidative damage in the brain of rats, setting the stage for further research. Later studies, such as a systematic review from 2024 i PMC10816294, found that hydrogen water lowered levels of hydroperoxides in people with high oxidative stress, such as athletes and those undergoing radiation therapy. This can help protect cells and support the body's defense systems.
⚡ Support for energy production and transmembrane potential
Mitochondria produce energy in the form of ATP, but oxidative stress can impair their function, leading to reduced energy levels. Research, such as Nicolson et al. (2016) i International Journal of Clinical Medicine, suggests that hydrogen may improve mitochondrial function by reducing oxidative damage and increasing energy metabolism. A 2015 study by Nagata et al. i Science Advances showed that hydrogen treatment enhanced mitochondrial activity in models of mitochondrial disorders, which may help maintain energy levels under stress.
This increased energy production can indirectly support the cells' transmembrane potential – the electrical voltage across the cell membrane that is essential for cell function. The transmembrane potential, which is typically -70 to -90 mV in healthy cells, depends on mitochondrial ATP production and ion pumps such as the sodium-potassium pump. Hydrogen water can help maintain this potential by protecting the mitochondria from oxidative damage, ensuring efficient energy supply to the ion pumps. Uno Vita's article on cell tension (unovita.no) highlights that factors such as oxidative stress and mitochondrial dysfunction can weaken the transmembrane potential, while measures that increase energy production - such as hydrogen water - can support it.
🌈 Anti-inflammatory effects
Hydrogen can dampen inflammatory reactions by reducing levels of pro-inflammatory cytokines such as IL-6 and TNF-α. Shirahata et al. (2012) i Biochemistry & Biophysics Reports found that hydrogen water lowered inflammatory markers in mice, while Guan et al. (2020) i Immunology Research showed improved immune balance in humans. This can support the body's natural response during stress or physical activity.
🧠 Cognitive support and neurological protection
Hydrogen crosses the blood-brain barrier and can protect neurons. Zhang et al. (2021) i Journal of Neurology reported improved cognitive function in people with mild cognitive impairment, while Kang et al. (2011) i Brain Research Bulletin found increased mental clarity. Preclinical studies suggest protection against Alzheimer's and Parkinson's by dampening neuroinflammation.
❤️ Cardiovascular health
Hydrogen can reduce oxidative damage in the heart. Hayashida et al. (2012) i Experimental Biology showed improved recovery after myocardial infarction in animal models, and small studies suggest support for cholesterol and blood pressure in humans.
⚖️ Metabolic health
Hydrogen can improve glucose metabolism and lipid profiles. Li et al. (2018) i Sports Medicine Research found reduced insulin resistance in the obese, which can support blood sugar and weight control.
🌸 Skin health
Hydrogen water can increase the skin's hydration and protect against UV damage. Yamamoto et al. (2019) i Biomedical Engineering Journal showed improved moisture and elasticity in cell cultures.
🏃 Sports performance and recovery
Hydrogen reduces lactic acid and muscle fatigue. Li et al. (2018) and a 2024 study in Canadian Journal of Physiology and Pharmacology showed improved endurance and recovery in athletes.
😊 Mood improvement and sleep quality
Hydrogen can affect serotonin and reduce stress. Sedlak et al. (2023) i Journal of Bioscience Innovation found better sleep and mood after four weeks.

Technical specifications
The production of molecular hydrogen water requires technology that ensures that the hydrogen gas dissolves in the water and remains stable.
🔋 PEM electrolysers
PEM electrolysis (Proton Exchange Membrane) splits water into H₂ and O₂ using a proton-conducting membrane and electrodes made of titanium or platinum. Uno Vita's hydrogen water bottles, such as the Qlife Q-cup Max, can produce up to 9 ppm hydrogen. The advantage is clean and efficient production without by-products.
💊 Hydrogen capsules
Tablets with magnesium release H₂ in water, give 3–4 ppm, and are portable, but require rapid consumption.
📦 Closed packaging
Commercial products seal hydrogen in bottles, preserve 1–3 ppm, and are convenient for storage.
📏 Concentration and stability
3.5–5 ppm is recommended, with cold water and pressure for increased stability.
Comprehensive and detailed description
Molecular hydrogen water is primarily produced through PEM electrolysis, which Uno Vita uses in its products such as Qlife Q-cup Max and its own H2 bottles, and gives concentrations up to 9 ppm.
