What is Oxygen-Deprived Hydrogen Water?

Oxygen-Deprived Hydrogen Water is a term used to differentiate certain types of hydrogen water on the market. It includes hydrogen water where oxygen has been separated out, and water where the hydrogen concentration is significantly higher than the oxygen concentration.
Oxygen-Deprived Hydrogen Water is created by increasing the concentration of molecular hydrogen (H2) to an extremely high level in an oxygen-deficient environment. This means that in each serving, you will measure an exceptionally high hydrogen concentration, while the oxygen concentration is very low or has been largely removed.
This unique characteristic allows Oxygen-Deprived Hydrogen Water to offer superior therapeutic support. The high hydrogen concentration is not neutralized by oxygen within the same volume of water. The hydrogen can then easily permeate the body, seek out areas with a high concentration of free radicals, and provide its beneficial effects.
In contrast, hydrogen-rich water that still contains oxygen at a concentration equivalent to the hydrogen content is significantly less effective in supporting health conditions. In such water, only the “stray” hydrogen molecules that avoid neutralization by oxygen are able to neutralize free radicals and provide therapeutic benefits.

Therapeutic Potential of Oxygen-Deprived Hydrogen Water

The Mechanism of Hydrogen Action in an Oxygen-Deficient Environment
The molecular hydrogen in Oxygen-Deprived Hydrogen Water has the ability to neutralize free radicals, reduce oxidative stress, and protect cells from damage. The oxygen-deficient environment enhances this capability and simultaneously stimulates the body to produce its own natural antioxidant enzymes.
1. Hydrogen Water Produced via Electrolysis
This method uses an electric current to electrolyze water (H2O), separating it into hydrogen gas (H2) and oxygen gas (O2), which remain dissolved in the water.
- The Issue: Hydrogen and oxygen concentrations remain at nearly equal proportions within the same water volume. Over time, they easily react and recombine into original water (H2O). As a result, only “stray” hydrogen molecules that avoid recombination are able to provide therapeutic support.
2. Hydrogen Water Produced via Gas Infusion/Pressurization
This method involves bubbling or pressurizing pure hydrogen gas (H2) into water to increase the hydrogen concentration.
- The Benefit: Since pure hydrogen gas (not including O2) is infused into purified water, it can offer health support, and the operating cost is low.
- The Drawback: The gas pressurization method does not give the water a high alkaline pH, which reduces the body’s ability to absorb the hydrogen. Furthermore, the hydrogen easily escapes into the surrounding environment.

3. Hydrogen Water: Electrolyzed and Oxygen-Removed (Oxygen-Deprived)
This method uses an electric current many times stronger than other methods to electrolyze the water. The strong current separates the hydrogen and oxygen, after which a filtration system removes the majority of the oxygen. The resulting water is highly concentrated with pure hydrogen and contains very little oxygen.
- The Result: This water has an extremely high hydrogen concentration and is “oxygen-deprived.” It offers the best capability for reducing oxidative stress and is super-alkaline without chemical catalysts, making it safe for long-term use. This high alkalinity enhances the absorption of both the hydrogen and the water by the body.
- Conclusion: The therapeutic potential of hydrogen water is directly proportional to its level of oxygen-deprivation.
Recommendation: Compare the methods and choose one with a high, high-quality hydrogen index to ensure effective daily health support.
Health Conditions Letus SuperWater May Support
The Difference from Other Hydrogen Waters
While there are many types of hydrogen water on the market today, Oxygen-Deprived Hydrogen Water (Letus SuperWater) stands out due to its superior advantages:
- Higher Hydrogen Concentration: Letus SuperWater boasts a significantly higher concentration of molecular hydrogen (H2) compared to conventional hydrogen water.
- Oxygen-Deprived Environment: The oxygen-deficient environment allows the hydrogen to be more active and effective, delivering optimal health benefits.
- Carefully Tested Hydrogen Concentration and Alkalinity: Due to its rapid absorption capability, Letus SuperWater delivers results faster than other types of hydrogen water. This benefit is achieved by having both the high hydrogen concentration and the carefully controlled high alkaline pH.
Health Conditions Letus SuperWater May Support
The extremely high Hydrogen concentration in an “Oxygen-Deprived” environment can help support various health conditions. Specifically:
- Diabetes: May reduce blood sugar levels within 45 minutes and stabilize HbA1c levels after 1–3 months. It can also improve pancreatic function.
- Gout: May reduce uric acid levels within 45 minutes.
- Alcohol Detoxification: Helps reduce headaches when consumed simultaneously with alcohol.
- Dyslipidemia (High Blood Fats): Enhances the metabolism of beneficial fats and reduces the absorption of fats that contribute to high cholesterol.
- Cancer: Helps prevent cellular damage and supports the body during chemotherapy and radiation therapy.
- Parkinson’s and Alzheimer’s Disease: Protects nerve cells, increases Dopamine production, and supports nerve regeneration.
- Cardiovascular Disease: Improves vascular elasticity, prevents atherosclerosis (hardening of the arteries), and helps stabilize blood pressure.
- Stroke, Brain, and Spinal Cord Injury: Provides powerful antioxidant effects to reduce neurological damage.
- Liver and Kidney Health: Strengthens function and protects liver and kidney cells.
Scientific Research on the Efficacy of Hydrogen-Rich Water

Hydrogen’s Ability to Reduce Oxidative Stress
Hydrogen offers superior reduction of oxidative stress by selectively bonding with the Hydroxyl radical (OH−)—the most toxic free radical among Reactive Oxygen Species (ROS). This selective action allows Hydrogen to protect cells from the damage caused by this harmful free radical; however, Hydrogen does not react with other ROS that serve essential roles in the body. Hydrogen tends to seek out free radicals and reduce oxidative stress in various organs and tissues, including the liver, kidneys, brain, and lungs.
Therapeutic Potential for Diabetes
Kajiyama et al. (2008) conducted a randomized, double-blind, placebo-controlled crossover study on 30 patients with Type 2 Diabetes and 6 patients with Impaired Glucose Tolerance (IGT). The patients consumed 900 mL of H2 water or placebo water for 8 weeks, followed by a 12-week washout period.
Key Findings: Statistically significant improvements were observed in negatively charged low-density lipoprotein (LDL)-cholesterol, small dense LDL, and urinary 8-isoprostanes. Furthermore, in four of the six patients with Impaired Glucose Tolerance, H2 water improved their oral glucose tolerance test results back to normal levels.
Therapeutic Potential for Cardiovascular Health
Hydrogen gas inhalation is most often applied in the treatment of patients with Acute Myocardial Infarction (Heart Attack), as revascularization (reopening blocked coronary arteries related to the infarction) is a common surgical procedure.
Molecular Hydrogen can provide protection against myocardial damage caused by the development of atherosclerosis and other vascular diseases. Molecular Hydrogen helps limit the extent of the heart attack without altering blood glucose levels.
Support for Sports and Exercise Performance
Repeated sprint exercise can disrupt the redox balance in muscles, leading to systemic oxidative stress and muscle damage. Drinking Hydrogen water contributes to maintaining redox status during consecutive days of strenuous exercise and may help prevent the accumulation of muscle fatigue day after day.
