Understanding Hydrogen Water
Water molecules are composed of two hydrogen atoms bonded to one oxygen atom (H2O). Hydrogenated water, also known as hydrogen-rich or hydrogen-infused water, is created by dissolving extra molecular hydrogen gas (H2) into regular water. Because this added hydrogen is unbonded, some proponents claim it is more accessible to the body, where it can act as a selective antioxidant by neutralizing harmful free radicals. Molecular hydrogen is tasteless, odorless, and non-toxic. Consumers can obtain it in three primary forms: pre-bottled, dissolvable tablets, and at-home generators.
Bottled Hydrogenated Water Brands
For convenience, several companies offer pre-packaged hydrogen water. These products are sealed in materials like aluminum cans or special pouches to prevent the tiny hydrogen gas molecules from escaping, similar to how carbonated drinks are packaged.
- HFactor: A prominent brand offering hydrogen-infused water in portable hydro-packs. The company emphasizes using pure water and packaging that prevents hydrogen leakage.
- Dr. Perricone Hydrogen Water: Sourced from artesian water in Virginia and infused with hydrogen. It is packaged in aluminum cans and marketed for benefits like energy and cellular health.
- ELEVATE SuperWater: This brand advertises a high hydrogen concentration (up to 3-5 ppm) and a low Oxidation Reduction Potential (ORP), claiming superior antioxidant properties.
- Susosu Hydrogen Water: An infused water from South Korea using all-natural mineral water. It is sold in portable spouted pouches.
Creating Hydrogen Water at Home
For consumers seeking a fresher product or a higher concentration, at-home methods offer flexibility and potential long-term cost savings. The two main DIY methods are tablets and generators.
- Hydrogen Water Tablets: This method involves dropping specially formulated mineral tablets into water, which creates a chemical reaction that releases molecular hydrogen. While highly portable, some brands may contain magnesium hydroxide, which can have a laxative effect for some users. Brands include Hydrotab and tablets from Researched Nutritionals.
- Hydrogen Water Generators: These devices, often in the form of water bottles or larger countertop units, use electrolysis to produce hydrogen gas. The best generators use Solid Polymer Electrolysis (SPE) and Proton Exchange Membrane (PEM) technology to ensure pure hydrogen infusion without unwanted byproducts like chlorine or ozone. Popular brands for these generators include:
- Echo: Offers portable options like the Echo Go+ and Echo Flask.
- Nixcer: Provides a range of bottles like the HydroPeak and HydroGo, focusing on high hydrogen levels and user-friendly features.
- Piurify: Known for its reliable generation and extended hydrogen retention in the bottle.
- Hydroh: A popular generator bottle that uses SPE and PEM technology.
Comparison of Hydrogen Water Options
| Feature | Pre-Bottled Water | Hydrogen Tablets | Home Generators/Bottles |
|---|---|---|---|
| Convenience | Highest. Grab and go. | High. Tablets are portable. | Moderate. Requires power and time. |
| H2 Concentration | Can vary widely. Hydrogen can dissipate after opening. | Generally consistent. | Can be very high and user-controlled (ppm/ppb). |
| Purity | Depends on the manufacturer. | Depends on tablet ingredients (some contain magnesium). | High with advanced SPE/PEM technology. Avoids byproducts. |
| Cost | Highest per unit. | Lower initial cost, but ongoing tablet purchases add up. | High initial investment, but lower long-term cost per use. |
| Environmental Impact | Creates waste from packaging (cans, pouches). | Creates waste from individual wrappers. | Lower long-term waste with a reusable bottle. |
| Shelf-Life | Must be consumed before hydrogen dissipates from container over time. | Long shelf life for tablets. | Freshly made and consumed immediately for best results. |
Is Hydrogen Water Backed by Science?
While hydrogen water has gained significant market traction, it is important to approach the claims with a critical eye. Multiple studies, including reviews on PubMed Central, acknowledge the therapeutic potential of molecular hydrogen, particularly its antioxidant and anti-inflammatory effects. Early research in areas like athletic performance, metabolic syndrome, and anti-aging show promise, but many studies are small or in their preliminary stages.
Health experts, including those from WebMD and Healthline, note that while hydrogen water is generally considered safe and non-toxic (the FDA lists hydrogen gas as "Generally Recognized as Safe" up to a certain volume), extensive, long-term research is still lacking. The specific benefits can also depend on factors like the hydrogen concentration, which can vary significantly between products. It is best to consider hydrogen water a supplement to a healthy lifestyle, not a replacement for a balanced diet and regular exercise. For further reading on the importance of basic hydration, see Mayo Clinic's guide to drinking water.
Conclusion
No single "best" brand of hydrogenated water exists, as the ideal choice depends on your needs and budget. The market offers a wide variety of ways to get hydrogenated water, from convenient pre-packaged bottles by brands like HFactor and Dr. Perricone to more cost-effective, high-concentration DIY options. Hydrogen water tablets offer portability, while at-home generators using advanced SPE/PEM technology provide a consistent and potentially higher-quality product. While early research on the benefits of molecular hydrogen is encouraging, consumers should be mindful that more large-scale scientific validation is still needed. Ultimately, the right choice depends on balancing convenience, cost, and the desired hydrogen concentration for your wellness goals.
How to Choose the Right Product
If you decide to try hydrogen water, consider these factors before purchasing:
- Method of Generation: Decide if you prefer the convenience of pre-bottled, the portability of tablets, or the consistency and control of a generator.
- Technology: For generators, look for those with SPE and PEM technology to ensure purity and avoid byproducts.
- Concentration (ppm): Look for products that clearly state the hydrogen concentration in parts per million (ppm) or parts per billion (ppb). Levels between 1.5 and 4.0 ppm are often cited as a therapeutic range.
- Material and Portability: Look for durable, food-grade materials like borosilicate glass or Tritan plastic, especially for portable generator bottles.
- Third-Party Testing: Choose brands that provide third-party verification of their hydrogen concentration and technology to ensure product quality and safety.
Is Hydrogen Right for You?
Before adding any new health trend to your routine, it's always wise to research and assess your own needs. While hydrogen water appears to be a safe hydration supplement, its specific benefits require more clinical proof. Whether you choose a brand of bottled water or a device to make your own, the most important part of any hydration strategy remains consistent, adequate intake of clean water. For those seeking a potential edge in athletic recovery or cellular health, exploring hydrogen water options may be worth the investment, keeping realistic expectations about the current state of scientific evidence.
Which Water for Your Generator?
If using a home generator, the type of water matters. Many manufacturers recommend purified, distilled, or low-mineral spring water. Avoid carbonated water, which can damage the device and interfere with the process, and some alkaline waters with high mineral content that might affect the electrolysis. Always follow the manufacturer's specific instructions for your product.
