Hydrogen water has many potential health benefits, such as antioxidant properties, better hydration, and possible therapeutic effects. However, one common concern among consumers is how long hydrogen water retains its beneficial hydrogen content. The shelf life of hydrogen water depends on various factors, including packaging, storage conditions, and the method of hydrogen infusion. This guide from Optimal Health explores how long hydrogen water lasts, what affects its longevity, and how to maximise its benefits.
What is Hydrogen Water?
Hydrogen water, also known as hydrogen-rich water or hydrogenated water, is regular water that has molecular hydrogen gas (H2) added to it. This simple addition has sparked the interest of researchers and health professionals. The duration of hydrogen water's effectiveness is important for assessing its practical application. Upon exposure to air, hydrogen starts to dissipate rapidly, with the majority escaping within 1-2 hours in an open container. However, when properly stored in an airtight, filled container without headspace, hydrogen water can retain its concentration for up to 1-2 weeks.
Health Benefits of Hydrogen Water
Scientists believe that drinking hydrogen water may offer certain benefits, but many remain uncertain whether these advantages surpass those of regular water. Maintaining proper hydration, in general, is essential for overall health.
Many medical experts highlight the need for further research to confirm or uncover any potential benefits of hydrogen water. However, based on early studies, the following are some possible advantages:
1. Antioxidant and Anti-Aging Effects
Hydrogen acts as a selective antioxidant, meaning it targets harmful free radicals without disrupting beneficial ones. Free radicals contribute to oxidative stress, which is linked to ageing and various chronic diseases. By neutralising these damaging molecules, hydrogen water may help slow the ageing process, protect cells from damage, and support overall health.
A recent study found that consuming hydrogen-rich water (hydrogen water ) had positive effects on several ageing-related factors in healthy older adults, including an increase in the length of protective DNA structures (telomeres) and a potential improvement in DNA methylation.
2. Anti-Inflammatory Properties
Chronic inflammation is a major factor in many health conditions, including arthritis, autoimmune disorders, and metabolic diseases. Some studies suggest that hydrogen water may help reduce inflammation by lowering oxidative stress and modulating the body's inflammatory response, offering relief for individuals with chronic inflammatory conditions.
3. Better Athletic Performance and Recovery
Exercise-induced oxidative stress can lead to muscle fatigue, soreness, and delayed recovery. Hydrogen water may help counteract these effects by reducing lactic acid buildup, minimising muscle damage, and speeding up recovery time. Some athletes and fitness enthusiasts use hydrogen water as a natural way to improve endurance and performance while promoting faster post-workout recovery.
For instance, a pilot study involving elite athletes found that consuming hydrogen water before exercise prevented the typical increase in blood lactate levels during heavy exercise. Additionally, peak torque, indicative of muscle fatigue, decreased less in the hydrogen water group compared to the placebo group, suggesting a protective effect against exercise-induced muscle fatigue.
4. Improved Metabolic Health
Early research suggests that hydrogen water may have a role in improving metabolic function, particularly in regulating blood sugar levels and enhancing insulin sensitivity. These effects could be beneficial for individuals with diabetes, prediabetes, or metabolic syndrome by helping to stabilise glucose levels and support overall metabolic health.
A randomised, placebo-controlled trial with 60 people with metabolic syndrome tested the effects of high-concentration hydrogen-rich water (hydrogen water ) over 24 weeks. The study found that hydrogen water helped lower blood cholesterol and glucose levels, reduced haemoglobin A1c (a marker of long-term blood sugar), and improved inflammation and antioxidant markers. Hydrogen water also slightly reduced body mass index (BMI) and waist-to-hip ratio compared to the placebo.
5. Cardiovascular Benefits
Oxidative stress is a key contributor to heart disease, high blood pressure, and other cardiovascular conditions. Some studies indicate that hydrogen water may help improve blood vessel function, reduce cholesterol levels, and lower inflammation, which could contribute to better heart health and reduce the risk of cardiovascular diseases.
A systematic review and meta-analysis examined the impact of hydrogen-rich water on blood lipid profiles across various clinical populations. The analysis indicated that hydrogen-rich water consumption positively influenced lipid profiles, which are critical markers for cardiovascular health.
6. Supports Brain Health and Cognitive Function
The brain is highly susceptible to oxidative stress, which has been linked to cognitive decline, neurodegenerative diseases like Alzheimer’s and Parkinson’s, and mental fatigue. Hydrogen water’s antioxidant properties may help protect brain cells, reduce inflammation, and enhance cognitive function, potentially lowering the risk of neurological disorders.
A 2008 study found that stress increased brain oxidative stress in mice, leading to memory and learning problems. However, drinking hydrogen water reduced these stress markers, prevented cognitive decline, and helped protect brain cell growth in the hippocampus, supporting brain function under stress.
7. Promotes Skin Health and Hydration
Oxidative stress and inflammation contribute to skin ageing, dryness, and conditions like eczema or acne. Hydrogen water may support skin health by improving hydration, reducing wrinkles, and promoting skin cell regeneration, leading to a more youthful and healthy complexion.
How Long Does Hydrogen Water Retain Its Hydrogen Content?
The longevity of hydrogen in water varies depending on several factors, including the container type, storage conditions, and exposure to external elements. Below are key considerations affecting hydrogen water stability:
1. Container Type
The type of container used to store hydrogen water plays an important role in its retention.
-
Glass Bottles: Porous and allows hydrogen to escape quickly. Hydrogen water stored in a glass bottle may lose most hydrogen within a few hours.
-
Plastic Bottles: Some plastics, especially PET (polyethylene terephthalate), allow hydrogen to slowly diffuse out, reducing its effectiveness within 24 hours.
-
Aluminum Cans & Foil Packaging: These are better at retaining hydrogen content, keeping it stable for days or even weeks.
-
Vacuum-Sealed Containers: These are the most effective at preserving hydrogen levels for extended periods, potentially up to several weeks.
2. Temperature and Storage Conditions
-
Refrigeration: Keeping hydrogen water cool helps slow down the escape of hydrogen molecules.
-
Room Temperature: At room temperature, hydrogen can dissipate more quickly, typically within a few hours to a day.
-
Exposure to Light: UV rays can accelerate the loss of hydrogen, so storing the water in a dark, cool place is ideal.
3. Method of Hydrogen Infusion
-
Dissolvable Hydrogen Tablets: Typically, these maintain high hydrogen levels for a few hours after being mixed with water.
-
Hydrogen-Rich Machines: Water produced by electrolysis can retain its hydrogen content for up to a day, depending on the storage method.
-
Pre-Packaged Hydrogen Water: Commercially bottled hydrogen water with specialised packaging can last several weeks to months before opening.
How Long Does Hydrogen Water Last in Different Storage Conditions?
1. Freshly Made Hydrogen Water
If you generate hydrogen water using an electrolysis machine or hydrogen tablet, it is best consumed immediately. Within a few hours, the hydrogen content drops unless stored in an optimal container. The loss of hydrogen in freshly made water can begin as soon as 15-30 minutes if left exposed to air. Using hydrogen-retaining bottles can extend the retention period to a few hours, but ideally, hydrogen water should be consumed within the first 1-2 hours for effectiveness.
2. Store-bought hydrogen Water in Bottles
Commercially available hydrogen water in PET or glass bottles typically lasts between 6 to 24 hours before most of the hydrogen dissipates. Some manufacturers use advanced sealing techniques or add stabilising elements to prolong hydrogen retention, but in general, regular plastic or glass containers allow hydrogen to escape quickly. If purchasing bottled hydrogen water, always check for airtight sealing and consider consuming it as soon as possible after opening.
3. Hydrogen Water in Aluminum Pouches
These pouches are designed to retain hydrogen for extended periods, sometimes up to 6 months, provided they remain sealed. The effectiveness of aluminium pouches comes from their ability to block gas permeability, preventing hydrogen from escaping. However, once the pouch is opened, hydrogen will begin to dissipate rapidly, usually within a few hours. If you need hydrogen water to last longer, choosing unopened aluminium pouches is the best option.
4. Refrigerated vs. Room Temperature Storage
Refrigeration can slightly slow the escape of hydrogen, but it does not completely prevent it. Keeping hydrogen water in a cool, dark place can extend its usability. Hydrogen gas remains more stable at lower temperatures, so if you must store hydrogen water, placing it in the refrigerator may help retain some of its potency for a longer period. However, refrigeration does not significantly extend the lifespan of hydrogen in open containers, so even chilled hydrogen water should still be consumed relatively quickly.
Best Practices for Preserving Hydrogen Water
To guarantee you get the most out of hydrogen water, follow these storage tips:
-
Use Aluminum Pouches: Whenever possible, purchase hydrogen water in aluminium pouches to extend shelf life. These pouches are specifically designed to prevent hydrogen from escaping, making them the most effective storage option.
-
Drink Immediately: If you use a hydrogen water generator, consume the water as soon as possible. Freshly made hydrogen water begins to lose its hydrogen content quickly, so drinking it immediately for maximum benefit.
-
Keep Containers Sealed: Avoid frequent opening and closing of bottles. Every time the container is opened, hydrogen escapes rapidly. If you need to store hydrogen water, choose a container that remains sealed until consumption.
-
Store in a Cool Place: Heat accelerates hydrogen loss, so refrigeration can help. However, do not freeze hydrogen water, as extreme temperatures may alter its properties and cause structural changes in the container.
-
Use Specialised Bottles: Some manufacturers produce hydrogen-retaining bottles that minimise gas loss. These bottles are designed with materials that reduce permeability and can help keep hydrogen in the water for longer periods.
-
Avoid Agitation: Shaking or excessive movement of the container can cause hydrogen to escape more quickly. Store hydrogen water in a stable position to reduce unnecessary gas loss.
-
Check Expiration Dates: If purchasing hydrogen water from a store, pay attention to expiration dates. While aluminium pouches can extend shelf life, hydrogen concentration may still diminish over time.
Hydrogen water is known for its antioxidant and health-supporting properties. However, its benefits are directly tied to how well it is stored and how quickly it is consumed. Since hydrogen gas is highly volatile and escapes easily, proper storage is important to maintain its potency.
For the best results, freshly made hydrogen water should be consumed immediately, while store-bought hydrogen water in bottles should be used within 24 hours. If long-term storage is necessary, aluminium pouches offer the best retention, keeping hydrogen stable for several months when sealed. Refrigeration can help slow hydrogen loss, but it does not completely prevent dissipation.
By following the best storage practices—choosing the right containers, reducing exposure to air, and keeping hydrogen water in a cool, dark place—you can ensure that you get the most benefits from this unique beverage. Whether you are looking for better hydration, antioxidant support, or overall wellness, consuming hydrogen water at peak freshness will yield the best results.
