What is the difference between AWAKE and hydrogen tablets?
AWAKE is ready-to-drink hydrogen water with over 11 PPM of molecular hydrogen, bottled under pressure in a BPA-free can or special glass bottle. Hydrogen tablets do not contain finished hydrogen. They only generate it through a chemical reaction of elemental magnesium with the water in the glass – inevitably leaving chemical residues behind.
The decisive difference lies in three factors: purity (AWAKE without by-products), concentration (AWAKE delivers stable >11 PPM), and comfort (AWAKE ready to drink instantly, no sediment).
Why molecular hydrogen?
Molecular hydrogen (H₂) is the smallest and lightest molecule in the universe. Since a groundbreaking study in 2007, H₂ has evolved from a chemical side topic to an exciting subject of biomedical research. There are now more than 3,000 publications worldwide investigating H₂ in preclinical and clinical contexts.
High Diffusion Capability
Due to its extremely small size, H₂ passively penetrates biological membranes, cell membranes, mitochondria, and potentially even the blood-brain barrier – without transporters, without detours.
Selective Antioxidative Properties
H₂ is described in the literature as a selective antioxidant. It preferentially reacts with particularly aggressive reactive oxygen species (ROS) such as the hydroxyl radical, but does not interfere with physiologically necessary signal ROS.
Metabolic Neutrality
The only noteworthy reaction product is water. No bioactive by-products are formed – a decisive advantage over other antioxidant concepts.
Hydrogen Tablets: What really happens in your glass?
Anyone who buys hydrogen tablets is not buying ready-made hydrogen water. They are buying a chemical reaction starter. The main ingredient of most H₂ effervescent tablets is elemental magnesium – a metal normally used in industry for alloys. When the tablet is dropped into water, the magnesium reacts with the water. Hydrogen gas (H₂) is produced – but not alone.
Mg + 2 H₂O → Mg(OH)₂ + H₂. The by-product of this reaction is magnesium hydroxide (Mg(OH)₂). It is a strong base, does not dissolve completely, and remains as a whitish turbidity or sediment in the glass.
The chemical limits of hydrogen tablets
The by-product magnesium hydroxide is not a harmless residue – it is a strong base that measurably raises the pH of the water. This effect is chemically unavoidable: it inevitably arises from the reaction that also produces the hydrogen. Taste, pH, and tolerability of the water are thus altered – regardless of manufacturer or tablet quality.
Anyone who wants to take molecular hydrogen in a targeted and controlled manner therefore reaches a fundamental chemical limit with tablets: hydrogen and magnesium hydroxide cannot be separated from each other in this reaction.
Magnesium hydroxide remains after the reaction as a whitish turbidity or sediment in the glass – a strong base that changes the pH.
Advertised peak PPM refers to the glass immediately after dissolution. By the time you drink, most of the hydrogen has escaped.
Through enormous partial pressure and nanobubble technology, AWAKE delivers a stable >11 PPM – without chemical residues in the water.
What makes hydrogen tablets problematic in practice
Sounds like a quick solution on the go – but anyone who looks closer recognizes the hurdles. These three weaknesses should be known to users before reaching for H₂ effervescent tablets.
Gas loss: Advertised PPM values are often not achievable
Hydrogen is the most volatile gas of all. When the tablet dissolves in an open glass, a large portion of the resulting H₂ immediately escapes into the ambient air – before you even lift the glass to your mouth. Manufacturers advertise 5–10 PPM, but at the moment of drinking, the actual concentration is significantly lower. What is on the package does not reach the body.
Magnesium hydroxide: The residue you see (and taste)
The chemical reaction is unavoidable: where magnesium meets water, magnesium hydroxide is formed. This by-product remains in the drinking water, changes the pH, makes it cloudy, and leaves a metallic or chalky aftertaste. In sensitive people, regular consumption can irritate the stomach or have a laxative effect.
Waiting time & effort: No real comfort on the go
Tablets take 1–5 minutes to dissolve. You need a glass, clean water, and time. During sports, while traveling, or in the office, this is often impractical. And as soon as the glass is left open, the hydrogen escapes – waiting only prolongs the problem.
AWAKE: Nanobubbles + Pressure Filling – Hydrogen Without Compromises
To avoid the chemical by-products and gas loss of tablets, AWAKE relies on a fundamentally different process: no chemistry kit in the glass, but industrially controlled physics in the can.
Pressure filling: Over 11 PPM through enormous partial pressure
Under extreme pressure, pure hydrogen gas is pressed directly into the water. No chemical reaction takes place. The result: over 11 PPM of molecular hydrogen – a multiple of what is realistically achievable with tablets in an open glass.
Nanobubble technology: Stably dissolved, not degassed
Nanobubble technology creates tiny gas bubbles that massively increase the surface area of hydrogen in the water. This keeps H₂ stably bound in solution instead of immediately degassing again – the key to stable concentration until opening.
Diffusion-tight packaging: BPA-free can or glass bottle
Hydrogen diffuses through plastic faster than any other gas. PET bottles are therefore completely unsuitable. AWAKE is exclusively bottled in 100% BPA-free aluminum cans or glass bottles – diffusion-tight, with overpressure that maintains the PPM concentration until opening.
100% purity: Only water and H₂ – nothing else
No magnesium hydroxide. No sediment. No metallic taste. AWAKE contains exclusively purest water and pure molecular hydrogen – in the can rounded off with 100% natural lemon-lime aroma.

Frequently asked questions about hydrogen tablets in comparison
Everything you need to know about hydrogen tablets, H₂ effervescent tablets, and ready-to-drink hydrogen water – answered compactly.
Hydrogen tablets do not contain finished hydrogen – they only generate it through a chemical reaction of magnesium with water. This produces magnesium hydroxide as a by-product, which remains in the water. Ready-to-drink hydrogen water like AWAKE is produced physically: pure H₂ gas is pressed into the water under pressure. No chemistry, no residues.
They are generally not considered acutely harmful. However, the resulting by-product magnesium hydroxide is a strong base. In sensitive people or with regular consumption, it can irritate the stomach or have a laxative effect. It also noticeably changes the taste of the water.
Manufacturers often advertise 5–10 PPM. Since the tablet dissolves in an open glass, the volatile H₂ gas quickly escapes into the ambient air. At the moment of drinking, the real concentration is usually only 4–7 PPM. AWAKE maintains a constant >11 PPM thanks to pressure filling – until the can is opened.
AWAKE is completely ready-to-drink. You don't need a glass, water, waiting time, or sediment. Simply open the can or bottle and drink the full concentration immediately. Ideal for sports, travel, and everyday life.
PPM stands for 'Parts per Million' and indicates how much molecular hydrogen (H₂) is dissolved in the water. The higher the PPM value, the more H₂ is contained in the water. What matters is not only the initial value but also the stability: how much PPM is still present when you actually drink?
Yes. Since the study by Ohsawa et al. (2007) in Nature Medicine, over 3,000 publications on molecular hydrogen have been published worldwide. The research is promising but not yet complete. H₂ is not a pharmaceutical drug and no healing claims can be derived.
This is due to the magnesium hydroxide formed during the chemical reaction. It is a strong base that changes the pH of the water and leaves a characteristic metallic or chalky aftertaste.
This is an individual decision. To note: with daily consumption, the magnesium hydroxide residues accumulate. Anyone who wants to drink H₂ water daily is better served with a residue-free, ready-to-drink solution like AWAKE.
Hydrogen diffuses through plastic faster than any other gas. PET bottles are therefore unsuitable. AWAKE is exclusively bottled in diffusion-tight aluminum cans (BPA-free) or glass bottles that preserve the overpressure and thus the PPM concentration until opening.
AWAKE is available directly through the online shop – as a can with natural lemon-lime aroma or as a special glass bottle with pure H₂ water. We deliver within Germany.
