What is H2X?
H2X is a dietary supplement. One unflavored tablet dissolves in water and generates molecular hydrogen (H₂), a selective antioxidant.* Made in the USA in a GMP-certified facility.
What is molecular hydrogen?
H₂ is the smallest molecule. In this tablet, magnesium reacts with food acids in water and generates H₂ in the glass. Once it dissolves, drink. Don’t let the glass sit.
How do I use it?
Drop 1 tablet into 8–16 oz of water. Let dissolve. Drink immediately. Up to 3 times daily. Do not swallow dry. Open one sealed tablet at a time.
When should I take it?
Whenever it fits. Morning, before or after training, or in the afternoon. Consistency matters more than exact timing. Up to three times daily. Do not swallow dry.
Why unflavored?
No fruit flavor and no sweetener for taste. You may notice a mild metallic taste. That is the magnesium, not a flavoring.
Why is there magnesium in it?
Magnesium is the reactive mineral that generates H₂ when the tablet dissolves. Each serving provides 80 mg (19% DV). Magnesium also supports muscle function and energy metabolism.*
How long until I notice something?
Individual results vary. Some people notice the ritual in days; others notice less. We do not promise a timeline.
Is H2X safe?
Manufactured in a GMP-certified facility. Consult your healthcare provider before use, especially if you are pregnant, nursing, taking medication, or have a medical condition. Not intended for children.
What is the PPM?
We do not print a dissolved-H₂ PPM on the carton. Formulation-level gas chromatography of this tablet class has been reported; that is not a lot-specific number for the units in our warehouse. Once it dissolves, drink. H₂ leaves if the glass sits.
Why does H2X dissolve so much faster?
H₂ starts the second moisture touches the mineral. In PVC-aluminum or a shared bottle, that can be inside the pack. Alu-alu is the gold standard for moisture protection, so H2X stays dry until you drop it. In the same temperature water it then dissolves about twice as fast as a typical PVC-aluminum tablet. We have side-by-side film. Once dissolved, drink.
Why not a bottle of tablets?
A plastic or glass bottle puts every tablet in the same air. Closed, a small HDPE packer still takes on about 0.8 mg of water per day at 40 °C / 75% RH; PET is worse (~9.9 mg/day). Open it and humidity hits all of them. H2X pops one sealed tablet. Alu-alu film of this class is ≤ 0.005 g/m²·day versus ~3–5 for 250 µm PVC.
How is this different from a hydrogen water bottle?
That’s a different product. Bottled hydrogen water is made earlier, then the gas can leave. H2X is a dry tablet. Hydrogen is generated when you drop it. Sealed until water.
How is this different from flavored tablets?
One SKU. Unflavored. 80 mg magnesium declared. Made in the USA for a San Diego company.
What does it cost?
$44.99 for one 30-count. Same price per box up to 23. 24 or more is wholesale. US shipping is included in the price. Monthly is $35.99 a box by bank debit, every 30 days, until you cancel. Cancel anytime at /cancel or by emailing info@h2xusa.com. Shop buttons open the product page for the $44.99 box. Add to cart there, then checkout on Wix.
Do you offer a guarantee?
Yes. US shipping is included in the price. 30-day money-back on unopened product for the amount you paid. Opened dietary supplements are not returnable unless defective.
Shipping?
We ship within the United States. Orders typically leave within one business day. Transit is usually 2–7 business days. You get a tracking number.
What is alu-alu?
Foil on both sides of each tablet, cold-formed. It is the moisture barrier. Typical hydrogen tablets use a PVC pocket with a foil lid, or a shared bottle. Alu-alu is why the tablet stays dry until you drop it.
Why is the tablet a little gray?
That is the mineral. It is unflavored. No dye to make it look like candy.
Does it have a flavor? Calories?
Unflavored. No fruit flavor. A mild metallic taste is normal; that is the magnesium. Other ingredients on the panel are dextrose and food acids (malic, tartaric, adipic). Calories are listed as 0.
Can I drop it in coffee, juice, or sparkling water?
Use still water, 8–16 oz. That is the intended use. Other drinks change the dissolve and the amount of hydrogen that stays in the glass.
Do I need a special hydrogen bottle?
No. A regular glass is the point. Drop, dissolve, drink. Do not let it sit.
Can I take it every day?
Suggested use is up to three tablets daily. Do not swallow dry. Do not exceed the recommended daily dose. If you are pregnant, nursing, on medication, or have a medical condition, ask your healthcare professional first.
How should I store it?
Keep the box dry and at room temperature. Leave each tablet in its foil until you use it. Do not dump the count into a pill box or bottle.
Can I travel with it?
Yes. Keep tablets in the sealed foil until you need one. Same as other dietary supplements in a carry-on. A glass of water on the other side is the whole ritual.
Do you ship outside the United States?
Not yet. U.S. addresses only. Questions: info@h2xusa.com.
Do you sell wholesale?
Yes. Write us from the Wholesale page.
Can I split or crush a tablet?
No. Use one whole tablet in water. Crushing it in air starts the reaction before you drink.
