25 real questions about hydrogen tablets, answered

Aloha Hydrogen Tabs are effervescent molecular hydrogen (H₂) tablets. Drop one tablet into 12–16 oz of water, let it dissolve, and drink the resulting hydrogen-rich water. Made in the USA, ships to the USA and Canada.

Drop one tablet into 12–16 oz of room-temperature water. Allow it to fully dissolve for about two minutes. Drink promptly for the freshest hydrogen-rich water.

About two minutes in room-temperature water. Cold water slows the reaction; warm water speeds it up.

Multiple tablets in one glass may saturate the water quickly, but excess H₂ escapes as gas. For best results use one tablet per 12–16 oz.

No. Filtered tap water or bottled drinking water works. Very cold or very warm water changes the dissolve time.

You will see fine effervescence and a faint cloud of magnesium hydroxide byproduct that clears as the tablet fully dissolves. Rinse your glass promptly for the cleanest look.

Adults typically use 1–3 tablets per day, each dissolved in 12–16 oz of water. Follow all package directions. Consult your healthcare provider if you take other supplements or medications.

H₂ is the smallest and lightest molecule in the universe — two hydrogen atoms bonded together. It is a neutral, non-polar gas that diffuses across cell membranes, and it has been studied as a selective antioxidant since the 2007 Ohsawa et al. paper in Nature Medicine.

Yes. Effervescent hydrogen tablets use elemental magnesium plus organic acids (typically malic and tartaric) to release molecular hydrogen gas. Trace magnesium remains in the finished water. Count it toward your daily magnesium goal.

Peer-reviewed literature considers approximately 1.5 ppm and above "therapeutically relevant." Most quality tablets claim 8–12 ppm at peak in the stated water volume; real-world results typically settle in the 6–10 ppm range with normal handling.

Finished-product testing is part of Aloha's quality program. Our full certificate of analysis (CoA), including tested PPM under stated conditions, will be published on the Science page as batch data becomes available.

No. Aloha Hydrogen Tabs is a dietary supplement, not a drug. It is not intended to diagnose, treat, cure, or prevent any disease. Statements have not been evaluated by the U.S. Food and Drug Administration.

Molecular hydrogen has a strong safety profile in the published human literature. If you have kidney disease, are pregnant, breastfeeding, or on prescription medication, consult your healthcare provider before starting.

Some users report mild digestive changes when starting — this is usually related to the small magnesium load. Reduce to one tablet per day if this occurs.

Aloha Hydrogen Tabs are formulated for adults 18+. Ask your pediatrician before giving any dietary supplement to a child.

Because tablets contain magnesium and produce hydrogen gas, they may interact with certain medications. Please ask your prescriber first if you take blood-pressure, kidney, or thyroid medications.

Each package is stamped with a best-by date. Unopened, tablets typically remain effective for 18–24 months when stored properly.

Ask for a certificate of analysis (CoA), require the tested PPM to be stated with water volume, temperature, and measurement method, verify GMP manufacturing, and prefer brands with a satisfaction guarantee and no subscription lock-in.

Machines can produce continuous hydrogen water at home, but they cost $200–$800, need maintenance, and are not portable. Tablets are single-serve, travel-friendly, and typically deliver 8–12 ppm at a fraction of the cost.

The 3 leading US brands share a similar effervescent format and $29.95 / 30-count price point. Aloha's differentiators are: made in the USA, ships to both USA and Canada, no subscription lock-in, and a transparent testing-first approach to any PPM claim.
