Hydrogen Machines vs. HEALR H2: Electrolysis vs. Tablet-Based Hydrogen Water

How Each Technology Works

HEALR H2 uses a dissolving tablet. According to HEALR's own product information, each tablet contains elemental magnesium and a blend of acids; when dropped in water, a redox reaction between the magnesium, the acids, and the water releases molecular hydrogen gas directly into the glass.

Hydrogen Machines systems use PEM/SPE membrane electrolysis: a proton exchange membrane physically separates hydrogen and oxygen from purified water, producing hydrogen gas without dissolving any reactive material into the water at all.

Both approaches genuinely deliver molecular hydrogen. The difference that matters is what else ends up in the glass along with it.

The Trade-Off Worth Knowing About

Tablet-based hydrogen relies on a reactive metal compound breaking down in your water. HEALR is candid about the category-wide risk this creates. In HEALR's own words, describing tablet-based hydrogen products generally:

"...may in fact contaminate your water with heavy metals as the working components degrade." — HEALR, drinkhealr.com

That's not a claim we're making about HEALR — it's HEALR's own published caution about how effervescent hydrogen tablets work as a category. It's a fair and useful thing to know before choosing a delivery method, and it reflects the underlying chemistry: a tablet has to leave something behind as it dissolves, by design.

Electrolysis has a different profile entirely. Because hydrogen and oxygen are separated through a membrane rather than generated by a dissolving reactive tablet, there's no reactive material degrading in your water and nothing engineered to leave residue behind. Hydrogen Machines' hydrogen purity is independently lab-verified at 99.991% — a figure you can request documentation for, not a marketing claim alone.

Where Tablets Have a Real Advantage

In fairness: tablets are genuinely more portable than any electrolysis device. If you want hydrogen water while travelling with zero equipment, that convenience is real, and it's the legitimate reason this product category exists. The trade-off is between that portability and the purity/residue profile above — not a case where one option is simply better in every respect.

Frequently Asked Questions

Is HEALR H2 made the same way as electrolysis-based hydrogen water?
No. HEALR H2 uses a dissolving magnesium-and-acid tablet to generate hydrogen gas directly in the glass. Hydrogen Machines systems use PEM/SPE membrane electrolysis, which physically separates hydrogen from purified water rather than dissolving a reactive tablet into it.

Are hydrogen water tablets safe?
Tablet manufacturers, including HEALR, acknowledge that as the reactive tablet material degrades in water, it can introduce trace contaminants — including heavy metals — into the water. This is a disclosed, category-wide characteristic of tablet-based products, not unique to any single brand.

Which produces higher-purity hydrogen water: tablets or electrolysis?
Electrolysis systems separate hydrogen through a physical membrane, so purity can be independently lab-verified — Hydrogen Machines' systems are verified at 99.991% purity. Tablet-based hydrogen is generated through a chemical reaction in the glass itself, alongside the tablet's other dissolving ingredients.

Is hydrogen water tablet convenience worth the trade-off?
That depends on your priorities. Tablets are more portable for travel. Electrolysis systems avoid introducing any dissolving reactive material into your water. Neither is universally "better" — they suit different use cases.
