Key takeaways
- Hydrogen tablets generate H₂ through a magnesium–acid reaction that degrades in the water.
- Tablet manufacturers acknowledge the reactive material can leave trace contaminants, including heavy metals.
- SPE/PEM electrolysis produces hydrogen from purified water without dissolving or degrading anything.
- Hydrogen Machines systems are independently lab-verified at 99.991% hydrogen purity.
- Tablets are a hydration product; electrolysis is a clean hydrogen-generation technology.
How hydrogen tablets work
Hydrogen tablets generate hydrogen through a magnesium–acid reaction that must break down inside the water. As the reactive material degrades, tablet manufacturers acknowledge it can leave trace contaminants — including heavy metals — in the water. This is a category-wide characteristic of dissolving hydrogen tablets.
Electrolysis hydrogen is different
SPE/PEM membrane electrolysis produces hydrogen from purified water through a physical separation process. Nothing dissolves, nothing degrades, and purity can be independently verified — Hydrogen Machines systems are lab-verified at 99.991% hydrogen purity.
They serve different purposes
Tablets are a hydration product. Electrolysis is a clean hydrogen-generation technology. They are not interchangeable, and the choice between them depends on whether you want a portable drinking-water reaction or a repeatable, verified source of molecular hydrogen.
