What Vital Reaction's tablets are
Vital Reaction sells effervescent hydrogen tablets — an elemental magnesium formulation that reacts with water to release dissolved molecular hydrogen (H₂) gas. Drop a tablet into a glass of water, and it produces hydrogen-rich water in about a minute, no machine or power source needed.
What they claim
- Concentration: up to 8–10 ppm dissolved hydrogen per serving.
- Price: from $59.50 USD for a 60-tablet bottle.
- Recommended use: 1–2 tablets per day for general use, with higher doses suggested for athletes or specific health goals.
- Third-party testing: Vital Reaction states its products undergo third-party testing for purity and safety, though detailed certificates aren't always published alongside individual product claims.
What's worth knowing before you buy
The PPM number depends entirely on when it's measured. An 8–10 ppm figure is physically achievable — magnesium-tablet reactions can exceed water's normal atmospheric saturation point (1.6 mg/L) through supersaturation in the moments right after the reaction. But dissolved hydrogen is one of the most diffusive gases there is, and it starts escaping the instant the water is exposed to air. Published dissipation data puts the half-life of dissolved H₂ in an open 500 mL container at roughly two hours at room temperature — faster with any stirring or a wide opening. A concentration measured immediately after the tablet finishes reacting is a different number from what's actually in the glass by the time it's consumed. This isn't unique to Vital Reaction — it applies to every tablet brand — but it's rarely disclosed alongside the headline PPM figure.
It's a recurring cost, not a one-time purchase. At the recommended dose of roughly two tablets a day, a 60-tablet bottle lasts about a month — consistent with Vital Reaction's own customer feedback citing "a bottle a month" at around $60. That works out to approximately $720 USD (~$1,037 AUD) per year, indefinitely, for as long as you keep using them. There's no point at which the cost stops.
Your water source isn't controlled. Tablets work in whatever water is on hand — tap, filtered, bottled — which is part of their convenience. But it also means the mineral and contaminant profile of the water varies from use to use, and isn't something the product itself accounts for.
The legitimate research behind tablet-based delivery
The strongest published study behind high-concentration tablet dosing is LeBaron et al. (2020) — a randomized, double-blind, placebo-controlled trial in 60 adults with metabolic syndrome, using a magnesium-tablet hydrogen delivery system over 24 weeks. It's a real, peer-reviewed clinical trial, published in Diabetes, Metabolic Syndrome and Obesity, and it found favourable changes in cholesterol, glucose, HbA1c, and inflammatory markers versus placebo.
Two things worth knowing about it: the trial's dosing threshold was defined as more than 5.5 millimoles of H₂ per day (roughly 11 mg), delivered across multiple tablet doses — not a single 10 ppm glass — and the same research group has separately described their specific tablet formulation as producing around 8 ppm in 500 mL of water. That's a real, tested figure from a specific studied product, and it's in the same range Vital Reaction advertises. It doesn't independently verify Vital Reaction's own tablets specifically, but it does mean an 8–10 ppm claim from a tablet in this category isn't inherently implausible.

The alternative: a one-time purchase
If you're planning to use hydrogen water daily long-term, the cost comparison changes shape. Our W30-660 drinking machine is a one-time purchase at $2,695 USD / A$3,883.49 AUD, with no per-glass cost after that. Against roughly $720 USD / $1,037 AUD a year in tablet spend, the machine pays for itself in about 3.74 years — and every year after that is effectively free by comparison. It also runs on distilled water specifically, so the input is controlled and consistent rather than whatever happens to be on hand.
Neither format is wrong — tablets are genuinely better for travel, or for someone who only wants hydrogen water occasionally rather than daily. But for regular, ongoing use, the cost curve favours a machine well before most people expect it to.
