Hydrogen Water Guide

Hydrogen Water Guide: The Physics Behind the Marketing

This hydrogen water guide is written by a manufacturer, so we have an interest in what you conclude. These pages are written to survive that conflict: every figure is sourced, the limits are stated, and where a competing product wins a line, we say so.

Retention How Long Does Hydrogen Water Last? An open glass loses about half its dissolved hydrogen in two hours. The decay curve, why it happens, and a ten-minute test you can run yourself. 2 hours half-life in an open glass Concentration Hydrogen Water PPB: How Much Is Good? Why 1,600 ppb is a physical ceiling, what range research actually used, and why a ppb figure means nothing without a volume beside it. 1,600 ppb the saturation limit Compatibility Will a Hydrogen Water Cap Fit Your Bottle? Neck diameter, thread standard and neck height decide the fit - not whether the bottle is plastic, glass or steel. Three checks, one minute. 28 & 30 mm the two neck sizes that matter Comparison Hydrogen Tablets or a Bottle? Tablets reach a higher peak and travel without power. They also leave 80 mg of magnesium behind and never stop costing. Five honest lines. 80 mg magnesium per tablet Technology SPE vs PEM: The Simple Truth The two abbreviations name the same membrane - one by material, one by function. The comparison that actually matters is membrane or no membrane. 1 part two names, not two technologies Safety Is Hydrogen Water Safe? The Honest Truth Regulation and physics close the question for the hydrogen itself - a GRAS notice on file and a hard saturation ceiling. The real safety question is the cell design. GRN 520 FDA GRAS notice, "no questions" Evidence Do Hydrogen Water Bottles Work? 2-Part Answer One question, split honestly in two: the device - measurable in ppb with a meter or reagent drops - and the health evidence, promising but unfinished. 2 questions inside one answer

How to Use This Hydrogen Water Guide

Read this hydrogen water guide in any order, but there is a sequence that makes sense if the subject is new to you. Start with concentration, because almost every marketing claim in this category is a number. Then move to retention, because that number changes from the second it is measured. Compatibility and cell design come last, once you know what the figures mean.

What the numbers mean and where they stop being possible.
Why the same water reads differently ten minutes later.
Which bottle a cap actually fits, and why material is not the deciding factor.
How the two common routes to hydrogen water differ in what they leave behind.
What the abbreviations on the box describe, and what they hide.
Whether any of it is safe to drink every day, and where the real risk actually sits.
Whether the bottles work at all - the measurable half and the honest half.

Why This Hydrogen Water Guide Is Written This Way

Two rules hold across every page of this hydrogen water guide. First, no health claims. Molecular hydrogen is an active research area, and the honest summary is that studies exist and their limits are real - so we point to the literature itself rather than summarising it into a promise. The H2CAP PLUS is a consumer device, not a medical one.

Second, every figure carries its source. Concentration ceilings come from published Henry's law constants, bottle neck dimensions from the ISBT thread specifications, and trial doses from the registry entries themselves. Where a number is ours, we say how it was measured and publish the range rather than the best single reading.

This hydrogen water guide exists because the category is unusually noisy. Claims of 5,000 or 8,000 ppb circulate widely, and they are above what plain water holds at normal pressure. Rather than compete on bigger numbers, we give distributors and their customers the tools to check any device, including ours.

If you are evaluating us commercially, the same principle runs through our published test data and distributor documentation.
