New to H2Tab? Here&apos;s everything you need to know about what it is, what&apos;s in it, and what happens when you drop it in water.What is H2Tab?H2Tab is a molecular hydrogen tablet. Drop one into a glass of 12-16 oz of room-temperature still water, let it dissolve, and drink. Each tablet reacts with water to produce millions of tiny hydrogen nano-bubbles, releasing ultra-pure molecular hydrogen (H&#x2082;) at a concentration of up to 12 ppm&#x2014;one of the highest available in any tablet form.What&apos;s the active ingredient?The key ingredient is elemental magnesium. When the tablet contacts water, a natural reaction generates molecular hydrogen gas that dissolves directly into the water, leaving behind a small amount of bioavailable magnesium.What happens when you drink it?Molecular hydrogen is the smallest molecule in existence. Its small size allows it to absorb rapidly through the digestive tract into the bloodstream, then diffuse into cells, tissues, and mitochondria to support cellular function at a fundamental level.What does it support?<ul style="list-style-type: &apos;+ &apos;; margin: 0 0 16px 0; padding-left: 20px;"><li style="margin: 0px; font-size: 16px; font-family: Inter;">Oxidative stress: Helps neutralize the free radicals that build up from everyday stress, pollution, and exercise*</li><li style="margin: 0px; font-size: 16px; font-family: Inter;">Energy: Supports your body&#x2019;s natural energy processes at the cellular level*</li><li style="margin: 0px; font-size: 16px; font-family: Inter;">Recovery: Helps ease exercise-related stress on the body, supporting faster recovery*</li><li style="margin: 0px; font-size: 16px; font-family: Inter;">Gut health: Supports a healthy, balanced gut environment*</li><li style="margin: 0px; font-size: 16px; font-family: Inter;">Cognitive health: Supports brain health, since hydrogen is small enough to pass through the blood-brain barrier*</li></ul><div style="border: 1px solid #000; padding: 12px 14px; margin: 16px 0; font-size: 12px;">*These statements have not been evaluated by the Food and Drug Administration.

What is H2Tab, and how does it work?

There are several ways to get molecular hydrogen—here's how H2Tab compares to the most common alternatives. Hydrogen Concentration.

There are several ways to get molecular hydrogen&#x2014;here&apos;s how H2Tab compares to the most common alternatives.Hydrogen ConcentrationThis is the biggest difference&#x2014;each H2Tab tablet produces up to 12 ppm of dissolved molecular hydrogen. Most hydrogen water bottles produce 1-4 ppm per use, and that number decreases over time as the bottles age. Hydrogen machines vary widely but rarely sustain 12 ppm consistently.<ul style="list-style-type: &apos;+ &apos;; margin: 0 0 16px 0; padding-left: 20px;"><li style="margin: 0px; font-size: 16px; font-family: Inter;">H2Tab:&#xA0;Up to 12 ppm, verified by third-party lab testing on every batch</li><li style="margin: 0px; font-size: 16px; font-family: Inter;">Bottles:&#xA0;Typically 1-4 ppm, declining with use</li><li dir="ltr" style="text-decoration: none; font-family: Inter;" id="isPasted">Machines: Wide range, high upfront cost, requires ongoing maintenance</li></ul>Convenience + portabilityH2Tab requires no charging, no device, and no maintenance. Drop a tablet into a glass of 12-16 oz of room-temperature still water, wait 90-120 seconds, and drink. A tube of tablets fits in a pocket, gym bag, or carry-on. No cables, no equipment, no TSA concerns.CostH2Tab costs under $1 per tablet. Quality hydrogen water bottles start at $50&#x2013;$200+. Hydrogen machines range from $500 to several thousand dollars with ongoing filter and maintenance costs.BioavailabilityH2Tab uses a natural magnesium-acid reaction that releases hydrogen gas directly into the water at high concentration. The dissolved hydrogen is equally bioavailable to hydrogen produced by electrolysis devices.PurityH2Tab produces ultra-clean molecular hydrogen with no harmful by-products. Electrolysis devices can introduce trace ozone or chlorine gas as side products depending on the water source and device quality.<div style="border: 1px solid #000; padding: 12px 14px; margin: 16px 0; font-size: 12px;">Note:&#xA0;To match the hydrogen from one H2Tab tablet using a typical 4 ppm bottle, you would need to drink 5-6 full bottles in rapid succession.</div>

How is H2Tab different from bottles or machines?

H2Tab is rooted in real research and driven by real results. We’re committed to transparency, education, and putting science first.

Yes&#x2014;and in more depth than most supplement brands can claim. Here&apos;s what the research covers.Research on H2Tab&apos;s exact formulation*H2Tab&apos;s exact tablet formulation has been studied in 25+ peer-reviewed clinical trials&#x2014;making it one of the only hydrogen tablet products tested on its own formula, not just on molecular hydrogen in general. More studies are currently in progress.The broader body of hydrogen research*Beyond H2Tab&apos;s formulation, molecular hydrogen has been the subject of over 2,000 peer-reviewed publications and more than 170 clinical trials globally. This research spans athletic performance, cellular health, oxidative stress, gut function, cognitive support, and more.Third-party testingEvery batch of H2Tab is independently tested by H2 Analytics&#x2014;the leading molecular hydrogen testing laboratory&#x2014;to verify that each tablet consistently produces 12 ppm of dissolved hydrogen. You can see the H2 Analytics verification seal on the back of every H2Tab package.Who developed H2Tab&apos;s formula?H2Tab was developed in collaboration with Alex Tarnava, a leading researcher in molecular hydrogen science and the original architect of the open-cup hydrogen tablet technology. This is the same formulation used in the peer-reviewed clinical studies referenced above.Where can I read the research?<ul style="list-style-type: &apos;+ &apos;; margin: 0 0 16px 0; padding-left: 20px;"><li dir="ltr" style="text-decoration: none; font-family: Inter;" id="isPasted">H2Tab Science page:&#xA0;<a href="http://drinkh2tab.com/pages/science" style="text-decoration:none;">drinkh2tab.com/pages/science&#xA0;</a>&#xA0;</li><li dir="ltr" style="text-decoration: none; font-family: Inter;" id="isPasted">Peer-reviewed hydrogen research database:&#xA0;<a href="http://hydrogenclinicalresearch.com" style="text-decoration:none;">hydrogenclinicalresearch.com&#xA0;</a>&#xA0;</li></ul><div style="border: 1px solid #000; padding: 12px 14px; margin: 16px 0; font-size: 12px;">*Research cited refers to peer-reviewed studies on molecular hydrogen and H2Tab&apos;s specific formulation.&#xA0;These statements have not been evaluated by the Food and Drug Administration.
