Take H2TAB any time of day, but many athletes get the most benefit by drinking it before or immediately after a workout session. Consistency matters most — daily use is what drives cumulative cellular benefits.

One tablet per day is the baseline for most athletes. On high-output training days or back-to-back sessions, you can safely take 2–3 tablets to increase support when your body needs it most.

Molecular hydrogen is the smallest and lightest molecule in existence, which allows it to pass straight through cell membranes and into your mitochondria. Once inside, it selectively neutralizes the most harmful free radicals produced by intense exercise — reducing inflammation and oxidative damage without blunting your body's natural training adaptations.

Elemental magnesium is the key ingredient that generates the hydrogen gas. When the tablet hits water, a chemical reaction between the magnesium and a blend of natural fruit acids releases pure hydrogen nanobubbles into your drink. Magnesium also plays its own role in muscle function and recovery.

No. H2TAB is completely stimulant-free. The energy-supporting benefits come from reduced oxidative stress and improved cellular function — not from caffeine or any added stimulant.
