Aoki 2012 Study.
Lactate observed to be decreasing.
2012, University of Tsukuba: placebo-controlled crossover study on 10 young football players, hydrogenated water around training for one week.
The authors observed less blood lactate during exercise and a smaller decrease in strength. A study result — not an individual promise.
Since then, Ostojic's work has explored endurance. The research continues. All studies on the science page.

3 research areas
Sport & H₂: what studies are looking at.
Recovery
A study (Aoki 2012, footballers) observed a decrease in blood lactate after exercise — a study result, not an individual promise.
Stamina
Hydrogenated water is being studied in endurance athletes (Ostojic, Medical Gas Research). This is ongoing work that we are following closely.
Oxidative stress
Post-exercise oxidative stress markers (MDA, 8-OHdG) are monitored in several studies on H₂, with hundreds of studies published since 2007.

Sportsmen's Questions
Before You Buy.
When to drink hydrogen water around a workout?
Dissolved hydrogen gradually dissipates: drink the freshly prepared water. The simplest schedule: one glass 30 minutes before the session, one glass within 15 minutes after. Step-by-step details are in the first use guide.
Does it replace my energy drink?
No. The HYDROGENYX Flask produces H₂-enriched water – without sugars or electrolytes. It can be integrated into your daily hydration routine; for long efforts, keep your usual carbohydrate drink.
What exactly does the research say about athletes?
Aoki 2012 observed a decrease in blood lactate in 10 soccer players; Ostojic's work explores endurance. These are study results — a field of research, not proof of individual effect. Sources and summaries are available on the science page.
What if I don't notice anything?
You have 60 days to test the Flask in your actual preparation, with a satisfaction or money-back guarantee. The only guaranteed figure is the concentration – verifiable by DPD test, covered for 5 years. Details on the guarantee page.
