Hydrogen is one of the most studied molecules in wellness.
With over 1,600+ peer-reviewed studies behind it, the ECHO Flask infuses your water with the most therapeutic dose — up to 8 ppm — verified by an independent lab.
Your body is fighting a battle you can't feel.
Every breath, every workout, every stressful day creates free radicals, unstable molecules that damage your cells from the inside out. Scientists call it oxidative stress. You feel it as fatigue, brain fog, slow recovery, and skin that's lost its glow.
Your body fights back with antioxidants — but most have a catch. Once they neutralize a free radical, they often turn into one themselves. Your body has to clean up after the cleanup.
In 2007, a landmark paper in Nature Medicine changed everything. Researchers proved that molecular hydrogen (H₂) is a selective antioxidant1 — small enough to reach your mitochondria, smart enough to neutralize only the harmful free radicals, and the only one that doesn't backfire on your body.
Since then, 1,600+ peer-reviewed studies have been published on hydrogen's effects across energy, inflammation, recovery, cognition, and skin.2
The catch? Hydrogen escapes any container in minutes. You can't bottle it. You can't store it. You have to make it fresh, every time.
That's what the ECHO Flask does.

Track every cycle, every sip, every goal — synced over Bluetooth.
Your wellness dollars work here.
Feel Better. Do Better.
Hydrogen water has been studied for its role in supporting how you think, move, recover, and age. Here's what 1,600+ studies are exploring.3
Gut Health Meets Immune Support
Your gut isn't just about digestion—it's a command center for immunity, energy, and mood. Research suggests hydrogen may support gut balance and reduce oxidative load, helping you feel more aligned from the inside out.
Gain Clarity & Focus
Hydrogen has been studied for its ability to help the body manage inflammation and oxidative stress in the brain—factors that influence focus, alertness, and mental endurance. Stay in the zone, longer.
Supercharge Your Metabolism
The smallest molecule in the universe, Hydrogen has been studied for its ability to support healthy energy metabolism and redox balance—two key drivers of stamina, metabolic efficiency, and humans who push harder and go further.
Upgrade Performance
Fuel your cells by supporting the systems behind endurance and recovery. By helping your body manage oxidative stress, it promotes better performance under pressure—whether you're crushing a workout, a deadline, or both.
Support Whole-Body Vitality
Resilience isn't optional—it's your edge. Hydrogen water can play a role in cellular signaling, stress recovery, and aging resilience. When your cells bounce back faster, so do you. Stay sharp, stay strong, and live fully charged.
Recover at the Cellular Level
Real recovery starts at the source. Hydrogen-rich water is being explored for its potential to support the body's natural repair processes. Whether you're training, fasting, or just demanding more from life, hydrogen is your quiet recovery ally.
We've perfected hydrogen.
Ten engineering decisions, one verified dose. Every part of the Flask was specified to deliver pure, lab-grade H₂ — and nothing else.
Backed by every kind of evidence.
There's hydrogen water. Then there's ECHO.
Most hydrogen bottles cost less for a reason. See what you actually get with the ECHO Flask versus what you don't get with everyone else.
Nine reasons most "hydrogen bottles" don't measure up. And one reason the Echo Flask has become the gold standard.
