The Basics

Benefits of Hydrogen Water

Supports Recovery

Molecular hydrogen is studied for selective antioxidant activity, linked to less oxidative stress after you push hard.

Supports Gut Balance

Early research explores hydrogen's role in your gut's microbial balance, an emerging area, not a settled one.

Supports Focus

Some studies link hydrogen's antioxidant activity to steadier clarity through your day.

Supports Rest

Early research associates hydrogen with calmer, more consistent sleep, so you wake up steadier.

In Simple Terms

What is Hydrogen Water?

TRUE Flask splashing into water

Hydrogen water is ordinary water with one thing added: molecular hydrogen gas, dissolved all the way through. No taste. No color. No sugar. Just water, doing one more thing for you.

  • The smallest molecule there is
  • Dissolves in without changing taste, color, or pH
  • Passes through cells the way plain water can't
  • First studied back in 2007
  • Already made in small amounts by your gut bacteria

By The Numbers

The research, at a glance.

  • 2007

    Hydrogen was first shown to neutralize harmful oxygen radicals, like hydroxyl radicals, while leaving beneficial ones untouched. It's the foundational mechanism behind hydrogen water research since.

    Nature Medicine, 2007

  • 25+

    Peer-reviewed human studies in a single 2024 systematic review

  • 12.6%

    In elite female athletes, hydrogen-rich water increased peak muscular torque after warm-up and lowered creatine kinase, a marker of muscle damage.

    Journal of Lifestyle Medicine, 2025 · n=22

  • Faster Sprints

    A review of exercise trials found hydrogen-rich water improved repeated-sprint times in footballers and power output in competitive rowers.

    Metabolites, 2024

  • 433

    Pooling 8 clinical trials, researchers found hydrogen-rich water modestly reduced liver enzyme levels compared to regular water.

    Gastroenterology and Hepatology from Bed to Bench, 2024 · n=433

  • n=256

    A pooled analysis of 7 randomized trials found hydrogen-rich water significantly lowered triglycerides, with modest drops in total and LDL cholesterol too.

    Pharmaceuticals, 2023 · n=256

  • 62.5%

    In adults with impaired fasting glucose, hydrogen-rich water reshaped gut bacteria and more than doubled fatty-liver remission versus plain water.

Questions

Good questions, plain answers.

How is TRUE Flask different from TRUE Pro?

TRUE Flask adds a second mode: tap the screen twice for 6,000 PPB, then run it again for up to 10,000 PPB, right from the on-bottle touchscreen. TRUE Pro runs a single 6,000 PPB cycle.

What does PPB mean?

Parts per billion, the standard unit for measuring dissolved molecular hydrogen concentration in water.

Isn't hydrogen already in water (H₂O)?

The hydrogen in H₂O is bonded to oxygen and isn't available to your body the same way. TRUE Flask adds separate, dissolved molecular hydrogen (H₂) gas to the water.

Is it safe to use every day?

Yes, it's designed to fit into your daily routine.

How do I switch between 6,000 and 10,000 PPB?

Tap the display twice for 6,000 PPB. Do the same again for up to 10,000 PPB. No app or account needed.
