Twist-to-Mix

Fresh beats premixed.

Most functional drinks mix everything at the factory and let it sit for months. Our twist-to-mix cap, an instant mixing cap with a sealed powder chamber, keeps the actives dry. You twist, it drops, you drink it fresh.

  1. 01Twist the cap.
  2. 02Shake for three seconds.
  3. 03Sip. That's the ritual.

The tech

Small molecules. Spread evenly.

MCD stands for Micro Controllable Dispersion. It's our proprietary process for spreading functional ingredients through liquid at the micron level, so the first sip and the last sip match.

Our hydrogen water takes the same idea down to nano scale: hydrogen infused as ultrafine bubbles under one micron, sealed in aluminum.

Hydrogen water, explained

The smallest antioxidant there is.

Hydrogen water is pure water with molecular hydrogen (H2) dissolved into it. No taste, no smell, no fizz. H2 is the smallest molecule in the universe, small enough to spread easily through water and through the body.

What makes it interesting is how it works as an antioxidant. In research, hydrogen reacts with the most aggressive free radicals, like the hydroxyl radical, while leaving alone the useful ones your body relies on for signaling. Scientists call it a selective antioxidant.

  • Antioxidant supportHelps your body handle everyday oxidative stress.*
  • Training and recoveryStudied in athletes before and after exercise.*
  • Clean hydrationZero sugar, zero calories, nothing else added.
What the research says
A selective antioxidant

A landmark 2007 study in Nature Medicine found that molecular hydrogen selectively neutralized the hydroxyl radical, one of the most reactive free radicals, while leaving helpful signaling molecules intact.

Ohsawa et al., Nature Medicine, 2007
After exercise

In a 2012 pilot study with elite soccer players, drinking hydrogen-rich water before a workout was linked to lower blood lactate during and after exercise.

Aoki et al., Medical Gas Research, 2012

Hundreds of studies have explored molecular hydrogen since 2007. Many human studies are still small, so we share the research as it stands instead of promising results.*

Our story

It started with the smallest molecule on Earth.

Picture Tokyo, 2 a.m., a tiny lab above a ramen shop. The Japanese scientist Dr. Jeffery Sonoyama had a very personal reason to be there: his young daughter was living with eczema, and he wanted to find a gentle, everyday ritual that could support her and help her feel good in her own skin. That search led him to hydrogen water, and to a mission that was simple and slightly unhinged: make the smallest molecule on Earth actually stay in a drink.

Hundreds of prototypes later (RIP to every bottle that went flat before breakfast), the team cracked it. Seal the hydrogen in. Keep the actives dry in the cap until you twist. Mix it fresh, every single time.

What started at a kitchen table spread to friends, then friends of friends. In 2021 the idea landed in Australia and became Boundless: twist-to-mix shots, hydrogen water and coconut water, made to lab-bench standards. Clean inputs, real doses, nothing you don't need. Next stop, the US.

EffectiveBuilt on research, not hype.
SafeNo unnecessary ingredients.
AccessibleEasy to fit into a real day.

The honest FAQ

Fair questions. Straight answers.

What is a longevity shot?

Our Longevity Shot is a 25 mL twist-to-mix drink. Ergothioneine, PQQ, astaxanthin, ceramides and sialic acid stay dry in the cap until one twist drops them into a hydrogen water base. Golden apple flavor, sweetened with allulose, zero sugar.

Is the Sleep Shot a sleep drink?

Yes. It's a zero-sugar evening drink with GABA, 50 mg of magnesium, jujuba, ergothioneine and PQQ, mixed fresh with one twist. Lavender flavor, made for your wind-down.

Does your coconut water have electrolytes?

Yes. It's cold-filled and never from concentrate, so it keeps coconut's naturally occurring electrolytes like potassium. Choose it pure with hydrogen, or as one of four twist-to-mix functional flavors.

Is hydrogen water an antioxidant?

Molecular hydrogen is studied as a selective antioxidant. A 2007 study in Nature Medicine found it neutralized the hydroxyl radical, one of the most reactive free radicals, and small human studies since have looked at antioxidant enzymes and exercise recovery. The research is still growing, and we share it as it stands.

Isn't hydrogen water just hype?

Fair question. The research is still young, and we won't promise miracles. What we do promise: real molecular hydrogen sealed in, zero sugar, and a drink that's easy to have every day.

What does it taste like?

Light and bright. Allulose keeps it sweet with zero sugar and none of the stevia aftertaste.

Why ergothioneine?

It's a nutrient your body can't make on its own. You get it from foods like mushrooms. Every Longevity Shot carries it, alongside PQQ and astaxanthin, and the dose goes on the pack.

What is an instant mixing cap?

It's a bottle cap with a sealed chamber that keeps a dry powder apart from the liquid until you twist. Ours is the twist-to-mix cap: turn it clockwise, the powder drops in, shake, sip.

What is nanobubble hydrogen water?

Water carrying molecular hydrogen, with part of the gas held as ultrafine bubbles under one micron, too small to see. Boundless hydrogen water comes in three hydrogen levels, 0.8, 1.2 and 1.6 ppm, sealed in aluminum cans.

Why twist instead of premixed?

Some ingredients are happier dry. Keeping them in the cap until you twist means they meet the water fresh.
