What are mitochondria and why are they so important?
Understand your cellular energy. If your 37 trillion cellular batteries aren’t optimised, you aren’t either.
Mitochondria lose efficiency and resilience before you feel it — affecting recovery, muscle performance, and metabolic flexibility.
Aging isn’t only “making fewer mitochondria.” It’s also clearing damaged ones less efficiently over time. Muscle is mitochondria-dense tissue, so supporting renewal matters for strength and endurance.
The best changes are often subtle and compounding — not dramatic and temporary. Broken mitochondria block fat loss.

The DDW Solution
Drinking Litewater and maintaining a deuterium-depleted state (under 125 ppm) serves as an upstream solution to reduce excessive mitochondrial reactive oxygen species (ROS).
What is ROS?
Reactive Oxygen Species (ROS) are unstable oxygen molecules produced during energy production. In excess, they create “internal rust” that damages cells, proteins, and DNA, contributing to fatigue and aging.
Reduce ROS, Reclaim Energy
Deuterium depletion is the key to cellular efficiency.
An Exclusive Litewater Offer
Taking care of your mitochondria is the real fountain of youth.
Track mitochondrial performance with the world's first and only at-home Mitochondria Efficiency Test.
What you will discover about your Mitochondrial energy and performance
mescreen™ is an at-home test that assesses multiple dimensions of mitochondrial performance — both at rest and under a controlled “stress” condition — from a simple blood spot.
* This is designed for insight and optimization — not as a diagnosis tool.

"I wanted a deeper look into how my system manages stress."
“I’ve been drinking Litewater for 5+ years… I feel steady energy and recover quickly — but I wanted a deeper look.”
“mescreen™ gave me actionable insight into how my mitochondria perform at rest and under stress.”
“One interesting finding: despite demanding a lot from my system, my oxidative stress markers were unusually low — a signal I’m managing stress well. I attribute a lot of my results to the way I live, and my commitment to deuterium depletion.”
