The Science Behind Cancro
Not lighter in calories. Lighter at the atomic level — with less of a heavy hydrogen isotope that may affect how your cells produce energy.

Discovered 1931
Harold Urey won the Nobel Prize for discovering deuterium — a hydrogen atom carrying an extra neutron. Same chemistry, but twice the atomic mass.
The Kinetic Isotope Effect
This isn't theory — it's established chemistry. Bonds involving deuterium break up to 10× slower than hydrogen bonds.
Why Reduction Helps
Your mitochondria produce energy using ATP synthase — a molecular motor powered by hydrogen ions. When heavier deuterium ions enter the flow, they can disrupt the motor's rotation.
Lower deuterium means fewer disruptions. Research suggests this may support more efficient cellular energy production and reduced oxidative stress.

The Research
Since the 1990s, researchers in Hungary, Russia, Japan, and the US have studied deuterium-depleted water. Cell studies show reduced proliferation in cancer lines.
Human trials are limited but promising — one Phase II study showed delayed progression in prostate cancer patients.

The Process
You can't filter out deuterium — the molecules are chemically identical. Separation requires exploiting tiny differences in boiling point and vapor pressure.
Water evaporates at low pressure. Light water evaporates slightly faster.
Hundreds of cycles progressively concentrate lighter molecules.
Isotope ratio mass spectrometry confirms exact ppm in every batch.
A New Grade of Water
Most water contains around 150 parts per million (ppm) of deuterium. We lower that concentration to help your body's metabolic engine run cleaner.
