Litewater

The lightest natural water on Earth is Antarctic snow. 89 ppm.

Seawater sits at 155.76 ppm deuterium — a figure with a name, VSMOW, Vienna Standard Mean Ocean Water, the reference point isotope labs calibrate against. There's a second standard for the other end of the scale. SLAP: Standard Light Antarctic Precipitation. 89 ppm. About 43% below the ocean.

The mechanism is distillation, and it runs on mass. A water molecule carrying deuterium is heavier than one that isn't. When an air mass rises and cools, the heavy molecules condense and fall out first, and the vapour left behind is a little lighter than it was. Do that once and the change is negligible. Do it across an ocean, up a continent, into the coldest air on the planet, over and over for hundreds of thousands of years, and you get Antarctic snow.

That's the lowest level found anywhere in nature. It's also sitting under a research station at the bottom of the world, in a place with no permanent population, where the only people who ever touch it arrive by government expedition. The lightest natural water on Earth is effectively inaccessible to everyone alive.

Same physics, run deliberately, goes further. Fractional distillation columns separate the heavy molecules from the light ones by the identical mass difference — just controlled, repeated and measured instead of left to the sky. The atmosphere had no reason to keep going. A column does.

Litewater is 10 PPM. 9x lighter than the lightest water in nature, and it ships to your door.

What is deuterium?

Deuterium is a heavy isotope of hydrogen. One proton, one neutron, one electron — roughly double the mass of the hydrogen your cells are built to run on. Chemists call regular hydrogen protium. Deuterium is the heavy version, and it’s in every water source on earth. Tap, spring, glacier, artesian, bottled. All of it.

Why deuterium matters biologically: your enzymes evolved on protium. That includes the enzymes that replicate and repair your DNA, and the ATP synthase motors inside your mitochondria that produce cellular energy.

The kinetic isotope effect explains what goes wrong. It’s foundational physical chemistry, not a Litewater theory — a carbon-deuterium bond breaks several times slower than a carbon-hydrogen bond. Heavier atom, slower reaction. This is taught in isotope science and has been established for decades.

So when deuterium sits in a position built for hydrogen, the reaction that follows doesn’t run the way it should.

In 1975, T.R. Griffiths proposed a mechanism by which deuterium occupies protium binding positions in DNA repair enzymes, contributing to replication errors over time. In 2007, biochemist Abdullah Olgun modeled how deuterium interferes with ATP synthase — the molecular motor at the center of your energy production.

What is deuterium depleted water? DDW is water with most of its natural deuterium removed, lowering the ppm well below what any tap, spring, or filtered water carries. No home filter does this. Not carbon, not reverse osmosis, not distillation. It requires industrial isotope separation.

Litewater Scientific produces deuterium depleted water at 10 PPM and 5 PPM — the lightest water on the planet, and the only DDW bottled in glass.

Deuterium depletion is the mechanism. Litewater is how you reach that state.

Clearest water you’ve ever jumped into. Same deuterium as your tap.

Every natural water source on earth carries it — spring, glacier, artesian, doesn’t matter. No filter takes it out. It takes an industrial separation process, which is the only reason these two bottles exist.

10 PPM and 5 PPM. The lightest water on the planet, and the only deuterium-depleted water bottled in glass.

How do you remove deuterium from water? You can’t filter it. You have to physically separate it — and it takes a 40-foot column to do it.

Deuterium is heavy hydrogen: a hydrogen atom with one extra neutron, roughly double the mass. It’s in every natural water source on Earth. The ocean-water standard, VSMOW, puts natural abundance at 155.76 ppm — about one deuterium atom per 6,400 hydrogen atoms.

The problem: deuterium is chemically almost identical to ordinary hydrogen. Reverse osmosis can’t separate it. Neither can carbon filtration or ordinary distillation — the molecules are too alike to sort by any normal method. That’s why DDW took decades to produce and why only a handful of facilities in the world can make it.

The one property you can exploit is weight. Heavy water is slightly less volatile than light water — it boils at 101.4°C versus 100°C, so it needs a touch more energy to ev***rate. When water turns to v***r, the lighter molecules leave first and the heavier deuterium stays behind in the liquid. Nature does a mild version of this in the water cycle, which is why rain and glacial meltwater are lighter than the ocean.

Litewater amplifies that tiny difference through Low-Temperature Vacuum Rectification. Purified artesian water climbs a sealed 40-foot column under vacuum. Inside, rising v***r and descending liquid meet hundreds of times — at each contact the light water tends up and the deuterium tends back down. One exchange does almost nothing. Hundreds, stacked, do everything. The published method (Titescu & Predescu, 1995) works the same way: two-stage vacuum rectification taking natural water under 80 ppm, then into the single digits.

The result is up to 97% of the deuterium removed — Litewater 10 PPM and 5 PPM, the most deuterium-depleted water in the world, bottled at the source.

Water, elevated.

Can a water filter remove deuterium? No. And that’s the part almost nobody knows.

Every glass of water you drink contains two kinds of hydrogen. Regular hydrogen, and a heavier isotope called deuterium — the same element carrying an extra neutron, which makes it about twice the mass. It’s measured against a global standard called VSMOW, and natural water runs roughly 150 parts per million of it (de Graaf et al., deuterium abundance in water). It has been in your water your entire life.

Here’s why your filter can’t touch it: deuterium isn’t a contaminant floating in the water. It is the water. Carbon filters trap chlorine and organics. Reverse osmosis separates by size and charge — and deuterium is nearly identical to regular hydrogen on both. Even distillation barely separates them, because the v***r-pressure gap between regular water and heavy water is tiny. Pulling deuterium down to a low level takes a different category of process entirely: multi-stage vacuum rectification, run through columns up to sixty feet tall, over many passes.

Why would anyone go to that trouble? Because of the kinetic isotope effect — an established principle in chemistry. Deuterium’s extra mass makes its bonds measurably harder to break, which slows hydrogen-transfer reactions. Inside your mitochondria, the enzymes that generate energy move hydrogen at enormous speed, partly through quantum proton tunneling in the respiratory chain — and deuterons tunnel roughly 20 times less efficiently than protons (Olgun, ATP synthase; deuterium-tunneling literature). Researchers propose that a lower deuterium load is associated with more efficient energy production, though the link to whole-body energy remains an inference rather than settled fact.

What is settled: the deuterium is there, no filter removes it, and getting your water down to a fraction of that natural level takes a process most people have never heard of.

Deuterium-depleted water (DDW) is how you get there. Litewater is the most deuterium-depleted water in the world.

The Deuterium-Depleted Diet: which foods are actually low in deuterium — and why leafy greens rank higher than butter.

Deuterium is a heavy, natural isotope of hydrogen that rides into your body on water. It’s in every food you eat, and the amount varies more than you’d think. The rule: the less water, sugar, and starch a food holds, the lower its deuterium.

That’s why fat wins. Tallow and lard (~116 ppm), grass-fed butter and ghee (~118), coconut and cold-pressed olive oil (~130) are built from carbon-hydrogen bonds with almost no water — the most deuterium-depleted foods there are. Burning fat also makes low-deuterium “metabolic water” (~118 ppm) inside your cells, while carb-heavy metabolism makes ~155 ppm. A fat-forward, lower-carb plate lowers deuterium two ways at once.

The low-deuterium food scale, lightest to heaviest:

Fats — tallow, lard, butter, ghee, coconut, olive oil (~116–130)
Proteins — grass-fed beef & lamb, wild fish, eggs, organ meats, poultry (~128–130)
Dairy — full-fat, cream, hard cheese, kefir (~130–136)
Low-sugar veg — leafy greens, cruciferous, asparagus, zucchini (~136–142)

Yes — leafy greens (~136) sit above the fats. They’re low for a plant, but plants store deuterium in their sugars, so even greens carry more than a structured fat. Top of the good range, not the bottom. For contrast: sugar ~146, wheat ~150, high-fructose corn syrup ~166.

Why it matters: researchers (Seneff & Kyriakopoulos, 2025; Boros et al.) propose cells work to keep deuterium out of mitochondrial water because it disrupts the ATP synthase nanomotor — associated with lower ATP and more oxidative stress. The kinetic isotope effect behind it is established science.

How to eat it: build plates around a natural fat and a grass-fed or wild protein, fill with non-starchy veg, shrink sugar and grains, cook with tallow, ghee, or olive oil, and steam over boil.

Diet lowers the deuterium you eat. Litewater lowers the deuterium you drink — reaching the levels food alone can’t.
