What is deuterium ‘D’?
(get from standard definitions). The first hydrogen isotope is named ‘protium’ (the most abundant by far and the lightest), consisting of a proton and an electron. Protium is commonly expressed by the symbol '1H’. The second isotope is named ‘deuterium’ (much less abundant than protium but twice as heavy due to the addition of a neutron).
Hydrogen Isotopes
Prevalence of hydrogen isotopes on Earth:
Protium - 99.98% (by number)
Deuterium - 0.0156% (by number)
On our planet, for every 1,000,000 atoms of Hydrogen there are about 150 atoms of deuterium, (150 ppm).
Deuterium Concentration on Earth

What is ‘parts-per-million’ or ‘ppm’?
‘Parts-per-million’ means ‘out of a million’. It is commonly used to describe the concentration of something in a solution of water. One ppm is equivalent to 1 milligram of something per liter of water.
What is water?
What we commonly refer to as water, consume every day, use to prepare foods and beverages, irrigate our lawns, wash our clothes and put out fires, is more complex in its composition than is indicated by the popular chemical formula “H2O”. Chemically speaking, natural water predominantly consists of three molecules: H2O, HDO and D2O, and if you consider all the isotopes of oxygen and the various configurations, there are really 63 different types of water molecules known, in approximately the following ratios.
Breakdown of Hydrogen Isotopes in Earth's Water
What is light water?
What is heavy water?
Heavy water is a term given to a unique composition of water in which the natural deuterium content is concentrated by separating it from the light water (the protium rich water). Heavy water is used in the atomic energy industry and atomic bombs as a ‘neutron moderator’.  Ice cubes made from heavy water will sink to the bottom instead of float on the surface.
What is Litewater ? 
Litewater is our brand of deuterium-depleted water (DDW). It is water which has a lower concentration of deuterium than occurs naturally. Scientists, studying the cause of aging, discovered that even when a small amount of Deuterium containing Heavy Water is removed from normal water, the benefits are profound. Excess deuterium interferes in all biological process and is known to damage the mitochondria over time. Daily consumption of Litewater eliminates deuterium interference. Litewater has a 94-97% lower concentration of deuterium than regular water.
Why is Litewater so expensive?
Where is Litewater produced?
Litewater is produced in our facility in a remote area of Russia. Water is obtained from a natural artesian well, purified by membrane technology and then processed using the method described above to separate the deuterium to create Litewater.  It is analyzed and verified for deuterium depletion, then bottled at the source and shipped to North America and other global locations. 
Does light water exist in nature?
How is Litewater different than other brands of deuterium depleted water?
We offer the lowest available concentration of deuterium (most depleted) in the world. Our water is in a category below 25 ppm which is often referred to as ‘super light water’.  
How do I know Litewater is truly deuterium depleted to 5 & 10 ppm?
Every batch is tested before bottling and we guarantee accuracy to within ±3 ppm. We use the world’s most advanced stable isotope testing equipment known as fourth-generation cavity ringdown spectroscopy (CRDS) for unsurpassed precision and high accuracy. We test at our facility and also verify our results in the U.S. at an independent 3rd party lab. Click here for a lab report. 
Is Litewater safe for everyone?
Can Litewater be combined with medication and supplements?
Yes, there are no restrictions on use and it is even desirable. Because Litewater is excellent in assisting the natural healing abilities of the body it can help any medication or supplement work even better.
Are there any side effects to Litewater?
Litewater is the closest to the water we make ourselves deep in our cells. It is the purest, cleanest water that exists, free of all impurities and this has a positive effect on the body. With regular consumption of Litewater, a more complete purification of the whole body from deuterium occurs. This process may assist to increase the functional activity of cells, organs and some body systems.
Does Litewater have a distinctive taste?       
Litewater is deuterium depleted distilled water and has no specific taste, there are no impurities or flavorings in it. However many people have expressed that it “feels cleaner” on the palette. You can add Quinton or QuintEssential ocean minerals & trace elements for additional health support or use Celtic sea salt for more taste.
Can Litewater be heated, boiled or frozen like natural water?
Litewater can be used like any other water. Freezing, heating, boiling will not affect the deuterium levels of Litewater. Only dilution with other liquids will impact the amount of deuterium in the water.
Are there any other precautions to be taken with Litewater?
Litewater is perfectly safe for everyone, although if you are pregnant, nursing, or have an illness, always consult your doctor or medical professional before embarking on any deuterium depletion protocol.
How much Litewater or Litewater-Mix should I consume?
1/2 to 1 liter per day of 10 ppm diluted to 100 ppm is a excellent amount to deplete your deuterium levels to 131 ppm over a period of 45 days. Keep in mind the Hunza people which were studied for their great health and extreme longevity drank glacier water of @135 ppm total deuterium.  People that want to deplete their deuterium levels faster and lower will dilute to 80 ppm or below, and drink that every day. Studies by Russian scientists also show that 1/2 - 1 liter per day of 5 to 10 ppm for 7 days per month is very effective as well to manage the total body burden of deuterium. The chart below will help you with how to dilute properly for the deuterium depletion level desired as well as the corresponding cost and time to the desired depletion level.  
When would I want to use Litewater 5 vs. Litewater 10?
Litewater 5 is for immediate effect, for athletes, biohackers, weekend warriors, to be taken when a boost in mental and physical performance is needed immediately. Litewater 10 is for long term use, as a concentrate, diluted to achieve the desired level of deuterium depletion.
Where can I find more research on Litewater?
Within the last 50 years, the leading research institutes in Hungary, UK, Japan, China, France, the USA, Russia. and other countries have been studying biological properties of light and heavy water. The first known study linking deuterium depletion to increased wellness and longevity was published in Russia in 1966. Dozens of studies on deuterium depleted water exist and are readily available via a search on the world wide web.
