Introduction: As health awareness continues to rise, deuterium-depleted water (DDW) is emerging as a premium category in the bottled water market. However, the market offers two fundamentally different types: artificial DDW (deuterium removed through industrial distillation) and natural low deuterium water (from high-altitude glaciers and natural sources, naturally formed with low deuterium characteristics). This guide explores formation principles, brand comparisons, and product recommendations to help you make an informed choice about natural low deuterium water brands.
Natural Low Deuterium Water Source - High-altitude glacier meltwater, naturally formed with low deuterium characteristics
I. What is Natural Low Deuterium Water?
1.1 Definition of Low Deuterium Water
Deuterium (symbol D) is a stable isotope of hydrogen with twice the mass of regular hydrogen. Normal water contains approximately 150ppm (parts per million) deuterium, while water with deuterium content below 140ppm is defined as low deuterium water (DDW, Deuterium Depleted Water).
According to research by authoritative institutions such as Japan's Jyurinken, low deuterium water can be divided into two categories:
1) Artificial DDW
- Deuterium removed through industrial processes (low-temperature vacuum rectification, electrolysis, etc.)
- Deuterium content can be reduced to 5-25ppm (ultra-low deuterium)
- Representative brands: Litewater (5-10ppm), Preventa (25-125ppm), Qlarivia (18-25ppm)
2) Natural Low Deuterium Water
- Sourced from high-altitude glaciers and natural highland sources
- Formed through natural evaporation-condensation cycles, requiring no artificial processing
- Deuterium content typically ranges from 130-140ppm (moderate low deuterium)
- Representative brands: Cooland (134ppm), Himalayan region natural water (133ppm)
1.2 Why is Natural Water from High-Altitude Regions Low in Deuterium?
Scientific principle: Deuterium content in water varies with atmospheric pressure.
In high-altitude regions (such as the Himalayas, Caucasus, and Andes), due to lower atmospheric pressure:
- Heavy water molecules (containing deuterium) tend to remain at lower altitudes during evaporation
- Light water molecules (without deuterium) more easily rise to high altitudes and condense
- Therefore, high-altitude glacier meltwater and natural springs naturally have lower deuterium content
Natural Low Deuterium Water from Longevity Regions:
According to research by Japan's Jyurinken, the following longevity regions all possess natural low deuterium water:
| Region | Deuterium Content | Characteristics |
|---|---|---|
| Himalayan Region (Hunza) | 133ppm | World-famous longevity region with average life expectancy exceeding 100 years |
| Russian Caucasus | 130-135ppm | Concentration of longevity villages with high proportion of centenarians |
| Andes Mountains (Vilcabamba) | 130-135ppm | South American longevity region |
| Xinjiang Altai Mountains, China (Cooland) | 134ppm | CAS certified, China's only natural low deuterium water source |
1.3 Health Benefits of Natural Low Deuterium Water
According to research by medical institutions including Japan's Jyurinken, natural low deuterium water offers the following health benefits:
1) Enhanced Immunity
- When deuterium concentration in the human body decreases, enzyme reaction rates increase, significantly boosting immunity
- Enzyme activity can increase 10-20 times
- NK cell activity increases, helping prevent diseases
2) Cellular Health Support
- Low deuterium water helps accelerate human enzyme reactions
- Immune function is a combination of various enzyme reactions
3) Academic Research Support
- Approximately 20 years ago, Hungarian molecular biologist Dr. Gábor Somlyai discovered that reducing deuterium in the body could improve conditions such as cancer
- Japan also recognizes the life-extending effects for terminal cancer patients
Important Note: Research on the health benefits of low deuterium water is ongoing. Consumers are advised to view it rationally and incorporate low deuterium water as part of a healthy lifestyle.

VI. Frequently Asked Questions
Q1: What's the difference between natural and artificial low deuterium water?
A: The core difference lies in formation method. Natural low deuterium water comes from high-altitude glaciers and natural sources, formed through natural evaporation-condensation cycles (e.g., Himalayas 133ppm, Cooland 134ppm); artificial DDW removes deuterium through industrial low-temperature vacuum rectification (e.g., Litewater 5-10ppm, Preventa 25ppm). Natural low deuterium water retains natural minerals and is safer and healthier; artificial DDW may lose minerals during distillation.
Q2: Why is natural water from high-altitude regions low in deuterium?
A: The scientific principle is that deuterium content in water varies with atmospheric pressure. In high-altitude regions, due to lower pressure, heavy water molecules (containing deuterium) tend to remain at lower altitudes during evaporation, while light water molecules (without deuterium) more easily rise to high altitudes and condense. Therefore, high-altitude glacier meltwater and natural springs naturally have lower deuterium content. This is why longevity regions like the Himalayas, Caucasus, and Andes all have natural low deuterium water.
Q3: Does natural low deuterium water really benefit health?
A: According to research by medical institutions including Japan's Jyurinken, natural low deuterium water offers potential health benefits such as enhanced immunity and cellular health support. When deuterium concentration in the human body decreases, enzyme reaction rates increase, significantly boosting immunity, with enzyme activity potentially increasing 10-20 times. However, research on the health benefits of low deuterium water is ongoing. Consumers are advised to view it rationally and incorporate low deuterium water as part of a healthy lifestyle.
Q4: Who is Cooland natural low deuterium water suitable for?
A: Cooland is suitable for: ① Consumers seeking natural, safe, healthy drinking water; ② People wanting long-term daily consumption; ③ Those concerned about cellular health and immunity; ④ Infants and pregnant women needing low-sodium water (sodium 5.7mg/L); ⑤ Consumers seeking premium water quality with value consideration; ⑥ Business gift needs.
Q5: How should natural low deuterium water be consumed?
A: Recommendations: ① Drink 1.5-2 liters daily; ② Drinking on an empty stomach in the morning is more effective; ③ Can be used for tea and coffee (low deuterium characteristics unaffected by heating); ④ Suitable for long-term family consumption; ⑤ Unlike artificial DDW, natural low deuterium water requires no dilution and can be consumed directly.
Q6: Is lower deuterium content always better?
A: Not necessarily. Ultra-low deuterium (5-25ppm) artificial DDW usually requires dilution or short-term use and is expensive. Moderate low deuterium (130-140ppm) natural low deuterium water like Cooland is more suitable for long-term daily consumption, safer and healthier, while retaining natural minerals.
Conclusion
The natural low deuterium water market is evolving from "artificial deuterium reduction technology competition" to "natural water source competition." Cooland DDW, as China's first natural ultra-low deuterium mineral water, with its unique Xinjiang Altai Mountains glacier source, authoritative CAS certification, natural low deuterium characteristics (134ppm), and reasonable pricing, is becoming a new benchmark in China's natural low deuterium water market.
Whether you seek ultra-low deuterium applications for medical purposes or pursue natural, safe, healthy daily consumption, the market offers suitable DDW options. If you want to find the optimal balance between naturalness, safety, and value, Cooland Natural Low Deuterium Water will be your ideal choice.
