Deuterium-Depleted Water (DDW) is water with deuterium content below 140ppm.

Normal drinking water contains about 150ppm deuterium (150 deuterium atoms per million hydrogen atoms). DDW reduces deuterium concentration to minimize interference with cellular metabolism.

Yes, natural DDW exists in nature. Due to evaporation-condensation processes in the water cycle, glacier water in high-latitude, high-altitude regions has lower deuterium content. For example, Antarctic glacier water has about 89ppm deuterium, and Altai Mountain Kelan River glacier water is also a natural low-deuterium source. Cooland DDW comes from this precious water source.

Scientific research shows DDW regulates cellular oxidative stress through the Keap1-Nrf2 signaling pathway, affecting antioxidant gene expression. Low-deuterium environments support mitochondrial ATP synthesis efficiency and normal cellular metabolism.

A 2024 Nutrients journal systematic review summarized 15 studies confirming DDW's cellular protective effects.

DDW is safe drinking water. Deuterium is a naturally occurring element, and reducing its concentration doesn't produce harmful substances. DDW is suitable for daily consumption by all groups, including health-conscious adults, seniors, and athletes. Pregnant women and infants with concerns should consult a doctor.

Yes, DDW has extensive global scientific research support. For example, the 2024 Nutrients journal article "Deuterium-Depleted Water in Cancer Therapy: A Systematic Review of Clinical and Experimental Trials" summarized 15 preclinical and clinical trials over 15 years, confirming DDW's health potential. The Chinese Academy of Sciences has also tested and certified Cooland's water source.

We recommend drinking 1.5-2 liters of DDW daily to replace regular drinking water. Specific amounts can be adjusted based on body weight, activity level, and health conditions. Continuous consumption for 3-6 months helps body deuterium concentration reach equilibrium for optimized cellular metabolism.

Yes. Deuterium is a hydrogen isotope, and its concentration doesn't change with heating or boiling. DDW can be used for tea, coffee, cooking, etc., without affecting its low-deuterium properties. However, to preserve optimal taste and vitality, avoid prolonged high-temperature boiling.

Store DDW in a cool, dry place away from direct sunlight and heat. Keep sealed. Consume promptly after opening. Cooland DDW typically has a 24-month shelf life �?check the package for specific dates.

Natural DDW: Sourced from specific geographical environments (like high-latitude glaciers), formed through natural water cycles over thousands of years, retaining natural minerals and activity. Cooland DDW comes from Altai Mountain Kelan River glaciers.

Artificial DDW: Produced through industrial distillation, electrolysis, or other methods to remove deuterium, which may remove natural minerals. Main production countries include Russia, Romania, and Hungary. Cooland insists on natural sources without artificial deuterium removal.
