What is Deuterium-Depleted Water (DDW)?

Deuterium-Depleted Water (DDW) is water with deuterium content below natural levels. Deuterium is a stable isotope of hydrogen with a proton and neutron in its nucleus, making it about twice the mass of regular hydrogen (protium) - hence the name "heavy hydrogen."

According to Wikipedia, Vienna Standard Mean Ocean Water (VSMOW) has a deuterium concentration of 155.76ppm, while Standard Light Antarctic Precipitation (SLAP) is just 89.02ppm. Academics generally define water with deuterium below 140ppm as deuterium-depleted water.

Water Type Deuterium Boiling Point Density Source
Cooland DDW ~134 ppm <100°C <1.0g/mL Altai Glaciers
Tap Water 140-155 ppm 100°C 1.0g/mL Surface/Ground
Ocean Water 155.76 ppm 100°C 1.0g/mL Oceans
Antarctic Ice 89.02 ppm <100°C <1.0g/mL Antarctica
Heavy Water ~100% 101.4°C 1.105g/mL Industrial

The Science Behind DDW

The following is excerpted from scientific literature and is not a product efficacy claim.

Aquaporin Research: 2003 Nobel Chemistry laureate Peter Agre discovered aquaporin proteins in cell membranes, revealing how water molecules cross membranes. Some studies discuss the relationship between structured small-cluster water and aquaporins.

相关研究通路 Signaling Pathway: According to a 2024 systematic review in Nutrients journal, some experimental models discuss ROS levels, related gene expression, and the 相关研究通路 signaling pathway. This is literature background only, not a product efficacy statement.

Mitochondrial Energy Metabolism: Literature discusses deuterium isotopes and basic mechanisms related to mitochondrial ATP synthase and energy production efficiency. The official site does not extend these points into human efficacy claims.

01

DNA Structure Impact

As a stable hydrogen isotope, deuterium is heavier than ordinary hydrogen. Some basic studies discuss its effects from the perspectives of isotope composition, molecular structure, and experimental models. The official site presents this as scientific background only.
02

Cellular Metabolism

Some studies discuss how deuterium-related isotope composition may affect enzyme catalysis and biochemical reactions in experimental models. The official site does not extend these points into human efficacy claims.
03

Mitochondrial Function

Literature discusses deuterium isotopes and basic mechanisms related to mitochondrial ATP synthase and energy production efficiency. The official site does not extend these points into human efficacy claims.
04

相关研究通路 Pathway

Some studies discuss the 相关研究通路 signaling pathway, ROS levels, and antioxidant gene expression in experimental models. The official site does not extend these points into human efficacy claims.
Cooland DDW Water Source
Cooland DDW originates from Kelan River glaciers in the Altai Mountains - a glacier influenced by both Atlantic and Arctic air masses. Through extensive sampling at the Dadongou Valley, the Chinese Academy of Sciences confirmed deuterium levels of δD -150‰ to -90‰, making it a premium low-deuterium water source.
