Semi heavy water, also known as deuterium-depleted water (DDW), is a type of water in which the concentration of deuterium, an isotope of hydrogen, is diminished compared to regular water. Deuterium is a hydrogen isotope with an additional neutron in the nucleus, giving it a slightly greater atomic mass than the more common isotope, protium.
In semi heavy water, the ratio of deuterium to regular hydrogen (protium) is reduced, typically below the natural abundance of deuterium found in ordinary water, which is around 155 parts per million. However, there is no universally agreed threshold for defining semi heavy water, and the term is not widely recognized within the scientific community.
Some proponents of semi heavy water claim that it may have various health benefits, including anti-aging properties and improved cellular functions. However, scientific studies supporting these claims are limited, and further research is necessary to fully understand the potential effects of drinking semi heavy water.
It is worth noting that semi heavy water should not be confused with heavy water (D2O), which has a significantly higher concentration of deuterium atoms and plays a critical role in certain industrial and scientific applications, such as nuclear reactors and nuclear magnetic resonance (NMR) spectroscopy.
