The usual concentration of deuterium in water is about 144 ppm D/(D+H). It is known that the increasing of deuterium concentration in the body of living animals is a naturally  bioaccumulation process and could be enhanced by adding heavy water to their diet – with obviously dramatical changes in their health state. 
The aim of this study was to investigate how far could influence a deuterium-depleting agent the decreasing of the value of deuterium concentration at two different animals species (rat and chicken), to reduce the damages made by higher deuterium levels. The analyses results show that the deuterium depleting agent has effect on both species, but the rate of depletions is in correlation with a couple of factors, such as: species, age, the concentration of deuterium depleting agent, the period of administration of deuterium depleting agent.

Keywords: deuterium depleting agent (deuterium depleted water), deuterium spreading, mass analyses
