PROBLEM TO BE SOLVED: To provide drinking water that uses deuterium (D2) to reduce active oxygen or the like in the body for maintaining health, and also allows the efficacy of a taken medicine to continue.SOLUTION: Drinking water comprises a deuterium component concentrated and separated from natural water, as heavy water (D2O) and deuterium sulfuric acid (D2SO4), the content of the heavy water (D2O) being 0 vol.%-0.4 vol.%, the content of the deuterium sulfuric acid (D2SO4) being 0 vol.%-0.4 vol.%, and the total content of these compounds being 0.0001 vol.%-0.4 vol.% in the natural water.COPYRIGHT: (C)2016,JPO&INPIT【課題】重水素(D2)を用いて、体内の活性酸素等を還元させて健康を維持し、摂取した医薬の効能を持続させることの可能な飲料水を提供する。【解決手段】 天然水から濃縮、分離して得た重水素成分を、重水(D2O)及び重水素硫酸(D2SO4)として含有し、重水(D2O)を0体積%~0.4体積%含有し、重水素硫酸(D2SO4)を0体積%~0.4体積%含有し、これら化合物全体で天然水に0.0001体積%~0.4体積%含有した。【選択図】なし
