PROBLEM TO BE SOLVED: To address the problem that conventionally, hydrogen could not be efficiently absorbed by the human body because it was not possible to control the generation of hydrogen, by providing a hydrogen containing substance which allows the easy absorption of hydrogen into the human body.SOLUTION: A porous silica or coral calcium is mixed with γ-polyglutamic acid, tableted and solidified. Furthermore, it is preferable to make a nucleated tablet with a luminacoid as the outer shell.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】従来、水素の発生を制御することができなかった為、効率よく水素を人体へ吸収することができなかった。そのため、人体に水素を吸収しやすい水素含有物を提供する。【解決手段】多孔質シリカやサンゴカルシウムにγ-ポリグルタミン酸を混合したものを打錠固化する。さらにルミナコイドを外殻とした有核錠剤とすればなおよい。【選択図】図2
