PROBLEM TO BE SOLVED: To provide a hydrogen-containing drink which maintains a high density of dissolved hydrogen in a hydrogen-containing drink containing functional ingredients such as teas and hydrogen water.SOLUTION: A hydrogen-containing drink is made by compounding at least one type of functional ingredient which is selected from the group consisting of: teas fruits, vegetables and plants sugars and sweeteners polyphenols vitamins and coenzymes amino acids and proteins oxidation-reduction enzymes and citric acids and yeast extracts with hydrogen water. The hydrogen-containing drink is prepared by producing hydrogen water by deaerating water as a raw material and dissolving hydrogen gas in it through a gas-permeable hollow fiber membrane and dissolving or mixing one of the above functional ingredients in or with the produced hydrogen water. Alternatively, it is prepared by dissolving or mixing one of the above functional ingredients in or with water as a raw material, deaerating it and dissolving hydrogen gas in it through the gas-permeable hollow fiber membrane.
