Provided is a method for producing active hydrogen-dissolved water, which can easily produce active hydrogen-dissolved water that stably maintains a strong antioxidant effect for a long period of time. A method for producing active hydrogen-dissolved water comprising a step of activating dissolved hydrogen in an aqueous solution by a catalytic reaction with a hydrogen adsorption / occlusion metal colloid. Here, the hydrogen adsorption / occlusion metal colloid is preferably one or more hydrogen adsorption / occlusion metal colloids selected from the group consisting of platinum colloid, palladium colloid, vanadium colloid, iron colloid, and silicate colloid.
