TL;DR
This study explores whether drinking a special type of water with active hydrogen, called natural reduced water, can improve mental abilities, body health, and mood in older adults.
Key Finding
This is a study protocol describing a planned trial; results are not yet available.
Summary
This study is testing whether natural water containing active hydrogen (a type of water found in Japan called Hita Tenryosui water) can improve thinking skills, body composition, and mood in people aged 65-74. Researchers will have some participants drink 1 liter of this special water daily for 6 months, while others drink regular tap water, and then measure changes in their cognitive function, body composition, and psychological well-being.
Practical Takeaway
This study has not yet been completed or published with results, so there is no evidence to evaluate at this time. Once the trial is finished and results are published, it may provide early human evidence about whether hydrogen-rich water affects cognitive function or body composition in older adults—though a single 6-month study would be preliminary.
Abstract (excerpt)
Natural reduced water is natural water that contains active hydrogen and reduces oxidation. It is rare in the world, and in Japan, it is produced in the Hita area of Oita Prefecture (Hita Tenryosui water). Previous studies in humans have examined the effects of natural reduced water on diabetes…
