TL;DR

Hydrogen water can slow down the growth of the fungus C. albicans, which could make it a safe option for oral hygiene.

Key Finding

Hydrogen water significantly inhibited the growth of Candida albicans in laboratory conditions, reducing fungal proliferation compared to tap water at multiple time points.

Summary

Researchers tested hydrogen water—water infused with hydrogen gas through electrolysis—to see if it could slow the growth of Candida albicans, a fungus that causes oral infections. In laboratory dishes, hydrogen water significantly slowed fungal growth compared to regular tap water, though it did not prevent the fungus from forming protective layers called biofilms.

Practical Takeaway

This is an early laboratory study that has not been tested in humans or in the mouth. While the results are promising for potential oral hygiene applications, much more research—including human studies—would be needed before hydrogen water could be recommended as a treatment for fungal infections or oral health.

Abstract

Objectives: This study assessed the antifungal effects of neutral electrolysis hydrogen water, an agent known for its oral anti-bacterial effects on the growth of C. albicans in vitro. Methods: Hydrogen water, denture cleansing agent, and Listerine® were compared to a tap water control. We serially cultured C. albicans KCTC 27239 in SD media to analyze the inhibitory effect of each treatment on growth. We evaluated the data using repeated-measures ANOVA test and one-way ANOVA test, and a significant difference was defined as P<0.05. Results: Hydrogen water significantly inhibited the growth, but not the biofilm formation, of C. albicans compared to tap water control at 1-, 5-, and 10-minute time points (P<0.05). Conclusions: The growth of C. albicans was slower in hydrogen water than in tap water, thereby suggesting an inhibitory effect of hydrogen water. Hydrogen water may, therefore, be utilized as an antibacterial and preventive agent without any harmful effect on denture and oral tissues.
