The extremely positive effect of hydrogen-rich drinking water has been proven several times in studies and the successes in many health applications are convincing. Molecularly dissolved hydrogen in drinking water is considered a fountain of youth, natural anti-aging and performance-enhancing at work, in leisure time and in sports. Mobile hydrogen boosters have the advantage of being usable at home, in the office and on the go. The high H2 saturation only lasts for a short period of time and therefore a fresh enrichment is always better than drinking stale water. In the meantime, mobile hydrogen generators have achieved very good values that even exceed those of fixed H2 stand-alone devices. We are comparing two hydrogen boosters here.
