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 anti-inflammatory, binds free radicals and is considered a fountain of youth, natural anti-aging and performance-enhancing at work, in leisure and in sports. Mobile hydrogen boosters – also called hydrogen bottle – 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 hydrogen boosters. The comparison of hydrogen inhalers and Brown’s gas is here.
