TL;DR
In a small 21-day human study, daily intake of hydrogen-rich water was associated with lower urine osmolality, hematocrit, and blood viscosity, suggesting possible improvements in hydration status and blood fluidity.
Key Finding
Drinking hydrogen-rich water for 21 days led to measurable decreases in blood viscosity (thickness) and urine osmolality (concentration) in both men and women, suggesting improved hydration status.
Summary
This small study looked at whether drinking hydrogen-rich water affected how well the body stays hydrated. Ten volunteers drank this special water for 21 days while researchers measured blood thickness, red blood cell concentration, and urine concentration. The researchers found that after drinking the hydrogen-rich water, participants' blood became less thick and their urine became more dilute, suggesting their bodies were better hydrated.
Practical Takeaway
This early human study suggests hydrogen-rich water may support hydration, but the findings come from only 10 people over 3 weeks, so larger and longer studies are needed before drawing firm conclusions. The changes observed in blood and urine markers were consistent, which is encouraging, but more research is necessary to understand whether these hydration improvements have meaningful health benefits.
Abstract (excerpt)
Objective: Aim: To demonstrate the effects of hydrogen-rich water (HRW) on hydration by examining hematocrit, blood viscosity, and urine osmolality. Patients and methods: Materials and Methods: Hydrogen Evodrop rich water (HEW), produced from a patented device with hydrogen concentration therein…
