Hydrogen vs. Caffeine for Improved Alertness in Sleep-Deprived Humans
Study Type
Cross over study
IMPLICATION
Sleep-deprivation relief; DrinkHRW improves alertness and executive function in sleep-deprived people with persistent results, while caffeine’s executive function improvement dropped after 15 min. DrinkHRW might be a better alternative to caffeine for fatigue and cognitive deficits from sleep deprivation.

The Effects of 12-week Hydrogen-Rich Water Intake on Body Composition, Short-Chain Fatty Acids Turnover, and Brain Metabolism in Overweight Adults: A Randomized Controlled Trial
Study Type

IMPLICATION
HRW may improve gut inflammation, improve the gut flora towards ones that produce more SCFA. The SCFA acts in the brain and mitochondria to help with body composition, metabolic health, and waist circumference in middle-aged overweight adults. N-acetylaspartate, a marker of neuronal functions, also went up in several brain regions.
