The study examined the effects of drinking an alkaline, mineral-rich bottled water on acid-base balance and hydration in young adults. Subjects were split into a control group that drank regular bottled water and an experimental group that drank the alkaline water for two weeks. The experimental group showed significant increases in blood and urine pH levels and decreases in urine output, indicating improved acid-base balance and hydration. In contrast, the control group showed no changes. The results suggest that regularly drinking alkaline water may benefit acid-base balance and hydration.

Background
The present study sought to determine whether the consumption of a mineral-rich alkalizing (AK)
bottled water could improve both acid-base balance and hydration status in young healthy adults under
free-living conditions. The AK water contains a naturally high mineral content along with Alka-
PlexLiquid™, a dissolved supplement that increases the mineral content and gives the water an alkalizing
pH of 10.0.
Methods
Thirty-eight subjects were matched by gender and self-reported physical activity (SRPA, hrs/week) and
then split into Control (12 women, 7 men; Mean +/- SD: 23 +/- 2 yrs; 7.2 +/- 3.6 hrs/week SRPA) and
Experimental (13 women, 6 men; 22 +/- 2 yrs; 6.4 +/- 4.0 hrs/week SRPA) groups. The Control group
consumed non-mineralized placebo bottled water over a 4-week period while the Experimental group
consumed the placebo water during the 1st and 4th weeks and the AK water during the middle 2-week
treatment period. Fingertip blood and 24-hour urine samples were collected three times each week for
subsequent measures of blood and urine osmolality and pH, as well as total urine volume. Dependent
variables were analyzed using multivariate repeated measures ANOVA with post-hoc focused on
evaluating changes over time within Control and Experimental groups (alpha = 0.05).
Results
There were no significant changes in any of the dependent variables for the Control group. The
Experimental group, however, showed significant increases in both the blood and urine pH (6.23 to 7.07
and 7.52 to 7.69, respectively), a decreased blood and increased urine osmolality, and a decreased urine
output (2.51 to 2.05 L/day), all during the second week of the treatment period (P [less than] 0.05).
Further, these changes reversed for the Experimental group once subjects switched to the placebo
water during the 4th week.
Conclusions
Consumption of AK water was associated with improved acid-base balance (i.e., an alkalization of the
blood and urine) and hydration status when consumed under free-living conditions. In contrast, subjects

results indicate that the habitual consumption of AK water may be a valuable nutritional vector for
influencing both acid-base balance and hydration status in healthy adults.
