Common Effects of Caffeine

9. Reduce Kidney Stone Risk

The liver isn't the only excretory organ that benefits from caffeine. Studies link moderate caffeine consumption to fewer incidences of kidney stones. Caffeine dilutes urine, reducing the concentration of toxins that cause kidney stones. This can lead to those compounds being safely removed from the body instead of remaining in the kidneys and turning into painful deposits. Studies also indicate a link between the progression of kidney disease and caffeine consumption. Caffeine-consuming people with kidney disease show a slower progression, as well as a lower mortality rate.
