    Does tea reduces the diuretic effect in comparison to coffee?

    The diuretic can be attributed to the caffeine present in tea and coffee. Caffeine increases diuretic action on the kidneys, increasing urinary volume and sodium extraction as a result of a decrease in the tubular re-absorption of sodium and water. Coffee contains a higher content of caffeine compared to tea. Research has shown that a 170ml (6-oz) serving of tea contains, on average 34mg of caffeine in comparison to 99 mg of caffeine in 170 ml serving of brewed coffee.

    As a result the diuretic effect of coffee is greater compared to tea.
