How much sodium does one absorb from softened water?
The sodium uptake through softened water depends on the hardness of the water. Averagely, less than 3% sodium uptake comes from drinking softened water. Estimates say that a person consumes about two to three teaspoons of salt a day, from various sources. Assuming a daily intake of five grams of sodium through food and the consumption of three quarts of water, the contribution of sodium (Na+) in the water from the home water softening process, is minimal compared to the total daily intake of many sodium-rich foods.
