The Dietary Guidelines for Americans recommend limiting sodium intake to less than 2,300mg per day for most adults, roughly equivalent to one teaspoon of table salt. Many adults managing blood pressure or kidney health are advised even lower limits by their doctor.
Worked example
For a current intake of 1,800mg:
Percentage = 1800 / 2300 x 100 = 78.3% of daily limit
Remaining budget = 2300 - 1800 = 500 mg remaining
Frequently asked questions
Where does most dietary sodium come from? Processed and restaurant foods account for the large majority of sodium intake for most people, often far more than salt added at the table during cooking or eating.
Is 2300mg the right target for everyone? No - it is a general population guideline. People with hypertension or certain kidney conditions are frequently advised by their healthcare provider to target closer to 1,500mg per day.
