Sodium and potassium in a daily diet
For adults, WHO recommends less than 2000 mg sodium and at least 3510 mg potassium per day. Molar ratio: (Na, mg / 23) / (K, mg / 39.1). Approximate salt equivalent: sodium, mg × 2.5 / 1000. The ratio is displayed without an individual risk category.

How it is calculated
For adults, WHO recommends less than 2000 mg sodium and at least 3510 mg potassium per day. Molar ratio: (Na, mg / 23) / (K, mg / 39.1). Approximate salt equivalent: sodium, mg × 2.5 / 1000. The ratio is displayed without an individual risk category.
Formula
For adults, WHO recommends less than 2000 mg sodium and at least 3510 mg potassium per day. Molar ratio: (Na, mg / 23) / (K, mg / 39.1). Approximate salt equivalent: sodium, mg × 2.5 / 1000. The ratio is displayed without an individual risk category.
Limits of the method
Enter intake from food for one day, not blood or urine concentrations. Do not automatically apply the general potassium reference when excretion is impaired, with kidney disease or potassium-altering medication. Hypertension alone does not define a new individual target here.
