Salt Substitutes ('Lite Salt')

Potassium: HigherPhosphorus: LowerSodium: Lower

The bottom line

The most dangerous swap in the kidney kitchen: sodium replaced by potassium chloride, in a product marketed as the healthy choice.

For everyone: Do not use any salt substitute unless your kidney team has specifically approved it for you. For people with high potassium or on medicines that raise potassium, these products can push potassium to dangerous levels.

A healthier swap

Salt-free herb and spice blends (check the label truly says salt-free and lists no potassium chloride), lemon, vinegar, garlic and smoked paprika.

These pages are general education about eating with kidney disease, dialysis or a kidney transplant. They are not medical advice and do not replace your own care plan. Kidney diets are individual: what is right for you depends on your stage, your blood tests, your medicines and your other conditions. Always talk to your care team or renal dietitian before changing what you eat, and never stop or change a medicine because of something you read here.
