Potassium citrates

Group: Acidity regulators

Harm level1 of 5No concern

In plain words

Potassium citrates are potassium salts of citric acid. They regulate acidity and appear in drinks, sweets, dairy products and reduced-sodium foods.

Where you find it: drinks, jams, confectionery, canned food

Our recommendation

No need to avoid them; people with kidney disease should be careful.

Possible risks and effects

  • No relevant risk known at normal intake.
  • People with kidney disease who must limit potassium should be careful.

For experts

Mono- and tripotassium salts of citric acid acting as acidity regulators, stabilisers and sequestrants. They are permitted at quantum satis in the EU and are not considered a safety concern. Their potassium matters mainly for people with kidney disease.
