Sodium citrate
Sodium citrate is a sodium salt of citric acid used to control acidity and keep food mixtures stable. It helps cheese melt smoothly and can bind metal ions. Labels may use a general name without identifying the exact salt or water content.
Also known as
Sodium citrates · Trisodium citrate · Trisodium citrate dihydrate · Monosodium citrate · Sodium dihydrogen citrate · Disodium citrate · Disodium hydrogen citrate
Why PRūF tracks it
Higher sodium citrate intake was associated with a small increase in diabetes risk in one observational cohort, but causation is unproven; stomach discomfort reported after large supplemental doses does not establish harm from ordinary food use.
Read the research
Sodium citrate helps control acidity and texture in foods, especially processed cheese and drinks. The name can cover related sodium salts of citric acid; it does not mean citric acid itself or every citrate salt. Food labels rarely identify the precise form or amount. JECFA assigned citric acid and its sodium salts a group acceptable daily intake described as not limited, reflecting its historical assessment of low toxicity under evaluated food uses, rather than permission for unlimited consumption.
The United States permits specified food-grade sodium citrate under good manufacturing practice. More recent research raises a narrower uncertainty: a French observational study associated higher sodium citrate intake with a small increase in type 2 diabetes risk. Later analyses linked additive mixtures containing sodium citrates with diabetes or hypertension, but cannot isolate the effect of sodium citrate. These studies overlap in their underlying cohort and do not prove causation.
Large supplemental doses can also cause stomach discomfort and alter blood acid balance; those exposures should not be treated as ordinary meal quantities. Restaurant ingredient statements establish disclosure, not a measured dose or personal risk.
