Sodium salts of phosphoric acid — used as buffers, emulsifying salts in processed cheese, and texturizers.
Why we flag it amber
It's permitted and generally considered safe, but there are a few reasons to be mindful — like sensitivities in some people, debated studies, or intake limits. The Safety section below explains the specifics.
Safety profile
ADI of 70 mg/kg body weight as phosphorus (combined phosphates). Long-term high phosphate intake from ultra-processed foods is observationally associated with cardiovascular and renal effects — particularly relevant in chronic kidney disease.
