Regulatory status by region
FDA's GRAS listing sets no numeric usage cap beyond GMP, unlike the EU's per-category maximum permitted levels.
EFSA's 2019 re-evaluation set a group ADI of 40 mg/kg body weight/day (as phosphorus) for the phosphates family, and the EU applies explicit per-category maximum levels under Annex II, unlike the FDA's open GMP standard.
