Sodium benzoatePreservative; can form trace benzene (a carcinogen) when combined with ascorbic acid; implicated in child hyperactivity studies.
SucraloseSweetener; emerging genotoxicity concern around the impurity/metabolite sucralose-6-acetate.
Phosphoric acidAcidulant (colas); high total phosphate intake linked to bone-mineral and renal concerns in some studies.
PolyphosphatesInorganic phosphate additives are highly bioavailable; high additive-phosphate intake is associated with increased cardiovascular and kidney burden, particularly in chronic kidney disease.
