Linked to getting too much

Where an excess of Phosphorus is linked — 4 sources.In the order the Map holds them: strongest evidence first. That is a statement about the evidence, not about what matters most.

Phosphorus	Don't overdo	Strong	Established clinical	Hyperphosphatemia (chiefly in kidney disease, worsened by phosphate additives) drives vascular and soft-tissue calcification, arteriosclerosis and cardiovascular mortality; general-population high intake shows similar associations.
