Phosphorus

Routine annual

also phosphate

What it isPhosphorus circulates mostly as phosphate. The body uses it in bone mineralization, in ATP, in DNA, and in cell membranes.

DoesCo-mineralizes bone with calcium, powers ATP-based energy transfer, structures DNA, and supports membrane phospholipids.

GoodMid-range phosphate signals balanced kidney and parathyroid and adequate bone mineral handling.

BadHigh phosphate in chronic kidney disease drives vascular calcification and predicts cardiovascular mortality. Low phosphate is rare but causes muscle weakness and bone pain.

Standard

2.5–4.5 mg/dL.

Optimal

3.0–3.8 mg/dL (narrow target)

Modifiers

Rises in kidney disease and with vitamin D excess; falls with refeeding syndrome.

How to optimize

Lifestyle: —
Diet: Avoid excess phosphate additives in ultra-processed food and colas; whole-food phosphate (in meat, dairy, beans) is well-handled.
Supplements: —
Peptides: —
Drugs: Phosphate binders in CKD.
