Above the tolerable upper limit. Risk of adverse effects — back off or consult a clinician.
You're at 0% of your phosphorus target. The biggest single-serving sources to top it off:
Second most abundant mineral after calcium; ~85% in bone as hydroxyapatite, the rest in cell membranes (phospholipids), nucleic acids (DNA/RNA backbone), and high-energy phosphate compounds (ATP, creatine phosphate). Dietary insufficiency is essentially absent in modern diets — the concern is excess from phosphate additives.
Inorganic phosphate is the universal currency of cellular energy. ATP hydrolysis releases the gamma phosphate, powering nearly every endergonic reaction. Plasma phosphate is regulated by PTH, FGF23, and vitamin D — chronic excess relative to calcium drives bone resorption and vascular calcification (particularly in CKD).
Rare in unrestricted diets. Hypophosphatemia occurs in refeeding syndrome, alcoholism, severe burns, DKA recovery, and with phosphate binders.
Chronic high intake (especially from phosphate additives in processed food and cola) drives vascular calcification and bone loss in CKD. UL is 4,000 mg/day for adults.
Standalone phosphorus supplementation is rarely warranted outside clinical hypophosphatemia. Read processed-food labels: 'phosphoric acid', 'sodium phosphate', 'pyrophosphate' all count and absorb at near-100%. Whole-food phosphate intake is balanced by calcium and protein; processed-food phosphate is not.
Animal-source organic phosphate ~60% bioavailable; plant phytate-bound phosphate ~20–40%; inorganic additives ~90%. The bioavailability gap explains why processed-food phosphorus overshoots even when total mg looks similar.
Adequacy is universal; excess is the modern issue. High serum phosphate (even within normal range) tracks with cardiovascular events and accelerated aging biomarkers. Population-level move toward whole foods would likely lower phosphate exposure without measurement.
