The form“Why Phosphorus — not Calcium Carbonate or Calcium Phosphate?”Evidence Strong evidence

Phosphorus is the strongest evidence signal for this outcome.

  • PhosphorusThe pick

    Strong evidence · 270 mg

    Essential mineral tracked on nutrition labels; critical for bone and tooth mineralization, ATP energy production, and cell membrane phospholipids.

  • Calcium Carbonate

    Strong evidence · 650 mg (calculated)

  • Calcium Phosphate

    Strong evidence · 750 mg

    A calcium-phosphorus mineral salt with lower calcium bioavailability than citrate or malate; common in food fortification and some bone supplements.
