Abstract

Fourteen normal subjects took 1000 mg calcium orally as calcium citrate or calcium carbonate. The amount of calcium absorbed was estimated from the rise 1n urinary calcium. The urinary calcium following calcium citrate load significantly higher (by 20-66%), whether expressed as the total amount or as the Increment above basal (fasting) excretion. Thus, calcium citrate provides a more optimum calcium b1o-availability than calcium carbonate.
