  Effect of calcium carbonate particle size on calcium

  The parathyroid hormone suppression curve from the small particle versus placebo arm indicated that calcium absorption from small particle size CaCO(3) was greater than placebo. Calcium balance (Ca intake urine Ca fecal Ca ) demonstrated that the small particle size CaCO(3) supplement increased Ca retention nearly 2-fold compared with placebo (p < 0.05 496 ± 213 and 256 ± 94 mg/d respectively).
