N2 - Background/Objectives: Calcium and vitamin D are important for bone health. We compared 24-hour urinary calcium-excretion (Uca/24hrs), during dietary calcium steady-state condition, for different calcium-sources and effects of vitamin D, age and sex.Subjects/Methods: Fifty-two healthy pre- and postmenopausal women and men completed the regimens: placebo, calcium carbonate (400mg) +18μg vitamin D, calcium carbonate (400mg) +38μg vitamin D and 400mg calcium phosphate (milk). Uca/24hrs was measured during dietary calcium steady state as a surrogate measure of calcium-absorption. Serum-calcium, parathyroid hormone (PTH), 25-hydroxy-vitamin D, Procollagen Type 1 N-terminal Pro- Peptide (P1NP) and C-terminal Telopeptide of type 1 collagen (CTX) were measured.Results: Mean daily intake of calcium for the study group ± SD was 1105 ±396 mg. Mean-Uca ± SD: placebo 5.19 ± 2.04 mmol/24hrs, milk 5.88 ± 2.39 mmol/24hrs, (CaCO3+D) 6.19 ± 2.34 mmol/24hrs and (CaCO3 + DD) 6.26 ± 2.32 mmol/day. Uca were higher for all regimens compared to placebo (p <0.001), no difference was found between regimens. CTX was lower during all regimens compared to placebo (p <0.001): placebo 450 ± 243 μg/L, Milk 377 ± 248 μg/L, (CaCO3+D) 392 ± 266 μg/L and (CaCO3+DD) 361 ± 232 μg/L.Conclusions: Uca was higher during supplementation with calcium compared to placebo. Supplementation with calcium reduced bone resorption significantly without effecting PTH. Menopausal status, sex and supplement with vitamin d demonstrated no effect on calcium excretion.
