 note = {Urinary excretion of calcium and magnesium were measured in order to examine the possibility of biological monitoring of six males aged 29-49 years old. This study showed the possibility of estimating the amount of calcium intake by determining urinary excretion of calcium. In regard to magnesium, since there was little change within a day compared with calcium, the possibility was low. Amount of urinary calcium and magnesium excretion corrected for creatinine could also be estimated by the spot urine. Ca/Mg molar ratio in urine was smaller than one before eating meals and after a meal becomes larger than one.},
