title: [Circadian changes in levels of magnesium in serum of healthy individuals].
abstract: Circadian changes in blood serum magnesium levels in healthy individuals. We examined circadian changes of the serum magnesium in 20 healthy subjects. Blood samples were taken every second hour during the 24 hours. Male serum magnesium concentrations increased from the lowest level (0.810 +/- 0.035 mmol/l) observed at 8.00 am to the highest level (1.028 +/- 0.084 mmol/l) at 6.00 pm. Female-we observed two peaks of serum magnesium concentrations: first at 8.00 pm (0.992 +/- 0.103 mmol/l) and second at 4.00 am. (0.982 +/- 0.094 mmol/l) with the lowest level at noon) 0.789 +/- 0.043 mmol/l. Differences between extreme levels were statistically significant.
