Variations in the mineral concentrations in breast milk during a single nursing, diurnally and on consecutive days.
The concentrations of ionized calcium, total calcium, magnesium, sodium and potassium were measured in breast milk collected from 20 women, 4 to 28 weeks post-partum. No significant differences were found in the mineral concentrations in fore and hind milk. Diurnal variations occurred randomly, with no systematic cyclic changes within the 24-h period and the pattern varied from day to day.
