Abstract
Net absorption of Ca,Mg and P was measured in three low birth-weight babies with no major problems, during periods of 3 days in the 3rd week of life. Their formula was supplemented with 800 mg of calcium-magnesium lactate. Five control babies were on the same formula,the mineral content (mean± SD) of which was:Ca 76.26±5.44 mg/dl,Mg 10.23± 2.06 mg/dl and P 53.40± 6.94. In this control group the absorption (intake-faeces) was: Ca 89.98 ± 18.73 mg/kg/day; Mg 14.19±2.08 mg/kg/day and P 88.59± ± 13.96 mg/kg/day. Serum calcium, magnesium,phosphate, lipids,cholesterol and triglycerides were normal on all ocassions. In supplemented group the absorption in each baby was: Ca 202.17; 232.29 and 216.63 mg/kg/day; Mg 20.59; 19.77 and 17.99 mg/kg/day and P 80.05; 100.40 and 83.19 mg/kg/day.Calcemia increases in two cases (11mg/dl) on the 4th day, but no hypo or hypermagnesemia appeared. As previous experiences has suggested the supplementation considerabily increases the absorption of divalent cations.
