Plasma 25-hydroxy-cholecalciferol (25-OHD) was measured serially in two groups of preterm infants receiving either 400 IU or 1000 IU oral vitamin D3 daily. All the babies were able to absorb and hydroxylate vitamin D3 adequately by 36 weeks' gestational age. The higher daily supplement had no advantage over the lower dose.
对两组每日分别口服400国际单位或1000国际单位维生素D3的早产儿进行了连续血浆25-羟基胆钙化醇(25-OHD)测量。所有婴儿在孕36周时都能充分吸收和羟化维生素D3。较高的每日补充剂量与较低剂量相比并无优势。
