title: [Fat-soluble vitamins in infants].
abstract: Vitamins are micronutrients not synthesised by the human body and should be provided by the nutrition. Liposoluble vitamins include vitamins A, E, D and K. Vitamins A and E are two potent antioxidant nutrients and play a significant role in immune function. Vitamin D plays a major role in intestinal calcium absorption and bone mineralization. Vitamin K intervenes in the synthesis of coagulation factors particularly in the prothrombin synthesis. Vitamin metabolism, placental transfer, vitamin status in newborns and infants are reported. Finally requirements of these vitamins are defined.
