The properties of Vitamin K1
Vitamin K1 helps your body absorb the vitamin D (it helps keep your bones strong and healthy).
Vitamin K is naturally found in human milk. Maternal vitamin K supplementation increases milk vitamin K levels and can improve vitamin K status in breastfed infants who receive intramuscular vitamin K shortly after birth. Maternal vitamin K supplementation should not be considered a substitute for vitamin K prophylaxis administered directly to the newborn. Late vitamin K-deficiency bleeding, including intracranial hemorrhage, can occur from 2 to 12 weeks and up to 6 months postpartum in breastfed infants.

For the treatment of haemorrhagic conditions in infants, antidote for coumarin anticoagulants in hypoprothrombinaemia. Vitamin K is an essential cofactor for the gamma-carboxylase enzymes which catalyze the posttranslational gamma-carboxylation of glutamic acid residues in inactive hepatic precursors of coagulation factors II (prothrombin), VII, IX and X. Gamma-carboxylation converts these inactive precursors into active coagulation factors which are secreted by hepatocytes into the blood. Supplementing with Phylloquinone results in a relief of vitamin K deficiency symptoms which include easy bruisability, epistaxis, gastrointestinal bleeding, menorrhagia and hematuria.
