Vitamin K deficiency Gla-residues are inadequately formed and the Gla-proteins are insufficiently active. Menaquinone (vitamin K), but not phylloquinone (vitamin K), intake is associated with reduced risk of CHD mortality, all-cause mortality and severe aortic calcification. The prevalence of vitamin K deficiency varies by geographic region. For infants in the United States, vitamin K deficiency without bleeding may occur in as many as 50% of infants younger than 5 days old, with the classic hemorrhagic disease occurring in 0.25-1.7% of infants. Therefore, the Committee on Nutrition of the American Academy of Pediatrics recommends that 0.5 to 1.0 mg Vitamin K be administered to
