title: Serum phylloquinone concentrations in a normal adult population.
abstract: The concentration of serum phylloquinone was assessed in a population of normal healthy Red Cross volunteer blood donors. The median value for 95 subjects was 1.1 ng/ml with a mean of 1.3 +/- 0.64 (SD) ng/ml. Sex, age, smoking habits, alcohol intake, and consumption of foods high in vitamin K were not found to influence serum phylloquinone concentrations.
