The primary function of vitamin K is to act as a coenzyme for proteins that regulate blood clotting. Vitamin K has an adequate intake (AI) of 120 mcg for adult males and 90 mcg for adult females. Fortunately, most Americans consume an adequate amount of vitamin K from food. Newborns are the greatest population at risk for vitamin K deficiency and the bleeding (VKDB) that goes along with it. To avoid this complication of early life malabsorption, it is important for babies to receive a vitamin K shot at birth.
Other malabsorption conditions for vitamin K are cystic fibrosis, celiac disease, short bowel syndrome, other gastrointestinal disorders. Studies have shown a link between high vitamin K intake and lower risk of hip fractures, higher bone mineral density, and possibly a lower risk of coronary heart disease mortality.
