Varicose veins are caused by a variety of factors: genetic inclination, standing occupations, obesity, or multiple pregnancies.
In a 2007 study from France’s University of Nantes, researchers examined 36 healthy male subjects and 50 male subjects with varicose veins. They found a link between varicosis and inactivity of a protein called matrix GLA protein (MGP). And because MGP is properly activated only when vitamin K levels are adequate, researchers theorize that sufficient intake of the vitamin may play a role in the prevention of varicose veins.
The importance of vitamin K intake for circulatory health is already well known. Dr. Tucker recommends 5 to 15 mg of vitamin K per day – considerably higher than the recommended daily allowance.
