About Our Vitamin K1 Test

This test is used to determine Vitamin K1 (Phylloquinone) deficiencies. Vitamin K is a fat-soluble vitamin that is essential for blood clotting, and plays an important role in building bones and preventing heart disease. Having a deficiency of vitamin K can increase the risk of uncontrolled internal or external bleeding.

Deficient vitamin K levels can lead to:

  • Osteoporosis/Weak bones
  • Bleeding/Thin blood that doesn't clot well
  • Easily bruising and mucosal bleeding

Vitamin K deficiency can be more prevalent in people who:

  • Have a vitamin D deficiency
  • Have a fat malabsorption issue
  • Have celiac disease, Crohn's disease or cystic fibrosis
  • Use Coumadin anticoagulants, like Warfarin
  • Have alcoholism

Major vitamin K sources include:

  • Leafy green vegetables
