Vitamin K1 (Phylloquinone) Unit Converter
Vitamin K1 (Phylloquinone) is the primary dietary form of Vitamin K, essential for the synthesis of coagulation factors II, VII, IX, and X. It is found in green leafy vegetables.
Monitoring Vitamin K status can be important for patients with bleeding disorders, malabsorption, or those on anticoagulant therapy like Warfarin. This converter facilitates switching between standard mass units (ng/mL, μg/L) and the international SI molar unit (nmol/L).
Mass Units
StandardNanograms per milliliter (Numerically equivalent to μg/L).
SI Units / Molar
Nanomoles per liter (International Standard).
Clinical Context
Reference Ranges (Plasma/Serum):
• Fasting Adult: 0.2 – 3.2 ng/mL (0.44 – 7.1 nmol/L).
Note: Ranges depend heavily on recent dietary intake.
Clinical Significance:
• Deficiency: Leads to impaired clotting (elevated PT/INR) and increased risk of bleeding.
• Warfarin Interaction: Warfarin works by antagonizing Vitamin K. High dietary intake of K1 can reduce Warfarin efficacy.
Conversion Logic:
Molecular Weight of Phylloquinone: ~450.70 g/mol.
1 ng/mL ≈ 2.22 nmol/L.
1 nmol/L ≈ 0.45 ng/mL.
