A fat-soluble vitamin critical for blood clotting and bone health in two distinct forms.
Vitamin K is a fat-soluble vitamin essential for blood clotting and bone metabolism, existing in two main dietary forms: K1 and K2.
Vitamin K encompasses two forms with different sources and functions: phylloquinone (K1) from plants and menaquinone (K2) from animal products and bacterial synthesis. Both forms are essential for activating clotting factors and proteins involved in bone mineralization and cardiovascular health. K1 is the primary dietary form, accounting for about 75% of dietary vitamin K, while K2 has longer tissue retention and may have more targeted effects on bone and vascular health. The body possesses regulatory mechanisms to maintain adequate clotting function, but K2 appears to offer additional benefits beyond basic coagulation. Some K2 is synthesized by gut bacteria, though this contribution varies among individuals based on microbiome composition and antibiotic use. Vitamin K deficiency is rare in healthy adults but can occur with malabsorption or certain medications.
Activates clotting factors for proper blood coagulation and regulates bone mineralization and vascular calcification.
Consume leafy greens daily to ensure adequate K1 intake (90-120 mcg). Include fermented foods like sauerkraut for K2 sources. Those taking anticoagulants should maintain consistent vitamin K intake and consult healthcare providers about dietary changes.
Vitamin K in its two forms ensures proper blood clotting and supports bone and cardiovascular health.
