General description

Vitamin K1, also known as phylloquinone, consists of naphthalenoid and phytyl groups. Phylloquinone is present abundantly in photosynthetic plants and is a major dietary source. It is a fat-soluble vitamin.

Application

<ul>
<li><strong>Nutritional strategies for musculoskeletal health:</strong> Nutritional strategies, including Vitamin K1, optimize musculoskeletal health for fall and fracture prevention beyond traditional nutrients like calcium and vitamin D (Webster et al., 2023 doi:10.1016/j.bonr.2023.101684).</li>
<li><strong>Role in coagulation and bone health:</strong> A comprehensive review highlights Vitamin K1′s role in reducing cardiovascular risks and details its biochemical interactions affecting coagulation and bone health (Zhao et al., 2024 doi:10.1017/jns.2023.106).</li>
</ul>

Biochem/physiol Actions

Vitamin K1 (Phylloquinone) is a lipid soluble polycyclic aromatic ketone used as a cofactor in the formation of coagulation factors II (prothrombin), VII, IX and X; anticoagulant factors protein C and S and as a cell signaling factor.
Vitamin K1 plays a role as a cofactor in the synthesis of γ- carboxy glutamate (Gla), formation of coagulation factors II (prothrombin), VII, IX and X.

Packaging

Vitamin K functions in animal cells as the cofactor of the enzyme vitamin K-dependent carboxylase which catalyzes the post-translational formation of gamma-carboxyglutamyl (Gla) residues in specific vitamin K-dependent proteins. These proteins include four blood coagulation factors (prothrombin and Factors VII
