Improve vitamin K status

What this outcome means

Vitamin K status reflects whether your body holds enough of this vitamin to support the clotting and tissue processes that depend on it. On DoseRank it maps to a defined health outcome built from human studies on plasma vitamin K levels, undercarboxylated protein markers, and clotting-related measures – data sourced from open sources and specialized resources. DoseRank is not medical advice.
