Hello @oubobcat,

Welcome to Connect. Vitamin K, does help the body make blood clotting proteins. Both K1 (green leafy veg.) and K2 (dairy, fermented foods) have some antioxidant properties, but clinical trials have not shown any evidence that vitamin K supplements can slow calcium deposits in artery walls.

I’d encourage you to view this discussion, https://connect.mayoclinic.org/discussion/im-having-multiple-odd-episodes-that-are-keeping-me-undiagnosed-help/ where @jenniferhunter @johnwes5819 @slynnb @becsbuddy @predictable and others are talking about vitamins K and D and other supplements.

I’ve also copied Mentor @predictable’s caution about vitamin K, for your reference: "Please be careful about taking Vitamin K! Discuss that with your medical doctor before following any nonmedical advice. Vitamin K is an antidote for Warfarin (Coumadin), an anticoagulant that is widely used to reduce chances of blood clots forming within the heart and other parts of the circulatory system. Those clots can really damage the brain, the heart, the kidneys, and other vital organs by blocking the flow of oxygen-rich blood to those organs.”

Here’s some more information from Mayo Clinic: https://www.mayoclinic.org/diseases-conditions/high-blood-cholesterol/diagnosis-treatment/drc-20350806

I’m tagging @mcphee @gailfaith @drankin @ca426 @luckyg @botexas @mcristodero @thankful who’ve shared some valuable insights about vitamins in these discussions on Connect:

@oubobcat, have you asked your doctor about including this supplement?
