Why is the % Daily Value for Vitamin K in DAKE so high? Is it safe?Updated 19 days ago

The percent daily value figure looks alarming at first glance, but context matters. The DV for Vitamin K was established primarily around K1's role in blood coagulation — it reflects the minimum needed to maintain normal clotting, not an optimal intake for bone and cardiovascular health. The research supporting MK-4's benefits in bone density and arterial calcification uses doses well above the DV, which is why the percentage looks the way it does. 

Vitamin K does not have an established tolerable upper limit in healthy adults — unlike Vitamins A and D, excess K is not associated with toxicity at supplemental doses. The one practical consideration is for anyone taking anticoagulant medications like warfarin, where consistent Vitamin K intake matters for dose management. If that applies to you, consult your prescribing physician before starting.
