@hwisdom said in vitamin K2 MK7 instead of MK4 for ulcers from aspirin, does it really matter that much:
my actual question was about the efficasy of mk7 and if its good enough to activate the clotting factors that are shut down by aspirin
Vitamin K and Clotting
Vitamin K could perhaps be considered as a facilitator
High levels of vitamin K ensure that the circulation system can function effectively, as K activates anti-coagulation proteins. Vitamin K does not trigger clotting, it only ensures that the clotting and anti-clotting systems work effectively.
Both of these systems depend on sufficient amounts of vitamin K being available. Vitamin K does not initiate the formation of a blood clot, nor does it resolve or dissolve a clot. However, vitamin K does improve the functioning of both these systems. The key role of vitamin K is to make sure these systems work effectively.
The risk of unnecessary clots is increased when there are low amounts of vitamin K. A right amount Vitamin K is required to enhance balance between clotting and clotting factors (aka a balance between pro-coagulant (clot-forming) and anticoagulant (clot-inhibiting). A deficiency leads to a shortage of these factors, resulting in an increased risk of bleeding and bruising from minor injuries.
