@GRay said in mk4 dosing?:
isn't only the k1 that effect clotting?
K1 and K2MK7 too affect clotting.
For Chris Masterjohn, MK7 would even be better.

Excerpt 1:
There is reason to think MK-7 would be better at supporting blood clotting.
“MK-7 is not just three times better than K1 at reaching bone; it’s also five times better at supporting blood clotting (Schurgers, 2007). This may be because the greater fat-solubility of MK-7 makes it hold on more tightly to the membranes within liver cells, making it stay active in the liver much longer rather than being released and broken down (Shearer, 2008). The liver is where clotting proteins are made, so more extended activity in the liver would explain why MK-7 could better support blood clotting. If this is correct, other long-chain MKs such as MK-8 and MK-9 probably share this property as well.”
Additional comment:
The risk of improper clot formation is increased in cases of low vitamin K levels. Vitamin K (VK) does not cause or dissolve blood clots. However, VK enhances the function of both these systems. VK1 can therefore be seen as a facilitator: Procoagulant factors are VK-dependent.
Remind that platelet formation requires 10-12 days after taking aspirin, whatever the dose is (baby or adult caps).
