I hope I did the right thing by removing the poll you had set up. This doesn't seem like a question for a poll, but if I'm wrong I can put it back (maybe).

 

Iirc, K1 and K2 have fundamentally different sources. If you're at the initial stages of research, perhaps that would help.

I'm tagging @Doogles31731 because he wrote a book on vitamin K.

 

My only hint: the difference between K1 and K2 is somewhat like the difference between plant based omega 3 PUFA and the DHA form of omega 3 found in fish and other animal sources.  Research what happens when gut microbiota process the plant based K1. 

Vitamin K was originally defined as anything that would treat vitamin K deficiency (which causes problems with blood clotting).
It was later found that there are a number of chemicals that will do that so they are all referred to as "vitamin K" but given numbers to distinguish them
