And form one decade ago: surprisngly high recommended doses (several thousand IEs) but then also coupled with warnings against hypercalcemia and
hypercalciuria.

That data maybe today is considered a bit dated.
I say once again: take Vit K2 if you tak ehigher doises, say more than 2000 IE (just my laymen guess). From levels of lets just say 10 thousand on and over long time, not just to fuill up your reserves for a week and then reducing again, have your blood serum levels monitored. I would not see the need to go this high and keep that dose for all time to come. I filled up my reserve sinc eI strongly assume I was deficitary, and then halved, and now halve again.
