Right. I've seen anecdotes of people (pretty much all men, as I remember) who've gone from a high calcium score to a lower one after a year of taking K2 (no mention of which sidechain). But until I see a clinical study, color me unconvinced.
It does somewhat make sense as K2 might help to progressively dissolve a calcium deposit - I've also seen anecdata that it works for removing calcium deposits from joints, where there is no turbulence - not much fluid exchange at all.
Also: apologies for not marking that response as in-progress. In order to insert links, I have to save the response, then go in via stories/responses/edit to get to the main editor (response editor is... pretty bad - depending on the day, italics/bold/spellcheck nonfunctional)
