Review: It works! - I like the sublingual K2 as I don't absorb well, so this is the best option for me. And I'm thankful that I found a good K2 mk4 that is sublingual from a reputable company. I've taken this supplement for awhile now and my calcium levels remain in the normal range while taking high dose D3 so I guess it's working!
Review: Fine quality. Just not for me. - I stopped taking it due to my CKD.
