“My wife takes it on recommendation from a friend who says we need it if taking vitamin D3 to help the D3 do the job it is supposed to do. I have had it for several years and when my vitamin D was checked recently, it was 75 nmolL or above Optimum -Her level was 77. I don't think that would have been without the K2 and the way her health has been in the last few months.”
