I read with interest and concluded that I am glad I have taken VitD for years and will continue to do so.
What did occur to me in the long conversation taking place, unless I missed it, there was no mention of taking K2 with VitD which is something that's always spoken off in the forum when the subject comes up. Again in conclusion, K2 is not essential to take alongside VitD otherwise we would be told to take it, surely!
