I would like to know if anyone else has experience breast tenderness when taking MK- 7. I have been taking it every other day and still get the reaction. I know it is from the MK-7 since when I do not take it my breasts are not tender. I am in my sixities. I also wanted to know if there was another MK-7 that was not from soy that would be just as good since I feel it is the soy that is the problem.
