yes, there is a complex of minerals and vitamins that work together. The push has been for more calcium to have good bones but whole picture has not been explained, supported or recommended.

K2 has virtually disappeared from our American diet. As a kid I ate pickled fish, being a good Swede, but even that is gone--epecialy as it is loaded with sugar. Have been buying raw sauer kraut for now as it is much cheaper than gouda and brie. Loooking to make my own pickles this summer ....... even cheaper.

Looking at this product to be sure I get the K2 microbes.
