Thank you Asklipia! Actually I spent the weekend reading bits of the MK4/MK7 thread too. Your experiences are super interesting. I am going to order some MK4 as well, though it is exciting that the starch helps the body to produce/convert K2. The EM is supposedly extremely popular in Japan. They put it in lots of different products. I love that I can clean my house with something that I can also drink for my gut.
