I was using Now MK7 with MenaQ7. I recently learned there fore 4 versions of MenaQ7. Some of them are from natto. I see other brands that say from natto. Is this significant?

I think MK7 is all from fermentation. I am highly suspicious of MK7 and never use it. It is toxic in higher doses, stays around for days, indicating that the body has difficulty dealing with it. Go for MK4, which is physiologic. MK7 would never have been promoted if not for the Japanese corporatocracy promoting it due to its coming from natto.
