Hard to know for sure why that person had a stroke. It could be that there was some estrogenic activity from the natto, and that caused damage to vessels. Also, I thought MK4 was the preferred kind of K2 (though I've heard it's good to get some of all of them).Yes, I consume it via natto, which is fermented soy. I know it is recommended against. However many speculate that soy when fermented loses its estrogen properties. It is the food highest in vitamin K2 in the M7 format. I think it has about 1100% per 100 grams, if I remember correctly.
Useful to make sure calcium is put in the proper spots in the body. Interestingly in one of Ray's articles he speaks about calcium displacement being the primary negative effect of aging.
Difficult to find high sources of K2 in foods.
