If you are focusing on K2 alone, natto is off scale. For zinc, by far the best common source is beef. It is not nearly as high as oysters, but when you compare daily eating of beef with once a year oyster platter, beef dominates. You want to make... (more)

You won't find it in traditional drug stores. Try The Vitamin Shoppe and maybe GNC or a "health food store". If they don't carry it they might be able to order for you.

I wonder if the K2 doesn't vary wildly with season. I know that the butter is different colours depending on the time of year. Hence why high vitamin butter oil is only from cows fed on summer pasture.
