    Vitamin K. So we want N-A-K. K is quinone. It has a number of different names also. But most commonly in this form. And I really like to hearten the vitamin K. I could probably go on for a long time about it. Because it is produced by our gut flora. And I have learned a lot of different links as a neurobiologist between gut flora and brain connections and so on and so forth. So I think the gut flora are particularly important. We can consume vitamin K but also we rely on our bacterial inhabitance to produce the majority of our vitamin K. And vitamin K is in involved in clotting. You are probably familiar with that. In fact it's involved in multiple steps along the pathway for blood clotting. As with other blood soluble, I mean, other fat soluble vitamins, vitamin K really depends on adequate liver and pancreatic secretions in order to access the vitamin itself. So let's look at some of the issues with deficiency. Again the primary one that we'll consider is the clotting factors. You can see clearly that it is involved in multiple steps along the pathway for clotting including factor 2, factor 7, factor 9, 10. All of these require vitamin K as a cofactor. Now one drug I want to bring up that you probably are aware of that is involved in blood thinning. So it has actions opposite of vitamin K is coumadin. Sold under the name of warfarin and others.

    Warfarin and Vitamin K
    By Jake Bryan C. on 06. January 2017 for Vitamin K (Quinone) and Vitamin E (Tocopherols)

    From what I understand, we advise patients taking Coumdain to AVOID eating vitamin K rich foods because it will counteract the effect of the drug.
