    At http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/ there is a good section about Vitamin K. There you will find the RDA. There are no studies at this time that prove you need more than the RDA. If something changes it will get reflected there. Vitamin K also stores in fat so do not get carried away with too much in supplement form.

    The National Academy of Sciences says an Adult male needs 120mcg a day of Vitamin K. If you add up what is in your diet and are getting enough then do not supplement. If there is not enough in your diet then you should supplement.
    The point is whether you are taking 2000iu or 5000iu or 10,000iu, just make sure you are getting the 120mcg a day. Vitamin D does not increase the requirements, it needs Vitamin K as a cofactor.
