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.
I actually just want to double check please. Isn’t the DV for vitamin K 80 mcg, will less than 10000iu vit d cause any problems if you don’t get enough vitamin k,I get 100mcg in a supplement.thank you.
