Vitamin K Source: Leafy Greens
Leafy greens such as kale, spinach, Swiss chard and collard greens are very high in Vitamin K. Just 1/2 cup of these greens, cooked, can contain more than 500% of the recommended daily amount of vitamin K.
Important health note: Misuse of vitamin K in supplement form can produce toxicity, and if you are taking the blood thinning drug Coumidin or any other anticoagulant drugs please check with your doctor before increasing or decreasing your vitamin K intake. When obtained from food sources, 500% of the DV may sound like a lot, but vitamin K consumed through food rarely produces toxicity.
