Vitamin K is an essential vitamin required for protein modification and blood clotting.
Recent studies suggest that vitamin K may play a role in treating osteoporosis and Alzheimer's and that consuming increased levels of vitamin K can help protect against cancer and heart disease.
Unless you are taking medication to prevent blood clots, like Warfarin or Coumadin, there is no known risk of vitamin K toxicity, and no reason not to eat a lot of it. If you are on Warfarin (Coumadin), please check the article on low vitamin K foods for a Warfarin diet.
Foods high in vitamin K include leafy green vegetables (cooked and raw), broccoli, brussels sprouts, cabbage, pickled cucumber, asparagus, kiwifruit, okra, green beans, and salad greens like lettuce. The current daily value for Vitamin K is 120 micrograms (μg).
