    We don’t have official recommendations on how much vitamin K adults should take. The National Academy of Sciences has good recommendations. For an adult woman, they recommend 90 mcg/day and for an adult man, they recommend 120 mcg/day.

    As we cannot offer medical advice, I cannot tell you take these recommended amounts. Especially since you have a previous medical condition, it would be best to continue to work with your doctor to find a daily amount of vitamin K2 that is safe and effective.
