Can you drink apple juice and take warfarin?

However, excessive consumption should be avoided, as apple juice contains vitamin K, which can interfere with the effectiveness of warfarin.

Warfarin is a medication that is used to prevent blood clots.

It works by interfering with the body's ability to form clots. Vitamin K is a nutrient that is necessary for the body to produce clotting factors. Consuming large amounts of vitamin K can make it more difficult for warfarin to work effectively, increasing your risk of blood clots.

One cup (240 ml) of apple juice provides around 47 mcg of vitamin K.

The recommended daily intake of vitamin K is 120 mcg for men and 90 mcg for women.

Therefore, it is unlikely that moderate consumption of apple juice (such as one cup per day) will significantly interfere with the effectiveness of warfarin. However, individuals who are taking warfarin should always talk to their doctor or a qualified healthcare professional before making significant changes to their diet.
