  The vast majority of us have had to monitor our diet at some point in life. Whether you are attempting to control diabetes or lose weight: No matter what the circumstances, it’s not an easy thing to do. For those on anticoagulants like warfarin, it is important to control and maintain your dietary vitamin K intake. To be clear, it is not recommended to eliminate vitamin K from your diet but to manage your vitamin K. The optimum level of recommended consumption for adult men is not to go over 120 micrograms in their daily intake while women should not go over 90 micrograms.1

When it comes to choosing healthy foods, muesli is a great way to start your day. Created in a Swiss hospital by doctor Maximilian Bircher-Benner, muesli was a combination of oats and water, chopped apples, nuts, lemon juice and cream, topped with honey and touted for its health benefits.Muesli has not changed much since then, still containing a combination of oats, nuts, seeds, grains, dried fruits and spices.2 Perhaps the best part about muesli is that there is no set recipe and what’s included in the ingredients is all about the personal taste of the chef. Still, muesli is rich in fiber and protein and has plenty of vitamins, including vitamin K (2.5 micrograms per 1 cup).3 You can enjoy it as a cereal with any variety of milk or put it in yogurt. Neither of these is typically high in vitamin K content, but always check the nutrition label to be certain.

If you plan on making any changes to your diet, it should be first discussed with your doctor. Significant fluctuations in vitamin K intake can put you at higher risk for clot development or bleeding.3 Be proactive, making sure to take your medication and test your INR as directed your physician.
