How much Vitamin K is in soy milk?

I just read on your website that soybeans contain quite a lot of Vit. K. Does that mean that drinking soymilk is banned for a Coumadin patient? Considering dairy products don't agree with me, what would you recommend?

Dr. Gourmet Says...

Edamame (Soybeans)

There is a minimal amount of Vitamin K in soy milk. One cup contains about 7 micrograms (mcg) of Vitamin K. This is considered a low amount of Vitamin K and should be safe for those taking Coumadin (warfarin).

Dairy products in general are low in Vitamin K, but if you are lactose intolerant (as it sounds like you might be), there are resources for those who are lactose intolerant here at, including lactose-free recipes and other tips. As an alternative, many people find lactase enzyme products like Lactaid® to be helpful when they wish to consume dairy products containing lactose. You can also look for lactose-free milks in the dairy case of your supermarket.
