Wow, sorry to learn that. I'm happy your doctor caught it.

On a similar note, does anyone think that supplementing Vitamin K2 could work as a preventative measure for blood clots?

It may not help if you are currently taking blood thinners as in your case Krystal, I always see warnings on K2 supplements not to take it if you are already taking blood thinners.

We do hope for good news,

Linus Pauling Institute Recommendation

It is not clear whether the AI for vitamin K is enough to optimize the gamma-carboxylation of vitamin K-dependent proteins in bone (see Osteoporosis). To consume the amount of vitamin K associated with a decreased risk of hip fracture in the Framingham Heart Study (about 250 mcg/day) (44), an individual would need to eat a little more than ½ cup of chopped broccoli or a large salad of mixed greens every day. Though the dietary intake of vitamin K required for optimal function of all vitamin K-dependent proteins is not yet known, the Linus Pauling Institute recommends taking a multivitamin/mineral supplement and eating at least one cup of dark green leafy vegetables daily. Replacing dietary saturated fats like butter and cheese with monounsaturated fats found in olive oil and canola oil will increase dietary vitamin K intake and may decrease the risk of cardiovascular disease.
