I am a 48 year year old female with low blood preasure, that has had Mitral valve repair on Sept 17th 2012, all was going well (I thought) when on Oct 4th, 2012, I had a TIA (mini stroke) and Pericardial Effusionon (fluid around the heart). After a week back in the hospital, I was discharged on Warfarin. So I have joined Spark people to track my sodium intake and cardio excersise. I would like to track my Vitamin K intake, but can't find it as an option for tracking. Any help would be appreciated.
