@realitytest, just to make sure others who read your comment get another view of Vitamin K effects for those of us who take Coumadin (Warfarin) to prevent blood clots, my own experience doesn't require that I "greatly limit green vegetables and even red wine." I do take care to manage my intake of both green vegetables and red wine, but to the extent that I have them in my diet, my daily dose of Coumadin was adjusted upward a bit to overcome the Vitamin K antidote. It took a few months to identify a good mixture of Vitamin K foods and Coumadin, but having identified that mixture several years ago, I'm on a stable diet and medication now. As to the alternatives you are considering, I applaud your willingness and that of your medical team to try them. I have several friends who have to good effect, reducing arrhythmia and avoiding blood coagulation, and I've never heard them refer to their alternative as "inferior treatment." In fact, they think the latest anticoagulants are "inferior" for one reason or another. Martin
