Q: I am on warfarin (Coumadin) and a restricted fat and cholesterol diet. The legumes I use in my diet now cause me some digestive upset. I stopped using probiotics because they might change my warfarin level. I see Align advertised on your web page, would that be ok for me?
A: At this time there are no studies on using probiotics in those taking Coumadin (warfarin). This month in the Swedish journal Lakartidningen the question came up and they also reviewed the literature, finding no evidence for or against.
The issue is that such bacteria produce Vitamin K as part of their digestion process. As such, taking probiotics could, in theory, affect your INR by providing a greater population in your gut. Probiotics and Coumadin (warfarin)
