                        Please be advised that any multi-vitamin, such as Centrum, that lists vitamin K can counteract blood thinners.  I learned the hard way. A month after passing three clots into my lung from a leg thrombo-phlebitis, another episode occurred, which was attributed to the multi-vitamin Centrum, even though I took the blood thinner.
