Thanks, Laura, In fact, a few years ago, before I knew anything about mercury in fillings or was taking vit. E, etc. I gave a blood donation for platelets. They later phoned me to inform me that I had a somewhat low platelet count (not too low to donate), but the platelets I had were clumped together. So, if these vitamins do not thin the blood too much, it is probably a good thing to be taking them, for more reasons than one.
