aspirin will thin your blood.. probaly a good preventative measure..
also Vitamin E is very good.. but make sure its only Unique E from the AC Grace company.. and take 400IUs per every 35-40lbs of body weight all at once.. (6 maximum capsules).. Vitamin E does wonders for circulatory issues... but go to your doctor and make sure youre in the safe zone because its better IMO not to be taking aspirin AND vitamin E simultaneously
