It was recommended, that my Hubby take 1 325mg. Bayer aspirin, a day. He has faithfully, for 20 years. He has heart disease and one heart attack, plus, 11 coronary stents. The aspirin helps keep his blood thinner, which is very important when having stents, in the heart. He was never ordered to take the baby aspirin, but, the whole ones. Now, I can get him the right aspirin, Bayer's, at an excellent price.
