My doctor told me to take baby aspirin and Centrum Silver multivitamins. I don't take the aspirin because, as a young and healthy person, I personally don't feel that the marginal benefits from taking daily aspirin is worth the risks. But I do take the vitamins. They're the old people kind because they have lots of folic acid (good for heart health) and no iron. But really, you should ask your doctor what they recommend. They know your health history and everything better than any of us here do, and can hopefully give you a good idea of what sorts of things, if any, would be good for you to take.
