    If you are taking a blood thinner or other heart medications, you should take vitamin E only after discussing it with your doctor, because vitamin E acts as a blood thinner and can adversely affect the overall effects of your medications. In some studies, vitamin E adversely affected some patients with a history of heart problems, while others showed the reverse -- that vitamin E actually has a protective effect on the heart.

    The recommended daily allowance for vitamin E is 15 - 30 mg. I believe that people without a history of heart problems, and who are not taking a statin or blood-thinning medication, may consider taking 400 IU of vitamin E per day, with a recommendation from their doctor.
