I am currently taking Coumadin. So far doesn't seem to. Fish oil and aspirin do, though. Vitamin E may also, but there is much less information available, and if so it is minimal. Vitamin E General Info.
Vitamin E is an essential vitamin and appears to be included in the group called antioxidants.
Since there is currently no known toxicity to Vitamin E, it seems safe to take some until further definitive research is done. Therefore, I take supplements and eat as best as I can. Each ounce is about 14 grams of pre digested protein. The recommended daily dosage is about an ounce three times daily with water. Your body really doesn't care about the source of protein.
