I have been waiting for a study like this to come out.
A research group in Tel Aviv has finished one of the most comprehensive studies of Vitamin E supplementation, which analyzed all other prominent studies on the subject and considered data from over 300,000 people in the US, Europe and Isreal.
They found that, on average, popping Vitamin E pills may negatively impact quality of life.
From the press release: "To explain the meaning of this parameter," says Dr. Pinchuk, "consider a participant who was healthy during the first 10 out of 20 years of the study, but then suffered a stroke and became dependent on others throughout the following 10 years. The QALY [quality-adjusted-life-years] during the first 10 years of healthy life is 10, but after the stroke the quality of life is only half of what this person had before. Therefore, the second decade is considered the equivalent of merely 5 years of healthy life and in sum a person's QALY is 15... On average, the quality-adjusted longevity is lower for vitamin-treated people. This says something significant."
Other studies have shown vitamins to be ineffective, or to cause birth defects or asthma, or to put undue strain on the kidneys. I think there will be more studies like this one. The body is not meant to be hit with vitamins, minerals or fatty acids in the concentrated form they are found in pills. Why pop capsules when you are better off with something yummy, like a spinach frittata, spaghetti marinara or toast smeared with nut butter.
