Too much vitamin E?

Since being diagnosed in April I have been researching natural products such as vitamins and herbs to take to aid in my diabetes control. I found an article, then lost it that said that too much vitamin E can actually be dangerous to overweight diabetics. Here is the portion of the article that I saved. Has anyone else researched this? "There are many studies and investigations of vitamin E that are carried out around the world and it is very interesting that all of the trails and the investigations have come out differently. For instance, one trail that involved vitamin E glucose tolerance improvement in patients with diabetes showed that an intake of 585 international units daily of vitamin E lead to worse glucose tolerance in overweight people with diabetes. The reason for the different results in each study is unknown." "Anxiety does not empty tomorrow of its sorrows, but only empties today of its strength."

That's a single study that used very large doses of vitamin E. Many studies using lower doses (generally no more than 180 units/day) show improved glucose tolerance. Additionally, there are studies (although I haven't read them in detail) that show diabetics with heart disease are at increased risk for heart attack with very high doses of vitamin E. In other words, if you are going to take vitamin E, it might be wise to stick to the lower doses.

There is much literature lately that vitamin D is beneficial in both improving insulin resistance and decreasing the incidence of heart attacks in diabetics. Vitamin D deficiency is very common, especially in northern climes. For what it's worth (and individual experience is only worth so much), my endocrinologist recommended I take 1000 units of vitamin D a day a couple of months ago. My blood sugars have been running about 10-15 points lower, and I've had to cut back slightly on my medication.
