Here is an article from Tufts University I thought some of you may enjoy: http://enews.tufts.edu/stories/062303Folate.htm

Here are two points to keep in mind while reading this:
-this is still preliminary and complete conclusions haven't been established
-in one of the quotes from Morris in the article, she talks about fatigue and supplementation. Remember that the vitamin doesn't provide you with more energy. It is the treatment of a deficiency that does.
