DHEA Strikes Out on Alzheimer's
DHEA is touted as an anti-aging supplement on the basis of a number of studies. (The Life Extension Foundation is a good place to find out more about this particular supplement. Do bear in mind that they are trying to sell to you, however). This story in ScienceBlog details a new study that seems to show DHEA to be ineffective in preventing Alzheimer's. More research needed here, I think.
