Article on this in NYT science section today (Tuesday) as well.
My university was recently recruiting "healthy, active, but non-elite" test subjects for research on muscle fatigue. I was intrigued but didn't respond partly out of laziness and partly out of a requirement that participants must "not be currently using any supplements" and it seemed like too much work to find out if the multivitamin, flaxseed, calcium, aspirin regimen I'm on counted as banned supplements. (Seriously, are there any women of childbearing age who don't take calcium supplements? I don't have any intention of having children, I just buy the hype about building strong bones, esp. because my birth control can have negative impact on bone density).
I should see if they're still recruiting, I could get a free fitness assessment out of it.
