I got a advertisment/flyer through the post from a supplement company the other day
I glanced through the blurb before binning it and saw that they made the claim that training and other exercise "uses up" lots of L Carnitine so supplementation was important. A couch potato, they said, needed no extra L Carnitine but training hard does
Any comments on this claim? I've never read any evidence for L Carnitine being like this.
