OK, So lets see the studies on this. Add an acetyl group to L-Carnitine and I'm not impressed. Acetyl-CoA is nothing more than a 2 carbon molecule produced by normal energy metabolism constantly - supplementing to get it would be like supplementing with saturated fats. Silly.
L-Carnitine is part of L-Carnitine Acyl Transferase, a molecule that is required to bring fatty acids into the mitochondria for oxidation. The lit. I've read on carnitine is not impressive (except in horses).
MacG, can ya give the URL for the above?...
Nothing irks me more than presenting something as if there is scientific data to support your (not meaning you at all MacG) contentions without providing the scientific proof. This is how supplelment manufacturers hock their shit all the time...
I feel better now. LOL
