A very sad story & my thoughts are with the girls family and friends. A young life taken so early.
Quite a sensationalist story on MSN today, which doesn't do much for the reputation of running...nevermind the many thousands who turn their life around & see massive health and emotional improvements through running.
My own personal view (and experiences) are that eating a balanced diet, drinking sufficient water and making homemade sports drinks (1/2 water, 1/2 juice and a small pinch of salt) are better than taking supplements in most cases... (obviously some conditions or nutritional deficiencies would benefit from supplements in addition to a balances diet)
I've run a few marathons & only ran to my potential in the marathon where I drank plain water, a few sips of homemade sports drink and ate 5 jelly babies (not in 1 go). Previously I'd suffered terribly with stomach problems when training/racing with gels and flat lucozade, even after trialling them in training and as a result DNF'd a few races.
Partly it is a marketing ploy....and partly it is the placebo effect, taking a supplement, believing it will help.
We are all different, so what works for one, won't neccessarily work for another. I've seen people gobble down snacks and biscuits 10 minutes before running a race..and running well! That would cripple my guts & I'd be unable to run for at least another 2 hours. I think that is the key factor - our bodies are all wired differently & we react to substances in different ways.
Sorry if I've gone off on a tangent here....haven't read the whole thread
