"Good for Postischemic Damage Control!"
I forget to mention it, but one reason that all of the research on the protection, by GLN and other supposed energy substrates, of the energy charge or adenylate charge during ischemia is "relevant" is that even high-intensity exercise, for example, can cause transient, very mild cerebral ischemia and is well-known to cause metabolic stress in the GI tract that essentially amounts to a low-level ischemia-reperfusion injury. The blood flow to the muscles can increase at the expense of the blood flow to other tissues, etc. But the point is that ischemia can be viewed as being an "everyday event." However, I recently saw some "sports supplement" that contained some questionable messages on the label, such as a "breezy" or even "happy"-looking blurb that read, "Good for preventing ATP depletion after cerebral ischemia!" There was a superscripted star by the "a" of ischemia, and the star referred the reader to the qualifying statement that read "(during your friendly-neighborhood exercise)". So at least there was that. But I still thought that that was in bad taste, just to a small extent. It's fine to face the facts, but...no, there was no such supplement.
