I’m new here, coworker of mine loves this site. Anyway, i tried searching the forums for this and didnt see anything directly relevant, so if this has been asked and answered before I apologize.
Found this tonight:
Not amazingly comforting considering ive been taking EE-Cr, l-glutamine, and, heres the kicker… met-rx’s amped. Amped of course contains more caffeine than a Starbucks warehouse.
So now my question… what do you guys know of caffeine screwing up the intake of suppliments in general? What about suppliments other than creatine? I’ve read l-glutamine uses the same transports as creatine, so it stands to reason it’d be effected as well right?
Does the form (ethyl ester, micronized, etc) play a role at all here?
There was a study done in 1998 by Vanakoski et al that showed that caffeine does not affect the uptake of Creatine into the muscle.
The problem with Creatine is getting it to your muscle before it converts to Creatinine, which cannot be used by the muscle cells. This begins the moment Creatine Monohydrate is added to a liquid, and it is this conversion that causes a lot of people to experience bloating and diarrhoea when using Creatine. And the form does not help either. Creatine EE, Creatine Titrate, Creatine Malate, Creatine Alpha-Ketoglutarate are all useless as the actual process of making them pretty much converts them to Creatinine. Micronized just describes the milling process that makes the Creatine into a fine powder, so that plays no role.
I hope this has helped,
I could have this completely wrong since I’m going from memory, but I thought I remembered from something I read (awhile back) that the caffeine-creatine “thing” wasn’t an issue of uptake into the cell, but of caffeine possibly interfering with the reaction in which creatine gives up a phosphate in order for ADP to be converted back to ATP.
I’ll have to look for the site where I read that (or something like that, since I can’t remember the specific details). I don’t even remember if it referenced a study. Coulda been someone just talkin’ out their ass. Possibly like I may be doing.
