Drew asked:


I’ve recently started taking L-Glutamine and Branched Chain Amino Acids for weight lifting and working out. I’ll also be getting into carnitine when I start cutting down.

My question is, are there any long term side effects for these three supplements? And will there be defficiencies when I decide to stop supplementing (as the body will no longer produce, because it’s been supplemented for so long)? And this brings me to another question (I’ve asked in diet/fitness category also), do you need to cycle any of these supplements?

And please, I would like to know facts and not just opinions. Thanks in advance!
