IMHO, this variance (
noted below with the 2 polar opposite forms) makes sense for a certain population who's gastric chemistry is
slightly off (lacking acidity or having too much of it).
I guess a "crude" strategy would be this....
If stomach issues
ARE typical for you, are they usually amerliorated with concomitant use of an anti-acid (buffered/alkaline) OR with more acid (HCL)? Perhaps apply the same logic here with your creatine use (
use the same form that alleviates your stomach issues with food).
If stomach issues are
NOT common and you're one that can typically eat anything without accompanying distress, then your issue is probably NOT related to the acidity or alkalinity of the creatine FORM and moreso with the creatine itself.
Make sense? This theory may be full of holes, but it's worked for me.
Only one Ive had 100% succes with is Kre-Alkalyn (buffered Creatine formula) by NOW Brand
my vote goes to creatine hcl, studies of seen on solubility lead me to believe that absorption would be better and thus less gi issues. Just a thought
