So just in case anyone else got swept up in the belle de jour marketing of SIS…
Make sure your read all labels all the time. Sure they are safe sport certified. That is cool bro. Cool.
Anyway, I go to fill up my bottles with SIS Electrolyte mix the other day and I look up at the label and under “Other Ingredients” there it is, blinking like a neon sign: ASPARTAME.
Now maybe its my veganism. Maybe it is my understanding of what aspartame does in the human GI tract, but I was pretty pissed off 1. at SIS and 2. at myself for not reading up on it before i purchased it as part of an SIS training package.
Anyway, buyer / cyclists beware.
I still use their gels, but the idea that they would ADD aspartame to a performance product kinda puts me off of them.
