If you’ve noticed, I’ve taken to reviewing sports products (WIN Detergent, Fuel100 Electro-Bites, and c2 running gear), and today is no exception. I got to try Rob Keller MD’s Glutathione Rapid Boost, otherwise called GRB, which is what I’ll call it because I’m not sure how to pronounce “glutathione.” I should probably learn how to, because it seems like it might be on the up-and-coming, just like quinoa, pomegranate seeds, and other “super foods” featured in listicles I find on Twitter. What most excited me about GRB is, this sports energy drink is caffeine-free. I’m always looking for a boost without caffeine, as my last blog post hints.

GRB comes in a box of 15 “pixie sticks,” which you break open and add to 8 to 12 oz. water and enjoy. (I did more water than that because I am not good at measuring and thought it tasted fine. Go big, or go GRB!) The only flavor currently offered is “Citrus-Berry,” which is more accurately “Sweet Tart.”
