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.” Emphasis on the tart. The flavor is okay. I enjoyed it more after trying it several times. Also of note, the powder does not dissolve entirely in water. I found this in others’ reviews, so I don’t think it’s just my shaking. (Maybe I have a weak arm?) There are always some particles at the bottom of my bottle or cup, but they taste fine if I try them with my fingertip.
Glutathione itself is an antioxidant known for providing energy and focus and boosting the immune system. GRB specifically includes L-Glutamine, which has been shown to minimize breakdown of muscle while working out. In addition, GRB has theobromine and N-acetyl cysteine (more words I can't pronounce). The former is known for supporting athletic endurance and supplying a stimulating effect without caffeine (so that is what I want more of), and the latter increases exercise capacity and reduces fatigue.
I took this drink in several settings. The first time I had it after drinking a whole Trenta coffee, so I really couldn’t distinguish GRB’s effect from Starbuck’s. But I’ve had it a couple of times solo, and there definitely is a mental boost and alertness that accompany drinking GRB. I won’t tell you the stimulation lasts for hours, but it perks you up enough to feel motivated, maybe enough to even open your computer and write a blog post. (I’m not talking about myself. Never!) There may also be a placebo effect. I do feel stronger and ready to get ‘em (whoever them are) when I’m at the gym after having GRB. And I'm feeling pretty optimistic and content right now after downing a GRB drink. Maybe I'll have another.
I like that the packets are portable. You can easily throw these in your suitcase, pocket, or bag and just grab a water bottle wherever. The price breakdown per pixie stick is also comparable to a Gatorade. Rob Keller MD’s website sells the box of 15 for $29.95, so $2/pop. (Amazon seems to be more expensive, so beware.) I’ll continue using these, maybe as a supplement when I begin caffeine withdrawals soon. (If I begin caffeine withdrawals.)
So next time you need an pick-me-up (that’s not coffee), grab a GRB stick!
