I've had to start hiding them

  • Familiarity: I've put it through the wringer

I've actually had to start hiding these from my roomates as they seem to always be empty. They are just a great way to get that extra boost of hydration you need after a day of being outside. The flavors are not overwhelmingly strong or sweet and I love the slight fizzyness it adds to your water. Grapefruit flavor is my favorite.

Like the flavor; dislike the fizz

    I tried this in Peach Tea because I really like the flavor, but dislike how chewy the Chomps are. Well, the flavor is still good, but I actually don't like the carbonation/fizziness/effervescence/what have you. I like the tube they come in. I dislike that the flavor was difficult to get out of my Camelbak podium bottle. It took a good 1-2 weeks including a good scrub down and several uses with plain water before the peach tea flavor disappeared completely from my bottle.


      Not meant to be a carbohydrate replacement. These are just to replenish electrolytes. Not ideal in every circumstance but when used properly, excellent. On a long ski day when I cary plenty of carb calories as solid food, a waterbottle with GU brew is perfect for keeping electrolytes up and preventing cramps. The small canister is good for bringing a couple tabs along on a big push. Give it a bit of time to dissolve.


        These are alright but they take a while to dissolve and the fizzing is a little annoying when drinking. They only provide electrolytes so that is a minus. Gatorade gives you carbohydrates as well so you are helping to replenish your energy stores. These will do the job but there are other options that are better in my opinion.
