Fantastic Energy
I absolutely love this variety pack. For starters, the flavor isn't overbearing. It provides the perfect hint of mango, berry, lime, mint, etc.
Second, it's an awesome source of energy. I've taken several of them on an empty stomach (as it advises), and have had fulfilling workouts as a result. An added benefit of these is that you don't feel the caffeine jitters like you do in most energy drinks and pre-workout supplements.
Lastly, I'm a big fan of the low calorie count. It's a great alternative as opposed to Gatorade/Powerade and is also gluten free.
I'm excited to try additional flavors!
