A crisp, great-tasting lift that feels intentional. Built for the moments you want energy, not jitters.

One of the main reasons I love O2 is the non-carbonated, clean caffeine, and great taste. The new version is ok, but I'm not a fan of the carbonation. I like the caffeinated boost before a workout from the previous version. Having bubbles in my belly during my workouts from the new carbonated version isn't great.

I swapped to this flavor because they stopped making the Orange Mango flavor without caffeine. This energy version tastes fine, but I prefer the discontinued drink for both flavor and lack of carbonation.

Liked the old product
Not a fan of carbonated drinks in the morning and the taste was not nearly as good as the original orange mango. After 7 plus years as a subscriber, had to cancel as the original product is no longer available
