Nuun Sport 8-Pack + Caffeine

The 80 servings across the 8 tubes is perfect for packing into my gym bag for the week. The mild fizz is a nice change from flat water, and I've noticed a difference in how refreshed I feel mid-workout.

These dissolve crazy fast in my bottle, no chalky bits stuck at the bottom like some other tabs I've tried. I keep a tube in my gym bag for when I need a little pick-me-up mid-workout, and the caffeine boost is subtle but just enough.

The 80 servings per box is the real value here—I've been using these for my long bike rides and the electrolyte blend actually keeps me going without that heavy stomach feeling. The caffeine tubes are perfect for mornings when I need a little extra push before hitting the trail.
