Drinklits Lemon-Lime Daily Hydration Tablets (4) Tube Bundle

I dropped one tablet in my water bottle during a hike and it dissolved completely in under a minute with no gritty bits left at the bottom. The four-tube bundle means I've got one stashed in my gym bag, one at my desk, and two in the kitchen, so I actually remember to drink more water now.

The lemon-lime flavor is bright without that fake sweetener aftertaste, and one tablet in a cold glass of water perks me up way better than plain water on a sluggish afternoon. Four tubes means I've got one on my desk and one in the kitchen drawer so I don't forget to actually drink them.

I keep one of the tubes in my gym bag and drop a tablet in my water bottle after a run—it dissolves completely with no chalky bits left at the bottom. The four-tube bundle means I've got one at my desk, one in the car, and still haven't run out.
