GU Hydration Drink Tablets are a clean, low-fuss way to keep your electrolyte levels in check on the bike. Drop one into your water bottle and you get a lightly flavored drink that delivers sodium and other key electrolytes — the minerals that help your body actually retain and use the fluid you're taking in, not just pass it through. At only 10 calories per serving, they won't interfere with your nutrition strategy, whether you're already running gels or a recovery mix. The tube format is pocket-sized and spill-proof — easy to stash in a jersey pocket or kit bag for long rides, hot-weather training, or race day. Available in Lemon Lime, Orange, Strawberry Lemonade, and Tri-Berry.
