During a hard day on the bike, your body loses fluids and electrolytes as you sweat. Electrolytes help the body absorb the water and fire your muscles. Nuun developed an electrolyte tablet that you can dissolve in water. The tablet comes in twelve flavors and does not contain any sugar. Nuun Active Hydration is perhaps best known for its slightly carbonated, fizzy texture. We've also found it to be a pretty effective hangover cure.
Nuun now has a new trick up its sleeve. Nuun Plus comes in the same tablet form as Active Hydration, but this time, it contains dextrose and sucrose. Each tablet includes 25 calories of carbohydrate and you can use up to four at once. The goal of Nuun Plus is to offer a customizable nutrition option. Maybe you're planning an all-day adventure or you have a hummingbird quick metabolism — then you might want to add four tablets to your bottle. If you just need a little extra energy, add one or two.
Because Nuun Plus is designed to be used together with Nuun Active Hydration, it has no flavor. The sucrose and dextrose are designed to move through your body's multiple metabolic pathways to speed absorption. Nuun's compact tube packaging makes for a portable nutrition and hydration option. Throw a couple tubes in your bag and you're ready for anything. Nuun Plus will be sold in tubes of 12 tablets. [$7; nuun.com]
