The active girl’s most coveted accessory these days isn’t a new clutch or electronic organizer—it’s water. Glacéau water, that is. A cell-reviving, thirst-quenching beverage, the brand’s Smartwater enhances vapor-distilled H2O with electrolytes (much like a standard sports drink, but without the unwanted sugar and calories). The electrolytes enable water to hydrate the body’s cells faster and more efficiently—so that all of us, even nonathletes, can look and feel our best. Those seeking to boost their liquid intake with added benefits should check out Glacéau’s Vitaminwater (shown), a low-sugar, nutrient-rich elixir that comes in various formulas. Try the Multi-V version for a daily dose of B vitamins, calcium, and antioxidants, or the vitamin C-and-zinc-fortified Defense to ward off winter colds.
