Refreshers have dominated summer beverage menus, from Starbucks' colorful Refresher lineup to viral drinks at independent cafes. But dietitians warn that these icy concoctions may deliver less hydration than their marketing suggests.
Refreshers typically combine fruit juice, coffee, or tea with sweeteners and often contain electrolyte additions like coconut water. Starbucks' Mango Dragonfruit Refresher and Strawberry Acai Refresher, the chain's fastest-growing beverage category, exemplify the trend. Yet the hydration benefit depends entirely on what's actually in the glass.
The problem starts with sugar content. A grande Strawberry Acai Refresher contains 45 grams of sugar—nearly the daily recommended limit for women in a single drink. That volume of sugar actually increases the body's fluid requirements rather than satisfying them. Dietitians explain that high-sugar beverages force the kidneys to work harder, drawing water from cells to dilute the sugar in the bloodstream. The net result: you feel thirstier.
Electrolytes like sodium and potassium matter for hydration, but refreshers rarely contain meaningful amounts. Most lack the electrolyte balance found in actual sports drinks or, more efficiently, plain water. Coffee-based refreshers add caffeine, a mild diuretic that increases urine production.
