On a humid Tuesday morning in late May, boxes of single-serve electrolyte powders lined the counter at a Lower Manhattan juice bar. Managers say requests for hydration boosters have doubled since the start of spring. Some coffee shops now keep a jar of powder near the espresso machine, offering to stir it into iced drinks for commuters.
The powders promise rapid hydration, delivering sodium, potassium, and magnesium through fruit-flavored mixes. Registered dietitians point to their usefulness for customers who spend long hours outdoors or who come in after early-morning workouts. 'If you’re sweating on your walk to work, you lose more than just water,' said Michelle Lee, MS, RD, a dietitian consulting for several Midtown cafés. She cautions that not all powders are equal: some come with added sugars or artificial coloring.
Restaurant staff report that lemon, watermelon, and berry flavors see the most demand. Prices range from $2.50 to $4 for an add-on at most juice bars. At a Brooklyn diner on Sunday, a server said regulars have begun bringing their own packets, requesting them mixed into seltzer or iced tea.
The trend coincides with the city’s early summer heat and a shift in dining routines. After-school crowds and outdoor diners often seek lighter, refreshing options. Owners say they expect electrolyte offerings to remain on menus at least through the end of the season.
