Water alone won’t replace electrolytes that are lost through sweat, like potassium, sodium, and magnesium, which are essential for preventing muscle cramps during long runs or workouts. These Nuun tablets, which are packed with electrolytes and have only two grams of sugar, are steeply discounted. Right now, you can get a four pack for 53 percent off, which is among the lowest prices we’ve seen.
I like popping these tablets in my water bottle whenever I’m feeling under-hydrated during the day or if I’ve got a high-mileage workout on my running training schedule. I keep them in my hiking pack so I can get a boost of electrolytes on the trail as well. (Nuun also makes a caffeinated version, which I like to use when I don’t have coffee nearby.) These electrolyte tabs are a favorite of former Strategist senior writer and marathoner Karen Iorio Adelson, who likes how they aren’t loaded with sugar, unlike overly sweet sports drinks. Adelson also uses them to help cure hangovers.
