Americans shell out over $10 billion annually on sports drinks, pursuing promises of optimal hydration and increased well-being. But the catch: for most of us, these flashy bottles and cool electrolyte powders are as much about marketing savvy as genuine need.
Electrolytes let’s think sodium, potassium, magnesium, and calcium certainly play behind-the-scenes MVPs for our bodies, keeping muscles humming, nerves transmitting, and fluids in check. Big drink companies adore touting this, with Gatorade boasting “nearly one-eighth teaspoons of salt and 80 milligrams of potassium” per one 20-ounce bottle, and Powerade boasting “50% more electrolytes” than its competitor. Influencers and commercials make it seem like everyone must replenish their electrolytes just to make it through a hectic day. Is that actually true, though?
As sports scientists and physicians, most individuals derive all the electrolytes their bodies require from a normal diet no expensive beverage necessary. Tamara Hew-Butler, a well-known sports scientist, simplifies it like this: If you eat a decent diet, you’re going to get all of the electrolytes that are required to function. The truth is “in the Western diet, we take in three times the amount of sodium we actually require.” What that means for the average gym rat or weekend day-hiker is plain water and a rainbow of fruits and vegetables is more than sufficient to maintain hydration and electrolyte balances.
The body is a pro at regulating itself. Kidneys, under the direction of hormones, fine-tune sodium and water with amazing accuracy. Lose a small amount of salt? Hormones tell the kidneys to reabsorb the sodium. Consumed too much? The extra is washed out in your urine. Calcium and magnesium? They’re stored in your bones, waiting to be tapped if you need a transfusion. As Hew-Butler explains, Urine regularly contains electrolytes and if they’re coming out in your pee, it’s because your body has more than it needs.
So, when should you really grab an electrolyte drink? The answer: only in certain circumstances. Endurance athletes, individuals exercising strenuously for more than an hour, or those losing fluids quickly from illness (read: vomiting or diarrhea) might find it beneficial to quickly replace electrolytes. Sports dietitian Haley Wilson describes the convenience of sports drinks for student athletes who “sometimes don’t eat enough for how active they are.” And Asher Rosinger, director of the Water, Health, and Nutrition Lab at Penn State, points out that those who are running a lot or just sweating a ton in the sun may need to replace those electrolytes promptly. For everyone else, “good old-fashioned, plain water” does the trick.
But hold off on buying those neon bottles, first. There are drawbacks to many sports drinks. They are filled with sugar and sodium up to 21 grams of sugar and 299 mg of sodium per 12-ounce serving. Too much of a good thing can translate to weight gain, tooth decay, and even risk of developing high blood pressure and cardiovascular disease. The American Academy of Pediatrics warns that “excessive consumption of sweetened sports drinks in adolescents is associated with weight gain, obesity, dental caries, poor nutrition, and diabetes.” And for non-athletes, “water is sufficient to maintain adequate hydration during physical activity.”
If you’re looking for a healthier, wallet-friendly alternative, natural foods and DIY drinks are the way to go. Milk, orange juice, coconut water, and broths are naturally rich in electrolytes. Or make your own mix: combine water with a pinch of sea salt, a splash of citrus juice, and a bit of honey or maple syrup. This homemade alternative bypasses artificial colors and added sugars, providing you with the minerals you require no marketing gimmickry needed.
The takeaway? Unless you’re sweating buckets for hours on end or fighting off a gross stomach bug, your body’s already got its electrolyte thing in check. Ditch the pricey powders and just stick to water and a healthy diet. As Dr. Sara Rosenkranz reminds us, “For most people, it is absolutely true that we get adequate amounts in the foods and beverages that we consume already.”
