Sports drinks, or electrolyte-enhanced beverages, help to replenish water, electrolytes, and energy lost during exercise. These drinks often contain a source of energy-boosting carbohydrates, as well as a balance of potassium, sodium, magnesium, and calcium, which help combat dehydration, replete glycogen stores, and delay fatigue. The American College of Sports Medicine recommends that individuals partaking in vigorous exercise for one hour or longer consider drinking a carbohydrate-based sports beverages, especially if they are sweating heavily.

There are many options on the market when it comes to sports drinks, including ready-to-drink beverages and mix-with-water tablets or powders. Consider your calorie, sugar, and electrolyte needs when choosing a product that suits your hydration requirements.

Here, the best sports drinks:

Best Higher-Carbohydrate: Gatorade Thirst Quencher

When you think of sports drinks, Gatorade is probably the first brand that comes to mind. Created in the summer of 1965 by a football coach at the University of Florida, this thirst-quenching drink was made with athletes in mind to help them replenish and recover after a tough workout.

The formula is simple—it has an electrolyte and carbohydrate base, which is essentially what is lost after sweating in the heat, and a sweet flavor to entice you to drink. Favored on the sidelines of the NFL for 44 years, this go-to sports beverage is a preferred drink for many professional athletes as well as active adults.

Gatorade is budget-friendly and available almost everywhere, making it an easy option to buy after a long run in the sun. While it does have a lot of sugar in it, this can be helpful for endurance athletes looking for a quick source of easily digestible carbs.

For those who want to watch their sugar consumption but love the taste, consider mixing a few tablespoons of Gatorade with cold water for a refreshing electrolyte drink. It comes in a variety of flavors, including Lemon-Lime, Orange, and Fruit Punch.

Best Powder: Ultima Replenisher Electrolyte Hydration Powder

Best Single-Serve: Ultima Replenisher Electrolyte Hydration Powder

Ultima Replenisher

Ultima Replenisher Electrolyte Powder is an excellent choice for a sugar-free beverage that will replenish electrolyte levels, hydrate effectively, and provide supporting minerals.

Each 8-ounce serving of Harmless Harvest Coconut Water provides 15 grams of carbohydrates and 60 calories to help replete glycogen stores.

What to Look for in an Electrolyte Drink


Sports drinks come in many forms, including ready-to-drink beverages, powders, and tablets. If you are looking for the easiest, grab-and-go option, a ready-to-drink sports drink is usually available at any grocery or convenience store. If you travel frequently or simply want a more portable sports drink, choosing a tablet or powder that you mix with water may be preferable.


When you sweat, your body loses fluid and electrolytes. Sports drinks contain electrolytes—including potassium, sodium, magnesium, and calcium—to help combat dehydration. They work with your body to improve the absorption of fluid and replenish mineral losses. Look for a sports drink that contains at least sodium and potassium.


If you are engaging in endurance activities or strenuous sports, you may need a sports drink that is high in calories. When choosing a sports drink, consider your activity level, caloric expenditure, and energy needs. You may choose a sports drink higher in calories if you are training for a marathon. However, if you are exercising for over an hour but trying to lose weight, you may want to replete electrolytes without consuming extra calories.


Many sports drinks contain sugar to help athletes replace carbohydrates lost during exercise quickly. If you watch your sugar intake or prefer a sugar-free option, some tablets and powders are low in sugar. Avoid sugar-free sports drinks that contain potentially harmful artificial sweeteners.

What Experts Say

"When choosing a sports drink for a super sweaty workout—or over an hour of exercise—I recommend looking for a beverage with at least 300 milligrams of potassium and at least 80 milligrams of sodium. A beverage like coconut water—with minimal added flavors and colors—is my favorite." — Isabel Smith, MS, RD, CDN

Why Trust Verywell Fit?

A personal note on my recommendations written above. As a dietitian, I frequently work with athletes ranging from weekend warriors to triathletes who may need to use electrolyte drinks. After spending time reviewing the most current clinical research and looking at multiple products, I came up with a list of products that I would recommend to someone looking to add sports drinks into their routine. I am careful to suggest sports drinks, as many of them contain high amounts of sugar that are not necessary for everyday activity; however, some people do require a boost for more intense exercise and conditions. I believe that the products in the round-up are made by trusted brands.

As a marathoner, I have tried various electrolyte products, including most of the products on this list. When running, I use Ultima, Nuun, or Harmless Harvest Coconut Water. If a race only offers Gatorade, I will take a small sip and follow it with a sip of water. — Eliza Savage, MS, RD, CDN
