When you’re sweating your butt off, sometimes water isn’t enough to fully rehydrate you. That’s because you lose more than just water when you perspire: Sweat is also made up of electrolytes like sodium and potassium, so a major workout can leave you with an imbalance that makes you endlessly thirsty. Luckily, the best electrolyte drinks can help bring your body back to baseline.

How? Well, electrolyte hydration solutions include the minerals that help manage the fluid balance in our bodies to keep us hydrated. “The different electrolytes manage the shift between what’s going in the cell, what’s staying inside the bloodstream, and your plasma volume to make sure that everything’s flowing the way that it should,” explains Tim Dileo, MS, RDN, CSSD, assistant director of athletics for sports nutrition at the University of Connecticut and a registered dietitian with Top Nutrition Coaching. Meaning: Electrolytes help the fluid we’re drinking get to where it needs to go inside our bodies.

While we can certainly get electrolytes from food, Danielle Smith, RDN, LDN, another registered dietitian nutritionist with Top Nutrition Coaching, says that food alone doesn’t usually provide the necessary amounts. That’s where sports drinks and rehydration formulas step in to ensure that you’re hitting your daily targets and staying well-hydrated, no matter what’s on the menu.

Who can benefit from an electrolyte drink?

Anyone! But electrolyte drinks are most often recommended to athletes or people with strenuous jobs, like construction workers and landscapers working out in the elements. “If you’re doing a really intense workout or if you’re out in the heat, that’s the time when you’re going to want the electrolyte beverage to replace what you’re losing in sweat,” says Dileo. You’ll want to sip it throughout the entire time you’re sweating and after you’re done, adds Smith.

But it’s not just super-active people who can benefit from electrolyte drinks. “I often recommend that people start out the morning with electrolytes, just because I find that having an adequate balance of electrolytes really does help with overall hydration and just not feeling as thirsty,” Smith says.

Electrolyte drinks can also be particularly helpful when you’re sick or dealing with GI issues like diarrhea that leave you struggling to stay hydrated. Additionally, Smith recommends electrolyte drinks to people who are pregnant or breastfeeding, when maintaining adequate hydration is essential.

What to look for in an electrolyte drink

There are a lot of electrolyte drinks on the market today. Quality can vary, and certain varieties serve different purposes. So you’ll want to take a close look at the labels before purchasing. Keep an eye out for these five things:

Percentages: Consuming too many electrolytes when you don’t need them can have adverse side effects on things like kidney function, so check the nutrition facts on the back to see what you’ll be getting from each serving. “Some might have sodium levels that are in the 100 to 200 milligram range. And then you have other ones that are 1,000, or 1,700 milligrams,” says Dileo. If you’re not sweating so much that you need excessive amounts, choose an electrolyte drink with more moderate levels of each mineral.

Sugars: Added sugars can be helpful for workouts longer than an hour when you want to be taking in simple carbs for energy. Otherwise, you’re just drinking unnecessary extra sugar.

Sugar alcohols: Some zero-sugar electrolyte drinks might contain sugar alcohols like sorbitol or xylitol to sweeten the taste. But these can cause bloating or gas, so be cautious, warns Dileo.

Third-party testing: Smith recommends looking for products that are third-party tested. “That ensures that there are not going to be things like heavy metals, and also ensures that the amount of sodium, potassium, other electrolytes listed are actually there in the quantities that they say,” she says.

Straightforward ingredients: Smith says she only chooses electrolyte drinks with simple ingredient lists. “If I see something like red dye 40, I’m not going to consume it,” she says.

Dileo uses this doctor-formulated powder with the athletes at UConn—both the zero-sugar version and the version with some sugar for extra carbs to fuel long workouts. Crafted with a perfect balance of sodium, potassium, and other essential electrolytes, DripDrop is his go-to beverage for replenishing fluids and restoring vital nutrients lost during intense workouts, illness, or simply hectic days. There’s also a burst of vitamin C in each hydration stick, which can help aid with immunity.

And each stick is loaded with electrolytes; there’s 1000 mg of sodium, 200 mg of potassium, and 60 mg of magnesium, to be exact.

For super-sweaters, Dileo recommends The Right Stuff, which was developed by NASA to hydrate astronauts. “For some of my athletes who sweat quite a bit, who have a history of cramping and are about to play a game or [have] a long practice, I’ll give them that higher dose sodium drink to help with the rehydration,” he says. Made with sea salt, each packet of liquid concentrate has 1780 milligrams of sodium, or 77 percent of your daily value. That’s an extreme amount, so Dileo suggests only using this if you know you’re a really heavy sweater.

How can you tell if you need electrolytes?

The signs you need electrolytes can vary, but generally, if you’re experiencing persistent fatigue, muscle cramps, or even brain fog, chances are, your electrolyte levels could use a boost. Keep an eye out for signs like increased thirst, frequent headaches, or even a sudden onset of dizziness—these are all red flags that your electrolyte levels might be out of whack.

Is there a downside to drinking electrolytes?

Overconsumption of certain electrolytes, particularly sodium, can pose risks for individuals with specific health conditions such as hypertension or kidney issues. Talk to your doctor before buying a sports drink to see if they’re safe for you.
