The Best Electrolyte Supplements to Keep You Hydrated

We all know that hydration is key for good health and for your body to function properly. Just think about how sluggish and icky you feel when you haven’t guzzled enough H20. 

So it makes sense, then, that electrolyte supplements (also known as hydration supplements) would be all the rage these days. What exactly are electrolytes, how can they benefit you, and how do you choose the right hydration supplement? Here’s what you need to know.

What are electrolytes?

“Electrolytes are essential minerals that are key for many functions in the body,” explains Brooke Alpert, RD, founder of B Nutritious and advisor for Cure Hydration. (Sodium, calcium, and potassium are a few examples of these minerals.)

“While they’re mainly known as an addition to a beverage post-sweaty activities, they do much more than just balance the amount of water that your body can absorb,” says Alpert. Electrolytes can also help nutrients move into your cells and waste out of your cells. They can also help with your central nervous system, which is how your body is able to remain walking and talking.

What are the benefits of hydration supplements?

You mostly lose electrolytes through sweating and peeing, so hydration supplements packed with electrolytes can be beneficial to take after a workout. In fact, Alpert says that when you sweat, you can lose up to two to three liters of fluid an hour, which is all the more reason why you need more fluids. 

These fluids need to be properly absorbed, though, and good ol’ H20 may not be able to do the job alone. “Water on it’s own is sometimes not enough because without proper electrolytes, the water isn’t absorbed as effectively and often you just end up in the bathroom more,” says Alpert. 

Alpert adds that electrolyte supplements are the most effective way—aside from an IV—to boost hydration and electrolyte intake. “Put simply, adding electrolytes to your water means you are hydrating more effectively than water alone,” she says. 

Hydration supplements can even prove beneficial if you’re doing intermittent fasting (IF). “For those who like IF, electrolytes can certainly be added in during the fasting time,” says Alpert. 

A lot of the healthy foods we eat—fruits and veggies, especially—also provide fluids to your diet. “When you’re fasting, not only are you not eating food, but you’re also missing out on the additional fluids that you probably didn’t even consider,” says Alpert. “Adding electrolytes to your non-caloric drinks during the fasting time can help to keep you adequately hydrated and keep you able to stick to your fasting rules more easily.”

What are the best electrolyte supplements? 

There are two main things Alpert looks for in an electrolyte supplement. “One is the proper balance of electrolytes to optimize the absorption,” she says. “The second is what’s not in it like added sugars, colors, and dyes—when I look for an electrolyte, I want nutrition, not a neon colored artificial beverage.”
