The Best Electrolyte Powders of 2024

ProMix Electrolyte Drink Mix ($42)

ProMix's electrolyte powder comes in unflavored and grapefruit varieties that are unsweetened, as well as a monk fruit-sweetened lemon-lime version. Each contains 1,000 mg of sodium, making them a higher-sodium pick, plus 200 mg of potassium and 60 mg of magnesium. ProMix relies on third-party lab testing to verify the purity of its supplements, and you can view the results from your product's batch on the brand's site.

Customer Quote: "I'm a big fan of the unsweetened grapefruit, so I was curious to try the lightly sweetened lemon-lime. It is quite good! I often find that drinks are too sweet for me, but this one was just right. I also love that they use monk fruit because it doesn't have an off-taste like stevia."
