Hydration powders have moved from the gym bag to the kitchen counter — and the lineup of options has exploded. Whether you sweat through long runs, follow a low-carb diet or just want to drink more water, picking the right electrolyte mix means looking past the marketing and reading the label.
Sodium counts, sugar grams and sweeteners vary widely between brands. Here is a breakdown of six widely discussed electrolyte products, what registered dietitians and reviewers say about them, and which one may fit your routine.
How Electrolyte Powders Work
Electrolyte powders and tablets dissolve in water to deliver minerals — typically sodium, potassium, magnesium and sometimes calcium — that the body loses through sweat. Some formulas add sugar to speed absorption, while others use stevia, monk fruit or sugar alcohols to keep calories low.
Why Everyone’s Obsessed With Instant Hydration Right Now
The right pick depends on how much you sweat and what you are trying to accomplish. Endurance athletes and heavy sweaters often need more sodium. People who want everyday hydration without added sugar tend to lean toward zero-sugar formulas.
Cure Hydrating Drink Mix
Cure leans into clean-label appeal with no added sugar. Katey Davidson, MScFN, RD, CPT with Healthline writes that “Cure Hydrating Drink Mix doesn’t have any added sugar but is sweetened with stevia and monk fruit and comes in a variety of flavors, like Strawberry Kiwi, Lemon, Watermelon, and more. As with most products using stevia, it’s worth noting that it does contain the distinct stevia aftertaste, which some people may dislike.”
Nuun Sport tablets
Nuun takes a different form factor — effervescent tablets that fizz into water rather than a powder you stir in. Each Nuun Sport tablet contains roughly 300 to 360 mg of sodium, 100 to 150 mg of potassium, 25 mg of magnesium and a small amount of sugar (often 0 to 2 grams depending on the version). Calcium runs from about 0 to 15 mg.
The brand is positioned as a daily hydration and endurance support option rather than a high-sugar sports drink. Flavoring is rounded out with stevia or sugar alcohols.
LMNT Zero Sugar Electrolytes
LMNT is built for heavy sweating and low-carb hydration, with a packet delivering roughly 1,000 mg of sodium — far more than most competitors — alongside 200 mg of potassium and 60 mg of magnesium. There is zero sugar.
Sarah Alsing, MS, RD, told Men’s Health that “there are several flavors to choose from, which helps finding one you will enjoy and tolerate during your workouts.”

Liquid I.V. Hydration Multiplier
Liquid I.V. uses a glucose-and-sodium combination designed for faster absorption. The original formula delivers roughly 500 mg of sodium, 370 mg of potassium, 11 grams of sugar and about 45 calories per packet.
Cam Vigliotta with Forbes says: “Each packet contains approximately 500mg of sodium, 370mg of potassium and 11g of added sugar. The sugar can help your body absorb the electrolytes more efficiently, but it’s not needed for everyday hydration. If you’re an athlete or engage in intense workouts, this could be a great option for you. But if you’re watching carbs or avoiding added sweeteners, you may want to opt for a zero-sugar option instead.”
DripDrop ORS
DripDrop was designed by doctors for clinical-level dehydration support. A serving has about 330 mg of sodium, 185 mg of potassium, a small amount of magnesium and roughly 7 grams of sugar.
Lauren Kary with Men’s Health writes: “This formula has 330 milligrams of sodium in each serving and is free from gluten, soy, and certified vegan. This formula does have 7g of added sugars and a total of 9 grams of carbohydrates but is also one of the few that does not use stevia as a sweetener.”

Gainful Hydration
Gainful keeps sugar low — around 2 grams per serving in some formulas — and avoids artificial dyes and sweeteners, leaning into a plant-based, clean-ingredient pitch. It is sold in caffeinated and caffeine-free versions.
The caffeinated formula adds natural caffeine from green coffee bean extract, typically around 150 mg per serving. Gainful also includes L-theanine to smooth out jitteriness.
Why Electrolyte Powders Matter for Everyday Drinkers
The category has grown well beyond competitive athletes. Some products, like LMNT, target people who lose a lot of sodium through heavy sweat or low-carb eating. Others, like Cure and Nuun, are pitched at daily hydration without piling on sugar. Liquid I.V. and DripDrop use sugar deliberately to speed absorption.
Reading the label is the key step. A 1,000 mg sodium hit makes sense after a hard workout but may be more than a desk worker needs. An 11-gram sugar packet is useful mid-marathon and less so with breakfast. Match the formula to the situation rather than the marketing.
