Electrolyte Brands Under Review: What LMNT, Liquid I.V., Nuun and Others Actually Offer

Hydration support has moved well beyond plain water, and electrolyte powders have become a regular part of workout bags, desk drawers and kitchen counters. The category now includes zero-sugar mixes for low-carb routines, high-sodium formulas built for heavy sweating and clinical-grade options designed for serious dehydration.

With so many products on the market, knowing what each formula actually delivers — and what dietitians and reviewers say about them — can make the difference between an effective hydration habit and a sugary placebo. Below is a breakdown of six widely covered electrolyte powders and tablets.

How electrolyte powders compare on sodium, sugar and flavor

Electrolyte products vary widely in how much sodium they pack, whether they include sugar and how they handle taste. Some lean into glucose to speed absorption, while others go zero-sugar and use stevia or monk fruit as sweeteners. Sodium content can range from a few hundred milligrams to a full gram per serving, depending on whether the product is built for everyday hydration or heavy endurance work. Reviewers and registered dietitians frequently note that flavor and tolerance during workouts matter just as much as the nutrition label.

Cure Hydrating Drink Mix

Cure positions itself as a low-sugar option sweetened with stevia and monk fruit. It comes in several flavors, giving drinkers options depending on taste preference. As with many stevia-sweetened products, the aftertaste is something some people notice and others tolerate easily.

Katey Davidson MScFN, RD, CPT with Healthline writes: “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 Hydration tablets

Nuun is one of the most widely known electrolyte tablet brands. Instead of a powder, it comes in effervescent tablets that dissolve in water and turn it into a low-calorie electrolyte drink. The brand is positioned more as a daily hydration and endurance support product rather than a high-sugar sports drink, making it a go-to for people who want a lighter option throughout the day.

A Nuun Sport tablet typically contains:

• Potassium: 100–150 mg
• Sodium: 300–360 mg
• Magnesium: 25 mg
• Calcium: 0–15 mg

LMNT Zero Sugar Electrolytes

LMNT is a high-sodium, zero-sugar electrolyte mix designed for heavy sweating and low-carb hydration. Each packet delivers a notably higher sodium dose than most competitors, which appeals to athletes, keto eaters and anyone working out in heat. The brand’s variety pack offers multiple flavors, which can help with long-term tolerance during repeat workouts.

Typical nutrition per packet:

• Potassium: 200 mg
• Magnesium: 60 mg
• Sugar: 0 g
• Sodium: 1,000 mg

Sarah Alsing, MS, RD, told Men’s Health: “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 combination of glucose and sodium aimed at fast absorption and hydration support. The formula leans on a small amount of sugar to help the body take in electrolytes more efficiently — a tradeoff that can be helpful for athletes but less ideal for anyone watching carbs.

Typical nutrition for the original formula:

• Sodium: ~500 mg
• Potassium: ~370 mg
• Sugar: ~11 g
• Calories: ~45

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 Electrolyte Powder

DripDrop is designed by doctors for clinical-level dehydration support, putting it in a different category than typical sports hydration mixes. The formula is gluten-free, soy-free and certified vegan, and it does not rely on stevia, which sets it apart from many low-sugar competitors.

Typical nutrition:

• Sodium: 330 mg
• Potassium: 185 mg
• Magnesium: small amount
• Sugar: 7 g

According to Lauren Kary with Men’s Health: “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 Hydration is built around a low-sugar, plant-based, clean-ingredient approach. Typical formulas contain around 2 grams of sugar per serving, with no artificial dyes or sweeteners, and the brand offers both caffeinated and caffeine-free versions to suit different routines.

The caffeinated formula adds natural caffeine from green coffee bean extract — typically around 150 mg per serving — along with L-theanine, included to smooth out jitteriness.
