Liquid I.V. Hydration Multiplier Review: Would Buyers Buy It Again?

Depends

Useful when you sweat a lot, unnecessary for most daily drinking

Each original stick has 11 g of sugar and 500 mg of sodium, and Garage Gym Reviews found it dissolves well and comes in many flavors. That makes sense for long, sweaty workouts, physical jobs or hot days. But dietitians writing for Food Network and The Balanced Nutritionist say most people get enough from plain water, and that much extra sodium is not needed for the average person. Owners on Thingtesting rate it 4.1 out of 5, with sugar the most common complaint and taste split between too sweet and too salty. Buy it for specific situations, or consider the sugar-free version.

Buy it again if you…

• do long or intense workouts, or sweat heavily
• work or exercise outdoors in hot weather
• want convenient single-serve sticks for travel or the gym bag

Skip it if you…

• want a drink for everyday sipping at a desk
• need to limit sodium, for example with high blood pressure
• are cutting added sugar (consider the sugar-free version)

This review summarizes buyer experiences and expert commentary and is not medical advice. Dietary supplements are not evaluated by the FDA to treat, cure or prevent any disease. Check with a doctor or pharmacist before using electrolyte drinks regularly, especially if you have high blood pressure, kidney or heart problems, diabetes, are on a sodium-restricted diet, take medication, or are pregnant. For severe dehydration, seek medical care.

Liquid I.V. Hydration Multiplier is an electrolyte drink mix in single-serve sticks that you stir into about 16 oz of water. The original formula combines sodium, potassium and glucose, which the brand says helps water absorb faster. A sugar-free version is sold separately, and other Liquid I.V. lines add caffeine or other ingredients, so check which product you are buying.

We looked at expert reviews, dietitian commentary and owner review themes to see who it is actually worth it for.

The key details

What buyers love

What buyers complain about

Do you actually need an electrolyte drink?

For most people, no. A dietitian writing for Food Network says adding this much sodium to your water is likely not necessary for the average person, since most Americans already eat more salt than recommended. The Balanced Nutritionist says plain water handles most everyday hydration and light or moderate exercise just fine.

Electrolyte drinks make more sense when you lose a lot of sweat: long or intense workouts, endurance events, physical jobs, or hot weather. In those cases the sugar can be useful, because glucose helps the body absorb sodium and water. Garage Gym Reviews notes a 2020 study found oral rehydration solutions rehydrated better than traditional sports drinks after exercise, and says the formula is described as meeting WHO oral rehydration standards, though it is unclear whether WHO has evaluated this product.

Compared with an average sports drink, Food Network's dietitian notes Liquid I.V. has far more sodium and potassium per serving. People with high blood pressure or on a low-sodium diet should ask a doctor before using it.

How it compares

LMNT has about 1,000 mg of sodium per packet and no sugar, which The Balanced Nutritionist says suits heavy sweaters and endurance athletes rather than casual daily use. Liquid I.V. sits in the middle with 500 mg of sodium and added sugar in the original version, and its sugar-free version uses allulose instead. Nuun tablets are a fizzy alternative you drop into water.

Tips from buyers

• Save it for sweaty days and drink plain water the rest of the time.
• Add more water if it tastes too salty or sweet.
• Try the sugar-free version if you are watching sugar.
• Check the product line, since some Liquid I.V. versions add caffeine or other active ingredients.
