Liquid I.V.Hydration Multiplier

Overview

Liquid I.V.'s Hydration Multiplier packs 500 mg of sodium, 370 mg of potassium, and 11 g of sugar into a 16 g stick, plus vitamin C and four B vitamins (B3, B5, B6, and B12). The glucose-plus-sodium pairing comes from oral rehydration science, where a bit of sugar helps the gut absorb sodium and water. It sells in 16-stick packs for around $24, and its official TikTok Shop store has moved hundreds of thousands of units; the Cotton Candy flavor alone lists more than 200,000 sold.

What reviewers say

Taste is the runaway win. Reviewers and TikTok creators rave about Lemon Lime, Passion Fruit, and limited flavors like Cotton Candy. BarBend rated it 4 out of 5, calling it useful for endurance athletes and long, sweaty sessions while noting cheaper alternatives and no third-party testing details. The sport scientist and dietitian team at Saturday was far harsher, arguing the long ingredient list and high potassium make it closer to a flavored drink than a performance tool. Registered dietitians on YouTube and TikTok land in the middle: helpful when you're sweating heavily or out in the heat, unnecessary for most desk days.

Who it's for

Recreational exercisers, travelers, and anyone who struggles to drink plain water and wants something that tastes like a treat. It also fits long, hot sessions where the sugar doubles as useful fuel.

Bottom line

Liquid I.V. earns its viral status on flavor and convenience, and its sodium dose is respectable. But with 11 g of added sugar and a premium price, it's hard to justify as an all-day drink. If sugar is a concern, the brand's sugar-free line or a zero-sugar pick like Ultima makes more sense.
