Liquid IV Ingredients: What’s in the Stick, and Why It Works (2026)

Last reviewed: October 2026. Reflects the current U.S. Liquid I.V. Hydration Multiplier, Lemon Lime, one 16 g stick mixed into 16 oz of water, read from the box in store. Sugar-Free is compared below. Liquid I.V. has been owned by Unilever since 2020; the box lists The LIV Group Inc. as distributor and Canada as the country of manufacture.

Liquid I.V. is the powder that made “electrolytes” a thing people buy in sticks. Its pitch has always been that it hydrates faster than water — the box says so in big type — and the brand calls the idea “Cellular Transport Technology.” Read the label and the technology is an old one: salt, sugar, and potassium in water, the oral rehydration principle the World Health Organization built its rehydration salts on in the 1970s. That’s not a knock; it’s the reason Liquid I.V. is the one product in this category that works for what it’s sold for. It’s also why it has 11 g of sugar and 560 mg of sodium, which matter more than the brand’s “one stick a day” suggestion lets on. Here’s all the Liquid IV ingredients from the current box, how close it really is to medical rehydration solutions, and when you actually need it.

Quick answer: what’s in Liquid I.V.?

The full Liquid IV ingredients list

Three things to notice. Sugar is the first ingredient by weight — the stick is mostly sugar, which is part of how the formula works rather than a flaw. Salt is fourth and sodium citrate sixth: two plain sodium sources, listed openly rather than as a branded “electrolyte blend,” which is how you get to 560 mg. And there’s no coconut water, no proprietary extract, and nothing undisclosed. Note also that this is a Nutrition Facts panel, not a Supplement Facts panel — Liquid I.V. is sold as a food, a drink mix, which matters for how its claims are regulated.

Liquid IV ingredients explained

Cane sugar and dextrose 11 g, and it’s doing a job

Together, 11 g per stick, all of it added — about 3 teaspoons, 22% of the daily value, a third of a Gatorade. In most drinks on this site, the sugar is the cost. Here it’s part of the mechanism: glucose is what pulls sodium, and with it water, across the intestinal wall. A rehydration drink without sugar absorbs more slowly; one with far too much (a regular soda) draws water into the gut instead. Dextrose is pure glucose; cane sugar is half glucose and half fructose. Liquid I.V. carries more sugar than the WHO formula — about 23 g per liter against the WHO’s 13.5 g of glucose — and lands closer to Pedialyte. The cost is still 11 g of sugar if you’re drinking it for taste.

Citric acid Fine

Tartness, and it makes the salt palatable — 560 mg of sodium in plain water tastes like seawater. Mildly acidic; the teeth note applies, though a stick drunk at once is less of an issue than a soda sipped for hours.

Salt and sodium citrate — 560 mg sodium The point

560 mg per stick, 24% of the daily value — twice Gatorade’s 270 per 20 oz, more than 20 times BodyArmor’s 25, and more than 50 times Prime’s. Sweat loses roughly 500–1,500 mg of sodium per liter, so after an hour of hard sweating, this is the first product on the shelf that replaces a meaningful fraction of it. Citrate rather than chloride for part of the sodium is the WHO’s choice too: it buffers the acid and is gentler on an upset stomach. If you’re not sweating, sick, or hungover, this is a quarter of your daily sodium you didn’t need; people on sodium-restricted diets should treat a stick as a meal’s worth of salt.

Potassium citrate and dipotassium phosphate — 370 mg potassium Fine

8% of the daily value. Potassium loss in sweat is small, so this is a supporting player; the ratio to sodium (about 1.5 to 1) is sensible, and the reverse of BodyArmor and Prime.

Silicon dioxide Fine

An anti-caking agent so the powder pours. Essentially fine sand; inert and excreted.

Stevia leaf extract (Rebaudioside A) Low concern

Reb A is the purified sweet compound from the stevia leaf, a zero-calorie sweetener that tops up the sweetness without adding sugar beyond what the formula needs. Clean regulatory record; the only thing some people notice is its aftertaste. The box says “no artificial sweeteners,” and that’s accurate — stevia is plant-derived.

Vitamin C (ascorbic acid) Fine

62 mg, 70% of the daily value. No benzoate on this label, so the benzene pairing covered in our sodium benzoate breakdown doesn’t apply — a dry powder doesn’t need a preservative.

Natural flavors Undisclosed

Lemon lime, or whichever flavor. Plant-derived; proprietary.

B vitamins (B3, B5, B6, B12) Overdosed, harmless

Niacin at 120% of the daily value, B6 at 110%, pantothenic acid at 190%, B12 at 240%. They don’t aid hydration or energy in people who aren’t deficient; they’re here for the “8 vitamins & nutrients” on the front of the box. Excess is excreted. The one worth a thought is B6 if you’re stacking several sticks a day with other supplements — chronic high intake is linked to nerve symptoms, though one stick is far below that level.

“Faster hydration than water” — and the ORS science behind it

The claim on the box is “faster hydration than water alone,” and the brand’s name for why is Cellular Transport Technology. What it describes is sodium-glucose cotransport, worked out in the 1960s: a protein in the gut wall (SGLT1) moves sodium and glucose across together, and water follows. That mechanism is the basis of oral rehydration solution, the WHO formula credited with saving tens of millions of lives from diarrheal disease. Give someone salt and sugar in water in a sensible ratio and they absorb it faster, and retain more of it, than plain water.

How close is Liquid I.V. to the medical version? Closer to one than the other. The WHO’s reduced-osmolarity ORS, scaled to 16 oz, is about 815 mg of sodium, 370 mg of potassium, and 6.4 g of glucose. Liquid I.V. matches the potassium exactly, has about 70% of the sodium, and nearly twice the sugar — it’s sweeter and less salty than the clinical formula, which is a reasonable trade for something people drink voluntarily. Pedialyte, scaled to 16 oz, is about 490 mg of sodium, 370 mg of potassium, and 12 g of sugar — and Liquid I.V. is within a few percent of it on all three. So the fair description is an ORS-style drink built like Pedialyte, not a copy of the WHO solution.

Two honest caveats. The “faster than water” claim rests on the general ORS literature and the brand’s own testing, not on independent trials of Liquid I.V. specifically. And ORS was designed for people losing fluid to illness; for ordinary exercise, the evidence that a sodium-glucose drink beats water is strongest for sessions over an hour in the heat, and weak for anything shorter. Liquid I.V. works. It works for the situations ORS was built for, which are fewer than the marketing implies.

Liquid I.V. nutrition facts

Liquid I.V., Gatorade, and BodyArmor figures are from packages photographed for FittBeat in October 2026; Sugar-Free, Pedialyte, and Prime from current labels (Pedialyte Classic scaled from 12 oz); the WHO column is reduced-osmolarity ORS (75 mmol/L sodium, 20 mmol/L potassium, 13.5 g/L glucose) scaled to 16 oz. Read the sodium and sugar rows together: Liquid I.V. and Pedialyte are the same drink in different packaging, and the WHO formula is saltier and less sweet than both.

Liquid I.V. Sugar-Free

Swaps the 11 g of cane sugar and dextrose for allulose (a rare sugar that isn’t metabolized for calories) and stevia, and keeps the sodium and potassium. Without glucose, the sodium-glucose cotransport mechanism doesn’t engage, so it absorbs more like salted water — still useful for replacing sodium, somewhat slower on the “multiplier” claim. For someone avoiding sugar who sweats a lot, it’s the better everyday choice; for illness or a hangover, the original’s sugar is doing work. Allulose can cause mild stomach upset in some people at larger amounts.

When you actually need it

The box’s own suggestion is “1 stick per day for daily hydration,” with a note to check with a doctor before taking more for toddlers, pregnancy, breastfeeding, or medical conditions. That’s a marketing recommendation more than a physiological one; whether a stick does anything for you depends on whether you’ve lost sodium.

• After heavy sweat: an hour-plus in the heat, a hard practice, a long run. Yes — this is the product’s real use case, and it beats Gatorade on sodium and BodyArmor by a mile.
• Illness: vomiting or diarrhea in an adult. Yes — it’s an ORS-style drink, essentially Pedialyte in a stick. For young children, use Pedialyte, which is dosed and labeled for them.
• Hangover: alcohol is a diuretic and you’ve lost fluid and some sodium; a stick in the morning helps with that part. It doesn’t fix anything else.
• Travel, flights, “daily hydration”: usually no. You lose almost no sodium sitting in a seat or at a desk. A stick a day is 11 g of added sugar and 560 mg of sodium on top of a diet that, for most Americans, already has too much of both. Water.
• Short workouts: no. Under an hour, water is enough; the ORS benefit doesn’t show up until losses are substantial.

Is Liquid I.V. good for you?

The concerns, ranked by evidence:

1. Sodium, when unneeded. 560 mg is the design; for people on sodium-restricted diets or with high blood pressure, or anyone drinking one a day at a desk, it’s a lot.
2. Sugar, when unneeded. 11 g is modest and functional in the right context; daily use without sweat is just added sugar.
3. The “daily hydration” recommendation. Not a harm, but the biggest gap between what the product does and how it’s sold — now printed on the box.
4. Teeth. Mildly acidic; drunk at once, a minor issue.
5. Everything else. Stevia, vitamins, silicon dioxide: no concern at one stick.

Liquid I.V. for kids, keto, pregnancy, and blood pressure

Kids: for illness, Pedialyte is formulated and dosed for children, and the Liquid I.V. box itself says to seek medical advice before giving more than one stick to children ages 1–3. For sports, a kid needs it even less than an adult does.

Keto: the original has 13 g of carbs; Sugar-Free is near zero and the sodium is genuinely useful in the first weeks of keto, when sodium loss is common.

Pregnancy: no caffeine and no sweeteners of concern; fine as an occasional rehydration drink, with the sodium in mind. The box asks pregnant and breastfeeding users to check with a clinician before using more than one stick a day.

High blood pressure: 560 mg of sodium per stick is a meaningful dose. Occasional use after real losses is fine; daily use isn’t.

Cleaner alternatives

For the same thing, often cheaper: Pedialyte or a store-brand electrolyte powder, or a homemade ORS — the WHO’s home recipe is about half a level teaspoon of salt and six level teaspoons of sugar in a liter of water. For more sodium and no sugar: LMNT (1,000 mg, stevia). For less sodium and a cleaner label on an ordinary day: just water, which is the point of this section. Liquid I.V. isn’t the problem in this category; using it when you don’t need it is.
