Liquid I.V. Review: Buy the Sugar-Free, the Electrolytes Are Identical

1. The labels, and the company behind them

We did not take the nutrition figures from marketing copy. We located the Nutrition Facts panel images published on each product page and read them directly, which is how we can state every quantity in the comparison table above. The original's full ingredient list, also published on the page, runs: cane sugar, dextrose, citric acid, salt, potassium citrate, sodium citrate, dipotassium phosphate, silicon dioxide, stevia leaf extract, natural flavors, vitamin C, vitamin B3, vitamin B5, vitamin B6 and vitamin B12. Cane sugar first, which is consistent with 11g of a 16g stick.

The company's own structured data gives a founding date of 2012, an address at 777 S Aviation Blvd, Suite 105, El Segundo, California, and names Unilever as the parent organisation. That is worth knowing in both directions: a multinational parent means real manufacturing and quality systems and someone to complain to, and it also means the brand's wellness positioning sits inside a consumer goods portfolio. Unilever also owns Nutrafol, which we have reviewed separately.

Pricing was clear and unusually well behaved. A 16-stick carton of the original was $24.99 outright, which the page itself breaks down as $1.56 a stick, or $17.49 on subscription at $1.09 a stick — a 30% subscription saving. The sugar-free carton holds 14 sticks at $21.84, the same $1.56 each. Free shipping applied over $40. Notably, the page's default purchase selection was one-time rather than subscription, which is the opposite of the pattern we usually find and worth crediting.

2. The claims worth pushing back on

The name is the biggest one. Liquid I.V. invites a comparison with intravenous fluid, and no powder dissolved in a glass is equivalent to an intravenous drip, which bypasses the gut entirely and is administered for clinical dehydration. The company does not state that equivalence outright, and its own materials describe the product as an oral rehydration solution, which is accurate. But the brand does the work the copy avoids.

Three times the electrolytes of the leading sports drink is technically a comparison rather than a claim, and it needs reading as one. It tells you this contains more sodium and potassium than a drink formulated for a different purpose; it does not establish that three times as much is better for a person sitting at a desk. Similarly, faster hydration than water alone is defensible in the context of fluid loss and much weaker as a general proposition for someone who is simply thirsty.

The sodium deserves more prominence than the marketing gives it. Five hundred milligrams a stick is 22% of the daily value, it is present in both versions, and it is the ingredient most likely to matter clinically to this readership — hypertension being common alongside obesity and type 2 diabetes. The product is not marketed with any caution about that, and the FAQ headline asking why Liquid I.V. contains high levels of sodium suggests the company knows customers notice. One a day is a non-issue for most people. Reaching for three on a hot day, while managing blood pressure, is a different calculation.

3. Alternatives, including the free one

The honest comparison starts with water, which is free and adequate for most everyday under-drinking in someone eating normally. Beyond that, the World Health Organization's oral rehydration formulation is public and can be mixed at home from salt, sugar and water for pennies a serving; pharmacies also sell standard oral rehydration sachets designed for illness, which are typically cheaper than a wellness-branded stick. Nothing about Liquid I.V.'s chemistry is proprietary.

What you are actually buying at $1.09 to $1.56 a stick is convenience, consistent dosing, flavour that makes you drink more, and a sachet you can carry. Those are real benefits and we are not going to pretend otherwise — a product you will actually use beats a better one you will not. The B vitamins and vitamin C are the least useful part of the package for most people, though B12 has some relevance for those eating substantially less food.

On independent signal we came up short, which is a real limitation here. The rating displayed on the product page was 4.9 out of 5 from 4,926 reviews, but those are first-party reviews collected and shown by the brand, and we could not obtain any independent review-platform aggregate for comparison. Treat that number as what the company chose to publish rather than as verification.

What is Liquid I.V.?

A powdered electrolyte drink mix sold in single-serve sticks that you add to water. The flagship product is Hydration Multiplier. Its own structured data gives a founding date of 2012, an address in El Segundo, California, and Unilever as the parent organisation. On 12 August 2026 a 16-stick carton of the original was $24.99 one-time, which works out at $1.56 a stick, or $17.49 on subscription at $1.09 a stick.

What is the single most useful thing in this review?

That Hydration Multiplier Sugar-Free contains exactly the same electrolytes and vitamins as the original, at exactly the same doses. We read both nutrition panels side by side. Both give 500mg sodium and 370mg potassium. Both give 62mg vitamin C, 19.3mg niacin, 1.93mg vitamin B6, 5.79mcg vitamin B12 and 9.6mg pantothenic acid. The differences are that the original has 50 calories and 11g of added sugar, and the sugar-free has 20 calories and none. If you are buying this for the electrolytes, the sugar-free version is the same product without the sugar.

How much sugar is in the original?

Eleven grams per stick, all of it added sugar, which the label records as 22% of the daily value. The stick itself weighs 16g, so roughly two thirds of what you are tipping into the glass is sugar, and cane sugar is the first ingredient on the list ahead of dextrose. That is 50 calories. As a one-off it is unremarkable. As a daily habit taken alongside a medication prescribed for weight loss or blood glucose, it deserves a moment's thought.

Isn't the sugar there for a reason?

Yes, and we want to be fair about this because it is real science rather than marketing. Oral rehydration solutions work through sodium-glucose cotransport: glucose being actively absorbed in the small intestine pulls sodium across with it, and water follows. That is the principle behind the oral rehydration therapy used worldwide for diarrhoeal illness, and it is genuinely why a rehydration drink contains sugar rather than being sweetened as an afterthought. So the glucose in the original has a job.

Then why recommend the sugar-free one?

Because the mechanism matters most when you are actually losing fluid fast, and most people drink this on ordinary days. Cotransport-driven rehydration earns its keep during vomiting, diarrhoea, heavy sweating or illness. For someone who simply has not drunk enough water, the electrolytes and the fluid do most of the work and the glucose is a smaller factor. Liquid I.V. clearly agrees that a sugar-free option is viable, because it sells one and puts the same electrolyte load in it. For everyday use on a GLP-1, take the identical minerals and skip the 11g.

When would I want the original instead?

If you are genuinely dehydrated from fluid losses — a bout of vomiting or diarrhoea, which are among the more common adverse effects of these medications, or a hot day with heavy sweating — the glucose-containing version has the stronger mechanistic case, because that is the situation oral rehydration therapy was designed for. If you are vomiting persistently, cannot keep fluids down, or feel faint, that is a call to your prescriber rather than a drink mix.

Is the sodium a problem?

It is the thing we would actually watch, and it does not go away when you drop the sugar. Both versions contain 500mg of sodium per stick, which the label puts at 22% of the daily value. One stick a day is fine for most people. Several sticks a day, on top of a normal diet, is a meaningful sodium load — and high blood pressure is common among people carrying excess weight or living with type 2 diabetes. If you have hypertension, heart failure or kidney disease, this is a product to run past your clinician rather than one to drink freely.

Does it hydrate you better than water?

For genuine dehydration with electrolyte loss, an oral rehydration solution does outperform plain water, and that is well established. For mild everyday under-drinking in a healthy person eating normally, water and food supply what you need and the evidence for needing a supplement is much thinner. The brand name invites a comparison with an intravenous drip which no powdered drink can support, and the claim of three times the electrolytes of the leading sports drink is a comparison with a sugary sports drink rather than a statement that more electrolytes are better for you.

Why does hydration matter more on a GLP-1?

Because several things push the same way at once. Appetite suppression reduces how much you eat, and a substantial share of daily fluid normally arrives in food. Nausea makes drinking less appealing. Vomiting and diarrhoea cause direct losses. And dehydration makes constipation — one of the most frequently reported effects of these drugs — considerably worse. There is also a kidney consideration: dehydration on top of vomiting or diarrhoea is the route by which acute kidney injury has been reported with these medicines, which is why fluid intake is worth taking seriously rather than treating as a wellness nicety.

Could I just make this myself?

Broadly, yes. The active part of the formula is sodium, potassium, water and a little sugar, and the World Health Organization's oral rehydration formulation is public. Homemade versions cost pennies. What you are buying here is convenience, flavour, consistent dosing and a sachet that fits in a pocket, plus B vitamins and vitamin C you probably do not need. Those are legitimate things to pay for, but they are what you are paying for.

Is the labelling honest?

On the numbers, yes, and it deserves credit for it. Full nutrition panels are published for both versions with every quantity stated, the complete ingredient list is on the product page, and the sugar content is not disguised. We have spent a lot of this year reviewing supplement brands that publish no doses at all, so a company that prints every figure is doing the basic thing right. Our criticisms are about how the product is framed and who it suits, not about concealment.

How much do you earn from this?

Five per cent on a purchase and one per cent recurring, which is among the lowest rates we carry. The advice on this page is to buy the cheaper-per-calorie option or make it yourself, so we are not optimising for the payout.
