If you’ve ever stood in the supplements aisle wondering whether TruLabs or Liquid I.V. is the better hydration booster, trust me — you’re not alone. I’ve tested both on long workdays, gym sessions, and even during those lazy weekends when you’re just trying to recover from being dehydrated without realizing it. And while both brands promise better hydration, their approach, ingredients, and overall feel are VERY different.
Liquid I.V. leans on its famous Cellular Transport Technology (CTT) and has basically become the “default hydration powder” you see everywhere — from airports to Instagram. TruLabs, on the other hand, feels more like the “gym buddy” brand — cleaner formulas, no artificial junk, and a strong focus on performance hydration.
So in this comparison, I’ll break down how they actually feel in real use, what’s inside them, how they hydrate, and where each one genuinely stands out — not just what the marketing says. Let’s dive in!
What Is TruLabs?
TruLabs is a modern hydration and wellness brand that focuses on creating clean, high-quality drink mixes. Founded in 2018, the company set out to build formulas that actually support performance and daily hydration without relying on artificial colors, artificial sweeteners, or fillers. If you’ve ever tried their products, you’ll notice that TruLabs feels very “intentional” — every ingredient has a purpose, and nothing extra is thrown in just for marketing.
Their most popular product is TruLabs Hydrate, a zero-sugar electrolyte drink mix that comes in single-serve stick packs. What makes it stand out is how complete the formula is: it includes all five major electrolytes (sodium, chloride, potassium, magnesium, and calcium) along with 19 vitamins and minerals. It’s sweetened with monk fruit and Reb M instead of artificial sweeteners, so the taste is clean and smooth without that chemical aftertaste. TruLabs also offers variations like Hydrate + Detox, which adds DHM for antioxidant support, and Hydrate + Organic Greens, which combines hydration with superfoods like spinach, barley grass, kale, and oat grass.
One thing I personally appreciate about TruLabs is their overall philosophy. The brand leans heavily into natural ingredients, simplicity, and effectiveness. For example, they intentionally use sodium chloride instead of sodium citrate because some people experience bloating or discomfort with citrate-based electrolytes. It’s small details like this that make the brand feel more user-focused rather than trend-focused.
Beyond hydration, TruLabs also sells Energy + Focus mixes, pre-workout blends, and sleep formulas — all of which follow the same clean-label approach. Their hydration line is also expanding in retail settings, including Walmart in the U.S., making it easier for people to pick up stick packs on the go. Overall, TruLabs has quickly built a reputation as the “clean hydration brand” for people who want electrolyte support without sugar and without the usual artificial ingredients you see in bigger brands.
What Is Liquid I.V.?
Liquid I.V. is one of the most popular electrolyte drink mixes on the market, best known for its Hydration Multiplier — a powder that uses something called Cellular Transport Technology (CTT) to help your body absorb water and electrolytes more efficiently. You’ve probably seen it in airports, gyms, or even on social media, because it’s marketed as a quick and convenient way to beat dehydration from workouts, travel, heat, or long workdays.
At its core, Liquid I.V. is built around a simple idea: give the body the right ratio of sodium, glucose, and potassium so water gets absorbed faster. This is the same science behind oral rehydration solutions used in medical settings. Their main formula includes electrolytes, some B vitamins, vitamin C, and real cane sugar. Unlike brands that go sugar-free, Liquid I.V. actually uses sugar on purpose, because glucose helps speed up hydration — but this also means the drink is sweeter and has more calories compared to zero-sugar hydration mixes.
Liquid I.V. comes in single-serve sticks that you mix with water, making it super convenient when you’re on the go. They’ve expanded beyond hydration too: the brand now has Energizer mixes (with caffeine), Immune Support blends, and Sleep formulations. Even with this expansion, the Hydration Multiplier remains the star — it’s their bestselling product and the one people rely on for fast hydration.
From experience, Liquid I.V. feels like a “quick-fix hydration boost.” It’s great when you’re exhausted after a hot day or recovering from heavy sweating. The flavors are bold and sweet, and the hydration kick is noticeable fairly quickly. It’s not as “clean label” as some newer brands, but if you need rapid hydration and don’t mind sugar, Liquid I.V. definitely works and is widely trusted.
Key Differences:
Ingredients
When you compare TruLabs Hydrate and Liquid I.V. Hydration Multiplier, the biggest differences show up in their ingredient lists and overall formulation strategy. TruLabs takes a clean-label approach, focusing on balanced electrolytes and vitamins without adding sugar, artificial flavors, or synthetic sweeteners. Their Hydrate formula delivers a total of 1082 mg of electrolytes per stick, including 380 mg sodium, 580 mg chloride, 83 mg potassium, 30 mg calcium, and 9 mg magnesium. It also includes 19 vitamins and minerals, giving it more of a “hydration + micronutrient support” feel. For sweetness, TruLabs uses monk fruit extract and Reb M, which gives the drink a light, natural sweetness without adding calories or spiking blood sugar.
Liquid I.V., on the other hand, follows an Oral Rehydration Solution (ORS) model based on the science of fast water absorption. Instead of going sugar-free, Liquid I.V. uses cane sugar and dextrose, because the combination of sodium + glucose helps pull water into your bloodstream more efficiently. Their blend also includes potassium and a supporting vitamin mix of B3, B5, B6, B12, and Vitamin C. While Liquid I.V. does not emphasize the total electrolyte count on its ingredient page, most sources show that each stick contains roughly 510 mg sodium and 370–390 mg potassium, making it one of the more sodium-heavy hydration mixes on the market.
The calorie difference between the two is also noticeable. TruLabs Hydrate has only 5 calories per stick, making it appealing if you prefer a clean, low-calorie hydration boost. In contrast, Liquid I.V. averages around 50 calories per serving because of the added sugar. This isn’t necessarily a downside — it’s part of what helps the product hydrate faster — but it does make it a different experience compared to a sugar-free formula.
Overall, the ingredient philosophy between the two brands is very different. TruLabs prioritizes clean ingredients, full-spectrum electrolytes, and vitamins, making it a great daily hydration option for people who want something light and natural. Liquid I.V. prioritizes rapid hydration using sodium + glucose, making it more suitable for intense dehydration, long workouts, heat exposure, or travel when you need quick absorption.
Nutrition: TruLabs vs Liquid I.V.
When you compare the nutrition profiles of TruLabs Hydrate and Liquid I.V. Lemon Lime Hydration Multiplier, the difference in their overall approach becomes very clear. TruLabs Hydrate is designed to be a clean, low-calorie, sugar-free hydration mix. Each stick has only 5 calories, and the formula delivers a strong 1,422 mg of total electrolytes, including 500 mg sodium, 800 mg chloride, 83 mg potassium, 30 mg calcium, and 9 mg magnesium. On top of the electrolyte blend, TruLabs includes 19 vitamins and minerals such as B1, B2, B3, B5, B6, and B12. The brand avoids added sugars and instead uses monk fruit and Reb M, which gives the drink a naturally light sweetness without increasing calories or carbohydrates. Their formula is also free from dairy, gluten, soy, and artificial ingredients, making it a very clean daily hydration option.
Liquid I.V. takes a different route with its Lemon Lime Hydration Multiplier, focusing on hydration speed rather than being sugar-free. Each stick contains 45 calories, most of which come from its 11 grams of carbs and 11 grams of added sugar. This sugar isn’t just for taste — Liquid I.V. uses glucose on purpose to help enhance water absorption using its Cellular Transport Technology. In terms of electrolytes, it provides 500 mg sodium and 370 mg potassium, which makes it a strong sodium-glucose hydration formula. Liquid I.V. also includes a noticeable dose of vitamins, including Vitamin C (73 mg) and high-potency B vitamins like B3, B5, B6, and B12, with many exceeding 100% of the daily recommended value.
Overall, the nutritional difference comes down to your priorities. TruLabs is the cleaner, low-calorie, sugar-free option, making it great for everyday hydration without added carbs or sweetness. Liquid I.V. is built for rapid hydration, especially when you’re dehydrated from heat, travel, or intense workouts, but it does come with more sugar and calories. Both serve very different needs, and understanding this helps you choose the one that fits your lifestyle best.

Price: TruLabs vs Liquid I.V.

A 16-stick pack of TruLabs Hydrate costs $24.99, which breaks down to about $1.56 per stick. They also offer their “Hydrate Original” smaller pack at $9.99, mainly for customers who want to test the formula before committing to a full box.
Liquid I.V., on the other hand, is priced a bit higher. A 16-stick Hydration Multiplier pack costs $27.99 on their official website — around $1.75 per stick. Larger 30-stick packs sold through major retailers like Walmart run about $42.97, which still comes to roughly $1.43 per stick, but only if you buy in bulk.

Final Winner (Personal Take)
If I’m being completely honest and speaking from personal experience, TruLabs edges out as the winner for me — and it’s mainly because it fits into my everyday life more naturally.
Whenever I use hydration mixes regularly, I don’t want something loaded with sugar or calories. That’s where TruLabs just feels better. It’s light, clean, and doesn’t give me that “sweet overload” that I sometimes get with Liquid I.V. The monk fruit sweetness is subtle, and I don’t feel guilty using it two or even three times a day on busy or sweaty days. Plus, knowing it’s sugar-free and still packs over 1,400 mg of electrolytes gives me peace of mind that I’m actually replenishing well — not just drinking flavored sugar water.
Liquid I.V., though, is something I still keep in my bag. And honestly, when I’m really dehydrated — after a long run, heavy workout, or even a rough travel day — Liquid I.V. hits harder and faster. You can actually feel the hydration kick in because of the sodium–glucose combo. But the sweetness can be a bit much for me if I drink it daily, and the 11 grams of sugar per stick is not something I want to rely on regularly.
