Reviews mention

  • Fast-acting hydration boost
  • Convenient travel-friendly packets
  • Wide, crowd-pleasing flavors
  • Smooth, easy dissolving powder
  • Overly sweet flavor profiles
  • Noticeable salty aftertaste
  • High sugar and sodium content
  • Occasional clumping texture

Liquid I.V. earns strong reviews for fast, noticeable hydration—especially after workouts, heat, travel, or a night out—while convenient single-serve packets and broad flavor variety (standouts include Lemon Lime, Strawberry, Passion Fruit, Watermelon, Golden Cherry) make it easy to use. Reviews also flag consistent drawbacks: many flavors taste overly sweet or salty, some feel thick or artificial, and the added sugar and sodium (with a newer sugar‑free line noted) are frequent concerns; mixing can clump and flavor hit-or-miss. Overall, the brand is effective but polarizing on taste and ingredients.

  • I love the different flavors they offer, and how quickly I can feel rehydrated again. I often have a Liquid IV after exercise on hot days (or when hungover) and I think it really does save my hydration. The flavors are excellent as well - Lemon Lime is my favorite.

    I’m not a well hydrated person. I’m not a fan of water either and often in the summer I get headaches from being dehydrated. I use Liquid IV to bounce back. I’m not a fan of the taste or the artificial sweeteners but it does do the trick and I do feel better. I keep the packets on hand for nights that I get a leg cramp and days that I get a headache.

  • LiquidIV is one of my favorite products and I always have packets on hand at home, on the go, and especially when I travel. Every single flavor I have tried has been tasty and I love trying the specialty flavors they sometimes release on their website, like Pina Colada or Strawberry. I notice that I feel more hydrated after drinking one of these electrolyte packets because I am more alert and notice that I am not as thirsty. Definitely recommend!

  • Avid user of this - great for post-drinking nights, right before bed. I do wish that they would come out with a version with no added sugars.

  • My go-to hydration fix! I love the pina colada flavor. Usually, other hydration mixes make my stomach hurt, presumably due to the artificial sweeteners but I have no problems with this one. One downside is that it is more expensive per stick than competitors but I think it's worth the extra money.

  • friend brought these to vegas. Really tried to like them but simply could not drink it. The flavors are interesting but I just could not stomach the taste.

    Tastes bad :( Love the concept though

  • A must have! After experiencing a few long weekends with drinking Liquid IV has helped me rehydrate. the taste is a little salty though

    Feedback

    pricey - salty taste

  • Overall great tasting product. Flavors are fund and exciting. Hard to tell if the effect that they advertise are really working. Even between the energy and other types.

    Wish this was cheaper.

  • Good in a pinch, the flavor are good

    Feedback

    pretty high in sugar and if you can stomach it a shot of pickle of juice will do you way better for mitigating a hangover

  • I don't like how this markets itself as healthy. It has 11grams of sugar in one packet!! I've never been able to drink an entire packet in one sitting, and diffuse probably like 1/3 of it in a large container of water. I just don't think it needs that much sugar. It gives me a stomach ache.

    Less sugar

  • Great flavors and I feel like it worked! I use these when I'm traveling or for hangovers.

  • So yummy and (although I don’t know whether or not this is a placebo effect) you can feel the extra hydration. 10/10. My friend mixes it with her vodka to ward off hangovers.

  • Life saver in every scenario. Hang-over prevention. Hang-over cure. They should sponsor MBA programs and Coachella at this point. It helps that every flavor tastes great and you can carry them in a fanny pack.

  • Love these for anytime I'm feeling dehydrated or in need of an electrolyte pick-me-up. I've tried the watermelon flavor, it's really refreshing and enjoyable - no bad aftertaste.

    Feedback

    Price seems a little high for the value.

  • I have POTS or postural orthostatic tachycardia. Because of this I need extra electrolytes in my system, especially when I’m feeling a flare up. Liquid IV is honestly the best, in terms of finding relief from an easily accessible electrolyte product.

    Feedback

    It does have an intense taste, but I often split it between to servings of water or two water bottles. That way I’m getting even more water in my system as well as the liquid iv to help regulate my heart. Love liquid iv!!!

  • Been drinking these forever, and it does make a difference which is a win in my book. Also, they taste fantastic, are super accessible to purchase, and have continued to build upon their product offerings. However, it’s not a silver bullet solution and works best when combined with supplements with milk thistle.

    Feedback

    Continue adding new products that have more liver benefits beyond helping with dehydration.

  • Very practical but not necessarily innovative. We used these for a long festival in the desert. Lugging around giant bottles of Gatorade or other post night out hydration drinks is impractical. These packets when mixed with water did do the job of rehydrating us nicely. We used them several times. Some flavors were better then others. Definitely aim to mix with ice cold water. That helps with the taste. I wish they used less sugar overall.

    Feedback

    Less sugar please!

  • Great taste, and helps with a whole host of things ranging from sickness to hangover and more.
