Liquid I.V. reviews and discussion

Reviews mention

  • Noticeably fast hydration boost
  • Convenient travel-ready packets
  • Wide, crowd-pleasing flavors
  • Mixes easily in cold water
  • Overly sweet, sometimes salty taste
  • High sugar and sodium content
  • Occasional thick, gritty texture
  • Inconsistent flavor enjoyment

Liquid I.V. earns strong reviews for fast, noticeable hydration—especially after workouts, travel, heat, and hangovers—while convenient single-serve packets and broad flavor variety (Lemon Lime, Strawberry, Passion Fruit, Watermelon, Golden Cherry) stand out. However, many reviews flag overly sweet, sometimes salty flavors, a “thick” mouthfeel, undissolved grit, and high sugar/sodium; some prefer diluting with more water or the newer sugar‑free line, and a few question ingredient “cleanliness” or effectiveness versus competitors.

  • I really love this as a supplement to my workouts. Makes me feel less fatigued, especially if I'm working out outside in the summer. Quick and easy way to replenish my electrolytes and keep the workout going!

  • Liquid IV is a go-to for me when traveling. It helps me stay hydrated and stave off a flying headache that I often get when traveling longer distances. I also use the Immunity variety when I feel a cold coming on or have a cold. The flavors are decent enough.

    Feedback

    Prices range wildly between grocery stores, online, and wholesalers like Costco. Costco is generally much cheaper and you can usually snag the immunity blend there as well.

  • 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.

    Feedback

    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.

    Feedback

    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.

    Feedback

    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!!!
