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.

  • Tastes wonderful but I don't like the sugar alternative used.

    Received a free product from Liquid I.V.
  • I’ve found Liquid IV to be quite sweet, but it’s a great go to when I haven’t thought ahead and need to grab electrolytes from Whole Foods!

  • Liquid IV is one of my favorite tasting hydration drinks, probably because it's one of the only ones with real sugar in it. It's a little expensive for what it is though and sometimes you don't always want sugar in your drink

  • I use liquid IV at least 10 times a month. The flavors are absolutely amazing and heads above the other hydration multipliers on the market. The passion fruit is definitely the best, Concord grape is next in line.

  • Gross. This is an absolute NO. There is so much sugar in this product, don't be fooled!

  • I hate to admit that this works, but time and time again I feel like it's saved me. I'll slug this down after a night out and definitely feel like it curbs the next day hangover. Also makes drinking water easier since it's tastes pretty good. Knocking off a star since it's pretty expensive for essentially being sugar and salt in a packet but hey if it works it works

  • Used to purchase regularly, have switched over the LMNT after comparing the ingredients.

  • I have an outdoor job, which means some days I’m in 100°+ weather for 10 hours straight. It’s hard to keep hydrated when you’re melting into your neoprene waders with not a shade tree in sight. I heard about Liquid IV on a podcast ad, and got some to try. They’re really effective, and I don’t have to pack gallons of water in order to replenish my hydration while in the field. The electrolytes are a huge plus too, since I’m typically sweating buckets! I definitely notice that I don’t fatigue as quickly or get dry mouth if I’m sipping on Liquid IV while I work. It’s also clutch after a night of drinking— I pour one pouch into a tall glass of water, drink it before bed, and wake up feeling right as rain. The flavors are great too.

  • It works very well, and often a go-to for hangover prevention. Some flavors are better than others. My favorite flavor is the guava, strawberry, and the watermelon. I graded it "okay" because it's chock full of sugar, which is too bad.

    Would love to see a formula with lower sugar content.

  • Meh. Tried to take to avoid earth shattering hangovers on a bachelorette. Spread out to all ladies. Common consensus was : still feel like death… perhaps a wee bit less than we would have otherwise. Gatorade is cheaper

  • I cannot tell you the number of people I have evangelized about Liquid I.V. I love using this as a pick me up after a hot day or a hard workout. The tangerine flavor is incredible (plus vitamin c and zinc!), other standout flavors are strawberry and watermelon for a "sweeter" seeming flavor, and the guava is a nice more subtle flavor.

    The pack to water ratio is really off for me. I mix with at least 24-30 oz of water (extra extra hydration ;) ) since I don't like it as sweet, but that is perfect for me.

  • Great to use when you’re feeling dehydrated. The small packets are portable and great for on-the-go use. The flavor variety is great too. I do think some of the flavors are too salty, but that might just be the nature of electrolyte drinks.

  • It works! And tastes great. Always have these on hand when I’m planning to spend a night out.

  • Helps stay hydrated and makes you want to drink water. I add more water than the directions say because otherwise I think it’s too sweet/concentrated flavor. Helps me keep my electrolyte balance on hikes so my fingers don’t swell

    Lower the sugar content

  • The flavors are good, but I am curious to know if these actually work. I know some people swear by them, but when I tried them, I didn't feel like they 'replenished' me. Not the same glucose rush that gatorade gives, which feels good.

  • The best hangover cure, hands down! I was skeptical at first but after trying Liquid IV for the first time, I couldn't believe how much better I felt, almost instantly. They have pretty good flavors too!

    Feedback

    I'm not a huge fan of drinks like Gatorade because of the texture and this does remind me of a sports drink.

  • I'm not a fan and I'm honestly shocked how popular this product is.... It's way too sweet! (i.e. Tastes just like drinking candy.) I got such a upset stomach after using it. Although, I felt more "hydrated" because I had to drink so much water after how dry it made my mouth. So in essence... I guess it works? Would rather just chug a packet of stevia and have the same effect.

    Make the product less sweet and healthier.

  • I've drank Liquid IV after a long night out before, but the flavor is definitely not one I like. there are artificial sweeteners in it along with real sugar, but stevia has such a distinct taste that i can't get over. would i get this again if it was one of the only options for electrolytes? yes. but i wouldn't go out of my way to get it.
