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.

  • Not super into the flavor of these…reminds me of melted jello or medicine. Would rather just drink water.

  • I love packets over bottled electrolyte drinks! It is a more sustainable option and easier for on-the-go travel. My favorite flavors are the tried and true lemon lime and acai berry! I also love using these because the sugar content is lower than alternative electrolyte drinks!

  • Good flavors and always coming out with seasonal flavors so keeps it interesting. Mainly use them after a night out.

  • Very sugary, but extremely effective and tasty. A must-have before a night out. Buy now and thank yourself later.

    Lower sugar option

  • This was highly recommended when my toddler wouldn't drink the other brands. They have good flavor options, and my son liked it diluted a bit.

  • as a middle aged mom i was advised to use this when i went away with a group of college kids. i wanted to drink but didn't want to feel hung over the next morning. I popped one of these before bed and i woke up feeling great the next morning where i would have otherwise been hung over. They also taste really good. I also used them when i felt like i hadn't' drank enough water. They were great for preventing hangovers but they're pricy, for regular electrolyte usage i would just buy propel or something similar

    The price

  • I bought a Costco size box of the Liquid I.V. And although I finished the whole box, I found them to be overly sweet/salty. I actually looked at the ingredients and there was so much sodium in a serving size that I found myself swollen after drinking them.

    Feedback

    Great concept + packaging. Tasty enough to make me drink more water, but not worth the calories and sodium.

  • I love drinking these after a night out or before drinking in the sun! They help prevent dehydration + headaches for me personally

    Nothing

  • I drink these every time before I go out drinking and the morning after. I got the giant pack at Costco. I'm not sure how effective they actually are. It's the fact I'm just drinking more water or a placebo. I figure it doesn't hurt to drink them and they don't taste very bad.

    They're good but extremely sweet. I think if you don't drink often they aren't worth it and you'd be better off going with a Pedialyte though.

  • Great concept, its been super helpful for non-alcohol-related sicknesses like the flu or food poisoning. I believe they have ones specifically for energy too like matcha and great for when you're out in the sun all day!

    I have learned to not drink this specifically to avoid hangovers... I would have a glass of water + pineapple liquid IV 30 minutes before drinking and I threw it all up the same night with the salty powdery aftertaste lingering in my mouth. Another time, I woke up with a hangover and drank a glass of liquid IV, and threw it up before I could even feel relieved of the pain.

  • I like the concept, but the powder smells linger in the air a long time

  • Finally I can feel hydrated. I suck at drinking water regularly so this product is great.

    Feedback

    I had the watermelon flavor and it did not taste like watermelon, rather it tasted like the outside of a watermelon.

  • Not a fan of the flavors but it does help with hydration. Also available almost everywhere so that’s also convenient.

  • Very sugary but a great way to rehydrate after a big workout. Watermelon is a great flavor!

  • I use liquid IVs religiously because i never drink water and it helps so much.

    Feedback

    I wish they tasted a little better

  • A nice boost to my drinks - still have more flavors to try. Nice to be able to have these on hand and add to water versus stocking up other similar products.

    Feedback

    I find the flavors to be very strong - I often double the water for my mixes . A little less sugar would be preferred

  • Mid - not great doesn't suck - It does what it says it does but it's not the best not the market. Super great marketing tho for how good everyone thinks it is

  • It works! If I'm feeling dehydrated or have a headache, I'll drink one of these and genuinely feel better in an hour. Is it a unique rehydration packet? Not really, but I'll continue to buy these.

  • Love that these are easy to find and definitely do help when feeling dehydrated. A lot of the flavors I strongly dislike, the lemon lime is the only one that I actually enjoy. The other flavors are super artificial-tasting.

    Simple flavor options and less sugar! The sugar content is absolutely insane.
