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.

  • This product has saved me more times than I'd care to admit. The harsh reality of hangovers after 30 have slowed down my alcohol intake dramatically but when I do want to have a night out I make sure the liquid IV is stocked.

  • I bought these to take to our destination wedding. They helped a few friends recover. Some from upset stomachs & one from the party the night before. I didn’t personally live the flavor, but my friends sure appreciated them.

    Feedback

    Very good for recovering from a stomach bug or hangover. The flavor could have been better for my liking.

  • Great hydration! I have only tried the watermelon flavour but was spot on… just slightly too sweet for my liking and not a fan of natural flavours.

  • These are great, and as a migraine sufferer, a real lifesaver. I bring these everywhere, and even let my son drink some now and then. Easy to pack in a bag for a flight, or any travel.

    Feedback

    I would like a less sweet flavor...like a half sweetened version.

  • incredible for helping with unnecessary hangovers in my personal opinion. these are a total game changer.

  • Noticeably great re-hydration! I don't use it often but when I do, it's almost always a "wow, these work" moment, and the whole fam agrees! Saw some reviews pointing at the higher sugar and lower electrolyte levels compared to competitors... the formula liquid IV uses is meant to deliver hydration and nutrients to the system faster, and the sugar + sodium concentrations are a part of that formula. Copy-cats came in and said let's strip the sugar and 5x the electrolytes without paying attention to the "how?", a pretty standard copycat practice in CPG. Reminds me of a brand that used a digestive enzyme in their gut relief capsules (which worked very well), and within a couple of years, copy-cats popped up stating they used 5(!) digestive enzymes and were better because of that reason, without talking about efficacy at all 😂

  • Life saving hangover cure!! I wouldn't recommend the matcha flavor but that's my only complaint overall.

  • This is great. Very comparable to Pedialyte, but I would say the flavors are much better. These are VERY flavorful, so I would suggest combining with more water than they suggest (unless you like it really loud).

  • I LOVE Liquid IV! I buy them in bulk from Costco which saves on per use cost. These little packets are so handy for traveling, hiking, and high heat environments. When I travel, I drink a packet each morning before coffee, and feel the travel grogginess disappear. I drink a lot of water, and am not usually a fan of sweet drinks but this is the best hydration supplement/drink out there. It's a must have for me!

    Feedback

    It can be a little salty/sweet, but I just mix it in a much larger quantity of water and it's perfect for me.

  • Wanted love it but its such a high price and sugar content. I'll just dump some salt in some water.

    Feedback

    Step back on the marketing and lower the price and sugar content.

  • I love LiquidIV, they taste great and seem to work really well. I feel better almost immediately after drinking one of these.

    Feedback

    Perhaps lower sugar content, otherwise these are perfect.

  • I love Liquid IV for a long time, it's saved me when exercising a ton in the heat and surfing and when I was hungover. I don't love the amount of sugar in it - I prefer LMNT - they have way less sugar (very salty though, but salt is good for you!) and cost less overall

    Feedback

    I have celiac, and so does my sister. My sister recently sent me a video of liquid IV being tested for gluten, and despite the label saying "gluten free" certain flavors for sure have gluten. Once I saw this video - a whole bunch of stomach aches, which I had attributed with eating at restaurants and bad preparation containing gluten made sense.

  • The best thing about liquid IV is that it tastes so good, you want to drink more water. The sugar content is a bit high for me to commit to this product long-term. I also think you can split each packet in half, the flavor is SO strong. In terms of extra hydration, it seems to do the trick, just watch out for the sugar. There are other options out there with a bit better ingredients it seems.

  • As an electrolyte and hydration solution this gets the job done. I think the flavors are just ok and the packets are actually almost too large. I prefer Nuun for their flavors as well as the size of the tablet and the ease of transport

    Feedback

    These are super expensive compared to Nuun. Nuun also has other added beenfits like caffiene or vitamin C - that could be worthwhile here

  • I've been using Liquid I.V. for the last 3 years and think it i a great alternative to gatorade and perfect for when traveling. I like to have a pack with me at all times in case I'm feeling dehydrated.

    Feedback

    Variety packs would be a fun alternative

  • Liquid IV dissolves so well into water. We have tried multiple flavors and liked them all. Makes drinking water much easier.

    Feedback

    A better way to package product with less waste.

  • Amazing flavors, but they are on something if they think you need to put one of these in a 16oz container. Only if you want to immediately pass out. These are POWERFUL. I put one in my 40oz Stanley and that's the only way I can drink these

    Feedback

    Maybe sell a product that is 32 smaller packets instead of 16 bigger ones. Bring back the pear flavor!

  • Great for portable hydration.

    Feedback

    It's rather expensive and the taste is very sweet (the first ingredient is sugar).

  • Super delicious and soo many flavors. We use liquid iv for soo many occasions - working out, hangovers, aha when sick. So great to have these on hand.
