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.

  • It definitely gets the job done! I get dehydrated pretty easily and when I do it's nice to have these on-hand. Like others have noted, however, they are VERY sweet. I've remedied this by only using half of the packet, and it works just as fine. As a note to potential buyers, though: do not drink this every day but rather as-needed. As it is an electrolyte supplement, it has a high sodium content by design and can stress out your kidneys if taken in excess. Not a doctor, just a conscious consumer. Still, it is a very good product and is perfect for those who struggle with dehydration like me.

  • Love the liquid IV products. All of the flavors are great and never taste artificial. Typically I'll dilute it to about half the suggested strength to avoid it tasting too syrupy. I usually buy the larger packs and then will use them for everything from a night out to long travel recovery.

  • Liquid IV is on an automatic shipment into my mailbox for two flavors: cotton candy and strawberry. While I love all of the flavors (except guava) these two flavors are amazing. The instructions are to mix into 16 ounces of water, but I prefer about 20 ounces so it is not as sweet. I keep a bag of the packets with me at work, and I also carry two or three in my bag just in case. These come in handy when I am dragging trough the day and sluggish. Sometimes a quick hydration boost helps to perk me up. The automatic shipment provides a great discount and free shipping, but Costco also has good sales on select flavors of Liquid IV a few times per year.

  • Tasty, easy to carry in my purse and mixes well. I enjoy the fresh, not too sweet flavor. Easy to add to my water bottle before a long walk in the Arizona heat and keeps me from feeling lightheaded with low blood sugar or dehydration headache. I nice change from plain water. Will try the Golden Cherry next.

  • Liquid I.V. Adult and kids is a quick electrolyte powder pack to be dissolved in water. It does contain stevia a silicone dioxide, if you’re concerned about either one. Otherwise it works fast and we use it when practicing for marathons.

  • Personally I am not a huge fan of Liquid I.V. and its nutrient profile. Its not that it is bad per say, I just think it leans on the expensive side for electrolyte drinks (I am willing to pay more for a quality drink) but honestly I think there are products out there that are the same price if not cheeper and have more of the electrolytes I am looking for as a distance runner.

  • I am writing a new review for this brand as I have recently discovered an option that doesn't have the thick taste I felt a majority of these powders have. The kids' version tastes a lot better and has a lower sodium content. For me, this is a win-win, as I need to watch my sodium intake for health reasons but also sometimes need the electrolytes after working out or other physically active days.

  • I love this brand because it offers a way to help me to stay hydrated while having a great-tasting drink. I like that the brand offers multiple different types such as a variation that adds immunity support. These are pretty expensive, but I think it's worth it because these always work.

  • This is my go-to hangover helper. The lemon-lime is my favorite flavor. **Editing 2023, This used to be my go-to hangover helper but I realised how much sugar was in each packet. I have now switched over to Waterboy. Liquid IV works, but in my opinion Waterboy works better & faster.

  • I love Liquid IV. I received a sample in a GQ box and pretty much tried every flavor. The limited editions and sugar free items are top notch. The immunity ones are good too. If you are okay with added sugar the cherry, grape, and passion fruit are all recommended.

    Are all electrolyte brands the same? I tried 7 brands to find out.

  • I wish Liquid IV didn't use stevia/low-calorie sweetners. As someone who avoids those kind of ingredients it saddens me that I can no longer consume this product. The sticks are small and easy to transport for on-the-go hydration. If the ingredients were different this would be my go-to brand.

    Received a free product from Liquid I.V.
  • Super effective + easy to use on the-go (thanks to the single sachet packs!). The flavours are pretty good and true to naming i.e. critic flavours are critic forward and not too salty. The pricing is pretty standard for running-related hydration packs, but I definitely plan to sign up for the subscription to save $$$ when I hit peak training season.

  • Taste is great but they really mess up my stomach (assuming it is the amount of Stevia used in this) I would keep that in mind if you try these and you don't feel great. If they don't though, passionfruit I think is the best flavor in the lineup

  • I'm kind of indifferent about LiquidIV, I find it a bit pricy compared to other options, and while I don't really know the efficacy compared to others, my struggle with LiquidIV is the intensity of the sweetness. I can barely finish a packet in a huge glass of water so I often only have half a packet, or I have to drink two giant cups of water (I guess this isnt the worst thing lol) Flavours are nice, I like the Golden Cherry and Passionfruit and we only ever buy them in the big bag from Costco (In canada) or out and about on vacation.

  • Have been using these for years. They are great to keep in a workout bag or a backpack for long hikes. Because it is in a dry pack, it's easier than taking along a bottle of Gatorade or something. Please, please, please read the label though and only drink the recommended amount, as too much or too frequently can be hazardous.

  • I don’t go without! I drink 1 a day. It’s great for someone who works out, or someone like me who has mad migraines & autoimmune issues… along with absorption issues with vitamins due to an autoimmune disease in my stomach. This brand has saved me! Through the flu, migraines, etc. I’m so grateful for this product. I absolutely love the cotton candy flavor & watermelon, although they are all tasty! Sugar free is likely best for me but I prefer the sugar. Reasonably priced on the website, ships fast, customer service is FANTASTIC, & worth the price. I drink it daily but if you are not like me, a little goes a long way.

  • I resisted trying Liquid IV for a long time because I really enjoy some of their competitors, and the price felt a little high comparably. However, I just moved down to Austin, and in the heat, you kind of need all the help you can get with hydration. A few fitness influencers I follow love the brand so I decided to give the watermelon flavor a try. I really actually love the product- it dissolves easily, the flavor is good, and you can immediately feel the impact- whether you have been in the heat, are feeling hungover, or just want some precautionary hydration!

    Feedback

    As recommended by some influencers, I only use HALF a packet in a glass of ice water at a time- this cuts the sweetness and makes the flavor light and enjoyable. Again, my only other qualm about this brand right now is the price point which is about double that of some of their competitors (like Nuun) and its hard for me to tell a substantial difference.

  • LiquidIV is still my favorite endurance electrolyte supplement if I know I'm going to be in the heat, whether I'm cycling or hiking. 1 packet is enough for my two-liter hydration bladder, and I still prefer it over the other competitors in this space. My only complaint is that I wish they offered a lower-sugar option. The flavors are great, and I LOVE how potent the singular packets are. I absolutely recommend that you dilute it in a larger volume of water.

  • My husband and I love liquid IV! There are so many delicious flavors that we have tried. There have been a few flavors we didn’t like but that’s personal preference. It keeps us super hydrated which is amazing!

  • Oh my god this are good n the ones for kids are amazing.. the different taste as well.. I like that my son stay hydrated while been in school
