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.

  • Big fan of the variety of flavors, like lemon lime, mandarin orange. They are very convenient to use and mix into cold water easily. I wish that there were more low sugar/sugar free options. Also there are some crazy flavors that are fun to try but do not taste good like hot cocoa.

  • These liquid IVs are so yummy and helpful with keeping myself hydrated. Especially when I’m traveling. I throw them in my bag so I can easily add it to my water bottle when I’m on the road. I can’t wait to try them all!

  • I like this flavor, but it’s not as good as the rainbow sherbet. I love that it’s sugar free and hydrating, and gets me to drink water when I’m having a day I don’t feel like plain water. It tastes 50/50 strawberry and watermelon.

  • My favorite flavor! Really tastes like rainbow sherbet, and I love that there’s no sugar. When you’re really dehydrated you do need the sugar, but for a day to day or people who cannot tolerate the additional sugar this is great!

  • Great flavor and super convenient. Great for overall hydration but also after a long night out or after any workout or strenuous activity. Super easy way to rapidly rehydrate. Use all the time when I travel

  • Not the most delicious electrolytes. Does taste a tad bit medicinal. But it might just be the flavor I got (raspberry melon). I’ll finish the box but I won’t order it again (or I’ll try the non-sugar free ones)

  • I am a big fan of liquid IV. I’m not an everyday user, but love to have them in the pantry for when I feel like it would benefit me (hot day, lots of exercise, beach day, day drinking). There’s some great flavors that I love and then others that I probably won’t get again. Also great that it’s so accessible - I get them at my grocery store, CVS, Costco, etc

  • I strongly strongly dislike the taste of salt. That's a big deal breaker on most of these electrolyte drinks. BUT the Cotton Candy flavor is my life saver! I refuse to run out of these and carry a few sticks in my car and backpack just in case. They are not overly sweet either which I love. I don't notice a difference in taste between pink and blue so that doesn't matter to me. I have these bad boys on subscription refill monthly that's how good they are!

  • Not my favorite electrolyte brand! I find both the regular and sugar free flavors to be entirely too sweet + artificial tasting. Quite expensive compared to other brands. However, it's nice that you can find these in most stores so I will buy out of convenience - these have saved me while traveling!

  • The least salt of all electrolyte mixes I've tried! They have a great range of flavors so not matter if you like something sweeter or less sweet, you'll be able to find something that fits your taste.

  • Liquid I.V. has definitely helped on the days I haven’t kept up with water or feel drained from travel or being out in the heat. It works quickly and I actually notice the difference. Some flavors are a little too sweet for me, and it’s not something I drink every day, but it’s great to have on hand when I need a boost.

  • I like Liquid IV for it's convenience but I will admit there is quite a lot of sugar in the regular ones. I've also tried the sugar-free but I am sensitive to the taste of artificial sweeteners so the aftertaste is a bit off-putting. I wish they made a lower sugar one! These are great to replenish electrolytes from a long day hiking or walking around in the sun at a concert or festival. I think there are much better options out there, but Liquid IV is one of the most available brands sold everywhere now, so it's more accessible compared to some of my other favorites like Waterboy.

  • I have two teenagers who are very active and I was excited for them to try Liquid I.V. Unfortunately, neither my son nor daughter liked the taste. When I tried the various flavors, I had to agree with them. No matter the flavor, all I could taste was sodium. When I looked at the ingredients, I was shocked to see just how much sodium was in just one packet. Shame on me for not checking it first.

  • This stuff is SO stinking tasty. It doesn't leave any weird taste in my mouth. They are rather pricey though so you have to use sparingly, which I recommend anyway because too many electrolytes can mess with your kidneys. Costco is my go to spot to buy them!

  • This has been a go to during my pregnancy and postpartum. It always helps me quench my thirst. One packet also packed a lot of flavor, so it's perfect for my giant hydrojug to dilute down. I love all of their flavors especially with ice cold water.

  • This is a unique, sweet flavor that hydrates me after a long work night and I often don't drink as much water as I need to. Sometimes I feel these mix-ins are a bit over-prices, but I have tried knock-off brands and they don't make me feel as good as the original brand so there is definitely a difference in ingredients and taste! I am sticking with Liquid IV for sure for my hydration needs!!! p.s. Liquid IV is great to take to the pool and the beach too so you stay hydrated!!!!

  • I’ve tried many flavors of Liquid IV both sugared and sugar free. I did not care for the sugar free version. Grape, Strawberry, and Passion Fruit are my favorites. I tend to drink more water when I’m using Liquid-IV however it is my understanding that unless you’re sweating buckets it’s best not to use this as a flavor enhancer as your electrolytes can be thrown out of whack. It dissolves much easier than the tablet form of electrolytes. I drink it with my creatine supplement when working out.

  • Using LiquidIV is a game changer. In the summer temperatures and high heat, I often feel dehydrated and adding LiquidIV to my water is an instant change of how my body feels. I keep extras packets in my purse everywhere I go. And all the flavor choices gives a nice variety and change!

  • I like to add a package to my bottle water daily. It helps to keep me hydrated and the taste is great. It’s really refreshing and an easy way to get some essential vitamins. The packaging makes it convenient to take some on the go.

  • I bought these to help keep my daughter as hydrated as possible before she would go in for infusions at the children’s hospital for a bone disease. She would drink one pack the night before and one the morning of her infusion and it would make the IV placement go so smoothly. There had been times where it took 2 - 3 attempts and pretty stressful. Since adding Liquid IV it’s been a breeze. It’s a life saver and I will always have this in our kitchen!
