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 great, but there’s better alternatives out there with cleaner ingredients and more effective

  • Love the brand and their mission! Flavors are 10/10 and keep you hydrated!

    Works for Liquid I.V.
  • I used the ginger/matcha energy flavor and it tasted like a lemon lime Gatorade. It was great, clean energy that didn’t make me crash and Costco has great bulk deals on them as well. Convenient ready to go packs make them easy to stuff everywhere and have them handy whenever you need a little boost. Mixes well with room temp and cold water but will settle if left alone for a while.

  • Good taste, expensive and lot of sugar

  • I did prefer the taste of Liquid I.V. over competitors as it was slightly saltier, which I liked rather than an overly sweet drink. That said, I was relying on these to get extra hydration during my third trimester and did not realize how much sodium was in one packet/serving. Explains the salty taste! If you have pre-eclampsia, high blood pressure or any other conditions where sodium levels affect your health it might be safer to consume way less than the recommended daily amount or use other water enhancers with less sodium.

  • Great product. Always helps to take it before bed after a night of drinking or before a hard workout. It's a little sweet, but still tastes great if you dilute it with more water. Also the single serves make it easy to take on the go!

  • This gives me the motivation to drink more fluids during the day. My personal favorite is the Strawberry one

  • Flavors have all been good. Lemon lime is too salty, but other than that, no complaints. Easier to drink than water when dehydrated and works much faster.

  • Haven't really noticed a super hydration difference but the taste is nice, albeit a bit too sweet for me so I water it down a bit more than recommended. Very easy to take along in your purse or backpack. Great for traveling.

  • They’re really yummy and a nice flavor when you get sick of drinking plain water, lol. I would drink these before going out/ the morning after a night out and they always seemed to help!

  • The hangover cure.

    Friends with Liquid I.V.
  • The first time I tried the liquid IV was with my friend in Costco. We tried out the tangerine flavor and instantly fell in love. It tasted too good and provided extra hydration and vitamin c? Count me in. Ever since i’ve had a bag of 30 and I use them for trips, the gym, hikes, anywhere i’d need a boost. Loveeee u liquid iv!!

  • While I love the idea of boosting my hydration with a single portable packet, I find the taste to be a bit off putting and simultaneously too sweet yet too salty. With 11g of added sugar, I think there are other competitors that taste better without having as much added sugar.

  • Helpful for when you are sick or dehydrated. It does have quite a bit of sugar.

  • Liquid IV is the BEST! I have yet to meet a flavor I don’t love. Normally I would use these after a night of drinking to bring me back to life, but I’ve added these into my normal routine nowadays. I’m a new mom, so staying hydrating is sometimes tough with a little one. I do wish these were cheaper, but they are tasty, and make you feel great, healthy, and hydrated! This reminds me - I gotta stock up 👏🏻

  • You know those days when you feel a headache on the way— then you remember you haven’t drank any water at all in the last 24 hours… These are lifesavers for those instances! I just rip open a packet and add it to my water and usually within about 30 minutes of finishing my water my headache is starting to go away with the use of Tylenol. Amazing! I also pack them on long hikes or for a workout. I honestly think every flavor they’ve came out with is delicious too!

  • Unfortunately, I get very bad hangovers. This is the only product that helps my hangovers when I prepare properly. It’s light and easy to drink.
