Costco has a bag of Liquid IV right now—30 packets for $28 or $29, so I grabbed one. All are passion fruit flavor. The ingredient list looks good, not really any artificial junk added (flavors, colors, sweeteners, etc) which I thought was a plus. I tried the first packet on Friday, and while the fruity flavor was quite good, I thought it was very salty, so I was a little disappointed. I tried the second packet after hiking on Sunday, and it did not seem to be salty at all, and it got rid of the post-hike, slightly dehydrated, headache I had. My opinion of the drink was greatly improved after the second packet. I used the same amount of water both times, so I’m not sure why there was such a taste difference to me, but I’m hoping that first packet was a fluke. One possibility was I tried the first one at the same time I was eating a bunch of chocolate, so maybe that affected the flavor. Assuming no other weird taste issues with the rest of the bag, I’ll buy more because I think they are more effective than the Nuun tablets I’ve been using.
