This post is in partnership with Hiya. I only endorse products I believe in.
Every morning, I drink electrolytes before anything else. Before coffee, before breakfast, sometimes even before I check my phone. It’s become a small but powerful ritual that helps me stay energized and clear-headed all day. So naturally, I started wondering: should my kids be doing the same?
They’re constantly on the move, especially in warmer months. But like most kids, they forget to drink water. So I did what most moms do when we’re not sure… I researched.
Can I give them the same electrolyte packets I use? Or is there something better, safer, and made just for them?
Here’s what I found when I compared the kid-formulated Hiya Kids Hydration to LMNT. Spoiler: there’s a clear winner for little bodies. And bonus that it's offered as a subscription model so you can set it and forget it and know you'll always be stocked.

Criteria #3: Taste
Hiya
It has a light berry flavor that’s not too sweet, but definitely passes as “juice” for my kids. They ask for it daily and I keep a few packets for them in my bags at all times (which is why the subscription model Hiya offers is amazing. Refill packs every 30 days? Yes, please.).
LMNT
If you’ve tasted LMNT you know it's for salt lovers, and even then it's very salty. While I personally love the taste, my husband can’t swallow it, and my kids yelled “YUCK” and spit it out all over my counter.
Taste Winner: Hiya
