I decided to give them a try. IDK why I guess I was just curious.

The Magnesium they use in Saltt is magnesium chloride which has a higher likelihood of laxative effect. I've had this happen to me.

LMNT uses Magnesium Malate which is supposedly helpful for muscle soreness? IDK on this for sure but google says so.

LMNT flavors taste better.

Also like the fact that LMNT gives you their basic recipe they use on their website as well if you want to mix up their electrolyte recipe yourself.
