Our verdict
When summer heat leaves you drained, plain water isn't enough — LMNT replaces what you actually sweat out, without the sugar. For active days, workouts and recovery, it's a simple, effective hydration upgrade.
The short version
Plain water doesn't replace the sodium, potassium and magnesium you lose sweating in the summer heat — that's where the headaches and sluggishness come from. LMNT packs a hefty dose of electrolytes with no sugar and no junk, so you actually rehydrate. Drop a stick in your water before a hot day, a workout, or the morning after, and you feel the difference.

Why not just drink water?
Sweating depletes electrolytes like sodium and potassium that plain water doesn't replace — which is what leaves you headachy and drained. LMNT puts them back.
Is there sugar in it?
No — it's sugar-free, which is a big part of the appeal versus traditional sports drinks.
Does it taste salty?
It's saltier than a sugary sports drink because the electrolyte dose is high; most people adjust quickly and pick a favorite flavor.
When should I use it?
Before or after heat, exercise, sauna sessions, or a night out — any time you've sweated or need to rehydrate properly.
