The category benchmark, and the reason people fall down the electrolyte rabbit hole. LMNT puts 1,000 mg of sodium in a stick — the top of the range that actually matters for hard training or heavy sweating — with zero sugar. That high sodium is exactly why it wins here and also why it isn't for everyone: if you're lightly active it's more salt than you need. At about $1.50 a serving it's premium, and the taste is polarising (it is, unapologetically, salty).
1,000 mg sodium, 200 mg potassium and 60 mg magnesium per stick, all stated plainly, no sugar and no proprietary blend. The number that earns the score is sodium: most 'hydration' powders sit at 200–500 mg, so they're flavour with a pinch of salt. This is the opposite — plenty of sodium, which is the point, but respect it.
Made for heavy sweaters, long or hot sessions, fasting, or anyone told to raise their sodium. If you're at a desk and just want a nicer water, it's overkill — a lower-sodium option like Nuun fits better.
