The short answer
LMNT is the sugar-free, high-sodium option, with 1,000 mg of sodium and 200 mg of potassium per stick plus magnesium, popular with heavy sweaters, low-carb eaters and people who fast. Liquid I.V. has less sodium, adds B vitamins and vitamin C, and its original formula contains sugar, which some people prefer for taste or long sessions. If you have high blood pressure or kidney issues, check with your doctor before using either regularly.

Frequently asked questions
Is Liquid I.V. worth it?
It can be handy for travel, hot days, long workouts or heavy sweating, and the added vitamins appeal to some people. For an ordinary day, water and food usually cover your electrolyte needs, and the original formula adds sugar. Compare price per serving with how often you'd really use it.
What's better than Liquid I.V.?
It depends on what you want. If you'd like no sugar and more sodium, LMNT is a popular alternative. If you just need everyday hydration and aren't sweating much, plain water is usually enough.
Do electrolytes break a fast?
Sugar-free electrolytes like LMNT are generally considered fasting-friendly because they have no sugar. Liquid I.V.'s original formula contains sugar, so it will break a fast.
Can you drink electrolytes every day?
Most healthy adults can, as long as total sodium stays reasonable for their activity level. LMNT's 1,000 mg of sodium per stick is a lot if you aren't sweating much. People with high blood pressure, heart or kidney issues should ask their doctor first.
