Liquid I.V. vs LMNT: which has more sodium and less sugar?

LMNT has double the sodium of Liquid I.V. One LMNT Citrus Salt stick has 1,000mg sodium, 200mg potassium, 60mg magnesium, 0g sugar and 5 calories. One Liquid I.V. Hydration Multiplier Lemon Lime stick has 500mg sodium, 370mg potassium, 11g sugar and 50 calories, with no magnesium listed on its label. Liquid I.V. Sugar-Free Lemon Lime keeps the 500mg sodium and 370mg potassium but drops sugar to 0g and calories to 20. So LMNT wins on sodium and magnesium, Liquid I.V. wins on potassium, and the original Liquid I.V. is the only one of the three with real sugar. LMNT is sweetened with stevia leaf extract (Raw Unflavored is unsweetened). Liquid I.V. Sugar-Free uses what the brand calls an allulose blend. All figures come from each brand's own nutrition labels.

Which is better for long or sweaty sessions?

LMNT, if you're a salty sweater, because 1,000mg is one of the biggest sodium doses you can get in a single stick. If you also want carbs on the move, the original Liquid I.V. gives you 11g sugar with its 500mg sodium. Some people use both: LMNT before a hot session, Liquid I.V. during. See salt for athletes for how sodium needs vary.

Which is better for everyday sipping?

For a regular day at a desk, Liquid I.V. Sugar-Free is the gentler pick: half the sodium of LMNT and 0g sugar. LMNT's own FAQ says many people find 1 to 2 sticks a day works, depending on activity. Two LMNT sticks is 2,000mg sodium, close to the 2,300mg Daily Value, so count it in your day.

If you follow a sodium-restricted diet or have blood pressure or kidney conditions, check with your doctor before using high-sodium mixes.

Taste and price notes

LMNT is noticeably salty by design. Liquid I.V. original tastes sweeter because of its 11g sugar. On the brands' own sites in Nov 2026, a 30-stick LMNT box was $45 one-time, and a 16-stick Liquid I.V. pouch was $24.99 one-time, both cheaper with subscriptions.
