LMNT vs Liquid I.V. Sugar-Free Labels: Sodium, Potassium, Sweeteners and Stick Size
The short answer: LMNT Citrus Salt and Liquid I.V. Hydration Multiplier Sugar-Free Lemon Lime are both zero-sugar electrolyte sticks, but the two labels are built very differently. By the printed panels, one LMNT stick lists twice the sodium of one Liquid I.V. stick, while the Liquid I.V. stick lists more potassium, five B vitamins and vitamin C, and weighs more than twice as much. Here is the side-by-side reading, line by line, as each brand prints it.
How we wrote this: the figures come from the Nutrition Facts images on each brand’s own product page, viewed in October 2026: the LMNT Citrus Salt panel and the Liquid I.V. Sugar-Free Lemon Lime panel. The Liquid I.V. ingredient list and mixing note come from its product page; the LMNT list is printed on its panel image. We have not tested either product, a box in a store may differ from the web image, and this is not diet or medical advice. For how each line of an electrolyte panel works in general, read our electrolyte drink mix label guide; this page only compares the two labels.
Both are Nutrition Facts panels
Neither stick carries a Supplement Facts panel. Both images read “Nutrition Facts”, so both are labeled as foods under 21 CFR 101.9. That makes them easy to compare: the same lines sit in the same order, and the % Daily Value column uses the same FDA reference amounts on both.

All figures are copied as printed, including the brands’ own spacing such as “1000mg” and “6g”.
Sodium, potassium and magnesium per stick
The sodium gap is the largest difference on the two panels. LMNT lists 1000mg of sodium per stick (43%), and Liquid I.V. Sugar-Free lists 500mg (22%). By our arithmetic, two Liquid I.V. sticks would match the sodium in one LMNT stick, at 1,000mg, and would bring 740mg of potassium with them.
Potassium runs the other way. Liquid I.V. lists 370mg (8%) and LMNT lists 200mg (4%). By our arithmetic, the sodium-to-potassium ratio on the panels is 5 to 1 for LMNT and about 1.35 to 1 for Liquid I.V.
Magnesium appears only on LMNT, at 60mg (15%). The Liquid I.V. panel has no magnesium line, and its ingredient list names no magnesium compound. If the magnesium line is what you are comparing, our magnesium label guide explains how food and supplement panels show it.
Each panel covers one stick. Per box, by our arithmetic, a 30-stick LMNT box lists 30,000mg of sodium in total and a 14-stick Liquid I.V. box lists 7,000mg. The box sizes differ, so compare per stick first.
Sweeteners and the ingredient lines
Both products show 0g Total Sugars, and both are sweetened. The ingredient lists name the sweeteners:
- LMNT Citrus Salt: Salt (Sodium Chloride), Citric Acid, Magnesium Malate, Potassium Chloride, Natural Lemon & Lime Flavors, Stevia Leaf Extract.
- Liquid I.V. Sugar-Free Lemon Lime: Allulose†, Citric Acid, L-Glutamine, L-Alanine, Potassium Citrate, Salt, Natural Flavors, Sodium Citrate, Silicon Dioxide, Stevia Leaf Extract (Rebaudioside A), Vitamin C (Ascorbic Acid), Vitamin B3 (Niacinamide), Vitamin B5 (Calcium D-Pantothenate), Vitamin B6 (Pyridoxine Hydrochloride), Vitamin B12 (Cyanocobalamin). The dagger note reads “adds a dietarily insignificant amount of sugar.”
So LMNT lists one sweetener, stevia leaf extract, and Liquid I.V. lists two, allulose and stevia leaf extract (Rebaudioside A). Ingredients on a food label are listed in descending order of weight under 21 CFR 101.4(a)(1), so allulose is the largest ingredient in the Liquid I.V. stick and salt is the largest in the LMNT stick.
That also explains why the carbohydrate line differs while both sugar lines read 0g. The FDA’s allulose guidance lets brands leave allulose out of Total Sugars and Added Sugars, but not out of Total Carbohydrate. Liquid I.V. shows 5g of Total Carbohydrate and LMNT shows 1g. Our monk fruit vs stevia vs allulose guide covers how each sweetener shows on a panel.
Stick weight, servings and mixing
An LMNT stick weighs 6g and a Liquid I.V. Sugar-Free stick weighs 13g, as each serving size line prints it. By our arithmetic, the Liquid I.V. stick is a little over twice the weight. Liquid I.V. says on its product page that it recommends mixing 1 stick with 16oz of water. A box of LMNT lists 30 servings and a box of Liquid I.V. Sugar-Free Lemon Lime lists 14.
Front-of-pack wording
The product names carry the sugar claim: LMNT sells Citrus Salt as Zero Sugar, and its panel image shows a “NO SUGAR” badge, while Liquid I.V. names the line Hydration Multiplier Sugar-Free. Under 21 CFR 101.60(c)(1), a sugar-free claim on a food that contains a sugar ingredient needs that ingredient marked with a note saying it adds a trivial or dietarily insignificant amount of sugar. On the Liquid I.V. list, the dagger after allulose points to that note. Our electrolyte label guide walks through the other conditions of the rule.
The LMNT panel image also shows “NO GLUTEN”, “VEGAN FRIENDLY” and “PALEO-KETO FRIENDLY” badges. The Liquid I.V. product page shows “Gluten Free” and “Non-GMO” badges. These are the brands’ statements; we have not checked them independently.
FAQ
Which has more sodium, LMNT or Liquid I.V. Sugar-Free?
LMNT, by the printed panels: 1000mg per stick against 500mg per Liquid I.V. Sugar-Free stick.
Does Liquid I.V. Sugar-Free contain magnesium?
The Lemon Lime panel we viewed has no magnesium line and no magnesium compound in the ingredient list. LMNT lists 60mg of magnesium per stick.
What sweeteners do they use?
LMNT Citrus Salt lists stevia leaf extract. Liquid I.V. Sugar-Free Lemon Lime lists allulose and stevia leaf extract (Rebaudioside A).
Why does Liquid I.V. Sugar-Free show 5g of carbohydrate but 0g of sugars?
Allulose is counted in Total Carbohydrate but, under FDA guidance, can be left out of the sugars lines. Allulose is the first ingredient on the Liquid I.V. list.
Are both sold as dietary supplements?
No. Both images show a Nutrition Facts panel, the panel for foods, not a Supplement Facts panel.
