Best Sugar-Free Electrolytes

Sugar-free is a label, not a formula. These four are all zero-sugar and completely different drinks — compare the sodium dose and the sweetener, not the claim. Liquid I.V. appears for its Sugar-Free line (allulose + stevia, ~510 mg sodium).

LMNT
1,000 mg Na · 200 mg K · 60 mg (malate) Mg
High-sodium, zero-sugar hydration for heavy sweaters, heat work and low-carb eating; the Raw Unflavoured version is a true no-sweetener option.

SALTT (by Keto Chow)
969 mg Na · 410 mg K · 178 mg Mg
People who compared LMNT's label and wanted more potassium and magnesium for less money — plus a genuinely unsweetened unflavoured option.

Ultima Replenisher
55 mg Na · 250 mg K · 100 mg Mg
Low-sodium, gentle everyday drinking and the best bulk-tub value in this comparison; includes all six electrolytes.

Liquid I.V.
500 mg Na · 370 mg K · 0 mg listed Mg
Everyday hydration and the easiest brand to find in stores; Sugar-Free swaps the 11 g sugar for allulose + stevia.
