Compare every electrolyte pack that matters
Most electrolyte marketing leads with a flavour. We lead with the dose: sodium, potassium and magnesium in milligrams, the sweetener by name, and the price per serving — side by side, for 19 brands.

Why the dose comes first
Two drinks can both promise "rapid hydration" while one carries twenty times the sodium of the other. Our comparison prints each electrolyte separately — here is how to read a label like we do.
Top picks by job
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.
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.
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.
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.
Nuun
300 mg Na · 150 mg K · 25 mg Mg
Light, portable, low-sugar daily hydration and travel — drop a tablet in a bottle, no stirring.
Pedialyte (Abbott)
330 mg (zero-sugar powder packet); 690 mg per litre (RTD) Na · 390 mg per litre (RTD) K · Not a feature Mg
Illness and children's rehydration — the clinical default with decades of use, plus freezer pops kids will actually take.
Shop by the job you're doing
For kids
Illness formulas are not everyday drinks, and everyday drinks are not illness formulas. We separate them.
Unsweetened & unflavoured
No stevia, no monk fruit, no "natural flavours" — the nothing-added shortlist for coffee, broth and sparkling water.
Budget & bulk
Tubs and pouches that bring a daily habit under $0.75 a serving.
Start with great water
Electrolytes go into water you already like drinking. Our sister site CountertopFilter covers filtration first — making tap water taste good enough that a daily drink is easy to keep up.
