Which electrolyte is right for you?
Three questions, honest matches from the brands we compare. We don't sell electrolytes — every recommendation below is an existing brand you can buy anywhere.
Your matches
For heat work you want real sodium, sugar-free options and a price that survives a whole crew.
Sqwincher
Activity-based — varies by format Na · Varies K · Varies Mg
Workplaces: the industrial standard for heat-stress hydration, in sticks, cooler concentrate and freezer pops, priced per worker rather than per wellness serving.
DripDrop
330 mg (small stick) — larger sticks 670–780 mg Na · 185 mg K · 39 mg Mg
Oral-rehydration-style formulas used by firefighters, medical teams and outdoor crews; sugar and sugar-free lines.
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.
Your matches
For a gentle daily drink, a low-to-moderate dose beats a salty bolus — and start with small sips.
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.
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.
Cure Hydration
Varies by flavour — check the label Na · Varies by flavour K · Varies by flavour Mg
People who want an oral-rehydration-style ratio from plant-based ingredients, with no added sugar.
Your matches
For high sodium, these are the full-strength options. If a clinician advised your sodium intake, check the plan with them.
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.
Precision Fuel & Hydration
250–1,500 mg by strength Na · Varies by strength K · Varies by strength Mg
Endurance athletes who sweat-test and want to choose a sodium strength — 250, 500, 1,000 or 1,500 mg — rather than one fixed dose.
Your matches
For children, start with the kids guide — illness formulas and everyday drinks are different products with different doses.
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.
Your matches
For truly nothing added, these are the unsweetened options that disappear into coffee, broth or sparkling water.
Hydrant
Balanced — check the label Na · Balanced K · Present, with zinc Mg
The truly-nothing-added shopper: an unflavoured, unsweetened pouch at a bulk price, for water, coffee or broth.
Buoy
50 mg (Regular); 300 mg (Rescue) Na · 10 mg (Regular) K · 0.5 mg (Regular) Mg
Adding a light electrolyte lift to any drink you already like — coffee, tea, water — with nothing sweet or flavoured added.
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.

If you take medication that affects sodium or potassium, are pregnant, or are choosing for a child who is ill, a clinician's guidance beats a quiz — ours included.
