All brands, dose first
19 brands and product families, each profiled on the same fields: sodium, potassium, magnesium, sugar, sweetener, format and price per serving. Label figures, checked Oct 2026 — see How we compare for what that means.
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.
Gatorade / Gatorlyte / Propel
~160 mg (classic RTD, per bottle serving) Na · 45 mg K · Not a feature Mg
Cheap, everywhere sports hydration; Gatorlyte and the powder lines run materially higher in electrolytes than classic ready-to-drink.
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.
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.
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.
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.
Waterboy
Sold on total electrolytes — read the panel Na · See label K · See label Mg
Occasion-based packs — Daily, Workout and Weekend Recovery — if you like buying for a specific moment.
BodyArmor / Flash I.V.
Varies — lower than LMNT-class sticks Na · A selling point (coconut-water based) K · Varies Mg
Shoppers who prefer a potassium-and-coconut-water profile from a mainstream sports-drink brand.
Prime Hydration
~10–25 mg (typical, per category comparisons) Na · Coconut-water based K · Not a feature Mg
A flavoured coconut-water drink from the convenience fridge.
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.
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.
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.
Skratch Labs
400 mg Na · 50 mg K · 50 mg Mg
Endurance training where the sugar is fuel, not a flaw — real-fruit flavours and a gentle-on-the-stomach reputation.
Redmond Re-Lyte
~800 mg class Na · ~400 mg class (2:1 marketing) K · Present — check the label Mg
Low-carb and keto shoppers who want a high-sodium, unrefined-salt formula, and families — there is a kids version (see our kids guide).
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.
Vitassium / SaltStick (Alete)
500 mg per 2 capsules Na · 100 mg per 2 capsules K · — Mg
People whose clinician has advised a high daily sodium intake and who prefer capsules to drinking litres of salty water; classified as a medical food for the dietary management of certain conditions, used under medical supervision.
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.
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.
