Format guide · no universal winner
Electrolyte capsules vs. powders.
Capsules win on simplicity. Powders can make fluid, flavour, and—in some formulas—carbohydrates part of the same routine. The better format is the one that fits the job and that you will use correctly.
| Factor | Capsules | Powders |
|---|---|---|
| Setup | Swallow with water | Measure or empty a packet into water |
| Taste | Usually neutral | Flavoured or unflavoured, depending on product |
| Fluid reminder | Easy to separate from drinking | Prepared as a drink, so fluid is built into use |
| Carbohydrates | Typically little or none; verify label | Ranges from zero-sugar to carbohydrate-containing |
| Portability | Very compact | Single sticks are compact; tubs are less convenient |
| Adjustment | Often adjusted capsule by capsule | Often adjusted by powder or water concentration—follow directions |
Choose capsules for
Fast, neutral, compact use
They suit people who do not want a sweet or flavoured bottle and are comfortable managing water separately. Our founder's SaltStick use supports the convenience case, but it does not establish a universal performance advantage.
Choose powders for
A drink-first routine
Powders suit people who prefer sipping a prepared drink or want a particular flavour, sodium level, or carbohydrate profile. Read each label: “powder” describes the format, not one standard formula.
Two examples show the range
LMNT currently lists 1,000 mg sodium, 200 mg potassium, 60 mg magnesium, and no sugar per stick. Nuun Sport Powder currently lists 300 mg sodium, 150 mg potassium, 25 mg magnesium, and 1 g sugar per stick. Those are manufacturer-reported label facts, not our test results—and they demonstrate why format alone cannot tell you what is inside.
Our decision rule
Start with the session: duration, heat, sweat, access to water, and whether you need fuel as well as electrolytes. Then compare serving size, sodium, carbohydrate, directions, and cost per real-world use. Do not concentrate a powder beyond its instructions just to chase a bigger number.
