Buying Guide

Choose the potassium form

Potassium citrate, chloride, and iodide have different uses—pick citrate for general supplementation, chloride for electrolyte replacement, and iodide when iodine is also needed

Check elemental potassium per serving

Compare milligrams of elemental potassium per capsule, tablet, or scoop to match your target intake without exceeding guidance from a clinician

Consider serving count and price per serving

Higher capsule/tablet counts or multi-pack electrolytes can stretch value for regular use; divide price by servings to compare cost-effectiveness

Watch supporting ingredients

Electrolyte powders and tablets may include sodium, magnesium, sweeteners, or multivitamins—confirm these align with hydration or dietary goals

Match format to use case

Choose capsules for measured daily dosing, tablets for on-the-go cramp relief, and powders for customizable hydration during exercise
