Buying Guide

Choose the right potassium form

Potassium citrate (as in capsule products) differs from potassium in electrolyte tablets or powders—citrate is commonly used for supplementation while electrolyte mixes combine potassium with sodium and other minerals for hydration

Check serving potassium amount

Compare milligram amounts per serving or capsule to match your target intake—capsules typically list per-capsule mg while powders/tabs list per serving

Consider delivery format

Capsules suit daily supplementation and portability; effervescent tablets and powders support rapid hydration and cramp relief during exercise or dehydration

Look for added ingredient flags

If you have dietary restrictions, note labels such as gluten-free, no-sugar, calorie-free, or multivitamin blends to avoid unwanted additives

Compare value by capsules/servings

Assess cost-effectiveness using price per capsule or per serving rather than package price to find the under $50
