Buying Guide

Choose the right potassium form

Potassium citrate, chloride and iodide have different uses—citrate is common for general supplementation, chloride for electrolyte balance and cramps, and iodide for iodine support

Check per‑serving elemental potassium

Compare the mg of elemental potassium per capsule or serving to match your target intake without exceeding clinical recommendations

Pick delivery format for your lifestyle

Capsules suit daily maintenance, tablets are convenient for travel, and powders/tablets dissolved in water can aid hydration and workout recovery

Watch sugar and calorie content

Sugar‑free and zero‑calorie electrolyte powders provide potassium without added sugars or calories for tighter dietary control

Consider specialty tags and uses

Look for tags like cramp‑relief, hydration, or emergency/radiation support to match specific needs such as athletic use or iodine supplementation
