Buying Guide

Choose the right form

Capsules, tablets, and powders absorb differently and fit lifestyles—capsules like potassium citrate suit daily supplementation while tablets and powders are geared to hydration and workout recovery

Check potassium source and dose

Look at the compound (e.g., potassium citrate) and per-serving milligrams to match clinical needs or clinician guidance rather than relying solely on serving count

Prioritize electrolyte balance

Products labeled as electrolyte powders or tablets often include sodium and magnesium in addition to potassium, which can improve rehydration and cramp relief

Watch for sugar and calorie content

If you need low-calorie hydration, opt for no-sugar, calorie-free electrolyte powders or sugar-free tablets to avoid added carbohydrates

Consider dietary sensitivities

Choose gluten-free or allergen-friendly formulas when needed; some options explicitly list gluten-free or minimal excipients
