Buying Guide

Check potassium per serving

Look for a clear potassium amount on the label since effective cramp support depends on adequate milligrams per serving

Consider sugar and calories

Sugar-free or zero-calorie formulas can rehydrate without added carbs, useful for workouts or glucose-sensitive users

Evaluate electrolyte balance

A mix of sodium, magnesium and potassium supports rehydration and muscle function better than potassium alone

Compare serving counts

Calculate cost and value by dividing container size by servings to understand how long a tub will last

Mind flavor and mixability

Flavor options and unflavored powders affect adherence—unflavored for flexibility, flavored for palatability during exercise
