This hydration calculator is based on scientific studies and provides an estimate only of fluid requirements under the above conditions. Fluid loss varies from person to person and this calculator should be used only as a guide. Those who exercise in extensive conditions or at high intensity for prolonged duration may need more fluids and should use their sweat rate to guide fluid intake. Check out the Hydration information for more detail.

POWERADE ION4 contains electrolytes and carbohydrates, in addition to the fluid, which can help you replace what has been lost in sweat, and burned through exercise. You should consider the additional ingredients in POWERADE ION4 in the context of your total food consumption and your individual exercise or sporting needs.
