Hydration Calculator

In February, 2004, the National Academy of Sciences (NAS) issued a report on the Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate that estimates an adequate daily intake level of water for women of 91 ounces and 125 ounces for men. The report further stated that about 80% of the estimated total water intake is met by consuming water and beverages, while the other 20% is derived from foods.

While the NAS report mentions water and beverages, bottled water is an excellent choice for hydration for those who enjoy its refreshing taste and consistent high quality and safety, and for consumers wishing to avoid or moderate calories, caffeine, sugar, artificial colorings or other additives.

The amount of water you need to be adequately hydrated varies depending on your temperature, weight, level and duration of exercise, and many other factors. We offer this handy tool that will calculate a recommended water intake guideline that is tailored to your individual needs. Remember, this is only an estimate. You will also receive a schedule of the best times of day to fulfill your daily hydration requirements.
