Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate
Established adequate intake (AI) levels for daily total water: 3.7 liters (approx. 125 oz) for adult men and 2.7 liters (approx. 91 oz) for adult women from all foods and beverages.
Clinical Benchmark
Dispels the arbitrary '8 glasses a day' myth by defining biological hydration requirements based on metabolic mass, activity, and osmotic balance.
