A hydration container includes a bottle having a selected volume and a bottle cap which includes a drinking nozzle. An indicator bearing a sequence of numbers is moveably mounted to the cap so that any one of the numbers in the sequence may be positioned opposite an index on the cap. Preferably, the numbers on the indicator are coordinated with numbers in a recommended daily fluid intake table present on the bottle. Thus when the user increments or decrements the indicator each time the bottle is refilled with fluid, the container will indicate in real time the user's approximate actual fluid consumption versus the intake goal indicated by the table.
