Systems and methods for dispensing compositions, such as beverages, are provided. Beverage dispensers may be configured to receive one or more physiological parameters regarding a user, and in response, formulate at least one beverage recipe for dispensing. A beverage dispenser may wirelessly receive data from a biosensor. Environmental or biological data from the biosensor may be used to alter the recipe to another existing beverage or a custom beverage. Non-physiological data may also be considered. Exertion data may be calculated. The calculation of exertion data may receive inputs regarding at least one physiological parameter and/or non-physiological parameters to derive a second physiological parameter not being measured.
