A system for selecting a prescriptive element based on user implementation inputs. The system includes at least a computing device and a prescriptive generator module operating on the at least a computing device. A prescriptive generator module is configured to receive at least a diagnosis descriptor from a user client device, receive prescriptive training data, and generate using a supervised machine-learning process a prescriptive model that produces an output containing a plurality of prescriptive elements. The system includes a loss function module operating on the at least a computing device. The loss function module is configured to receive from a user client device at least a user implementation response and generate a loss function as a function of the at least a user implementation response and the plurality of prescriptive elements. The loss function module minimizes the loss function and selects a prescriptive element as a function of minimizing the loss function. The loss function module transmits the selected prescriptive element to a user client device.
