On demand functional beverage dispenser

A method of controlling an amount of a flavored product and a functional product in a flavored mixture of the flavored product, the functional product, and a liquid that is dispensed from a beverage dispenser, the method comprising:

• receiving user input from a display of the beverage dispenser including a user interface, the user input identifying a selected flavor and a selected function, wherein the user input is received by a control system including circuitry configured to display the user interface;
• wherein the user interface has a flavor selection area and a function selection area;
• wherein the flavor selection area includes multiple selectable flavors and the function selection area includes at least one selectable functions;
• choosing from multiple selectable reservoirs a flavor reservoir based on the selected flavor;
• choosing from the multiple selectable reservoirs a function reservoir based on the selected function;
• supplying a liquid to a mixing receptacle by using the circuitry to control a liquid control valve based on the received user input;
• supplying the selected flavor from the flavor reservoir and the selected function from the function reservoir to the mixing receptacle to be dissolved in the liquid and form an enhanced flavored mixture by using the circuitry to control a mixture control valve based on the received user input;
• wherein a concentration of a dietary supplement included in the selected function that is included in the enhanced flavored mixture is larger than a concentration of the dietary supplement included in the selected flavor that is included in the enhanced flavored mixture;
• and
