Abstract: A beverage and supplement system comprises a beverage container having: i) a liquid contained therein; and ii) a dispensive opening. A container lid is coupled to the container adjacent the dispensive opening. An envelope is contained within the container lid, the envelope being in communication with the dispensive opening of the container and having a first side sealed to a second side with said supplement being contained therebetween. The second side of the envelope is rupturable upon application of force to said first side in order to dispense said supplement from the envelope without contacting said supplement with an external object. A removable protective cover is positionable on the container lid, the protective cover restricting access to the envelope when positioned on the container lid.
