Capsule filling systems and methods of using a capsule filling system to fill one or more capsules are described herein. An example embodiment of a capsule filling system comprises a first housing, a first rotatable member, a second housing, a second rotatable member, a hinge, and a base. The first housing defines a first housing cavity and the second housing defines a second housing cavity. The first rotatable member is disposed within the first housing cavity. The second rotatable member is disposed within the second housing cavity. Movement of the first rotatable member between its first and second positions provides a mechanism for releasably attaching a first member of a capsule to the capsule filling system. Movement of the second rotatable member between its first and second positions provides a mechanism for releasably attaching a second member of a capsule to the capsule filling system.
