Abstract: A nutritional supplement dispenser for attachment to a bicycle frame or to a runner's belt has a hollow case with an openable top for placing tablets in the case and an inclined bottom tending to urge tablets forward under the influence of gravity. A dispenser located at a low point of the case dispenses a single tablet into an athlete's hand when manually depressed. VELCRO® brand fastener-equipped straps attach the case to the top tube and down tube of a bicycle or to a belt worn by a runner. Magnetically biased and spring biased dispensing mechanisms are described. A push-button dispensing mechanism is described. Bicycle-frame-conforming aerodynamic wings and a holster are described.
