A package for transferring a powdered nutrient from the package into a water bottle without spilling the powdered nutrient during the process of transferring is disclosed. The package has an end portion which is sufficiently small to be inserted into the neck of the water bottle and the main portion which is sufficiently large so that the main portion cannot be inserted into the neck of the water bottle. To transfer the powdered nutrient from the package into the water bottle, the end portion is torn to create an opening through which the powdered nutrient is emptied from the package. The end portion is inserted into the neck of the bottle and an edge or step between the end portion and the main portion rests on an edge of the neck as a powdered nutrient is poured into the water bottle. Any remaining powdered nutrient in the package is transferred into the water bottle by lightly shaking the package.
