Abstract: The present invention relates to compositions which provide an onset and steady maintenance of energy to the consumer, as well as kits comprising the compositions and methods of using the compositions. In particular, the compositions of the present invention comprises a select mixture of carbohydrates which provides immediate and sustained energy when consumed. The compositions may optionally, but preferably, comprise one or more bracers and/or flavanols which, in combination with the foregoing select mixture, provide sustained energy and mental alertness without nervousness or tension.

Abstract: The invention relates to a process for working additives into polymers, in which a mixture of thermoplastics with additives is heated to a temperature sufficient for the melting process, with the possible introduction of an expanding agent into the melt in which the expanding agent is homogenized, the melt being cooled if necessary to a temperature at which it can be extruded in the form of a foam plastic, the additives being adsorbed on a polymer flocculent matrix having a sufficient specific area, due to having a density of up to 0.6 g/cm.sup.3 and 15 to 99% of open foam cells and being of the same or different polymer composition as the basic polymer.
