A composition that includes at least one target supplement and at least one rehydration formulation is described. When the at least one target supplement is ingested as part of the composition, the bioavailability of at least one target supplement is enhanced as compared to when it is ingested separate from the composition. The at least one target supplement is absorbed more quickly and in a greater amount when it is ingested as part of the composition than when it is ingested separate from the composition. The composition also hydrates a subject.
