A method of promoting increased cellular hydration in a multicellular organism that is capable of intracellular water permeation includes the step of causing the multicellular organism to ingest an aqueous solution that contains an amount of a carbohydrate clathrate component. There is also a step of enhancing the intracellular permeation. The multicellular organism contains aquaporins, and the causing step involves interaction of the composition with the aquaporins. The cellular hydration promoted and caused by the method is corroborated by a test that uses human-aquaporin-expressed frog oocytes. The test uses single cell Xenopus laevis frog oocytes having expressed human aquaporin AGP1 water channels. There is also a beverage composition that increases lifespan in the multicellular organism, and a beverage composition that promotes cellular hydration when ingested by a multicellular organism.
