PROBLEM TO BE SOLVED: To solve a problem that balance in a human body changes abruptly when intaking the product of the present invention and to provide a water and electrolyte supplement drink which does not become a burden for the body, the background of the problem being that, even though it is necessary to intake and replenish water and an electrolyte solution for life activity, it is necessary, when intaking and replenishing water and an electrolyte solution, to keep a water content and electrolyte concentration of the human body in certain balance and, when the balance is lost, to recover the balance and maintain homeostasis, and that an abrupt change in balance between the amount of water and electrolyte concentration of the human body when drinking water and activity to bring the balance to a normal state become a burden for the body and are not good for maintaining water and electrolyte.SOLUTION: The problem can be solved by relaxing the intaking rate of water and electrolyte when drinking water by providing a water and electrolyte supplement drink containing a guar rubber enzymolysis product and a fixed concentration of a sodium salt.SELECTED DRAWING: None
