Agents for recoverying from or preventing fatigue in the central nerve system and foods for recoverying from or preventing fatigue

摘要

The present invention provides a fatigue-preventive (brain fatigue) agent or a fatigue-recovering agent for the central nervous system, which contains a branched-chain amino acid, such as L-valine, L-leucine and L-isoleucine, and/or a 2-aminobicyclo-[2,2,1]-heptane-2-carboxylic acid. In addition to the application as injection and transfusion, these can be prepared as solid-state modes to be taken, such as tablets, pellets and powder medicine by adding an appropriate vehicle such as starch and lactose thereto. Moreover, these can be prepared as various beverages such as so-called health drinks and sports drinks, or as food items for fatigue-recovering and the fatigue-prevention in the central nervous system.
