The invention relates to branched chain amino acid granules which comprise branched chain amino acid powder, a coating agent and a corrigent. As the outer layer of the branched chain amino acid powder is coated with the suitable coating agent and corrigent and the grain size of the branched chain amino acid granules ranges from 400 micrometers to 600 micrometers intensively, with the bitter taste hidden, the branched chain amino acid granules can dissolve in water rapidly and can be taken as a medicine or nutritious supplementary with good compliance.
